| 摘 要： | 对极小展弦比背鳍进行了风洞实验和CFD分析。研究表明：亚声速大迎角下背鳍涡破裂影响不严重,且涡破裂迎角较大;正侧滑通常使背鳍法向力增加,负侧滑使法向力降低;CFD分析证实了大负侧滑条件下翼片法向力会变成负值,从而引起十字翼在倾斜条件下滚转力矩发生突变。

| Abstract: | Dorsal fin wind tunnel test and CFD analysis were conducted.For dorsal fin the effect of vortex breakdown is not severe at subsonic speed and at high angles of attack.Positive sideslip increase the normal force of dorsal fin and negative sideslip decrease it.CFD approves that dorsal fin normal force can change to negative at high sideslip angles which will affect the rolling moment of configuration with cruciform fins. |
