Launch Vehicle Summary:

Statesville Christian’s rocket will consist of 3 inch fiberglass tubing and will be approximately 72 inches long. The team will be using a Cesaroni K-1440 as the main thrust motor and possibly an Aerotech G-12 or Ellis Mountain G-33 as the reverse Thrust motor. The recovery system will be drogueless dual deployment with a Loki ARTS II altimeter and 72 inch parachute as the main.

Payload Summary:

The scientific payload for our rocket consists of a reverse thrust motor, of G or F impulse, in the nose cone of the rocket that will fire as the rocket travels transonic. We will measure the change in pressure along the outer body of the rocket through the use of four pressure sensors to determine if the hot gases from the reverse thrust motor reduce the shock wave seen as the rocket travels transonic.

II. Changes made since Proposal

The rocket and scientific payload that Team Statesville designed for the proposal has changed little since its initial design. The rocket will still consist of 3 inch fiberglass tubing but will be shortened to a length of approximately 72 inches and a maximum mass of approximately 10 lbs. We have decided to use a Cesaroni K1440 motor due to its quick time till full pressure and simplicity in use. Flying on a K-1440, the rocket will now reach an approximate altitude of 8500 feet and a velocity of Mach 1.3. The reverse thrust motor’s effect on the altitude and velocity is negligible.

The electronics payload as stipulated in the initial proposal has not changed. We have narrowed our search for a reverse thrust motor to either an Aerotech R/C 32mm G motor or an Ellis Mountain G. The fallback plan is to use the Apogee F10 like last year if necessary.

We are still on schedule with the milestones presented in the initial proposal and have not seen a reason so far to change the costs estimates for our rocket. The outreach plan has also not changed since the proposal.

III. Vehicle Criteriaa. Selection, Design, and Verification of Launch Vehicle

i. Mission Statement: The Statesville Christian rocket team will successfully launch a rocket to transonic speeds and successfully recover the rocket and data to determine if the effect of Mach is reduced when traveling through a cloud of hot gas.

ii. Requirements and Mission Success Criteria: The main requirement is the construction of a rocket that will reach apogee close to one mile and travel faster than Mach 1.0 with recovery as specified. Secondary requirements include ensuring the reverse thrust motor is aligned along the axis of the rocket, selecting a reverse thrust motor with no ejection charge, and ensuring the electronics can withstand the expected high “g” flight. For the mission to be a success, we must meet our requirements and be able to analyze our data to determine if Mach effects were reduced using our reverse thrust method.

iii. Major Milestone Schedule:This is in section V (Activity Plan) section of this review paper

iv. System Level Design:The rocket is three inches in diameter using fiberglass tubing along the body for strength. The motor mount is a 54 mm inside diameter with a Slimline Retainer used for negative retention. Four centering rings will be used for the motor mount. Fins will be of an isosceles trapezoid design similar to that of a Nike Smoke and will be constructed from G10 fiberglass. This design is for reduction of drag at high speeds. Fins will feature thru-the-wall construction with fiberglass fillets for the fins inside and outside of the rocket body. The nose cone will be a fiberglass boat tail sized to fit the body tube and reverse thrust motor. This should be much stronger than last year’s nose cone and provide high strength to secure the reverse thrust motor. Two ARTS II altimeters will be used for the safe recovery of the rocket. The primary altimeter will ignite a charge at apogee and the redundant altimeter at apogee +1 second. The primary altimeter will ignite the second charge at 1000 feet and the redundant altimeter at 800 feet. The motor will also provide an ejection charge near apogee. The dual deployment recovery will be drogueless at apogee and use a 72 inch parachute as the main with 15 foot long Kevlar shock cords. The rocket will use launch rails for strength as the rocket leaves the launch pad. The altimeter payload section will be based on a LOC Precision payload bay design. Shear pins will be used to keep the rocket together through Mach and will be slightly larger this year to prevent drag separation. A Rocksim drawing of the rocket is shown below.

v. Verification Plan:We have designed a half scale model that will fly on a G80 or G77 to test the stability of the design and the reverse thrust motor mounting and firing technique. A Rocksim 2-D drawing is shown below. We plan to fly this rocket by the end of December. The full-scale rocket will be constructed in January through February with plans to fly in March to test for stability and acquire baseline data for a flight going through Mach without the effects of the reverse thrust motor. We are currently on schedule with our verification plan

vi. Risks and Testing Plans to reduce RiskThere are many risks to this rocket failing. Based on last year’s experience, the main issues are preventing drag-separation, electronic payload recovery and allowing time to complete the project.

