A REVIEW OF SOME RECENT PROGRESS IN UNDERSTANDING CATASTROPHIC YAW
Abstract
Catastrophic yaw and roll lock-in are studied at supersonic and subsonic speeds. Roll lock-in is found to occur on isolated fins and is traced to a leading edge vortex. Free rolling motions are found to be accurately represented by the roll lock-in theory. Catastrophic yaw is observed in three- degree-of-freedom and six-degree-of-freedom wind tunnel tests. Mass asymmetry in a 10 degree cone is found to cause rolling velocity, roll lock-in, and catastrophic yaw.
