The burning pressure-time diagrams were predicted and measured for the spinning solid propellant rocket motors of internal burning star configuration. To predict pressure histories the acceleration-induced and orientation dependent burning-rate augmentation data of a solid propellant from slab motor tests were entered into a grain regression program. Spin tests were conducted using the 140φ motor of the CMDB and composite propellants at spin rates of 0~870 rpm. The spinning full-scale motors were also tested by means of“Spinning Solid Propellant Rocket High Altitude Test Facility”of National Aerospace Laboratory, Kakuda Branch. The measured pressure histories were compared with the computed ones. Futhermore, the grain surface profiles obtained by the extinction test of the 140φ motor were also compared with the calculated ones.
