Design and Test for Servo Fluid Conveying Device

针对飞机倒飞、滚转等大姿态时的流体液面变化而造成的流体输送中断的问题,设计了一种新型的随动流体输送装置。装置采用全机械的设计方法,流体入口能跟随液面位置的变化围绕连接部件旋转。对该装置进行性能试验,结果表明,在增压压力的作用下,装置能满足飞机平飞、滚转、俯仰状态下流体的可靠输送。

Aiming at fluid conveyance interruption occurred in the process of large attitude flight of aircraft, such as in inverted flight and free-roll, a new servo fluid conveying device was devised. Adopting an all mechanical design, the inlet of the device can rotate around the axis of the interconnecting part, following the fluid surface. The performance test result shows that, under boost pressure, the servo fluid conveying device meets the requirement of reliable fluid conveyance during level flight, free-roll and pitching.
