侧向来流对翼伞气动性能的影响

In this paper, for a new type of wing parafoil structure, the aerodynamic performance of the parafoil is analyzed and studied by CFD method, and the change rule of the aerodynamic coefficient of the parafoil is obtained through numerical simulation, and compared with the traditional wind tunnel experimental data, which verifies the validity of the CFD simulation; and then the influence of lateral incoming flow on the aerodynamic characteristic of the parafoil at different angles is analyzed with the different wingspan lengths of the parafoil as the research object, providing a reference for the lateral control of the parafoil system.
