Title Characteristics of combustion of propellant under atmospheric and the cold-wall effect
Abstract
The burning under the cold wall effect is an effect of combustion can be applied with the required materials. the cold wall effect will make combustion of energetic materials instability, resulting in ballistic performance instability, and cause thruster propellant charge is not clean burning and other harmful burning phenomenon. Therefore, this experiment with a double base propellant, using atmospheric combustion test method to study double base propellant combustion characteristics under different atmospheric wall material, get double base propellant combustion process under different wall materials, Thereby establishing the relationship between the wall material and characteristics of combustion of the propellant. The results show that the thermal conductivity of the wall material, the smaller the influence of propellant combustion. Under current water situation and got a good result of the cold wall effect.
Keywords the cold wall effect combustion double base propellant atmospheric characteristics of combustion thermal conductivity
