Abstract:

This invention relates to a hard landing indication system that will provide a quantitative assessment that a hard landing did or did not occur at the last landing of an airplane. A hard landing can cause structural damage to an airplane. An airplane that has been declared to have a hard landing must be grounded until an inspection of the structure has been made to determine if repairs are required.

Appl. No.:

6/333114

Inventors:

Ronald L. Cox - Long Beach CA

Assignee:

McDonnell Douglas Corporation - Long Beach CA

International Classification:

B25G 300
F16D 100
F16G 1100

US Classification:

403 27

Abstract:

A fail-safe zero-load hinge or pivot-joint having a first load primary support path comprising a sleeve and nut combination and a secondary or redundant load support path comprising a shaft, sized to be inserted axially through the sleeve with diametrical clearance, for threaded engagement with a nut providing axial clearance from said primary members. The secondary shaft and nut combination holds the joint intact after the primary load members have failed permitting the joint assembly to perform its normal designed function of load carrying with the continued full range of movement without the risk of restricted operation seizure or jamming. A locking cap is provided for simple, safe holding of the nuts of primary and secondary member from disengagement, or even partial back off. A dye indicator may be used to indicate failure of the primary load carrying members.
