Abstract: An aircraft armament mounting system includes an elongated support plank member which is longitudinally insertable transversely through the aircraft cabin area so that a central portion is disposed therein. The central plank portion is anchored within the cabin area, with opposite outer longitudinal portions of the plank projecting outwardly from opposite sides of the aircraft. Specially designed mounting structures are provided which permit selectively variable and oriented combinations of rocket launchers, 7.62 mm machine guns and 0.50 caliber machine guns to be removably secured to the outwardly projecting plank portions to provide the aircraft with a high degree of armament interchangeability and versatility.

Abstract: An aircraft armament mounting system includes an elongated support plank member which is insertable transversely through the aircraft cabin area so that a central portion of the plank is disposed within the cabin area and its opposite end portions project outwardly from the aircraft. This central portion is anchored to the aircraft, and outer tip portions of the plank are pivotable between extended and inwardly folded positions. A pair of rocket launchers are mounted on downwardly projecting support structures secured to the outer ends of the plank tip portions, the support structure having integral adjustment mechanisms which permit vertical and horizontal adjustment of the rocket launcher firing axes. Supported on the underside of the plank end portions, inwardly of the foldable tip sections, are a pair of machine gun pods supported on specially designed shock absorbing gun mounts which carry a pair of machine guns provided with electrically driven charging assemblies.

Abstract: A retractable aircraft step module comprises a streamlined fairing having a recess for receiving a retractable step member which is connected to the fairing by spaced apart pivot links which together with the step member and the body member form a four bar linkage. The linkage includes a deflectable pivot connection between one of the links and the step member which provides a biasing force to maintain the step member in the retracted position. The deflectable pivot connection is provided by a pivot beam mounted on the step member and including a counterdeflection adjustment for preselecting the maximum biasing force. The step member and the fairing are adapted to mount on the exterior of an aircraft fuselage and are preferably constructed of reinforced plastic.
