Abstract

The invention relates to the technical field of aerospace, in particular to a ramjet system. The ramjet system comprises a fuel supply mechanism, a combustion mechanism and an ejection mechanism which are sequentially communicated, wherein the fuel supply mechanism comprises a first shell, and the first shell is internally provided with a gas supply unit with a gas supply part, a solid supply unit with a solid supply part and an injector communicated with the solid supply unit; a conduction gap is formed between the gas supply part and the solid supply part; and the conduction gap is used for guiding gas in the gas supply part into the solid supply part. According to the invention, carbon dioxide fluidizing gas accelerates at the conduction gap to the maximum speed and enters the solid supply part, the conduction gap at the moment is equivalent to a sonic nozzle, on the one hand, the flow of the carbon dioxide fluidizing gas can be controlled, on the other hand, the speed of the carbon dioxide fluidizing gas is increased, the shearing capacity of the carbon dioxide fluidizing gas is improved, stable supply of the carbon dioxide fluidizing gas and magnesium powder is guaranteed, and the fluidizing effect is better.

Description

technical field [0001] The present application relates to the field of aerospace technology, in particular to a ramjet system. Background technique [0002] The powder fuel ramjet system is a new type of engine that uses the chemical reaction between powder fuel and gas oxidant gas to generate power. It has the advantages of simple structure, easy maintenance, and high energy density. It is currently used in missiles, Mars exploration, underwater engines and other fields. It has broad application prospects and is one of the most potential engines in future aircraft. [0003] Most of the existing ramjet systems have the problem of unstable fuel supply. [0004] Therefore, there is an urgent need for a ramjet system to solve the technical problems in the prior art to a certain extent. Contents of the invention [0005] The purpose of the present application is to provide a ramjet system to solve the technical problem of unstable fuel supply of the ramjet system in the prio...
