| contents | Study on the Parameters of Azidonitramine Propellant on Gun Barrel Thermal‐Chemical Erosion Rui Wu Yi‐jie Xiao Wei‐tao Yang Qiang Li Yu‐cheng Zhang Propellants, Explosives, Pyrotechnics ABSTRACTTo comprehend the erosion patterns of gun barrels and prolong their service life, the erosion tube method of the vent vessel was employed to test the erosion characteristics of gun propellants at different loading densities. The impact of flame temperature, gas composition, and maximum pressure on the erosion characteristics of diazidonitrazapentane (DIANP) propellant was investigated during combustion. The results indicate that by altering the thickness of the burst disk and loading density of the propellant, the breakthrough pressure can be adjusted, and thereby the maximum pressure during combustion can be controlled. For DIANP propellant, a relationship between the propellant flame temperature, gas composition, and maximum pressure with the mass erosion rate was established. Predictive equations for erosion including chamber pressure, gas composition, and flame temperature were built. Meanwhile, the functional relationship between the rate of mass erosion and bore wear was given. Hence, the wear on the inner diameter of the barrel can be predicted by the rate of mass erosion. The rank of gas contributions is as follows: CO2 > H2O > H2 > CO > N2, with respective influence factors of approximately ‐0.147, ‐0.091, 0.066, ‐0.016, and ‐0.014. Erosion characteristics of propellants at high pressure are about 3–4 times higher than at low pressure. The erosion characteristics of DIANP propellant exhibit an exponential relationship with flame temperature of propellant and gas composition, which is linearly related to maximum pressure. Meanwhile, for the DIANP propellant, the erosion characteristics are, in descending order, flame temperature, gas composition, and maximum pressure. 10.1002/prep.12021 http://onlinelibrary.wiley.com/termsAndConditions#vor |
