Abstract

The invention provides a powder combustion experiment platform which mainly comprises a fuel gas conveying system, a water cooling circulation system, a nitrogen system, a test bed and a flat flame combustor, and the fuel gas conveying system comprises an air system, a methane system and a mixed fuel gas pipeline. By means of the powder combustion experiment platform, the powder combustion performance can be better observed.

Description

technical field [0001] The invention belongs to the technical field of aerospace combustion testing, and in particular relates to a powder combustion experiment platform. Background technique [0002] Powder-fueled ramjet is a new type of ramjet that uses high-energy non-metallic powder or metal powder as fuel and ram air as oxidant and working medium. Due to the use of metal powder fuel with high energy density, the engine has the advantages of high specific impulse, good safety, low cost and adjustable thrust. [0003] NASA of the United States and ONERA of France have successively carried out research on related technologies of this kind of engine, mainly including: powder fuel combustion theory and experiment; powder fuel fluidization supply system design and experiment; engine theoretical performance calculation analysis and experiment, etc. [0004] Boron particles are characterized by high quality and high volume calorific value, and are ideal propellant fuel additiv...
