Description
Summary:Temperature load is one of the loads that propellant grains are often subjected to. Temperature shock or temperature cycling will affect the structural integrity of propellant grains to a certain extent. How to ensure that the propellant grains meet the structural integrity requirements under temperature load conditions and ensure equipment the significance of a smooth launch is very important. In this paper, the HTPB propellant sample response analysis test is carried out based on the global temperature environment distribution of different temperature grades, and the extreme low temperature impact simulation experiment is carried out for the grains under the specific structure considering the impact of extreme low temperature conditions, and finally different models are constructed. The constitutive model of HTPB propellant under extreme low temperature, its grain meets the structural integrity criterion after being subjected to the impact of extreme low temperature.
