Abstract

The invention discloses an ignition device for discrete particles of flowing metal fuel, which comprises a jet burner module, a xenon lamp ignition module, a combustion diagnosis module and a controlmodule. According to the invention, a pressure burner is adopted as a metal fuel particle combustion environment, ignition of metal fuel particles within a pressure range of 0-5 Mpa can be realized, interference on combustion flame of the metal fuel particles is avoided, and flame overlapping is avoided.

Description

technical field [0001] The invention relates to an ignition device for metal fuel, in particular to a device for igniting discrete particles of fluid metal fuel. Background technique [0002] Metal fuel has a very high theoretical calorific value and has become one of the important energetic components in chemical rocket propellant formulations. Common metal fuels include not only magnesium, aluminum, titanium, boron and other metals or metalloids, but also compounds, alloys and composites composed of two or more metals and metalloids. In order to improve its ignition and combustion characteristics, the vast majority of metal fuels will be processed into micron or nanoscale particles, called metal fuel particles or powders. In order to realize the full combustion and energy release of metal fuel particles in the rocket engine, it is necessary to study its ignition and combustion characteristics in order to scientifically design the propellant formula and engine structure, a...
