“…The results showed that the leeward of the test model affected the drag at the transonic and supersonic regimes. Bhaskar [13] researched the influence of the cone angle, the length of the load on the leeward, and the position of the center of gravity for the aerodynamic coefficient of the IAD. The researcher obtained a statically stable configuration according to the results.…”

Inflatable aerodynamic decelerator, as a novel deceleration and recovery technology, has received attention due to its lightweight and freedom from the launch vehicle fairing size constraints for the space mission. Aimed at the aerodynamic characteristics of the inflatable aerodynamic decelerator, this work studied the effect of the cone angle on its drag and discussed the drag varied with the angle of attack under the different cone angles. The simulation showed that the drag was affected by the cone angle and increased locally with the angle of attack. Furthermore, the larger cone angle was beneficial to the stability of the flow field on its leeward in the case of a high Mach number. The math model of drag with the Mach number and the angle of attack was obtained by fitting the data, which provided favorable support for the prospective discussion of the flight dynamics characteristics.
