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 propulsion system type?Altitude-compensating rocket engine
2. What is the key technological advantage?Maintains high propulsive efficiency across a wide range of atmospheric densities
3. How does an aerospike engine work at different altitudes?At sea level, the air presses the gases against the spike, forming a gas skirt that keeps the thrust strong. As the rocket climbs and the air thins, the gases can expand more freely, but the spike still guides them, so the engine stays efficient.
4. Why is the aerospike engine better than a regular rocket nozzle?Because it can stay efficient at many different pressures, it uses less fuel and can carry more cargo or reach higher speeds. It also has a simpler shape than some other engines.

Annular Combustion Chamber: A ring-shaped chamber where propellants are mixed and burned to produce hot gases.
Gas Dynamics: The study of how gases move and interact, especially at high speeds and pressures.
Thrust Vectoring: The ability to control the direction of a rocket's thrust for steering and stability.
