According to a multi-node model

this paper has constructed dynamics equations of conical parachute system to simulate distortion process of the flexible canopy in the opening process.By combination of dynamics equations code and computational fluid dynamics(CFD) software

the fluid-structure interaction study of the parachute was carried out

and the change of its shape and flow flied

inflation time

the rate of decline

the distant of decline

and other relevant data were achieved in agreement with foreign research results.
