| 摘 要： | 在北航的风洞和水洞中进行了关于双立尾与三角翼组合外形的气动特性实验研究，研究了不同位置的立尾与三角翼的干扰机理。实验选取4个不同后掠角三角翼、每个三角翼设置6种立尾位置，研究这些参数对三角翼气动特性的影响。基于实验结果的分析和比较，提出了气动干扰的机理，比较了立尾的展向和弦向位置的干扰特性，以及三角翼和立尾特性间的干扰，最后给出了最优的立尾位置。

| Abstract: | Experiments on aerodynamic characteristics of delta wings with twin fins were carried out in the wind tunnel and the water tunnel in Beijing University of Aeronautics and Astronautics(BUAA). The research was to examine the mechanisms of vortex-fin interaction. 4 sweep delta wings and 6 fin positions were chosen to investigate the effect of these parameters on the aerodynamic characteristics of the configurations with delta-twin fins. Based on analysis and comparison of the results, the aerodynamic interaction mechanism is presented, the vortex-fin interaction characteristics between chordwise and spanwise fins positions are compared, and the vortex-fin interaction characteristics of the twin-fin configuration is presented. Finally, the optimum position of twin fins is given in this paper. |
