<p>In a landing gear for an airframe mounted on a cushioned strut, an airframe mounted portion is guided along a landing gear portion after the landing gear touches down. Crash attenuation is absorbed by a work absorbing tube secured at one end thereof to the airframe portion in an encircling relation with respect to the airframe portion. A work applying structural fitting is secured to the airframe at the other end of the work absorbing tube and is adapted to engage and work the tube as the airframe moves downward relative to the airframe portion to dissipate energy involved in arresting downward movement of the airframe. Coupling structure between the airframe and the airframe mounted portion is provided to fail at a predetermined load to permit movement of the airframe relative to the airframe portion.</p> |
