Problems solved by technology

However, in the research on the combustion of aluminum-based solid propellants, the influence of the test bench and the wall of the combustion chamber on the combustion of the propellant cannot be ignored. Therefore, it is necessary to suspend the propellant and observe the combustion of the propellant in space.

Abstract

The invention discloses an experimental device and method suitable for suspension combustion of a solid propellant. The experimental device comprises an ignition combustion device used for igniting the solid propellant, a gas delivery device used for delivering gas and a combustion analysis device used for monitoring the solid propellant, wherein the gas delivery device is communicated with the ignition combustion device; the combustion analysis device is arranged on one side of the ignition combustion device; the ignition combustion device comprises a combustion chamber, an ignition mechanism and a combustion channel, the ignition mechanism and the combustion channel are arranged in the combustion chamber, the solid propellant is located in the combustion channel, the gas transmission device communicates with the combustion channel, and a gas delivery direction of the gas delivery device faces the solid propellant; and the ignition mechanism is located on the side opposite to the side, facing the gas delivery device, of the combustion channel. During an experiment, the ignition mechanism is heated to reach an ignition point of the solid propellant, the gas delivery device inputs gas to the combustion channel, the gas blows the solid propellant to be close to the ignition mechanism, and the ignition mechanism ignites the solid propellant.

Description

technical field [0001] The invention relates to an experimental device and method suitable for solid propellant suspension combustion, belonging to the technical field of material performance testing. Background technique [0002] Aluminum combustion is a very promising metal fuel combustion technology today. Due to the large reserves of aluminum, mature mining technology, safe and non-polluting combustion products, and large specific impulse, it has been gradually used in the formulation of various solid propellants middle. In particular, aluminum can be burned in a variety of atmospheres, which can meet the actual needs in multiple application scenarios. However, in the combustion research of aluminum-based solid propellants, the influence of the test bench and the wall of the combustion chamber on the combustion of the propellant cannot be ignored. Therefore, it is necessary to carry out suspension combustion of the propellant and observe the combustion of the propellant...
