jet engine n. 1.An engine that develops thrust by ejecting a jet, especially a jet of gaseous combustion products. 2.An engine that obtains the oxygen needed from the atmosphere, used especially to propel aircraft and distinguished from rocket engines having self-contained fuel-oxidizer systems....
A jet engine for propelling aircraft, capable of providing thrust from rest to high speeds. Characterised in that it employs a liquid oxidant and two liquid fuels of different molecular weights. The engine has an axial compressor (16) or several axial compressors located on the same plane, but...
供以动力,驱动【解析】根据题目可知,句子的主语为“aircraft(飞机)”,而谓语为被动态,“a jet engine(喷气发动机)”则是“power”这个动作的执行者。根据常识,发动机是能够提供动力的机器。故可以推断这里的power应当是“供以动力,驱动”的含义。因此本句可翻译为“这架飞机由喷气发动机驱动”。
The jet engine (1) has an inlet region (3), a secondary flow channel (2) and an engine core (5). An intermediate housing (15) is partially arranged between the secondary flow channel and engine core. A tank device (19) made of aluminum sheet or composite material is integrated in the...

an engine with a centrifugal compressor tends to be wider (greater cross-sectional area) than a corresponding axial. This creates additional undesirable aircraft drag. Centrifugal compressors are also less efficient than axial compressors. For all of these reasons, most high compression jet engines use...
