| **At a flight speed of 900 km / h, 4 aircraft engines develop a power of 30 MW. Find the thrust of one engine in this mode.**

V = 900 km / h = 250 m / s.

n = 4.

N = 30 MW = 30 * 10 ^ 6 W.

F1 -?

The power of the aircraft N is determined by the formula: N = F * V, where F is the thrust force of the aircraft, V is the speed of the aircraft.

Since the aircraft has n engines, the aircraft thrust force F will be determined by the formula: F = n * F1, where F1 is the thrust force of one engine.

N = n * F1 * V.

F1 = N / n * V.

F1 = 30 * 10 ^ 6 W / 4 * 250 m / s = 30,000 N.

Answer: the thrust force of one engine is F1 = 30,000 N.
