| Abstract: | Based on the analysis of longitudinal and lateral modal characteristics of a certain kind of transport during airdrop reposition and traction period at ultra-low altitude, the aerodynamic characteristics of transport in ground effect were investigated, and the influence of ground effect on the airdrop task performance was evaluated by referring to the flying quality standards. The results can provide theoretical basis for the design of airdrop flight control and corresponding ground experiments. |
