N2 - The single-skinned parawing with different wing loads and lift-to-drag(L/D), as a low wing loading decelerator during the stage of reentry, has been studied in reentry trajectory. The results show that the dynamic pressure and peak heat flux increase with the increase of the wing load, but the overload decreases with the increase of the wing load. When the lift coefficient is increased or the drag coefficient is reduced, the dynamic pressure and the dynamic peak load of the parawing are decreased during the reentry. The heat flux decreases with the increase of the lift coefficient and increases with the decrease of the drag coefficient. It can be obtained that while increasing the lift coefficient, maintaining a large drag coefficient is conducive to alleviating the aerodynamic heating problem during the reentry process.