The major failure mode last year was the drag separation coming out of Mach due to shear pin failure. We plan on using larger shear pins this year and also plan to watch our fit and finish at the coupler/body tube interface to make sure that there is no gap to possibly break the pins when the rocket first leaves the launch pad.

b. Recovery Subsystem

The recovery system will involve two Loki ARTS altimeters for a dual deployment drogue less recovery. Details for this technique are in the system design section of the rocket.

c. Mission Performance Predictions

The predictions for the flight of the rocket are 8500 feet of altitude, Mach 1.25 to 1.30 for maximum velocity, approximately 40 g’s of acceleration off the launch pad and a rocket with a mass of approximately 10 lbs. This is within the bounds to meet our scientific payload objective.

d. Payload Integration

The team’s project requires that wires run from the top of the rocket to the bottom of the rocket to allow for the data sensors as well as a connection to the launch system. Team Statesville plans on running small tubing along the inside length of the rocket to provide a place for the wires.

e. Launch Operation Procedures

Because of team Statesville’s project, two launch systems must be used. One to control the main thrust motor, and another to ignite the reverse thrust motor. The two are on separate ignition systems in case the reverse thrust motor does not ignite.

Outline for final assembly and launch procedures-

First, the team will prepare the recovery system. Dr. Knight will then make the ejection charges. Next the altimeters will be installed in the payload altimeter bay. Once in place, the ejection charges will be placed in the rocket and attached to the altimeters. Then the parachute will be loaded into the rocket.

Secondly, the motor will be prepared. Dr. Knight will insert the Cesaroni into its casing. The instructions will be followed step by step and then the closures will be tightened. It will then by friction fit into the rocket. After complete, the slimline retainer will be will be attached to the motor mount, providing negative retention on the motor. Next the reverse thrust motor will be inserted into the nose of the rocket.

Next, The igniters will be installed. Dr. Knight will install the igniters, following all the manufactures instructions.

Fourthly, the rocket will be set up on the launch rail. When the rocket is in place, the altimeters will be turned on. Next, the reverse thrust motor will be attached to the launch system. Once complete, the burn sensor will be placed across the top of the rocket. The main thrust motor will then be attached to the launch system and the continuity will then be tested.

When everything is complete, a countdown will commence. At T-2 seconds, the launch button for the reverse thrust motor will be pressed and the reverse thrust motor will ignite. At T-0 seconds the main launch button will be pressed and the rocket will fire assuming the reverse thrust motor ignites and the fail-safe works as expected.

f. Safety and Environment (Vehicle)

The safety of all participants working on the project is of vital importance and will be the first priority of this team. During all the steps in this process, including the construction, testing and launching of rockets, all team members shall abide by the safety procedures set down by the NAR and TRA. All team members shall abide by posted safety guidelines during the construction and testing of the rocket as well as the testing of all its components. Each member of the team shall receive guidelines for the usage of materials that may be harmful if used improperly. A copy of these guidelines is included in the appendix. (See Appendix A, MSDS) Immediately preceding any meeting in which any construction or testing shall occur, the team shall be briefed by the safety officer, Philip Christiansen, on the proper and/or safe use of the necessary equipment.

The purpose of the safety officer is to make sure that all proper safety procedures are followed correctly, during construction of the rocket and in the testing and launching of the rocket. The safety officer for this project is Phillip Christianson. The safety officer will provide information to the other members of the team on how to properly utilize the available equipment to avoid mishap. After providing the information, the safety officer and Dr. Knight, the adult supervisor, will administer a test to the members of the team concerning safety issues. Before a team member can participate in construction, testing, and launching of the rocket, a perfect score must be achieved on this test. It is also the job of the safety officer to brief the team on the safety codes of the NAR and TRA along with any other safety issues that arise. This is vitally important as it ensures the safety of all involved in the launch. Dr. Knight and Mark Ford will oversee the safety officer in the performance of his duties and also be responsible for safety precautions during the construction, testing, and launching of the rocket.

