Question

If the aircraft has a power-producing engine which have driven propellers then the power is to be converted to thrust to formulate the equations of motion.

(a) True

(b) False

This question was posed to me in unit test.

The origin of the question is Equations of Motion for Performance in division Aircraft Force Systems and the Equations of Motion of Aircraft Performance

Answer 1

Correct choice is (a) True

Best explanation: If the aircraft has a power-producing engine which have driven propellers then the power is to be converted to thrust to formulate the equations of motion. The conversion is given as FN=ṁ(Vi-V) where FN is net thrust force, ṁ is mass flow rate and Vi, V are velocities.
