Abstract : The development program for a low volume integral booster for Ramjet powered missiles included design and analysis tasks for full scale flight-weight case bonded and stress free viscous system(SVS) motor designs. In each case minimum motor caselengths were determined to meet specified performance requirements. A comprehensive propellant grain structural analysis was done for the case bonded motor to define grain retention details. The design tasks were supplemented with a laboratory study effort. This included (1) optimization of an 87% total solids HTPB propellant formulation, (2) study and development of methods of accommodating a unique bond interface system which required radial outgassing holes in the silicone internal booster insulation, and (3) laboratory evaluation of key aspects of the SVS as they relate to the booster requirements. Design and fabrication of five analog motors and heavywall full scale motor hardware was also initiated prior to redirection of the program scope by AFRPL.
