| Abstract: | Based on the background of the research of precision airdrop system, a 6-DOF nonlinear dynamic model of the parafoil system is established, making use of the knowledge of motion dynamics and aerodynamics comprehensively. The model consists of three degrees of freedom system along the centroid of the translation and three degrees of freedom around the centroid rotation system. According to this model, the overall motion of the parafoil system is analyzed (including translational trajectory and attitude, etc.), and the influence of constant wind field on the flight characteristics of the parachute system is studied. The main flight parameters of the parachute system in the gliding, turning and the bird are obtained, which provide an important theoretical basis for the flight control system design |
