Abstract:

An ejector arrangement for aircraft store racks that are carried by military type aircraft and the like for releasably attaching to the aircraft stores such as conventional or nuclear weapons, in which the ejector arrangement is duplicated in mirror image form at the usual fore and aft positions of the rack, with each ejector arrangement being in the form of an elongated housing with which the usual fore and aft sway braces are respectively integral, which ejector housing internally defines an elongate internal chamber in which are mounted an outer cylinder and inner cylinder that in the dormant relation of the ejector are in substantially telescoped coaxial relation with like ends of same disposed adjacent one end of the housing to which the rack ballistic gas is supplied, with the ejector cylinders at their other ends being exposed externally of the other end of the housing and keyed for sequential movement to their extended relations under the action of the ballistic gas involved, to thrust the store which at the same time has been released from the aircraft, beyond the aircraft's air stream envelope; the inner and outer cylinders of the rack ejectors, in moving from the ejector dormant relation to the ejector extended relation, act under the ballistic gas pressure released within the respective rack ejectors, to apply to the store the needed unbalanced force, and in a more or less uniform, sequential manner, to effect application to the store of maximized release thrust during the thrust stroke of the rack ejectors.
