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.
