It has been maked for immediate and statistical analysis that the calculation about the work order parameter of the base - bleed - rocket is calculated in the taguchi method , its influencing trend is bring out in the open , the theoretical base is settled for confirming the greatest combination about the work order parameter of the base - bleed - rocket . the multi - objectile optimal design model is established that the indexes have been taked into account first and synthetically , such as physical parameter range lethality power strength and flight stability and so on , the program is compiled and the example is calculated . the true worth of the theoretical work in this paper is validated by flight experimentation of 130mm hybrid base - bleed - rocket extended - range principium projectile 本文进行了底排?火箭复合增程弹工作时序参数正交试验设计的直观分析与方差分析,揭示了每个参数对射程计算的影响趋势,为进一步确定底排?火箭工作时序参数值的最佳匹配组合奠定了理论基础;建立了底排?火箭复合增程弹多目标优化设计模型,该模型首次综合考虑了底排?火箭复合增程弹的结构特征参量、结构强度性能、飞行稳定性、威力性能和射程指标,编制了相应的分析程序,进行了算例计算;完成了130mm底排?火箭复合增程原理样弹的结构设计与飞行试验,其试验结果验证了本文理论研究工作的实际应用价值。
