The invention discloses an underwater rocket thrust performance testing device, which relates to the technical field of underwater weapon thrust testing, which can simulate the underwater working environment of the rocket, objectively reflect the working performance of the underwater rocket, and further improve the Provide technical reference for optimized design. The device includes a rocket engine, a thrust test bench, a data acquisition system, a high-pressure water vapor bottle, and a temperature control box. The underwater rocket thrust performance test device provided by the invention can realize the thrust test in the underwater environment, simulate the working process of the missile engine in the real environment, and overcome the defect that the traditional ground thrust test method does not consider the influence of the water medium. The control completes multi-channel data acquisition, high-pressure water vapor inlet flow control, and online calculation of underwater projectile thrust performance parameters. The data obtained by this method can more objectively and truly reflect the working conditions of underwater bombs, and has the advantages of high precision and strong reliability.
Description
technical field [0001] The invention relates to the technical field of thrust testing of underwater weapons, in particular to an underwater rocket thrust performance testing 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 fuel and water as oxidant. Under certain conditions, a violent reaction occurs and a large amount of thermal energy is released for work. The energy density is ordinary 4 times the fuel, can greatly increase its combat range and speed. [0003] The propellant in the engine system usually uses HTPB (hydroxyl-terminated polybutadiene) as the binder, a small amount of AP (ammonium perchlorate) as the oxidant, and nano-metal aluminum powder as the fuel, and the aluminum powder content is as high as 80%. After the initial combustion of the aluminum-based fuel in the combustion chamber, it reacts with the water entering the combustion cha...
