运输机尾流场的小型空投物资下落轨迹仿真
|
摘要
为了研究运输机的下洗尾流场对小型物资空投轨迹的影响规律,应用基于位势流理论的涡格法对全机尾流场的速度分布进行数值求解,并建立伞货一体的刚性动力学模型,仿真分析了小型空投物资在载机尾流场影响下的下落轨迹。研究表明,尾流场会使空投物资下落轨迹向飞机飞行方向整体偏移,并且随着载机平飞速度增加,尾流场对空投物资下落轨迹的偏移量反而减小。
This study aims to investigate the influence of airdrop trajectory under downwash flow field of transporter plane. Vortex lattice method based on potential flow theory is used to solve velocity distribution of the downwash flow field. An airdrop rigid dynamic model is established for trajectory simulation of small dropping supplies.Results show that the downwash flow field from the transporter causes the airdrop to move toward the flight direction of the transporter. Furthermore,deviation of the downwash flow on the dropping track is reduced when the plane flies faster.
