ABSTRACT	The experimental winged space vehicle ?OPE-X?project is progressing. An elastic-rolling mode may be involved in the dynamic characteristics at the launching configuration of this vehicle which is attached to the H-II rocket. Flutter experiments of a HOPE-like configuration model were made in a transonic wind tunnel. As a result, a wing bending-torsional mode flutter occurred in anti-symmetric mode. It was observed that the flutter occurred at lower dynamic pressure in the case of elastic support for roll than in the roll-free case. This type of flutter was confirmed by numerical analyses with the unsteady aerodynamic forces by DPM (Doublet-Point Method).
