【摘要】 应用计算机辅助分析(CAA)与计算机辅助绘图(CAD)方法,确定微型固体火箭发动机燃烧时间t_b。该方法自动化程度高、精度好,有可靠的理论依据。用它替代传统的没有任何理论根据的手工画角分线法,以提高小型固体火箭发动机内弹道数据处理的精度和速度是十分必要的。实践证明这是一种科学的可行的方法,值得推广。更多还原

【Abstract】 The computer aided analysis(CAA)and computer aided drawing(CAD)tech- nique is applied to determine the burning time t_b of a micro solid rocket motor.The tech- nique on the basis of theory features a high automatic degree and a high accuracy.It is nec- essary for it to take the place of the classical angle bisector drawn by hand in order to in- crease the accuracy and speed of the internal ballistic data processing of the micro solid rocket motor.The practice has proven that it is a scientific and feasible technique and wor- thy to be spread.更多还原
