Deployment and recovery device of a rocket engine underwater test bench

Abstract

The invention discloses a device for deploying and recovering an underwater test platform of a rocket engine, which comprises an underwater platform, a load-bearing steel cable, a communication ignition cable, a guiding steel cable, a lifting steel cable, a universal joint, a lifting ring screw, Weights, traction cables, traction rings, shackles and universal joints, and the peripheral equipment are control systems and winches; among them: the underwater rocket engine to be tested is installed symmetrically and reversely on the underwater platform, the lifting ring screws, lifting steel The cable, shackle, universal joint, shackle and load-bearing steel cable are connected in sequence to the underwater platform. One end of the guide cable is connected to the guide cable winch on the deck of the ship, the other end is connected to the weight, and one end of the traction cable is connected to the underwater platform. The platform is lowered, and one end is connected to the guide cable through a traction ring. The present invention adopts the combined use method of two steel cables and one cable, which effectively solves the problems of ignition, signal collection, stand posture stability, steel cables and cables being entangled with each other and the stand cannot be normally laid out and recovered during the underwater test of the engine. problem.

Description

A device for deployment and recovery of a rocket engine underwater test bench Technical field The present invention relates to a kind of rocket engine underwater testing device, particularly a kind of rocket engine underwater test bench The utility model relates to a device for deploying and recovering racks, which belongs to the field of rocket engine testing. Background technique [0002] Underwater rocket engine is a kind of power system working in deep sea high back pressure environment. It has a simple structure, Fast start-up, high reliability, and high-speed propulsion under water for a short time. Thus, underwater missiles, torpedoes, active attack mines, hyperspace One of the main propulsion forces for underwater weapons such as bubble projectiles. Underwater rocket motor is the same as other rocket motors, all need to carry out bench test after designing and processing, with The engine thrust, combustion chamber pressure, internal ballistic characteristics ...

AI Technical Summary

Problems solved by technology

The biggest shortcoming of the machine test simulator is that it can only carry out the scale test of the underwater engine, and cannot carry out the underwater test of the full-scale engine.
