Continuous gel and pasty propellant supply device for rocket engine

Abstract

The invention discloses a continuous gel and pasty propellant supply device for a rocket engine. The continuous gel and pasty propellant supply device comprises a mechanical transmission, a piston supply delivery device and a propellant storage and output device; the transmission comprises a reduction gearbox, couplings, a servo motor with an adjustable rotational speed, a ball screw base, ball screws and nut sliders; the piston supply delivery device comprises piston sleeve rods, a piston cylinder, end check valves of the piston cylinder and side check valves of the piston cylinder; the propellant storage and output device comprises a transition cavity and a propellant storage tank. The continuous gel and pasty propellant supply device has the advantages that the servo motor and the ball screws are used as power devices, so that the sliders can drive a piston to bidirectionally reciprocate, and propellants in the storage tank can be continuously injected into the transition cavity via the piston cylinder under opening and closing actions of the check valves; the rotational speed of the servo motor can be adjusted, so that the supply flow rate of the propellants can be effectively controlled; components of the continuous gel and pasty propellant supply device are high in interchangeability, and accordingly a function for continuously supplying different propellants or continuously supplying the propellants under different working conditions can be realized.

Description

technical field [0001] The invention belongs to the technical field of rocket engines, in particular to a continuous supply device for gel paste rocket engine propellants. Background technique [0002] Gel (paste) propellant is a new type of non-solid and non-liquid propellant, which belongs to the category of non-Newtonian fluid. It has incomparable advantages in terms of safety, application and storage. It is the most developed in the 21st century. One of the most promising special propellants has become a hot research topic in various countries. Gel paste rocket motor has the advantages of simple structure, large thrust, large thrust adjustment range, long working time, super high burning rate, filling coefficient close to 1, and multiple ignition and start-up. It is used in missile weapons , Space delivery, underwater torpedoes and civilian fire extinguishing devices and other fields have a wide range of application prospects. The former Soviet Union used paste propell...

AI Technical Summary

Problems solved by technology

This solution can meet the requirements for precise flow control, but it cannot meet the requirements for the continuous supply of propellant. The device is only used for the supply of paste propellant under a single range of rheology, and the application range is only in the experimental and theoretical research stage
