流场。随着第二个气动盘直径的增加,其附近再附
激波强度不断增加,气流流经该激波后总压降低程
度更大,另一方面,钝体壁面前的主回流区范围也逐
渐增加,这都降低了钝体壁面再附激波强度,从而使
得钝体壁面压力系数和斯坦顿数降低,构型总阻力
总体上呈下降趋势。在研究参数范围内,第二个气
动盘直径 D2/D=0.6 的减阻杆-双盘-槽道组合构型减
阻防热整体效果较好,相比减阻杆-单盘构型,总阻
力系数降低了 24.70%,钝体壁面斯坦顿数峰值降低
了 53.63%。
未来会继续研究减阻杆直径等参数对组合构型
流场结构及减阻防热性能的影响规律,并分析组合构
型的非定常特性以及三维构型在非零攻角下的减阻防
热性能。在此基础上,进一步开展相关实验研究。
