Abstract : A multi-store launcher has each store in a stacked sequence releasably held by a swinging paddle assembly against the ejection force of negator springs. Each paddle assembly carries a burn resistor that is wired to maintain the paddles in a locked position. A pneumatic pulse from the transporting vehicle causes electronic circuitry to make the resistor fail, freeing the paddles to open away from the store and thereby allowing it to be ejected by the negator springs. The present invention discloses an electronically-actuated, multi-store dispenser wherein spring forces pushing against multiple burn resistor paddle assemblies cause sequential launching of stores from their tandem position inside a launch container. In some environments, it is desirable to dispense multiple stores from a launch vehicle, for instance sonobuoys, in dense patterns. Due to physical limitations of space in the dispensing vehicle, an effort was made to miniaturize the active components inside the store and therefore reduce the overall outer dimensions thereof. Once the size of the store was reduced, in order to meet the demands of the denser patterns, the inside of the individual launch containers were modified to allow each to hold and dispense more than one store.
