Abstract: (5008 Views)

Recent studies in solid composite propellants indicate that acceleration field cause to increase in burning rate. Relation between acceleration field and burning rate of propellant have an important effect on missile systems ballistic, especially on perforated grain missiles. If these effects has neglected in design phase, the pressure-time profile shifted out of acceptable rage and result in increasing pressure and motor fail. Therefor in order to design rockets, need to know the acceleration effect on solid rocket performance. In this work influence of acceleration field in burning rate of non-aluminized and aluminized propellant has been investigated. Also models with a good accuracy to predict the performance of propellant in accelerated field, has been introduced.

Keywords: Solid Propellant, Spin Acceleration, Burning Rate, Thrust
