Question

The Harrier Jet is a fixed wing jet designed for vertical takeoff and landing. It is capable of rotating its jets from a horizontal to a vertical orientation in order to takeoff, land and conduct horizontal maneuvers. Determine the vertical thrust required to accelerate a 19000 lb Harrier upward at 1.3 ft/s2.

Answer 1

force required to have that upward acceleration

F = m ( a + g)

F = 19000* ( 1.3 + 32 2)

F = 636500 lb ft /s^2
