Combustion,haust gas. Some engines have a second combustion system which either reheats the flow for the later turbine stages (section 3.6.2), or burns more fuel in an afterburner behind the turbines to provide the high exhaust velocity required for the propulsion of supersonic aircraft (section C.6).作者: Barter 時(shí)間: 2025-3-22 13:38 作者: Barter 時(shí)間: 2025-3-22 20:06

It absorbs energy from an external power source, raising the pressure of a continuous flow of working fluid by means of its blading geometry and motion.作者: 陶瓷 時(shí)間: 2025-3-24 22:47
Schlichtungswesen und Arbeitskampf,The potentially tricky operation of dynamic compressors, with their propensity to surge, has already been mentioned in section 1.3 and chapters 5 and 6. It is a big enough subject to merit its own chapter, before the way in which the compressor is matched to the turbine and the over-all engine operating characteristics are discussed in chapter 11.作者: 創(chuàng)新 時(shí)間: 2025-3-25 01:48 作者: 言行自由 時(shí)間: 2025-3-25 04:38 作者: Pillory 時(shí)間: 2025-3-25 10:21

Applications for Gas Turbine Engines,Gas turbine engines are most generally known for their use in aircraft (section 2.1)[9] but they are also used in surface transportation (section 2.2) and increasingly in stationary applications. The latter field encompasses the greatest variety of configurations and purposes and is still expanding, whereas the aviation field is consolidating.作者: homeostasis 時(shí)間: 2025-3-25 23:53 作者: 帳單 時(shí)間: 2025-3-26 00:24 作者: 織物 時(shí)間: 2025-3-26 08:20
Gas Turbine Engine Control,The performance parameters of a running gas turbine are determined at any time by a unique set of curves, such as those in figure 4.2. Of all the parameters shown, it is the fuel flow which is the input and which controls the operation.作者: Limpid 時(shí)間: 2025-3-26 11:36
