At a flight speed of 800 km / h, all four aircraft engines develop a power of 30 MW. Find the thrust of four engines in this mode.

The thrust force of the four aircraft engines during flight is expressed and calculated from the power formula:

N = F * V, where N is the power of four aircraft engines (N = 30 MW = 30 * 10 ^ 6 W), F is the required thrust force of the engines (N), V is the aircraft flight speed (V = 900 km / h = 900 * 1000/3600 m / s = 250 m / s).

F = N / V.

Let’s do the calculation:

F = 30 * 10 ^ 6/250 = 120,000 N = 120 kN.

Answer: The thrust force of four aircraft engines during flight is 120 kN.
