为了合理选择模型支撑形式,在高速风洞进行了直支杆与Z-支杆两种支撑形式的支架干扰研究试验。结果发现,支架对模型带来不可忽略的干扰量,两种支撑形式对升力、阻力与力矩的干扰量随迎角基本上呈线性变化;直支杆由于距离模型较近,对模型尾部带来较大的影响。而Z-支杆对模型尾部影响较小,在全机与无尾两种状态下的干扰量较为相近。
In order to select the model support form reasonably, two kinds of support experiments of the strut support and the Z-strut are carried out in high-speed wind tunnel. The results show that the support can not neglect the model and the amount of interference with lift, drag and torque varies linearly with the angle of attack. The straight strut brings the tail of the model closer to the model Greater impact. However, the Z-strut has less influence on the tail of the model, and the interference in the two states of the whole machine and the tailless is relatively similar.
