This paper studied the aerodynamic performance changes of small and oversize modular parafoil in a wind field with continuous changes in wind direction. The results indicate that the aerodynamic performance of small parafoil undergoes significant changes when the wind direction reaches 80 ° angle of attack per second. However, the oversize parafoil undergoes when the wind direction reaches 8 ° angle of attack per second. It can be concluded that super large combination parachutes are more susceptible to changes in wind direction.
