The loss of airplanes and occupants attributable to departures from controlled flight and ensuing spins has been a problem since the earliest days of aviation. These losses have plagued both the military and general aviation communities. The phenomena responsible for such losses take on added significance because, in the past ten years, high angle-of-attack capability in the post-stall region has been shown to significantly enhance the air combat maneuvering effectiveness of fighter airplanes and, therefore, this is not a region to be avoided, but rather exploited, if possible. Fortunately, the aerodynamic characteristics that produce departures and spins have been identified within the past few years through rotary balance tests, which identify an airplane's aerodynamic characteristics in a steady rotational flow environment. It was demonstrated in the Phase I that the high angle-of-attack aerodynamic characteristics are very configuration dependent and that forebody geometry can have a significant influence on these characteristics. In the extreme case, an aircraft's undesirable aerodynamics can be completely attributable to the forebody. In this instance, autorotative yawing and rolling moments, as well as increasing nose-up pitching moments with increasing rotation rate, are realized.
