Consider an airplane patterned after the Fairchild Republic A-10, a twin-jet attack aircraft. The airplane has the following characteristics: wing area = 47 m2, aspect ratio = 6.5, Oswald efficiency factor = 0.87, weight = 103,047 N, and zero-lift drag coefficient = 0.032. The airplane is equipped with two jet engines with 40,298 of static thrust each at sea level. The thrust-specific fuel consumption is 1.0 N of fuel per Newton of thrust per hour. The fuel capacity is 2800 gal, and the maximum gross weight is 136,960 N. Calculate the range and endurance at a standard altitude of 8 km, where ?? = 0.526 kg/m3.

Condor Airplane Company has built a new model jet aircraft which it intends to sell to high net worth clients. This aircraft required 25,000 hours to complete. Condor believes an incremental unit-time learning model with an 82% learning curve best reflects the company's production efficiency. Condor just received a contract to make fifteen identical aircraft. What will be the expected unit time for the sixteenth aircraft?

A twin-blade aircraft propeller has a mass of 30.0 kg and a radius of 1.50 m. When the aircraft is flying at its top speed of 162 knots the tips of the propeller blades may not move faster than 300 m/s through the air (otherwise they would be travelling supersonically). Determine: 3.1 the maximum safe angular speed of the propeller in rpm; 3.2 the torque the engine must exert on the propeller in order for it to reach this maximum...
