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

• BIGEYE
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.

F - R = ma

## The Attempt at a Solution

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

Yeah... That looks right.

Thanks for taking the time.

## 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.
