| Abstract: | The effects of the contents of fine ammonium perchlorate(AP) and plasticizer di-2-ethylhexyl sebacate(DOS) and bonding agent LW1 on mechanical properties of high burning rate HTPB/IPDI propellant at -55 ℃ were studied.A high burning rate HTPB propellant formulation with better comprehensive properties and used in the -55 ℃～+70 ℃ broad temperature range was gained. Propellant formulation has better mechanical properties except for properties of high burning rate and energy. Maximum tensile strength（σm） of propellant at 70 ℃ is higher than 0.5 MPa. Maximum elongation（εm） at 70 ℃ and 25 ℃ are superior to 45%. Maximum elongation（εm） at -55 ℃ is higher than 30%. |
