Calculate Jet Engine Thrust for 800 kg Jet Takeoff with 4 m/s^-2 Acceleration

In summary, calculating jet engine thrust involves using the formula T = m x a, where T is the thrust, m is the mass of the jet aircraft, and a is the acceleration. The units for thrust are typically measured in Newtons (N) or pounds (lb). The mass of a jet aircraft can be determined by adding the dry weight to the weight of fuel and cargo on board. The acceleration used for takeoff can range from 3-5 m/s^2, and jet engine thrust can greatly impact takeoff performance by allowing for faster acceleration and shorter required runway length.

Homework Statement


Calculate the engine thrust required to produce an acceleration of 4 m/s^-2 in a jet of mass 800 kg as it takes off along the runway. The air resistance is 500 N
Appreciate if anyone can check if I have used the correct equation, and my answer.

Homework Equations


F - R = ma


The Attempt at a Solution


F - R = 800 x 4
F - 500 = 3200
Thrust (F) = 3700 N

Related to Calculate Jet Engine Thrust for 800 kg Jet Takeoff with 4 m/s^-2 Acceleration

1. How do you calculate jet engine thrust?

The formula for calculating jet engine thrust is T = m x a, where T is the thrust, m is the mass of the jet aircraft, and a is the acceleration.

2. What are the units for jet engine thrust?

The units for jet engine thrust are typically measured in Newtons (N) or pounds (lb) in the English system.

3. How do you determine the mass of a jet aircraft?

The mass of a jet aircraft can be determined by adding the weight of the empty aircraft (known as the dry weight) to the weight of the fuel and cargo on board.

4. What is the acceleration typically used for jet takeoff?

The acceleration used for jet takeoff can range from 3-5 m/s^2, depending on the size and type of the aircraft.

5. How does jet engine thrust affect takeoff performance?

Jet engine thrust plays a crucial role in determining the takeoff performance of a jet aircraft. A higher thrust allows the aircraft to accelerate faster and reach takeoff speed more quickly, reducing the required runway length and improving overall performance.
