摘 要:通过正交实验,分析低-高马赫数两级串联吻切锥乘波体在6马赫速度下容积率、升阻比与设计参数之间的关系,并建立二元的非线性回归模型得到升阻比和容积率关于参变量的半经验公式。经过多目标引力算法的优化得到一组关于升阻比和容积率的Pareto最优解集,参照解集选择两级串联吻切锥乘波体的设计参数。优化后两级乘波体能够在超声速到高超声速过程中保持良好的气动特性,尤其是在设定巡航速度,具有高升阻比且下表面气流封闭性较好。Through orthogonal experiment,the relationship between volume ratio,lift-drag ratio and design parameters of two-stage series cut cone wave body with low-high Mach number at 6 Mach velocity was analyzed.The semi-empirical formulas of lift-drag ratio and volume ratio with respect to parameters were obtained by establishing a binary nonlinear regression model.Through the optimization of multi-objective gravity algorithm,a set of Pareto optimal solution sets about lift-drag ratio and volume ratio were obtained,and the design parameters of two-stage series kiss tangent cone wave body were selected according to the solution set.After optimization,thetwo-stage series osculating cone wave ride can maintain good aerodynamic characteristics in the process from supersonic to hypersonic,especially when the cruising speed is set,it has high lift-drag ratio and good airflow sealing on the lower surface.
