Comparative Analysis of Aerodynamic Performance between Oversize Modular Parafoil and Oversize Continuous Parafoil
With the increasing demand for aerospace recovery system applications, the recovery mass is increasing, the requirement of parafoil area is becoming increasingly high, and oversize parafoils are paid more and more attention. However, there is not enough research on oversize parafoil at home and abroad. This paper intends to establish the physical model of oversize modular parafoil and oversize continuous parafoil. Based on the k-epsilon turbulence model, the CFD method is deployed to calculate the aerodynamic features of continuous parafoil and modular parafoil under the conditions of no pull-down, single side pull-down and double side pull-down respectively. Results show that there is obviously air supplement in the modular parafoil, which can improve the flow separation, and increase the stall angle of attack. Therefore, the oversize modular parafoil are more suitable for the flight mission with high attack angle and have a wider range of applications. This paper can provide some reference for the selection of oversize parafoils in the future.
