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.

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.

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

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

What makes UAV design different fromtraditional aircraft design
They both are designed around payloads, but.

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
