Abstract

Lifting body type reentry vehicles like the Intermediate Experimental Vehicle (IXV) tend to be aerodynamically unstable in the tran- and subsonic flight regime. To determine the dynamic behaviour of the vehicle the free oscillation technique is used. Numerical simulations of corresponding wind tunnel tests have been carried out by coupling the solvers for the outer flow and the vehicle motion. For the considered test conditions in super-, tran-, and subsonic flow simulations and experiments show dynamically stable behaviour
