During the re-entry of a spaceplane, it is necessary to use a Reaction Control System (RCS) for attitude control augmentation in flight regions where the control surfaces are not fully effective. A shock tunnel experiment was performed on aerodynamic interference induced by RCS jets in hypersonic flow to establish test techniques and to clarify the basic characteristics of aerodynamic interference of a delta-winged spaceplane with tip-fins. The results indicate that the effect aerodynamic interference on attitude control should be taken into account in the aerodynamic design of a spaceplane.
