Abstract

The invention relates to an energetic fuel technology, and aims to provide a method for measuring ignition energy of solid energetic fuel. Comprising the following steps: on the premise of fixed ignition time, gradually adjusting an input electric power value of a laser during ignition, and carrying out multiple ignition tests by an approximation method; and finally obtaining the minimum value of the input electric power value of the laser when the solid energetic fuel can be combusted in a self-sustaining manner after being ignited. According to the fitting conversion relation, the obtained input electric power value is converted into a laser power value output by a laser, and the ignition energy of the solid energetic fuel is calculated. According to the method, data measurement is convenient, the calculation process is simple and clear, and the finally obtained ignition energy is relatively accurate; common alternating current is adopted as power supply input, so that power control and adjustment of laser emission are very convenient; the experimental system is simple and easy to implement, has wide adaptability to the types of energetic fuels, and has obvious engineering application prospects.

Description

technical field

[0001] The invention relates to the technology of energetic fuel, and aims to provide a method for measuring the ignition energy of solid energetic fuel. Background technique

[0002] Solid energetic fuel has been used in many fields and industries, especially in the field of fuel power, it is widely used and plays an important role. Metal energetic fuels such as aluminum, boron, magnesium, etc., have become irreplaceable energetic components in spacecraft solid engine propellants and explosives due to their extremely high mass and volume energy density, and are important energy sources in propellants. The main factor affecting the effect of energetic fuel in application is whether its energy is fully released, and the premise and main way of energy release are rapid ignition and complete combustion of energetic fuel. Therefore, understanding the ignition process and combustion characteristics of energetic fuels and their derived solid propellants, explosive...
