Data: N (engine power of the aircraft used) = 735 kW = 735 * 10 ^ 3 W; V (modulus of speed) = 252 km / h (in SI system V = 70 m / s).
To determine the sought modulus of the aircraft thrust force, we use the formula: N = F * V and F = N / V.
Calculation: F = 735 * 10 ^ 3/70 = 10.5 * 10 ^ 3 N (10.5 kN).
Answer: the module of thrust of the aircraft used is 10500 N.