Dr. Doug Knight will be the NAR/TRA mentor. He is affiliated with the local NAR/TRA chapter (Rocketry of the Central Carolinas, ROCC) and the South Carolina NAR/TRA chapter (Tripoli South Carolina, ICBM) and is currently Level 2 certified high power. He is also working on his Level 3 certification with TRA.

The area designated for the use of the team is the high school chemistry lab. All materials will be stored in conditions according to the directions issued by the manufacturer. All power tools will be unplugged when not in

use, and when the group is not using the equipment, it will be stored safely so that others who may use the space shall not injure themselves.

Scale models will be flown with G or H impulse level or lower and may require a Low Explosive Users Permit (LEUP) for handling. Dr. Knight is Level 2 TRA certified and has a LEUP and will handle the scale model motor and other high power motors at the rocket launch sites. Scale models will be launched at the Midland, NC field of Rocketry of the Central Carolinas (ROCC) or at the Orangeburg, SC field of Tripoli, SC. Both clubs apply and receive a FAA waiver during their launches and the team will easily comply with their altitude requirements. Dr. Knight and Mr. Ford will oversee all scale model launches and the Range Safety Officer (RSO) must consider the rocket flight worthy before it is launched. The launch will be conducted by the RSO and Launch Control Officer (LCO) at the launch site for flying the rocket. Launch safety guidelines will be followed which ensures compliance with NAR safety requirements. Those certified to handle black powder and high power rocketry motors will be the only persons to handle any hazardous materials. Both local prefects are in compliance with local environmental laws and regulations and have never been cited for a violation. 

General Safety Procedures:

At no point shall a team member be working alone. At least two people are required for any work, whether it is constructions or launching, that occurs.

Team members will wear safety goggles at all times during the construction and launching of the rocket.

Protective gloves shall be worn while using cutting tools. Earplugs shall be utilized during the operation of loud equipment. A mask shall be used if there is noticeable or expected dust in the air. The work are shall be ventilated when epoxy or cyanoacrylate is used. Gloves shall be worn when any more than a small amount of epoxy or

cyanoacrylate is used. While curing, all flammable materials shall be kept away from the epoxy.

During launch prep, electronic devices will have switches to prevent accidental firing of the ejection charges and the firing of the reverse motor. Avionics will be armed only after approval from the safety officer and Dr. Knight.

Dr. Knight will handle all black powder and ejection charge preparation. Material Safety Data Sheets (MSDS) are included in the Appendix for the

solid motor propellant, igniters, black powder, West Systems Epoxy, and cyanoacrylate and will be given to each team member.

IV. Payload Criteriaa. Selection, Design, and Verification of Payload

Experiment

Our scientific payload design has not changed from the initial proposal; except for reducing the reverse thrust motor of G-12 impulse. Since the rocket will only be transonic for a few seconds, it is very important that we collect enough data within this time to detect any possible reduction in pressure from the hot gas surrounding the rocket. The XBee Pro module and the Loki ARTS II altimeters can easily sample fast enough (minimum 100 Hz) to detect the changes in pressure we are hoping to see. Last year’s electronic design met our goals and with the increase in sensors to four, this should enhance our abilities to meet the requirements.

The XBee Pro 2.4 GHz RF communication module will be used along with 4 pressure sensors positioned along the length of the rocket to collect separate pressure readings from multiple points on the rocket. This will allow us to record the displacement of the shock wave and the effect of dissipation of the exhaust on the shock wave on the rocket. This technique worked successfully last year during the flight of the rocket until the payload section separated from the rocket. We plan on using a similar method this year but increasing the data stream due to extra pressure sensors. The range of the Xbee modules is one mile and we are researching ways to increase this range to extend our data collection capabilities.

