초록 ▼

A normally collapsed but extendible nozzle exit cone for the second or upper stage of a missile having a first or lower stage includes three concentrically disposed linear segments each of which is a hollow, truncated cone larger than the adjacent upstream segment. The mechanism for translating the segments from their collapsed or stowed state to their deployed state includes a plurality of pneumatic cylinders, each of which contains a gas generant charge, and a set of folding linkages associated with each pneumatic cylinder that are attached to the movable segments of the exit cone. The segments of the exit cone are provided at their ends with locking shoulders and one shoulder of each pair includes an elastomeric seal so that gas tight seals are provided between the segments, as they are aligned. An over-center action of each of the folding linkages locks the extended exit cone adjacent thrust forces of the nozzle.
