Abstract

An aircraft ejector release unit (E.R.U.) is provided in which ejection is accomplished by a pair of angularly moving ejection arms carrying pivotal thrust pads and both mechanically actuated by a common gas-operated piston-and-cylinder unit. The gas piston operates a crank that turns a central lever assembly coupled by actuating rods to rotate triangular cranks disposed near opposite ends of the E.R.U. Control links pivotally mounted at their upper ends on the E.R.U. body are pivotally connected at their lower ends to the ends of the ejection arms, and when the triangular cranks are rotated the ejection arms are extended by unfolding of the ejection arms and the control links, there being a pivotal connection between each crank and the respective ejection arm at a location intermediate the ends of the arm. Before the ejection arms extend, initial movement of the central lever assembly unlocks store suspension hooks of the self-releasing, sear type. Provision is made for bolting-on crutch arm modules at the ends of the E.R.U.
