ABSTRACT:
A high energy absorbing aircraft tail skid assembly for protecting an aircraft fuselage lower skin portion from damage in the event of a tail strike due to over rotation on take-off of the aircraft. The high energy absorbing tail skid assembly is pivotally mounted to the aircraft bulkhead, and comprises a telescoping rod assembly including a crushable aluminum cartridge, positioned coaxially with respect to the central axis of the telescoping rods. The telescoping rod is coupled through linkage, including a fuse pin providing a predetermined failure mode for the high energy aircraft tail skid assembly, to prevent overloading critical aircraft structure.
