Question Paper
Using Kutta-Joukowski theorem, explain the expression for lift in terms of circulation.
Discuss lift on rotating cylinder in uniform
flow.
How does Van der Waal's equation differ from ideal gas equation? Explain.
Draw the pitching moment curve for supersonic profiles. How do pitching moment and centre of pressure vary with angle of attack for a supersonic profile?
3. Derive the expression for the induced angle of attack considering an elliptical lift distribution.
4. What are wind tunnels? Explain the difference between subsonic and supersonic wind tunnels, using neat sketches.
The weight of an aircraft is 50,000 kg and the drag produced is 5,000 N in cruise flight. Calculate the lift and drag coefficients in cruise, if the aircraft moves at a velocity of 1000 km/hr. Assume sea level conditions and planform area 90 m^2 .
Briefly explain the terms convective and local acceleration in fluid flow.
Distinguish between the following:
Uniform and Non-Uniform Flow
Steady and Unsteady Flow
Rotational and Irrotational Flow
How are streamlines and equipotential lines related to each other?
7. Derive the general Navier-Stokes equation for an unsteady, incompressible and viscous flow.
8. Define the following terms
Ideal Fluid
Incompressibility
Circulation
Reynolds Number
Turbulence
9. Write short notes on any two of the following:
Supercritical Airfoil
Magnus Effect
Doublet Flow
Aircraft Flaps
