A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage.

The Pratt & Whitney PW1000G family, also marketed as the Pratt & Whitney GTF (geared turbofan), is a family of high-bypass geared turbofan engines produced by Pratt & Whitney.

Motor Sich inherited some of the former Soviet Union's aero engine manufacturing capabilities. It produces turbofan, turboprop and rotary-wing turboshaft engines that power aircraft in Russian service, such as Mi- and Ka-series military helicopters.

2021年5月13日 · Most modern airliners use turbofan engines because of their high thrust and good fuel efficiency. On this page, we will discuss some of the fundamentals of turbofan engines. A turbofan engine is the most modern variation of the basic gas turbine engine.

Turbofan engines are one of the most popular propulsion systems used in commercial aircraft due to their high thrust and good fuel efficiency. To reduce noise generated from turbofan engines-powered aircraft, a number of control approaches have been developed.

2024年6月26日 · Figure 6.14: Turbofan. There are two types of turbofans: high bypass and low bypass, as illustrated in Figure 6.14. High bypass turbofans have large fans in front of the engine and are driven by a fan turbine located behind the primary turbine that …

turbofan (plural turbofans) ( aviation ) A turbojet engine having a (typically ducted) fan that forces air directly into the hot exhaust and obtains a portion of the thrust from the turbojet and a portion from the turbojet section.

The geared turbofan is a type of turbofan aircraft engine with a planetary gearbox between the low pressure compressor / turbine and the fan, enabling each to spin at its optimum speed. The benefit of the design is lower fuel consumption and much quieter operation.

A turbofan engine is basically a turbojet to which a fan has been added. Large fans can be placed at either the front or rear of the engine to create high bypass ratios for subsonic flight. In the case of a front fan, the fan is driven by a second turbine, located behind the primary turbine that drives the main compressor.
