Proposed footpad assembly supports structure, also absorbs impact energy in both horizontal and vertical directions. Resists impact deformation with approximately constant force, unlike older impact devices. Designed to absorb more energy in given stroke and to protect structure from high peak shock loads. Assembly lightweight, compact, and easy to manufacture. Relies on friction to absorb kinetic energy in vertical direction and on crushable material to absorb kinetic energy in horizontal direction. Designed for specific maximum load, nearly independent of speed and angle of impact. Used in variety of single-impact applications; for example, on pallets dropped by parachute from airplanes.
