Identify the appropriate lift-to-drag ratio if an aircraft requires 1 500 kN of lift with an attendant drag of 100 kN.

Back

15 : 1

Front

For the aircraft illustrated, maintaining constant speed and level flight, calculate the drag and lift if the weight is 2.5 tonnes and the thrust is 45 kN.

Back

Drag = 45 kN, Lift = 25 kN

In a hydraulic system, fluid is supplied under pressure to a mechanism transferring this force into mechanical movement by means of a: ram, wing flap, servo motor, linear actuator
