What does jet mean?

[VanSamantha]

Jet refers to a type of propulsion that utilizes the power of an engine. Additional information is as follows: 1. Engine: A jet engine is a reaction engine that generates thrust by expelling a jet of fluid. Most jet engines are internal combustion engines that operate based on Newton's third law. Broadly speaking, jet engines include rocket engines and air-breathing jet engines. Rocket engines carry both fuel and oxidizer onboard the aircraft, including solid-fuel rocket engines and liquid-fuel rocket engines, characterized by their ability to operate outside the Earth's atmosphere. Air-breathing jet engines, on the other hand, do not carry oxidizer but instead draw air from the atmosphere as oxidizer, including ramjet engines, pulsejet engines, turbojet engines, and turbofan engines. The most commonly used air-breathing jet engine in modern aviation transport aircraft is the turbofan engine, known for its high thrust, low noise, and low fuel consumption rate. 2. Propulsion method: Different types of jet engines, whether ramjet, pulsejet, gas turbine, turbo/ramjet, or turbo-rocket, differ only in the "thrust provider," i.e., the way the engine supplies energy and converts it into flight power.
