摘要/Abstract

摘要： 从不同的角度对超音通流风扇发动机进行了探讨，介绍了超音通流风扇（ＳＴＦＦ）的工作模式及超音通流风扇与涡轮喷气发动机（ＳＴＦＦ－ＴＪ）、空气涡轮火箭组合发动机（ＳＴＦＦ－ＡＴＲ）的性能优势，讨论了ＳＴＦＦ发动机与飞机的一体化问题，分析了影响安装阻力的主要因素。指出ＳＴＦＦ发动机比传统的涡轮风扇发动机（ＴＢＥ）的摩擦阻力系数低，升阻比高，说明这是一种有巨大潜力的新型发动机。

Abstract: his paper is dealt with the study of the supersonic through-flow fan engine from different Points of view. First,the working modes of supersonic through-flow fan is discussed,then theadvantages of STFF-TJ and STFF-ATR engines in performance levels are analyzed and, finally, astudy on STFF engine airframe integration and the loading factors which affect the installed wavedrag is conducted, It is suggested that compared with the conventional TBE, STFF engine exhibitslower friction drag and higher value of maximum L/D,which shows that the new engine is of greatPotentialities with a promising prospect of application.
