The effects of different binders on combustion properties of the gas generating propellant have been investigated.The results show that from the low pressure to high pressure,the amplification of the pressure index of gas generating propellants based on polybutadiene is higher than that of gas generating propellants using polyether as a binder.The molten liquid formed by burning of polybutadiene-based adhesive has poor mobility,and the gas produced by its decomposition can directly enter the gas phase to pa...
