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。
From different perspectives, the ultrasonic flow fan engine is discussed. The operating mode of the ultrasonic flow fan (STFF) and the operation of the supersonic flow fan and the turbojet engine (STFF-TJ) and the air turbine rocket combination engine STFF-ATR). The integration of STFF engine and aircraft is discussed. The main factors affecting the installation resistance are analyzed. It is pointed out that the STFF engine has lower frictional drag coefficient and higher lift-drag ratio than the traditional turbofan engine (TBE), indicating that this is a new type of engine with great potential.
