With an increase In aspect ratio of a wing the the value of

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

Solution

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
