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.

A landing pad system for a vehicle for controlling G-loading resulting from an impact landing with a landing surface in transverse directions, said landing pad system comprising: landing strut members disposed circumferentially about a central longitudinal axis of a base on a vehicle; first energy absorbing means attached to each strut member and including a rod member and friction elements in engagement with an upper portion of said rod member for absorbing energy upon relative movement between said friction elements and said rod member, said rod member having a longitudinal stroking axis in a first alignment with respect to said central longitudinal axis for absorbing impact energy in a first direction relative to said vehicle; a landing pad housing attached to each rod member, said landing pad housing having a bottom surface for engaging a landing surface; second energy absorbing means disposed in said housing about a lower portion of said rod member and including a slidable mounting of said lower portion of said rod member relative to said housing for movement independent of said first energy absorbing means and further including energy absorbing elements disposed about said lower portion of said rod member for absorbing impact energy in a second direction transverse to said stroking axis upon relative movement between the lower portion of the rod member and said housing.
