turbo jet engine

Innovation in aviation has centered on the development of the jet engine for civil use, first in a turbo propeller form and later as a pure jet.

航空业的革新集中于民用航空喷气式发动机的研发，首先是涡轮螺旋桨发动机，后来是纯粹的喷气机。

It will be noted that the emphasis in this book is on the turbo-jet engine and that no special part deals with the propeller-turbine engine.

应该指出，强调在这本书是关于在涡轮喷气发动机，并没有特殊的部分涉及与螺旋桨涡轮发动机。

Due to high thrust the Piston jet Engine can be used where turbo-jets aren't practical.

由于大推力活塞式喷气发动机可以用在涡轮喷气机是不实际的。
