O jectives o t isworkshop

In a Bachelor Engineering course students are mainlyinvolved in theoretical aspects of aircraft design and

its elements. But realization of an real aircraft

involves various phases . As a student it would be

ambitious to realize the full size aircraft of any

aviation category. Hence it would be more

appropriate to design an aircraft which is of a

realizable size. UAVs of smaller size would perfectly

suit this need. Hence the work shop deals with the

design, fabrication and field testing of an small sized

UAV.


5/17

How this is useful for the students?

Realization of an aircraft involves all the aspectsof Aeronautical Engineering. The students willhave a chance to match their theoreticalknowledge to the practical aspects of designing

and realizing the product which is of criticalimportance

In a real industry environment , it is required towork on the design and analysis of real aircrafts.

Once they are clear with the whole process ofdesign they would able to understand andperform better in their organizations.

Who will be the Trainers & Instructors??

Young & Dynamic Aerospace Engineers working in the Industry from

several years on variety of aircraft design projects

Design Engineers who in the past have worked on the Indiasambitious aircraft design projects (MAVs, UAVs, SARAS, NM5 etc..)at various organizations like IITs, NAL, ADA etc..

In the present working as Consultants, Project leaders for variousAIRBUS design projects & with major European Suppliers for aircraftmanufacturing companies worldwide

Having an experience in the aerospace industry of over 5-7 yrs

Manufacturing and hangar training will be provided by experiencedAircraft Maintenance Engineers (over 10-15 yrs of experience)

F// Design Methodology

1. Ground up approach Learn all the basics, then design your vehicle

around your mission requirements

AerodynamicsPropulsionStructurePerformanceStability and Controletc.

2. Empirical approach

Use essential data from previously designed

aircraft in particular category to determine thebaseline, then worry about the details

Weightwing sizeengine sizeetc.


12/17

F// Design Methodology

Empirical design method (One of the many ways) Estimate weight (TOW or Wo) based on known payload

Estimate wing size based on known speed and liftcoefficient

Select wing shape and aspect ratio based on type ofaircraft

Select C.G. location based on static margin requirements(Stability) as given distance from a.c

Select wing twist, if any

Size control surfaces based upon tail distance from C.G Iterate

Need baseline data

UAVs vs Convn. AC

What makes UAV design different fromtraditional aircraft design

They both are designed around payloads, but.

. .


14/17

The problem

Low speed, small size

High Altitude

Low density UAVs Re = 10^510^6

MAVs Re = 10^410^5

Viscous forces are significant- separationprevalent : low L high Dlow L/D

Outside of Classical Aerodynamic Design