A possible failure mode for our payload is the ignition of the main motor and launch of the rocket without the ignition of the reverse thrust motor. This occurring would negate the scientific value of the flight. To prevent this, the communications system will also function as a failsafe device to prevent ignition of the main engine if the reverse thrust motor fails to ignite. A very thin-gauge wire will be mounted as a closed-loop over the nozzle of the reverse thrust motor. This wire will be used to monitor and confirm the successful ignition of the reverse thrust motor.10 The receiver module will read a closed loop until the reverse thrust motor ignites and burns the wire and opens the circuit. The receiver module will be designed so that current cannot flow to the main igniter from the ignition source until the confirmation of the successful ignition of the reverse thrust motor. Alligator clips from the primary (NASA) ignition system will attach to wires at the base of the rocket that are connected to the receiver module. Two other wires connected to the receiver module will be attached via alligator clips to the igniter for the main engine.

b. Payload Concept Features and Definition/Science Value

The reverse thrust motor is a critical part of the scientific payload. It will be enclosed at the top of the rocket using a conical fiberglass nose cone with the top cut off to secure the 38 mm diameter motor. An engine mount with positive and negative retention will be constructed inside the nose cone. The motor will not have an ejection charge so that a heavy baffle system as used in last year’s design is unnecessary. The engine mount will also be aligned so that the motor’s longitudinal axis is along the same axis as the rocket. This is to prevent possible off-axis forces pushing on the rocket during flight caused by the reverse thrust motor. This could possibly make the rocket go unstable. The motor of choice will be a G-12 motor because it has no internal ejection charge and an 8 second burn time.

The central idea for this project is based on several papers regarding plasma and hot gas counter-flow injection out of the front of a rocket. Combining these ideas, the group decided to use the idea of hot gas injection ejected into the air in front of the rocket for counter-flow injection. While not a completely new concept, we did not find any instances of using the exhaust plume of a rocket engine as the basis for the hot gas injection; the idea we intend to test. Since a solid propellant Ammonium Perchlorate based model rocket engine produces hot gas out of the nozzle in excess of 1000 K, the decision was made to use a long burning hobby rocket engine as the source of the hot gas. Since this technique should result in the rocket traveling through less dense air than without the counter-flow injection, the Mach shock wave should be reduced relative to no hot gas injection which is the basis of our hypothesis.

Much work has been performed regarding methods to reduce the shock wave as aerodynamic bodies pass through Mach. This is an issue for both military and commercial designers. While not a breakthrough idea, the concept could possibly be used for an aircraft, rocket, missile, mortar or other device as it travels through Mach. The effect on the projectile would be less and the effect on the environment would be reduced. This could be a positive feature for stealth or noise reduction.

The rocket engine used for the hot gas injection is motor of less than 1% of the thrust of the main engine and should have little effect on our flight predictions from Rocksim. The electronics to remotely trigger the reverse thrust motor before the main is fired uses off the shelf technology and circuitry taught in high school level electronics courses. The rocket is of the same design as previously presented and is within the skill level of this group of students.

c. Safety and Environment (Payload)

Safety for the payload will entail similar requirements to safety with the rocket design. Please see the section on Safety for the rocket design for this information.

V. Activity Plan

a.Budget Plan

We have made no changes in our budget since the initial proposal. We do believe we can get some parts donated for the rocket and payload electronics, which will reduce our overall cost. Also with the reverse thrust motor now being of G or F impulse, that lowers cost for that item.

b.Timeline

We are on time with our timeline. We have postponed doing the payload electronic and component testing since we plan on using the same electrical components and chip as last year but just add three more pressure sensor gages. The scale model rocket has been completed in RockSim and parts will be order by the end of this week, the last week in November. We have had some trouble with our web domain name but should have it cleared up by the time this report is submitted.

