Abstract

The invention relates to an ignition and combustion testing device, and aims to provide a device for ignition and combustion of a primary boron product with high energy density laser. The device comprises an ignition module, an atmosphere control module, a combustion diagnostic module, and a data recording module, wherein the ignition module comprises a high energy density laser device and a transparent ignition combustion tube, a laser tube is fixed on a base via a laser tube support frame, the transparent ignition combustion tube is arranged on an iron stand, and a sample bracket is arranged in the center of the transparent ignition combustion tube. The device provided by the invention can rapidly heat a primary boron product sample to a temperature above the boiling point of boron oxide in several milliseconds, which is far better than the conventional electric heating ignition manner, and can realize rapid ignition and complete combustion of the primary boron product. The laser device has low electric power, and can be used after being supplied with 220V family electricity, resulting in good generality. The laser heating range is centralized, and the energy utilization efficiency is high.

Description

technical field [0001] The invention relates to an ignition combustion test device, in particular to an ignition combustion device for primary boron products. Background technique [0002] Boron has extremely high mass calorific value and volume calorific value, and the propellant composed of boron has good dispersion of specific impulse combustion products, and can also significantly reduce the loss of two-phase flow at the throat of the nozzle. It is considered to be one of the propellants Good quality filler. During the primary combustion process of the boron-rich fuel-rich propellant, due to the poor oxygen environment and low temperature, it cannot be fully ignited and burned. The primary combustion products containing a large amount of boron particles enter the afterburner from the gas generation chamber and are mixed with air to complete the process. Combustion, and release a lot of heat, the superior energy performance of the boron-rich fuel propellant is mainly bro...
