Abstract

The invention discloses a test device and a test method for ignition combustion of energetic material powder and lossless cooling of a condensed-phase combustion product. The device comprises a combustor main body, a sample bracket located in an inner cavity of the combustor main body, an ignition assembly, a condensed-phase combustion product cooling assembly and a pressure protection assembly located outside the combustor main body. The condensed-phase combustion product cooling assembly is used for carrying out lossless cooling on the condensed-phase combustion product of the energetic material powder, and the risk that the substance composition and the morphology structure of the condensed-phase combustion product are changed in the cooling process can be remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of energetic materials, and relates to an ignition combustion and combustion product collection device, in particular to a test device and test method for ignition combustion of energetic material powder and non-destructive cooling of condensed phase combustion products. Background technique [0002] Energetic materials can undergo sustainable reactions without the participation of external substances, and release huge energy in a short period of time, and are widely used as fuels for military products such as propellants, propellants, and explosives. Solid energetic materials often exist in the form of powder, called energetic material powder. For different applications, energetic material powders with different properties need to be used. At present, researchers have synthesized tens of thousands of energetic material powders, but the properties of most of them have not been fully grasped, so it is diffic...
