Question

List four factors that affect the amount of thrust produced by a gas turbine engine.

Answer 1

The amount of thrust produced by a gas turbine engine is primarily affected by the exhaust velocity, the rate of mass ejection, the mass of the engine itself, and the efficiency of the combustion process.

Step-by-step explanation:

The amount of thrust produced by a gas turbine engine is influenced by several factors. Here are four key factors:

1. The exhaust velocity of the gases relative to the engine - The greater the exhaust velocity (Ve), the more thrust is generated.
2. The rate at which mass is ejected from the engine - Represented by (Am/At), a higher mass flow rate contributes to greater thrust.
3. Mass of the rocket or engine itself - A lighter engine, all else being equal, would result in greater acceleration and thereby more effective thrust over time.
4. The combustion process quality and efficiency within the engine - Efficient combustion will maximize the thrust produced from the consumed fuel.

These factors are essential in understanding how a rocket or aircraft using a gas turbine engine can optimize its performance to achieve the desired acceleration and speed.
