运输机尾流场的小型空投物资下落轨迹仿真

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.
