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 first jet aircraft flight?Heinkel He 178, Germany, August 27, 1939
2. What is the modern engine type?Turbofan engines are prevalent in modern airliners for efficiency and reduced noise
3. How does a jet engine create thrust?A jet engine compresses air, mixes it with fuel, burns it, and then pushes the hot gas out the back at high speed. This pushes the plane forward.
4. When did the first jet aircraft fly?The first jet aircraft, the Gloster E.28/39, flew in 1941 after a turbojet engine was tested in 1937. Another early jet, the Heinkel He 178, flew in 1939.

Turbojet Engine: An early type of jet engine that uses a turbine to drive a compressor, expelling hot gas for thrust.
Turbofan Engine: A more efficient jet engine that uses a large fan to bypass some air around the core, increasing thrust and fuel economy.
Aerodynamics: The study of how air moves around solid objects, crucial for aircraft design.
Brayton Cycle: The thermodynamic cycle that describes the functioning of a constant-pressure heat engine, like a jet engine.
