Description

technical field [0001] The invention relates to the field of fuel supply for powder ram jet engines, in particular to a micro-powder distribution fluidization device. Background technique [0002] Powder-fueled ramjet uses high-energy metal or boron powder as fuel, which has the advantages of adjustable thrust, high specific impulse of liquid fuel ramjet and safety, reliability and simple structure of solid rocket ramjet, especially solid / powder or liquid / powder fuel combination For ramjet, the addition of powder fuel can not only greatly improve the performance of traditional ramjet such as specific impulse, but also improve and increase its original functions. It is one of the new generation missile power devices with great development potential. [0003] The powdered fuel flows in a gas-solid two-phase form under the action of the fluidizing gas, so it has strong flow rate controllability, enabling the powdered fuel ramjet to have multiple starts and thrust adjustment fun...
