【摘要】 根据一种火箭的固体发动机的要求，研究了开槽管形装药（减面形）的设计方法，并对减面形开槽管形药柱的槽数、槽长对燃面变化的影响进行了研究，提出了划分燃面变化阶段的依据。经性能试验和飞行试验证明，这种开槽管形装药（减面形）设计是正确的。更多还原

【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.更多还原
