Explain the concept of thrust in gas turbine engines.

• A. It is the force that cools the engine
• B. It is the backward pressure created during combustion
• C. It is the forward force produced due to the acceleration of exhaust gases
• D. It is the energy produced by the compressor

Answer: (C)

Thrust in gas turbine engines is fundamentally the forward force generated as a result of accelerating exhaust gases. When fuel is burned in the combustion chamber, it produces high-temperature, high-pressure gases. These gases expand rapidly and exit the engine through the exhaust nozzle at a significant speed. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. As the gases are expelled backward, the engine experiences a forward thrust. This principle is crucial for the operational effectiveness of aircraft, as it propels them forward through the air. The concept of thrust is essential to the performance and efficiency of a gas turbine engine, determining how effectively it can move an aircraft or a vehicle. Understanding this fundamental mechanism allows engineers to optimize engine design for better performance and fuel efficiency.
