Investigation of High Acceleration on the Interior Ballistics of Solid Propellant Rocket Motors

Abstract

An investigation was undertaken on the effects of high acceleration on the interior ballistics of solid propellant rocket motors. A description of the cold flow spin test apparatus and instrumentation is presented. The results of some of the preliminary tests are given and the program for future testing is described. An analytical study is presented which describes various simplified models which account for the effects of rotation on the mass flow and thrust producing capabilities of the nozzle. Results are given for two limiting cases: (1) uniform axial velocity profiles at each plane in the nozzle; (2) uniform angular velocity profiles at each plane in the nozzle. These cases are discussed and a more advanced model is formulated. The complete model is described and future analytical computations are discussed.
