Question

With an increase In aspect ratio of a wing the: the value of dC_L/alpha decreases the wing area increases at constant span the value of dC_L/da increases The wings of an aircraft provide. thrust and yaw of the aircraft drag and yaw of the aircraft lift and roll of the aircraft The drag polar: can represent a wing or entire aircraft is a parabolic equation relating the coefficients of lift and drag all of the above The turbulent boundary layer is: usually present at high Reynolds number flows avoided In favour of the laminar the alternative with lower drag both The purpose of the rudder of an aircraft Is: to provide stability in yaw to provide control of yaw to stabilize the aircraft in roll In a coordinated turn The lift component in the radial direction is balanced by centrifugal force The turn is executed without disturbing passengers' equilibrium All of the above A supercritical wing: Is usually applicable to transitional Mach flow conditions Is usually applicable to super

Explanation / Answer

7. (c) The wings of an aircraft provide Lift and roll of the aircraft

8. (C) represent both lift and it is a parabolic equation relating lift and drag.

9. (c) it has higher reynold number and with less drag compared to laminar

10. (b)  A rudder operates by redirecting the fluid past the hull (watercraft) or fuselage, thus imparting a turning or yawing motion to the craft.

12. (b) applicable to supersonic flowcondition
