Abstract: A stabilization system for a towed aerodynamic body 1. The body is provided with two, contra-rotating tubular shrouds 3, 4 each fitted with a set of vanes 5, 6. When the towed body is disturbed by the towing aircraft's wake, the gyroscopic inertia caused by rotation of the shrouds exerts a damping effect on the subsequent oscillatory motion of the towed body. In one embodiment, the shrouds are coupled by wheels which constrain the shrouds to rotate in opposite senses. Hence gyroscopic precession effects due to each rotating shroud cancel.

Abstract: An aircrew support system for supporting a pilot's head, and optionally his torso, during high g maneuvers, enabling him to maintain his head in an upright position and thereby increasing his awareness of the situation at all times outside the cockpit comprises at least one head support line (3) adapted for connection between the pilot's head/helmet (4) and the seat (1), accelerometers for measuring the g force acting on the pilot/aircraft and a tension structure for applying a continuously variable tension to said support line of a magnitude determined by the magnitude of the current g force acting on the pilot/aircraft. The support system may include a restraint system, for restraining the pilot in a predetermined position during ejection and for disconnecting the support line on ejection.
