Jet engine - Wikipedia
网页A jet engine is a type of reaction engine, discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition may include rocket, water jet, and hybrid propulsion, the term jet engine typically refers to an internal combustion air-breathing jet engine such as a turbojet, turbofan ...
Jet engine | Design, Types, & Functionality | Britannica
网页2024年9月6日 · The prime mover of virtually all jet engines is a gas turbine. Variously called the core, gas producer, gasifier, or gas generator, the gas turbine converts the energy derived from the combustion of a liquid hydrocarbon fuel to mechanical energy in the form of a high-pressure, high-temperature airstream.
How do jet engines work? | Types of jet engine compared
网页2021年12月11日 · A jet engine works by burning fuel in air to release hot exhaust gas. But where a car engine uses the explosions of exhaust to push its pistons, a jet engine forces the gas past the blades of a windmill-like spinning wheel (a turbine), making it rotate. So, in a jet engine, exhaust gas powers a turbine—hence the name gas turbine. Action and ...

网页2012年2月14日 · Jet engines create forward thrust by taking in a large amount of air and discharging it as a high-speed jet of gas. The way they’re designed allows aircraft to fly faster and further compared to propeller-driven aircraft.
Jet Engine Design: The Turbine - Aerospace Engineering Blog
网页2013年4月6日 · The turbine is at the heart of any jet engine with its primary task being to drive the compressor. As described previously without the compressor no mechanical work would be done on the fluid prior combustion and the thrust produced would only be a function of the chemical energy stored within the fuel.

网页2024年4月16日 · For a gas turbine engine, the accelerated gas, or working fluid, is the jet exhaust. Most of the mass of the jet exhaust comes from the surrounding atmosphere. Most modern, high-speed passenger and military aircraft are powered by gas turbine engines.
How Jet Engines Work - YouTube
网页An inside look at how jet engines work. Most modern jet propelled airplanes use a turbofan design, where incoming air is divided between a large fan and the ...
How does a jet engine work? - Popular Science
网页2023年3月22日 · A jet engine is a highly complex piece of equipment with a straightforward job: to give an airplane the thrust it needs to fly. Anyone who has felt themselves pushed back slightly in their seat...
How Does a Jet Engine Work? - Pilot Institute
网页2023年7月17日 · A gas turbine jet engine works by compressing air, mixing it with fuel, igniting the mixture, and ejecting the air behind the engine, creating a pushing force known as thrust. The engine does this using the basic principle of intake, compression, combustion, and exhaust, known as the Brayton cycle.
How Do Jet Engines Work? - Simple Flying
网页2024年7月5日 · Jet engines are complex machines that have revolutionized the aviation industry with their sheer size, aerodynamic structure, and fuel efficiency. Modern jet engines are manufactured with composite materials and advanced manufacturing techniques to minimize weight and achieve fuel savings for operators.
