Question
A jet airplane weighs 160,000 N and has a zero-lift drag coefficient of 0.008 and a wing area of 42 m^2. At 100 m/s at sea level, the rate of climb is 11.5 m/s. The thrust developed by the engines is equal to 27,000 N. Determine the maximum rate of climb and the corresponding flight speed at sea level .

- The drag polar for the ASW 27B high performance sailplane is: CD = 0.01 +0.02CL2. What is its maximum lift-to-drag (L/D) ratio? 18 25 35 70arrow_forwardand power for part barrow_forwardA propeller-driven aircraft has an in-flight weight of 4,105 lb (equivalent to a mass of 1,862 kg) and is cruising at a true airspeed of 120 kts. The lift-to-drag ratio of the aircraft is 8.2. If the propeller efficiency, ηp, is 0.8, then how much brake power is required for flight? Work through this problem in both USC and SI units.arrow_forward
- An aircraft has a total mass of (1.26x10^2) kg and a wing area of (3.000x10^1) m2. It operated with an aerofoil section having CL = 1.0 and CD=0.1. Assuming that the total drag of the wing represents the whole drag of the aircraft, find the power input required for to overcome gravity and take off. Assume density of air to be 1.2 kg/m3. Answer should be in Watts with three significant figures.arrow_forward2.4 A 2650-lb car is traveling at sea level at a constant speed.
