Problems solved by technology

[0015] ①The working pressure range is narrow, and the trigger point of separation between stages cannot be adjusted
Because it realizes inter-stage locking and separation based on the deformation of the hose, when the pressure difference between the internal pressure of the water rocket of the lower stage and the pressure of the water rocket of the upper stage reaches 2bar, the separation of the rocket body will be triggered, which limits the maximum storage capacity of the upper water rocket

Abstract

The invention discloses a water rocket pressure-operated interstage locking-separating device, which comprises an upper base, a lower fixing anchor seat, a supporting stand column, a piston-spring assembly and a locking-separating device. The lower fixing anchor seat is sleeved and fixed at the upper end of the rocket body of a lower-stage water rocket; the piston-spring assembly comprises a cylinder barrel, a piston, tension springs and a tension spring hanging rod, the cylinder barrel is fixedly arranged on the periphery of an upper end opening of a rocket body of the lower-stage water rocket in a sleeving mode, the piston is communicated with the interior of the lower-stage water rocket and keeps consistent pressure, the tension spring hanging rod is fixed to the piston, one end of each tension spring is hung at the two side ends of the tension spring hanging rod respectively, and the other end of each tension spring is fixed on the cylinder barrel; and the locking-separating device is fixed to the upper base, and an upper-stage water rocket body is connected to the locking-separating device. According to the device, locking and separating of all stages of the water rocket are achieved, the overall lift limit of the water rocket is improved, the functions of the water rocket and the load capable of being carried by the water rocket are expanded, the working pressure range is wide, and the pressure adjusting freedom degree is high.

Description

technical field [0001] The invention belongs to the technical field of power aviation, and in particular relates to a water rocket pressure-operated interstage locking-separating device. Background technique [0002] The water rocket assisted glider is a common combined power aviation model. This model is mainly composed of three parts: a water rocket, a fixed-wing glider, and a connection-separation device between the two. One of the main competition items of the Air Vehicle Design Challenge. [0003] The working process of the water rocket-assisted glider is similar to that of the launch vehicle: in the boosting ascent phase, the water rocket carries the glider into the sky and separates the glider at the highest point of the water rocket’s flight trajectory; in the descent phase, the water rocket separates the glider Afterwards, the parachute is opened to achieve a soft landing, and the glider performs flight tasks under the control of the pilot or algorithm, such as gl...
