Abstract

Abstract This invention is concerned with an ejector release unit for releasing and projecting a store from an aircraft. The unit comprises a pair of telescopic ejection guns for projecting the store from the aircraft and a releasable latching mechanism for supporting the store, having an inner pair of pivoted hooks located between the ejection guns which are swung from their operative positions by means of links controlled by a central toggle mechanism, and an outer pair of hooks located outside the ejection guns, each of the hooks being held in its operative position by a separate toggle linkage which is released by means of a link controlled from the central toggle linkage, which is so located in a lateral direction as to pass to one side of the respective ejection gun. Each of the separate toggle linkages are preferably braced in a position just past dead-centre and is released by turning one of the links through the dead-centre position by means of a short connecting arm fixed to the link in question and acted on by the link controlled from the central toggle linkage.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 164 words
In an ejector release unit for releasing and projecting a store from an aircraft, a pair of telescopic ejection guns for projecting said store from said aircraft and a releasable latching mechanism for supporting said store, said latching mechanism including an inner pair of hooks mounted for pivotal movement and located between said ejection guns and first links connected to said inner hooks for swinging them from their operative positions, a central toggle mechanism controlling said first links, and an outer pair of hooks mounted for pivotal movement and located outside said ejection guns, a second link connected to each said outer hook, each of said second links being connected to a separate toggle linkage to hold each of said outer hooks in its operative position, each of said separate toggle linkages being controlled by said central toggle mechanism and each of said second links being so located in a lateral direction so as to pass to one side of said respective ejection gun.
Claim 2
Dependent Claim 164 words
In an ejector release unit for releasing and projecting a store from an aircraft, a pair of telescopic ejection guns for projecting said store from said aircraft and a releasable latching mechanism for supporting said store, said latching mechanism including an inner pair of hooks mounted for pivotal movement and located between said ejection guns and first links connected to said inner hooks for swinging them from their operative positions, a central toggle mechanism controlling said first links, and an outer pair of hooks mounted for pivotal movement and located outside said ejection guns, a second link connected to each said outer hook, each of said second links being connected to a separate toggle linkage to hold each of said outer hooks in its operative position, each of said separate toggle linkages being controlled by said central toggle mechanism and each of said second links being so located in a lateral direction so as to pass to one side of said respective ejection gun.
Claim 3
Dependent Claim 62 words
An ejector release unit according to claim 1, in which each of the separate toggle linkages is braced in a position just past dead-centre and is released by turning one of the links through the dead-centre position by means of a short connecting arm fixed to the link in question and acted on by the link controlled from the central toggle linkage.
