| Research Abstract |
To evaluate the efficiency of the reentry vehicle system with the inflatable decelerator, we performed wind tunnel experiments and CFD analyses. The results from both wind tunnel experiments and CFD analyses indicate that the inflatable decelerator can produce a sufficient aerodynamic lift force and the lift-to-drag ratio by tilting the decelerator. The trajectory analyses with estimated aerodynamic characteristics were also performed to evaluate the efficiency of this system. The results suggest that the inflatable decelerator can reduce both the aerodynamic heating and the deceleration during the reentry flight. From both results we concluded that the reentry vehicle system with the inflatable system could be one of the most reliable candidates for the future reentry vehicle system.