LD50 = 20,000 mg/kg (skin absorption in rabbits)West System Inc. Page 4 of 5 WEST SYSTEM® 105™ ResinMSDS #105-05b Last Revised: 13OCT05TERATOLOGY: ...................................………………Diglycidyl ether bisphenol-A (DGEBPA) did not cause birth defects or other adverse effects on the fetus when pregnant rabbits were exposed by skin contact, the most likely route of exposure, or when pregnant rats or rabbits were exposed orally. Ethylene glycol monobutyl ether (present at < 0.3 %) causes harm to the fetus in laboratory animal studies. Harm to the fetus occurs at exposure levels that harm the pregnant animal. The relevance of these findings to humans is uncertain.REPRODUCTIVE EFFECTS: ..............……………….DGEBPA, in animal studies, has been shown not to interfere with reproduction.MUTAGENICITY: ...............................……………….. DGEBPA in animal mutagenicity studies were negative. In vitro mutagenicity tests were negative in some cases and positive in others.CARCINOGENICITY:NTP .............................................................................Product not listed.IARC ...........................................................................Product not listed.OSHA..........................................................................Product not listed.Many studies have been conducted to assess the potential carcinogenicity of diglycidyl ether of bisphenol-A. Although some weak evidence of carcinogenicity has been reported in animals, when all of the data are considered, the weight of evidence does not show that DGEBPA is carcinogenic. Indeed, the most recent review of the available data by the International Agency for Research on Cancer (IARC) has concluded that DGEBPA is not classified as a carcinogen. Epichlorohydrin, an impurity in this product (<5 ppm) has been reported to produce cancer in laboratory animals and to produce mutagenic changes in bacteria and cultured human cells. It has been established by the International Agency for Research on Cancer (IARC) as a probable human carcinogen (Group 2A) based on the following conclusions: human evidence – inadequate; animal evidence – sufficient. It has been classified as an anticipated human carcinogen by the National Toxicology Program (NTP).12. ECOLOGICAL INFORMATION:Prevent entry into sewers and natural waters. May cause localized fish kill.Movement and Partitioning: Bioconcentration potential is moderate (BCF between 100 and 3000 or Log Kow between 3 and 5).Degradation and Transformation: Theoretical oxygen demand is calculated to be 2.35 p/p. 20-day biochemical oxygen demand is <2.5%.Ecotoxicology: Material is moderately toxic to aquatic organisms on an acute basis. LC50/EC50 between 1 and 10 mg/L in most sensitive species.13.

FIRE FIGHTING MEASURES:FLASH POINT:................................................................... > 200°F (Open Cup)EXTINGUISHING MEDIA: ..................................................Water spray, dry chemical, alcohol foam and carbon dioxide (CO2).FIRE AND EXPLOSION HAZARDS:.................................. Burning can generate toxic fumes. When mixed with sawdust, wood chips, or other cellulosic material, spontaneous combustion can occur under certain conditions. If hardener is spilled into or mixed with sawdust, heat is generated as the air oxidizes the amine. If the heat is not dissipated quickly enough, it can ignite the sawdust.SPECIAL FIRE FIGHTING PROCEDURES:...................... Use full-body protective gear and a self-contained breathing apparatus. If spill has ignited, use water spray to disperse vapors and protect personnel attempting to stop leak. Use water to cool fire-exposed containers.6. ACCIDENTAL RELEASE MEASURES:SPILL OR LEAK PROCEDURES: Stop leak without additional risk. Wear proper personal protective equipment. Dike and contain spill. Ventilate area. Large spill - dike and pump into appropriate container for recovery. Small spill - dilute with water and recover or use inert, non-combustible absorbent material (e.g., sand) and shovel into suitable container. Do not use sawdust, wood chips or other cellulosic materials to

absorb the spill, as the possibility for spontaneous combustion exists. Wash spill residue with warm, soapy water if necessary.7. HANDLING AND STORAGE:STORAGE TEMPERATURE (min./max.): ......................... 40°F (4°C) / 90°F (32°C).STORAGE: ......................................................................... Store in cool, dry place with adequate ventilation.HANDLING PRECAUTIONS: .............................................Use only with adequate ventilation. Do not breath vapors or mists from heated material. Avoid contact with skin and eyes. Wash thoroughly after handling. When mixed with epoxy resin this product causes an exothermic reaction, which in large masses, can produce enough heat to damage or ignite surrounding materials and emit fumes and vapors that vary widely in composition and toxicity.8.

VI. HEALTH HAZARD DATA:Possible routes of entry include skin and ingestion.

This product is not included on any list for carcinogenicity.

WARNING:    Eye irritant. Bonds skin in seconds. Contains cyanoacrylate ester. This adhesive gives a virtually immediate, strong bond: apply only to surfaces to be bonded. Do not get adhesive on your skin or other parts of your body, or that of others. In case of body contact, flush with water. Seek medical attention for any eye or internal contact.

