Abstract

Multi-stage reduction of impact forces are disclosed. An example apparatus to reduce impact energy of an aircraft during landing includes a rotatable landing leg having a proximal end near an axis of rotation and a distal end opposite the proximal end, a first flexible portion of the proximal end, where the first flexible portion is to engage a first engaging portion at a first rotation angle of the rotatable landing leg, and a second flexible portion of the distal end, where the second flexible portion is to engage a second engaging portion at a second rotation angle of the rotatable landing leg.
