Metal hydrogen storage powder water ramjet engine

Abstract

The invention discloses a metal hydrogen storage powder water ramjet engine. The engine comprises a shell, a pressurization system and a powder storage tank. A storage cavity, a conical mixing cavity, a combustion chamber and a tail spraying cavity are sequentially distributed in the center of the shell in the axial direction. The pressurization system and the powder storage tank are arranged in the storage cavity; the pressurization system comprises a supercharger, a main pressurization pipe and branch pressurization pipes; a piston is arranged in the powder storage tank and divides the powder storage tank into a pressurizing chamber and a powder storage chamber; a powder spraying pipe is arranged at the right side of the powder storage chamber; and water injection nozzles are uniformly distributed at the position, at the periphery of the conical mixing cavity, of the shell along the circumferential direction. Metal hydrogen storage powder is wrapped by pressurization gas and enters the combustion chamber through the powder spraying pipe through the pressurization system, and the powder is prevented from blocking the powder spraying pipe; and the metal hydrogen storage powder entering the combustion chamber is fully mixed with water mist sprayed into the combustion chamber through the water injection nozzles. In addition, under the combustion-supporting effect of a small amount of oxygen, the ignition difficulty is remarkably reduced, the reaction stability is enhanced, and the thrust performance is better.

Description

technical field [0001] The invention relates to the field of water ramjet engines, in particular to a metal hydrogen storage powder water ramjet engine. Background technique [0002] The water ramjet engine is a new form of underwater power and a revolutionary development of underwater power. The new propulsion system developed by water ramjet combined with "supercavitation" can become a sharp weapon for high-speed penetration, thereby changing the combat style of underwater weapons. According to the different supply forms of propellant, the current research on water ramjet at home and abroad can be classified into two types: grain type and powder type. [0003] In the grain-type engine, the grain carries a certain amount of oxidant and binder, which may affect the performance of the engine due to the lack of metal-containing fuel. However, when the metal is excessive, the metal may not be precipitated from the grain, and the stable combustion cannot be achieved. [0004] ...
