| 摘 要： | 给出一种直接力/气动力复合控制的空空导弹计算模型,应用CFD软件对其侧向多喷流干扰流场进行了数值模拟;选择四种代表情况,重点研究分析了不同侧多喷流对导弹气动特性的影响。研究结果表明,喷流干扰使得升力系数和俯仰力矩系数减小,并产生较大的偏航干扰力矩,同时喷流的间距也影响俯仰力矩系数和偏航力矩系数。所得结论具有一定的参考价值。

| Abstract: | A kind of compound control air-to-air missile model of direct lateral force/aerodynamic control was put forward.Numerical simulation of multiple lateral jets interaction flow field was performed by using the CFD software.Aiming at four types of instances,different lateral multiple jets interaction effects on missile aerodynamic characteristic was studied emphatically.The result shows that lift force coefficient and pitching moment coefficient will decrease,and bring about the big yawing interfering moment.A... |
