INTRODUCTION:

We are here to present the present

situation and a solution for existing air-forcetechnology. At present the pilot who is taking

control over a flight has to control the drive aswell as the weapon select and launching

simultaneously at the war-front. During whenthe enemies are attacking, the pilot has toprecisely come to a decision to turn a flight to

any side, or up or down in few microseconds.Thus for the lifes survival the time given is

only very few milliseconds. If the pilot isgoing to decide wrongly then his or her life

would be at risk.

So here we are going to suggest an

alternate method for this critical situation. Weare here going to automate the driving process

and also we use swarm robot technology to

avoid unnecessary nearing or collision of

flights during the pilots launching a weapon.Also here we are using GPS to find theshortest route to the destination due to which

the enemies may have a very less time to traceand hit back the air-force. In this first we are

going to get the map from the satellites andtrace the shortest route to the destination with

much less or no obstacles.

To discuss this paper in detail lets

first start with the swarm robot technology and

the GPS. The swarm robot technology is thetechnology by which two or more machines

communicate with each other and finish their

part of the job efficiently using this technologystandard formation can be made for easytargeting and launching. Also at emergency a

flight can be carried by another at some system

failures.

The third technology we are using is theautomated anti-locked on missile when the

flight is being locked on by the enemies. Inthis we are using ultrasonic spectrum to

determine whether any missile or enemy flight

is chasing us behind, if it going to happen thenthe system itself is going to take preventivemeasures to protect itself from demolition.

The updates introduced for this system are

Semi-automatic drive for the vehicle, Standard alignment for clear and easy

targeting, Semi-automatic protection among the

vehicles, Automatic anti-missile when locked

on.

GLOBAL POSITIONING SYSTEM:

SEMI-AUTOMATIC DRIVE FOR THE

PLANE:

In this, as usual the pilot drives the

flight to the destination that is the enemy zone.

During this time the control is under the pilot.

But when he nears the enemy zone, the pilotcan give up the control to the system which isloaded with the route map. The map can be

modified at any time by the pilot. Thus theflight is controlled by the pilot at first and

when the flight nears the enemy zone thecontrol is automated. Global Positioning

System (GPS) can be used to implement this.

GPS NETWORK:

There are 24 GPS satellites orbiting

around the world in which 21 are operatingand the three are space satellites which

operates when any of the 21 satellites are in

problem. These three satellites can be moved

to any position and hence can replace any ofthe 21 satellites. The GPS determines thelocation by calculating the difference between

the time that the signal is sent and the signal

that is received. For this purpose the satellitecarries an atomic clock for calculating the

accurate time.

WORKING OF GPS:

The GPS allows the user to determinethe latitude, longitude and altitude todetermine exactly where he is. At any place in

the globe at least four satellites sends thesignals.

The three satellites, here in this case

the satellites A, B, and C is used to determine

the latitude and longitude. And the fourthsatellites D is needed to determine the altitude.

The receiver calculates the location byreceiving the signals coming from the foursatellites.

The aircraft carries the receiver andcalculates the position exactly where it is and

takes the route accordingly to the destinationwhen the controls is given up to the system.

Thus in this case economical fuel consumptionis also an added advantage since it takes the

shortest route.

SWARM TECHNOLOGY:

Swarm technology is the emerging

technology in the field of robotics. There aremany discrete units capable of working

independently communicates with each other

and do the job jointly. Since all the units are

capable of independent there is no master/slaveconcept. In the master/slave system if themaster malfunctions or breaks down then the

whole system fails. But in this system all units

are capable of taking the control itself whenthe any other unit fails.

Consider for simplicity three units

capable working independently are linkedusing swarm technology. They are able to

communicate with any system directly withoutany particular unit as medium.

ALIGNMENT FOR EASY TARGETING:

Similarly the aircrafts which areindependent can communicate with each other.

The different units are aligned so that it easeswork of pilot in targeting. Consider the

situation that the aircrafts are not aligned and

enemy aircraft is fronting, then the first rowaircrafts only can easily target the enemy, but

the aircrafts behind are not able to target sincethe ally aircraft is before.

But when it is aligned then any aircraft cantarget the enemy easily. Thus for this

automatic alignment swarm technology can beused.

SEMI-AUTOMATIC PROTECTION

AMONG THE AIRCRAFTS:

In robotics the swarm technology isused to join or assemble the independent units

to perform any specific task or to reach any

specific destination when units separately are

not able to do that. Consider the following thesituation as illustration.

*assembled to perform some action

*join to cross when separately cannot do

Similarly when sometimes anyaircraft unit is damaged by enemies the other

aircrafts can carry the damaged one. Thusboth the life as well as the aircraft can be saved

from the enemies. Consider the situation that

one of the aircrafts wings are fired and becomeunstable, when it is the enemy zone the aircraft

cannot be landed and hence both the life and

the aircraft would be lost.

As a preventive measure damaged

aircraft is carried to their zone both life as well

as the aircraft could be saved. As the proverb

says A PENNY SAVED IS A PENNY

GAINED if the damaged aircraft is carried to

safe zone the loss is minimized and hence

obviously it is gain to their side. Also thepilots life also is saved hence the fetch is

double.

