Sliding Control Concept,

Abstract

SLIDING CONTROL CONCEPT WAS INVESTIGATED AS A POTENTIAL MEANS OF TRIMMING A HIGH-PERFORMANCE MISSILE WITH MINIMUM DRAG AND POWER PENALTIES. In this concept, control surfaces slide into the exhaust plume of an underexpanded jet and provide stabilizing or control forces by virtue of the flow field encountered in the jet. Experiments on a convenient sliding control configuration indicate that with jet off the force on the control surface is a direction and magnitude consistent with an elongation of the missile body. The forces imparted by an underexpANDED JET ACTING ON THE SLIDING CONTROL WOULD DEPEND ON THE POSITION OF THE CONTROL SURFACE WITH RESPECT TO THE JET AND ON THE JET PRESSURE. The jet-induced force was not particularly strong for the test configuration, but the scheme could apparently be employed to trim a missile, and, under some circumstances, might provide sufficient force for maneuver. Keywords: Missile control; Aerodynamic trim; Aerodynamic stability.
