ABSTRACT:
A mechanism for enabling an aircraft to carry and release a store featuring hanger. The hanger has a hollow portion which is formed with a circumferential inner recess. A circular spring ring with a diameter which is smaller than the diameter of the inner recess, is dimensioned to fit within the inner recess of the hanger and to fit completely within the inner recess when a sufficient outward radial force is exerted upon it. The mechanism further includes a cylinder which fits within the hollow portion of the hanger. When the portion of the spring ring engages the outer recess of the cylinder, the hanger and the cylinder, and, therefore, the store and the carrier, are securely connected to each other. A slidable plunger having wings near one of its ends is used for pushing the spring ring into the inner recess of the hanger. The mechanism includes a mechanism for bringing about the forceful sliding of the plunger toward the store so as to cause the wings of the plunger to force the spring ring radially outward into the inner recess of the hanger, thereby allowing the hanger to disconnect from the cylinder, and causing the store to separate from the carrier.
