将翼柱型药柱的18个关键尺寸定义成可变多数，通过人机交互输入具体的数值，构造任意烧去肉厚下的药柱模型，并计算该模型的体积。由Ab=△V／△e计算燃烧面积的大小，并进而计算出燃烧室压强和发动机推力。把任意烧去肉厚下的药柱模型和相对应时刻的压强-时间、推力-时间坐标制作成幻灯文件，通过计算机显示器屏幕连续演示，达到动画模拟的效果。
Define the 18 key dimensions of the wing column as a variable majority, and input the specific values through the human-computer interaction to construct the column model with arbitrary burning depth and calculate the volume of the model. From Ab = △ V / △ e to calculate the size of the combustion area, and then calculate the combustion chamber pressure and engine thrust. The arbitrary thickness of the burning under the grain model and the corresponding time pressure - time, thrust - time coordinates made into a slideshow file, through the computer monitor screen continuous demonstration to achieve the effect of the animation simulation.
