Hydroxylammonium nitrate(HAN) is a main component of the new liquid rocket propellants.

According to the complexity of precisely measuring propellant temperature before firing rocket projectiles, with present widely used computer numerical simulation method, the article has simulated 130 rocket propellant transient temperature field by program and also measured propellant temperature by designed experimental unit.

Owing to peculiar function, working condition and safety requirement of rocket propellants, multiform protection means are necessary against them, especially preventing respiration organs of human body from hurting.

This pap er summaries the application and development of respiratory protective equipment and analyses the protecting request against the liquid rocket propellant.

By studying and summing up the failure physical models in common use,this paper advanced a cumulative damage-reaction theory life model to the storage and usage of solid rocket propellant,and,by calculating examples,demonstrated this model clearly.

By using real time holographic interferometry,the solid rocket propellant combustion process were investigated and recorded by a video camera with a shooting speed of 25 frames per second and the maximum electronic shutter speed of 1/2000 second.

Anti-stick coatings for stripping of solid rocket propellant, which could be cured at room temperature had been successfully developed.

Studies on the long term effect of liquid rocket propellant on rates with intoxication and blast combined injuries;
