Gas turbine - Wikipedia
Airbreathing jet engines are gas turbines optimized to produce thrust from the exhaust gases, or from ducted fans connected to the gas turbines. [40] Jet engines that produce thrust from the direct impulse of exhaust gases are often called turbojets .

2021年5月13日 — Jet engines move the airplane forward with a great force that is produced by a tremendous thrust and causes the plane to fly very fast. All jet engines, which are also called gas turbines, work on the same principle. The engine sucks air in at the front with a fan.
Jet Engine Design: The Turbine - Aerospace Engineering Blog
2013年4月6日 — The gas turbine produces higher specific power and thus efficiency as the turbine entry temperature (TET) of the gas exiting the combustion chamber is increased. Of course the TET is bounded by the metallurgy of the turbine blade materials.
How Gas Turbine Engines Work - HowStuffWorks
In all modern gas turbine engines, the engine produces its own pressurized gas, and it does this by burning something like propane, natural gas, kerosene or jet fuel. The heat that comes from burning the fuel expands air, and the high-speed rush of this hot air spins the turbine.

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.

2024年4月16日 — We sometimes call this engine a jet engine. Early gas turbine engines worked much like a rocket engine creating a hot exhaust gas which was passed through a nozzle to produce thrust. But unlike the rocket engine which must carry its oxygen for combustion, the turbine engine gets its oxygen from the surrounding air. A turbine engine does not ...
How Does a Jet Engine Work? - Pilot Institute
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.

2024年11月23日 — In a jet engine the turbine is designed to provide just enough output to drive the compressor and auxiliary devices. The stream of gas then leaves the turbine at an intermediate pressure (above local atmospheric pressure) and is fed through a nozzle to produce thrust.

5 天之前 — 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 does a jet engine work? Brayton thermodynamic cycle and ...
2019年8月22日 — The operation of a jet engine is represented by the Brayton cycle, a thermodynamic cycle that underlies all gas turbine engines. The Brayton cycle illustrates the thermodynamic processes occurring in an engine, describing how heat and energy are managed by the engine to generate work, which in the case of a jet engine is propulsive thrust.
