| Abstract: | the design method for slotted-tube propellant grain (regressive burning)is developed accordingto the technical requirements for a new type of solid rocket motor.The effects of the number and length ofthe slots on the change of burning surface are investigated,then the principle for distinguishing the combus-non phase is suggested.The design method of the slotted-tube grain is proVed to be available by the performance measurement and rocket flight test. |
