弹用涡扇发动机的特点及其发展动向

FEATURES AND DEVELOPING TRENDS OF TURBOFAN ENGINES FOR MISSILES

远程巡航导弹均用涡扇发动机作为主发动机.这种弹用涡扇发动机与普通航空涡扇发动机相比具有许多不同的特点.其基本特征是小体积、小推力、低成本和短寿命.本文讨论了这种弹用涡扇发动机的设计准则、总体性能、结构、制造工艺及其发展动向.

Sustainers for long range cruise missile are always the turbofan engines. The features of the turbofan engines used in missiles are much differant from those for aeroplanes. The basic features of this kind of turbofan engines are low volume; small thrust, low cost and short life. The design criteria, overall performance, struture, manufacturing technology and developing trends of the turbofan e-ngines for missiles are discussed in this paper.