LIQUID EFFECTS:

EYE CONTACT:   Cyanoacrylate adhesives are eye irritants and tissue bonders. Therefore, care, including the use of goggles, should be taken to prevent eye contact. In the event of eye contact, the eyes should be copiously flushed with water and medical aid sought immediately. If eyelids are bonded closed, only a qualified physician should attempt to separate them. In case of bonding corneal surface, forced separation is not recommended. Allow the eye to remain closed and the bond to separate naturally, which generally will occur within a few days.

SKIN CONTACT:   Cyanoacrylate adhesives, while relatively non-toxic, are mild irritants to the skin. The Acute Dermal LD50 is >2000 mg/kg. However, strong bonds will quickly form between adjacent skin surfaces, e.g. fingers. These may be separated relatively easily by soaking the bonded area in warm, soapy water for several minutes and then gently peeling the bond. Alternatively, a dull instrument such as a thin wire or a table knife can be forced through the bond. With appropriate caution, solvents such as acetone or nail polish remover can be used effectively.

When skin contact is over a large area, the area should be flushed with large amounts of water. A soaking wet cloth can be used to wipe off excess adhesive. If the adhesive has soaked through clothing, flush the involved area with water. If the cloth has bonded to the skin, the removal of the bonded clothing without these precautions might result in skin damage. Cured adhesive will flake from the skin within a day or so or can be removed by treatment or by soaking with hot, soapy water.

ORAL CONTACT:    Cyanoacrylates are relatively non-toxic materials (Acute Oral LD50 >5000 mg/kg). However, rapid polymerization (hardening) of the adhesive will take place in contact with the surfaces of the mouth. The mouth should be flushed copiously with water and medical aid should be sought immediately. Lips, if bonded, can be gently peeled apart, preferably with the aid of hot water or solvent.

VAPOR EFFECTS:

EYES:   Alkyl cyanoacrylate vapors are lachrymatory (tear producing) and can cause eye irritation and tearing in poorly ventilated areas.

MUCOUS MEMBRANES: Mucous surfaces can become irritated by prolonged exposure to cyanoacrylate vapors in poorly ventilated areas. Vapor irritation to the eyes and mucous membranes will be most noticeable under conditions of low relative humidity.

VAPOR CONTROL RECOMMENDATIONS:

* Use adequate ventilation. Remove adhesive vapors with suitable exhaust ducting. Since cyanoacrylate vapors are heavier than air, place exhaust intake below work area. Activated charcoal filters using an acidic charcoal have been found effective in removing vapors from effluent air.

* Avoid use of excess adhesive. Excess adhesive outside of bond area will increase level of vapors.

* Assemble parts as quickly as possible. Long open times will increase level of vapors.

VII. PRECAUTIONS FOR SAFE HANDLING AND USE:Health hazard rating is 2,  Slightly hazardous. Fire hazard is 2, Flash point above 100 ° F not exceeding 200. Reactivity rating is 1, Unstable if heated.

Provide adequate ventilation in area of usage. When possible this should be achieved by the use of local exhaust ventilation and good general ventilation. Vapors are heavier than air, therefore, downward ventilation should be used. When handling cyanoacrylate adhesives, goggles or safety glasses should always be worn. Polyethylene gloves should be used to protect the hands. CAUTION: Do not use rubber or cloth gloves. Rubber gloves will bond when brought in contact with the adhesive and porous cotton gloves will absorb the adhesive and bond the gloves to the skin.

Store in original container below 40° F for prolonged shelf life.

In the event of small spills, material may be wiped up with a soaking wet cloth and the area cleaned with solvent. When large quantities of cyanoacrylate adhesive are accidentally spilled, the area should be flooded with water which will cause the liquid cyanoacrylate to cure. The cured material can then be scraped from the surface. It may then be incinerated observing all State, Federal and local anti-pollution and waste disposal regulations.

VIII. CONTROL MEASURES:Transport: This product is not regulated for shipping purposes.

Other: Respiratory protection is not normally necessary unless product is used in enclosed area of poor ventilation or individual has a history of chronic respiratory disease. Local exhaust is

recommended. Protective gloves are recommended during use (See section VII above). Always wash hands thoroughly after use.
