Abstract

This paper presents the details of a set of aeroelastic stability analyses of the Hyper-X free flyer vehicle employing Euler-based steady and unsteady flow solutions. These results are also compared with piston theory using the conventional as well as a system identification procedure. Both structural and fluids discretization are achieved by the standard finite element method. Analysis results indicate good correlation of various procedures in the simulation of aeroelastic stability phenomenon. Also, CPU time required for such an analysis is indicative of the feasibility of CFD-based flutter and aeroservoelastic stability analysis of complex aerospace vehicles using currently available computing resources.
