Underwater rocket projectile thrust performance testing device

Abstract

The invention discloses an underwater rocket projectile thrust performance testing device, and relates to the technical field of underwater weapon thrust testing. The underwater rocket projectile thrust performance testing device can simulate the underwater working environment of a rocket projectile, objectively reflects the working performance of the underwater rocket projectile, and provides technical reference for further optimization design of the underwater rocket projectile. The device comprises a rocket projectile engine, a thrust test bench, a data acquisition system, a high-pressure steam bottle and a temperature control box. The underwater rocket projectile thrust performance test device provided by the invention can realize underwater environment thrust test, simulates the working process of a projectile body engine in a real environment, overcomes the defect that a traditional ground thrust test experimental method does not consider the influence of an aqueous medium, and completes multi-path data acquisition, the control over the water inlet flow of high-pressure water vapor, and online calculation of underwater elastic thrust performance under the control of a computer. The data obtained by the method can reflect the working condition of an underwater projectile more objectively and truly, and has the advantages of high precision, high reliability and the like.

Description

Technical field[0001]The present invention relates to the field of underwater weapons thrust test, and in particular to a water rocket thrust performance test device.Background technique[0002]As a preset equipment for underwater defense, the new underwater rocket weapon engine system usually uses nano metal aluminum powder as a fuel, water is an oxidant, and has a severe reaction in a certain condition, release a large amount of thermal energy, and the energy density is ordinary. 4 times the fuel can greatly increase its operations and speed.[0003]The propellant in the engine system is typically employ HTPB (terminal hydroxyl polybutylene) as a binder, a small amount of AP (ammonium oricate) is an oxidizing agent, and the nano metal aluminum powder is fuel, and the aluminum powder content is as high as 80%. Aluminum-based fuels react multiple times in combustion of water into the combustion chamber after the first combustion of the combustion chamber, generate a large amount of hydr...
