Abstract:

A structural propellant concept was developed which would permit utilization of high-energy propellants, with marginal physical properties, in rocket motors. The problems associated with its implementation include the evaluation of burning rates of structural propellants, the determination of structural aspects of reinforced propellants, and the development and testing of propellant grains. The burning rate of propellant strands containing metal laminations was increased by a factor of three or more over that of strands without laminations. From theoretical evaluation of the use of structural elements in propellant grains, it was concluded that incorporation of proper reinforcement into propellant grains can produce a 50 to 75 reduction in propellant stress. The low binder content of high-energy propellants caused poor flow characteristics. This property, coupled with exceptional energy release by the propellant, necessitates that new handling procedures for preparation of burning strands and propellant grains be developed. An isostatic pressure technique for forming propellant strands, and a remotely operated propellantgrain forming procedure were established.
