Description

technical field [0001] The invention belongs to the technical field of underwater vehicle power, in particular to a water-absorbing solid fuel ramjet performance test device. Background technique [0002] The water-absorbing ramjet engine uses a specific metal-containing solid propellant, uses water as the working medium, and uses the high-temperature and high-pressure gas produced by the combustion of the solid propellant to chemically react with water or the water is heated and evaporated into water vapor to form a bubble-like gas-liquid two-phase flow , ejected from the nozzle to generate thrust, which can greatly increase its speed and thrust, and has very broad application value. At present, it is difficult to complete the underwater experiment of water-absorbing solid-fuel ramjet in the existing technology. Due to the limitation of underwater conditions and complex combustion reaction process, the required experimental system is complex and expensive, and the performan...
