Abstract: The effectiveness of randomly indexed randomly ejected decoys/aerobodies is improved by flying lifting glide instead of ballistic trajectories. Elements matching body contours are deployed to locate the neutral point above and behind the center of gravity. These elements are oriented to generate strongly cross-coupled forces and moments in pitch and yaw, provide favorable aerodynamic rolling moments and trim the configuration at positive lift. Various layouts are discussed. Means of achieving desirable stability levels, even at supersonic speeds, improve trimmed lift/drag ratios, minimize induced roll and inertial cross-couplings, etc., are also described.

Abstract: The invention extends the operational envelope of towed bodies at high altitudes and at high dynamic pressures. It features fins with large span/chord ratios, compactly stowed along the body surface, pivotally swept back with their chord broadside to the airstream. These fins generate high drag forces and large stabilizing and damping moments, even at supersonic speeds. Sweepback angles, controlled by elastic restraints, increase as fin loads increase. This minimizes variations in cable tension, even in maneuvers. Fin drag forces can also extend telescopic body elements. Fin settings can also generate vertical or lateral forces to bias decoy position.
