Problems solved by technology

However, the traditional target line method can only test the average velocity of energetic materials under a single pressure, and cannot measure the relationship between the burning rate of explosives and the pressure change; the pressure of the test combustion environment is low; the burning rate of the test does not exceed 100mm / s, and the application range is narrow

The calculation of the burning rate of energetic materials by the traditional closed burner method requires the state equation of the product gas and the accurate treatment of heat loss, which is difficult to realize; the uniformity of combustion cannot be verified, and the test burning rate data is unstable; it is not easy to control
