Abstract : An aircraft container delivery system is described. An ejector frame is positioned forward of a pair of rows of cargo containers to push the containers out the rear opening of an aircraft. An extraction line connects an extraction parachute to an extractor mechanism, upon which the ejector frame is attached, to provide the extraction force. The extraction mechanism includes base plates attached to the ejector frame. To the base plates are attached a rotatable clevis hook and a shock strut. The rotatable clevis hook holds a clevis on the end of the extraction line. The shock strut connects the base plates to a tow bar. The tow bar includes a latch that secures the clevis hook in position to hold the clevis, a pair of rotatable strike arm fingers and a draw bar hook. A stirrup gate mechanism is mounted at the rear of the aircraft and holds the extraction line beneath the containers as the ejector frame is pulled rearward. When the ejector frame and ejector mechanism reaches the stirrup mechanism, the strike arm fingers rotate over a strike arm to push open a pair of strike arms and open the gate to free the extraction line. The draw bar hook strikes the stirrup bar to stop the draw bar. The kinetic energy of the still rearward moving ejector frame breaks loose the clevis hook from the clevis to disconnect the extraction line. The shock strut absorbs the remaining kinetic energy of the ejector frame. Keywords: Patents, PAT-CL-244-137.3, Air drop operations. (KR)