When a fighter plane caught fire and

if there is more possibility to save the planeand pilots life then using swarm technology

first the fire is extinguished by the neighbourplane. Then a lock is made between the two

planes and carried to the safe zone. Since the

propeller did not catch fire there is no need togenerate more power to carry the damaged

plane.

When swarm technology is used thedamaged aircraft can be carried by the otherand thus both the life as well as the costly

aircraft can be saved. We could remember theincident that during the Kargil war one of our

air-marshal who ejected out from his damaged

fighter plane was killed as he landed in the

enemy zone.

Such incident would not happen with

swarm technology. In this system too theoperation is not completely automatic, the two

aircrafts joins when the two pilots permit the

action.

First the damaged plane sends asignal to its pilot requesting whether to

perform the joining process. If the pilot

permits then the damaged plane sends requestto the nearest plane. That plane asks for the

permission from the pilot and if the pilot

accepts then the two aircrafts joins

automatically. In case if the pilot of the savingplane does not accepts then the damaged plane

send the request to the next nearest plane.Thus by implementing the swarm technology

in this way both the pilot as well as the plane

with minor damage can be saved and reusedafter repair.

AUTOMATIC ANTI-MISSILE

LAUNCHING:

The next update is the automatic anti-missile or patriot missile launch when the

fighter plane is being locked by a guided

missile. The commonly used method for

locking an aircraft is heat sensing type. In thistype the heat liberated from the propeller of theaircraft is first sensed and the data is loaded in

the missile so that the missile blasts off the

propeller.

In this case the time taken for the

missile to blast the aircraft is only three to five

minutes, and hence the pilot has to takepreventive action within this minimum time or

else his/her life would be at risk.

Thus the anti-missile launch is

automated as the computers are faster than thehuman brain at such critical situation. For this

automation the sonar technology can be usedfor this purpose.

SONAR:

Ultrasonic waves are emitted at the

back of the aircraft. Transceivers emits

ultrasonic waves and receive the reflected thewaves and calculate the distance of the chaser.

By consecutive calculation and the timeinterval the velocity of the chasing missile ismanipulated and accordingly launches the

patriot missile locked to the chasing missile.Other alternate anti-missile technique can also

be used

.

In the above case the heat sensing

guided missile is launched locked to the

aircraft propeller. When it enters the region of

ultrasonic spread the transceivers sense the

arrival of locked on missile and first calculatesthe velocity and direction of the missile. Whenit is determined that the missile is chasing thatparticular aircraft then the system

automatically launches the patriot missile to

destroy the chasing missile. In this method,

aluminum dust is ejected from the propeller,thus the aluminum dust liberates the same

amount of heat as the propeller which makesthe chasing guided missile to fail, making

wrong decision among the heat liberated by

the aluminum dust and the propeller and hitssome other objects.

For the automatic system, afterrecognizing that a missile is chasing behind, to

launch a patriot missile it would take a fewmicroseconds. Thus the incident that the

aircraft is destroyed by the guided missile canbe greatly reduced.

ADVANTAGES:

1. In the un-manned aircraft thedestination is fixed at first itself andcannot be modified or changed later.But in this case the pilot can modify

the route, destination and map at any

time. Thus this system is very

flexible.

2. When an advanced un-mannedaircraft is considered, the pilot

controls the aircraft from the basethrough wireless. In this case the

complete communication is through

air medium. Hence there is possibilityfor hacking the system and take the

control the aircraft by the enemies.But in our method the drive though

automated during the time of enemy

attack the pilot can take the control atany time manually and hence no

possibility of hacking comes.3. When compared to the completely

automatic system, this semi-automatic

system is some what cheaper and also

very efficient and flexible and theseare added advantages.4. If any fighter plane goes unstable

another planes carries the victim

plane which is otherwise would havefall down in the enemy zone. Thus

both life lost as well as the aircraft is

saved, as we know that for

manufacturing a fighter plane itconsumes several millions of rupees.

FUTURE WORK:

In the near future it can also be

possible to assemble a number of fighterplanes while flying using swarm technology to

produce a giant aircraft with great power andcapabilities and cause a great damage toenemies and dismantle the giant craft into

smaller units for independent attacks aftergreat attack.

This may lead to robotic evolution at

the borders rather than human soldiers. It may

even lead to weapons sharing among thefighter planes in the air while flying. This

virtually increases the weapon carryingcapacity of the aircrafts. When the number of

fighter planes increases the weapon carrying

capacity also virtually increases.

CONCLUSION:

In this paper we have presented our

views to make the air-force more flexible,efficient and powerful. The application of

swarm technology in this field greatly

increases the incidence for the evolution of

giant flying robots by assembling number ofsmaller fighter planes in the air anddismantling into individuals when there is no

need for massive damage. Thus with same

fighter planes we can make very massivedamage and also a moderate damage. By

different patterns of assembling different

varieties of flying robots can be produced.
