  • Patent number: 4779824
    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.

  • Patent number: 4398686
    Abstract: A system for controlling the low altitude extraction of cargo from aircraft having a two part force transfer link assembly connected between drogue parachute and a main parachute. The link assembly is held in a tow-plate link release mechanism. The link assembly can be released by an electrical command signal from the aircraft cockpit or manually by a mechanical control system near the compartment bulkhead. The mechanical control includes a push-pull cable which operates the link release mechanism or which operates only a part of the link assembly to jettison the drogue parachute.

  • Patent number: 4052894
    Abstract: A dual pivoting vane having a miniature dual bead thermistor anemometer at its upstream extremity and with light beam angular position sensors on the pivot axes provides a sensitive velocity vector sensor for measuring both magnitude and direction of low velocity airflow relative to a three-dimensional reference space of the body carrying the velocity vector sensor.
