Abstract
A landing pad system for absorbing horizontal and vertical impact forces upon engagement with a landing surface (15) where circumferentially arranged landing struts (12) respectively have a clevis (24) which receives a slidable rod member (13) and where the upper portion of a slidable rod member is coupled to the clevis by friction washers (30,32) which are force fit onto the rod member to provide for controlled constant force energy absorption when the rod member moves relative to the clevis. The lower end of he friction rod is pivotally attached by a ball and socket (44) to a support plate (42) where the support plate is arranged to slide in a transverse direction relative to a housing which contains an energy absorption material (50) for absorbing energy in a transverse direction.
