Consider a finite wing with an aspect ratio of 5. Assume an elliptical lift distribution. The lift slope for the airfoil section is 0.1/degree. Identify the correct statement about the lift slopes for the straight wing and the swept wing with a half-chord line sweep of 45 degrees. Multiple Choice A swept wing with a half-chord line sweep of 45 degrees has a slightly more lift slope than a straight wing. A swept wing with a half-chord line sweep of 45 degrees has a substantially more lift slope than a straight wing. A swept wing with a half-chord line sweep of 45 degrees has a slightly less lift slope than a straight wing. A swept wing with a half-chord line sweep of 45 degrees has a substantially less lift slope than a straight wing.

Consider a NACA 24016 wing with an aspect ratio of 8. The span efficiency factor is e = 0.79. If the wing is at a 7° angle of attack, calculate C L and CD . For the infinite wing at α = 11° the Cl = 1.4, at α = 0° the Cl = 0.1, α = −1.4° the Cl = 0 and cd = 0.006.
- Study how the lift and drag varies with a change in angle of attack for a flat plate, symmetrical airfoil and asymmetrical airfoil when Re is below 50'000 and compare it to higher Re.
Explain the following: i. The pressure altitude of an aircraft is usually different from the temperature altitude. ii. Flow separation over an airfoil occurs at high angle of attack. iii. Lift coefficient of a wing is less than lift coefficient of the airfoil that makes up that wing. iv. High lift devices are needed during takeoff and landing.

An aircraft is required to climb with 10° of climb angle. The aircraft has a mass of 30,000 kg and produces 50,000 N of drag. Assume zero angle of attack and zero thrust setting angle. How much thrust the aircraft engine must produce?
A rotating cylinder generates lift through the Magnus effect. Derive an expression for the lift coefficient of this force (relative to the cross sectional area of the cylinder) that depends on the angular velocity w, radius R, and upstream velocity Uo.
Choose the most appropriate statement with respect to the pressure distribution of an airfoil. The flow velocities go to zero at the leading and trailing edge points. Upper and lower surface pressures are lower than under free-stream conditions. Upper and lower surface pressures are higher than under free-stream conditions. O Lift is the difference between the lower and upper surface pressures.
