航空和航天技术的发展历史证明,不论是空军和民航的各类飞机,还是巡航导弹的发展,都同发动机类型和性能的不断改进密切相关.所以,我们为了正确判断发展方向,采取恰当的发展方针,随时了解和正确判断国外发展动向,是十分必要的.本文主要是对涡轮喷气发动机的发展方向及一些国外弹用小型涡轮喷气发动机和涡轮风扇发动机发展情况作一简要的介绍. The history of aviation and space technology has proven that both the Air Force and civil aviation aircraft and the development of cruise missiles are closely related to the continuous improvement of engine type and performance so that in order to correctly judge the direction of development and adopt proper development Policy, keep abreast of and correctly judge the development trend of foreign countries, is very necessary.This paper is mainly on the development of turbojet engine and some foreign small turbojet engine and turbofan engine development situation made a brief introduction.
