ABSTRACT:
An elongated support plank structure longitudinally extends transversely through the cabin area of a helicopter and has outer end portions projecting outwardly beyond opposite sides of the helicopter. A pair of 40 mm machine guns are mounted on the plank end portions and are supplied with belted ammunition from magazine boxes mounted on the plank within the cabin area via flexible feed chutes interconnected between the magazine boxes and generally V-shaped, interiorly rollered feed adapters interconnected between the outer ends of the feed chutes and the inlets of the machine gun feeder mechanisms. The 40 mm machine guns are secured to the outer plank end portions by specially designed mounting structures that may be selectively secured to (1) foldable tip portions of the plank structure pivotable relative thereto about horizontal hinge lines, (2) the hinge line portions of the plank when the foldable tip portions are removed, or (3) inboard gun mount stations disposed on the plank outer end portions inboard of the hinge lines. A 7.62 mm mini machine gun may be mounted on the support plank structure in addition to the two 40 mm machine guns.
