Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the thermodynamic cycle?Primarily operates on the Brayton cycle
2. What is the key performance indicators?Turbine inlet temperature, pressure ratio, and thermal efficiency
3. What is a gas turbine and how does it work?A gas turbine is like a giant fan that powers airplanes and homes. It compresses air, mixes it with fuel, burns it, and lets the hot gas spin a turbine that turns the compressor and sometimes a fan or generator.
4. Why do gas turbines need special materials?The gas gets very hot, so the turbine blades must be made from strong, heat‑tolerant alloys and cooled with special techniques to keep them from melting.

Brayton Cycle: A thermodynamic cycle describing the operation of gas turbines, involving compression, heat addition, and expansion.
Turbofan Engine: A type of jet engine that uses a large fan to bypass much of the air around the engine core, increasing efficiency.
Combined Cycle Power Plant (CCGT): A power plant that uses both a gas turbine and a steam turbine to generate electricity, achieving higher overall efficiency.
