THE DYNAMICS AND AERODYNAMICS OF SELF-SUSTAINED LARGE ANGLE OF ATTACK BODY SPINNING MOTIONS

Abstract

Several aerodynamic mechanisms, which will sustain large angle of attack body autorotative motions, are examined. It is shown that auto rotative motion can result in a very large drag force, which may significantly aid missile and booster recovery. A linear theory, which satisfactorily predicts the near-steady-state auto rotative spin characteristics of quasi-axi-sym metric bodies, is presented. The initiation of body autorotative motions under both low altitude and re-entry environments is investigated by a special six-degrees-of-freedom trajectory program. The aerodynamic characteristics of cylinder shaped bodies at angles of attack near 90 degrees are discussed.
