摘要
针对传统火箭弹气动力工程算法中大量的查阅图表进行手工插值带来的不便和误差,文中利用Auto-CAD软件,通过AutoLISP语言编写程序对火箭弹空气动力图表数据进行选取,并转换为数据文本文件,再利用BASIC语言编写插值程序对数据文本文件进行插值处理,进而完成火箭弹空气动力模型的计算。经过实际计算验证,计算速度快,精度高,结果可靠。
There are a lot of inconvenience and errors in manual interpolation of the graphs and tables in traditional engineering method of rocket projectile＇s aerodynamic calculation. The paper programs in AutoLISP in AutoCAD environment to select useful data from the graphs and tables of rocket aerodynamic, and convert to data text file. Then programs in BASIC to interpolate the data, and complete the calculation of the model of rocket projectile＇s aerodynamic. Verified by actual calculation, the method has fast calculation, high precision and reliable result.
