单燃速单室双推力三维药柱的工程设计

ENGINEERING DESIGN OF 3 D SINGLE PROPELLANT SINGLE CHAMBER DUAL THRUST GRAIN

从工程实际的角度，介绍了单燃速单室双推力三维药柱的设计方法和药型参数优化方法，并通过设计实例纠正了长期以来对以单一推进剂实现两级推力的几个认识误区，为这一新技术成果的应用奠定了基础。

The methods of design and parameter optimization for 3 D single propellant single chamber dual thrust three dimensional grain were introduced and some misunderstandings about it were corrected by a concrete engineering design example. Thus a necessary foundation was established for the use of the new technical achievement.
