Nov / Dec 2013 Important Questions
1. Types of drags and its reduction methods.
2. ISA layers, Troposphere, stratosphere derivation.
3. Obtain the values of pressure, density and temperature at 5 km in ISA.
For unit-II may three types of questions will ask in your university exams.
1.Derive the two equations given below and represent it graphically
2. An airplane is flying straight and level at a speed V which is ‘n’ timer the minimum power speed Vmp. Show that
3. For an aircraft in straight and level flight at a speed of ‘M’ derive the minimum drag speed. Show that
where D is drag of the aircraft.
4. An aircraft weighing 25 kN has a wing area of 80 m^2 and its drag coefficient is
calculate the minimum thrust required for straight and level flight, and the corresponding true air speed. At sea level and at 10 km (ρ= 0.58kg/m^3). Calculate also the minimum power required and the Corresponding true air speeds at the above conditions.
5.Drag polar for different speeds.
1. V-n diagram.(Refer Aircraft performance book, pages 341-343)
2. Maneuvering, climbing, Gliding, and Turning flight performance.
1. Range and Endurance equations.(Refer class notes)
2. Power available and power required curves.(Refer class notes)
1. Wing contribution and wing with tail contribution derivations.
2. Problems taken w.r.t above derivations.
