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.

In a store rack assembly having fore and aft store ejector mechanisms, the improvement where each ejector mechanism comprises: a telescoping assembly including an elongate housing defining an internal chamber extending longitudinally thereof and mounting in said chamber an outer cylinder and an inner cylinder within said outer cylinder, said chamber and said cylinders being in telescoped substantially coaxial dormant relation and said cylinders having like ends of same disposed adjacent one end of said housing, said housing being connected to a source of ballistic gas and including means for exposing said like ends of said cylinders to the ballistic gas when the source of the ballistic gas supplies the ballistic gas to said housing, said cylinders at their other ends being exposed exteriorly of the other end of said housing for movement to their extended relations therefrom, said housing at said other end including means defining a first lateral aperture and a second lateral aperture spaced from said first lateral aperture axially of said cylinders toward said other end of said housing, with said apertures being aligned circumferentially of said housing, said inner cylinder defining adjacent the other end of same an internal flange that substantially complements the internal diameter of said outer cylinder and is proportioned for substantially complementary sliding fit within said outer cylinder, and said inner cylinder defining an external recess thereabout adjacent said flange having a cam surfacing adjacent same in coaxial relation thereto, a first latch member interposed between said first lateral aperture and said inner cylinder surfacing and extending through an opening formed in said outer cylinder in the dormant mode of said telescoping assembly, said housing first lateral aperture including a cam surfacing that serves to bias said first latch member radially inwardly, when said like ends of said cylinders are exposed to the ballistic gas when supplied to said housing for actuating said telescoping assembly to move from said dormant mode thereof, for camming said first latch member into said inner cylinder recess when said inner cylinder flange is adjacent said outer cylinder other end, whereby said cylinders are then both keyed together for joint movement outwardly of said housing chamber axially thereof in the direction of the other ends of said cylinders under the pressure of the ballistic gas exposed to said like ends of said cylinders, with said outer cylinder at said one end thereof defining an annular flange proportioned for substantially complementary sliding fit within said housing chamber, and said outer cylinder being recessed adjacent said other end thereof in circumambient alignment with said second lateral aperture, a sleeve slidably mounted in said housing in circumambient relation to said outer cylinder said like end when said cylinders are in their dormant relation, said sleeve defining an internal recess thereabout intermediate said first and second apertures axially of the respective ejector assemblies, a second latch member interposed between said second lateral aperture and said outer cylinder and extending through an opening formed in said sleeve, said inner cylinder cam surfacing biasing said first latch member into said sleeve recess when said inner cylinder recess is aligned with said sleeve recess, whereby said sleeve is biased outwardly of said housing, said housing second lateral aperture including a cam surfacing that serves to bias said outer latch member radially inwardly, when said first latch member biases said sleeve for movement in said direction, for camming said second latch member into said outer cylinder recess, whereby said second latch member keys said sleeve to said outer cylinder for movement therewith in said direction therewith, said flange of said outer cylinder engaging stop means defined by said housing within said chamber thereof, to provide the extended relation of said cylinders under the bias of said ballistic gas.
