反流推力矢量喷管是当前从事推力矢量控制技术的人们极为感兴趣的方案之一,它属于流体作动式推力矢量喷管中的一种。这种喷管主要是通过对二股吸气反流的控制达到使喷管主流改变方向,进而实现航空发动机的推力矢量控制。该技术的最大优点是省掉了常规机械作动系统和一些运动件,因而,不但减轻了重量、降低了成本,而且还提高了矢量系统的反应敏捷度。若该技术在应用上得以实现,无疑又是航空发动机一次革命性突破,难怪有人把它称之为“跨世纪新技术”。
Backflow thrust vector nozzle is currently engaged in thrust vector control technology is one of the most interested program, which belongs to the fluid actuated thrust vector nozzle in one. This nozzle is mainly through the two shares of the suction flow control to achieve the mainstream nozzle change direction, and then achieve the thrust vector control of the aero-engine. The biggest advantage of this technology is the elimination of the conventional mechanical actuation system and some moving parts, thus not only reducing the weight, reducing the cost, but also improving the responsiveness of the vector system. If this technology can be realized in application, it is no doubt a revolutionary breakthrough in aero-engine. No wonder someone calls it “new technology in the new century.”
