Engine based on vane-type metal-water reaction propulsion unit

Abstract

The invention aims to provide an engine based on a vane-type metal-water reaction propulsion unit. The engine comprises a solid grain, a first combustion chamber, a second combustion chamber, a jet pipe, a water inlet pipe and helical blades, wherein the water inlet pipe passes through the solid grain, the first combustion chamber and the second combustion chamber; one end of the water inlet pipe is installed in the solid grain and the other end is installed in the position at the rear side of the second combustion chamber and close to the jet pipe by a water pipe support; the water inlet pipe is provided with blowholes; and the helical blades are installed on the water inlet pipe. The engine has the following advantages: the water inlet pipeline is simply arranged and does not occupy the volume outside the combustion chambers, thus ensuring the structure of the whole propulsion unit to be compact; the incoming water directly reaches the center of the flow field, thus greatly improving the reaction rate; the water jet amount is determined according to the number of the jet orifices and the diameter of the centrifugal nozzle and is easily controlled; and the arrangement of the helical blades effectively enhances the turbulence in the combustion chambers, thus remarkably improving the blending effect.

Description

technical field [0001] The invention relates to an engine, specifically an engine used for water surface and underwater operations. Background technique [0002] At present, the combustion mechanism that produces high-temperature gas by the reaction of water and gas rich in active metal particles, and then works through the nozzle or turbine device has attracted people's attention and has been introduced into the propulsion system of underwater vehicles. However, research in this field is still a brand-new topic in China, and some key technologies, such as the organizational form of combustion, the water intake method of the propulsion system and the distribution of supply, have not yet been well resolved. The traditional engine structure cannot complete the mixing process of water vapor and gas well, which greatly reduces the reaction rate and affects the engine performance. Efficiently mixing water vapor and gas, giving full play to their chemical properties, and releasin...
