Abstract

A dual point suspension implement or apparatus adapted to be secured to a licopter or the like having a single point external loads attachment hook so as to support an external load by means of two suspension lines spaced longitudinally from one another. The dual point suspension implement comprises a carriage support secured to the aircraft forward of the aircraft hook, the carriage support extending laterally and comprising a curved track member having its radius of curvature substantially coincident with the pivot axis of the aircraft hook. The implement further comprises a carriage having a plurality of rollers which are engageable with the curved track whereby the carriage is free to move or swing along the curved track in arcuate fashion so that the implement together with the load is free to swing relative to the aircraft about the pivot axis of the aircraft hook. The implement further includes a main body extending longitudinally of the aircraft below the support structure. The main body is engageable with the aircraft hook and further has two external load suspension points spaced from one another with the aircraft hook being intermediate the external loads suspension points. The main body of the implement further has a portion at the front thereof for engagement with the carriage, this carriage engagement portion, upon selective actuation of the main aircraft hook for jettisoning, permitting the main body to swing downwardly from a load carrying position to a release position in which the carriage engagement member cleanly separates from the carriage allowing the main body and any external load carried thereby to fall free of the aircraft.
