At a flight speed of 900 km / h, all four engines of the Il-62 aircraft develop a power of 30 mW.

At a flight speed of 900 km / h, all four engines of the Il-62 aircraft develop a power of 30 mW. Find the thrust force of one engine in this operating mode.

Given:
v = 900 km / h = 250 m / s – the speed of the IL-62 aircraft engine;
n = 4 is the number of engines installed on the aircraft;
W = 30 MW = 3 * 10 ^ 7 Watt – the power that the aircraft engines develop.
It is required to determine F (Newton) – the thrust force of one engine.
Let’s find the traction force developed by 4 engines:
F1 = N / v = 3 * 10 ^ 7/250 = 120,000 Newtons.
Then one engine develops a thrust force:
F = F1 / n = 120,000 / 4 = 30,000 Newtons.
Answer: the thrust force of one engine of the IL-64 aircraft is 30,000 Newtons.
