Question

ПОМОГИТЕ ПОЖАЛУЙСТАААА !!! При скорости самолета 900км/ч его четре двигателя развивают полезную мощность 30 МВт. Найдите силу тяги каждого двигателя в этом режиме полета.

Answer 1

V=250 м/с    P=30*10^6 Вт   n=4    F=?
===
P=n*F*v
F=P/(n*v)=30*10^6/(4*250)=30*10^3 H    (30 кН)
====================================

Answer 2

P=A/t
A=F×s
P=F×s/t=F×V
900км/час=250м/с
F=P/V=3×10^7/250=12×10^4Н=120кН

Answer 3

Calculating Thrust Force of Each Engine

To calculate the thrust force of each engine in this flight regime, we can use the formula:

Thrust force = Power / Velocity

Given: - Speed of the airplane (V) = 900 km/h = 900,000 m/h - Useful power of the four engines (P) = 30 MW = 30,000,000 W

Using the formula, we can calculate the thrust force of each engine:

Thrust force of each engine = Power / Velocity

Thrust force of each engine = 30,000,000 W / 900,000 m/h

Thrust force of each engine ≈ 33.33 N

Therefore, the thrust force of each engine in this flight regime is approximately 33.33 Newtons.
