搏击云天的歼击机靠着喷气发动机强大的推力在长空驰骋。喷气发动机由诸多部件组成,喷管(亦称尾喷管)既是产生推力的主要部件,也是半个多世纪来喷气发动机中发展最为迅速的部件。其占整台发动机的成本已由5%～8%猛增到30%。那么,喷管在喷气发动机上究竟扮演了什么重要“角色”呢?
Fighting sky fighter aircraft rely on jet powerful thrust in the sky to ride. The jet engine is made up of a number of components, the nozzle (also known as the tailpipe) is both a major thrust generating component and the most rapidly developing component of a jet engine for more than half a century. Its cost of the entire engine has soared from 5% to 8% to 30%. So what are the important “roles” of the nozzle on the jet engine?
