Abstract: A multi-store launch container is disclosed wherein a plurality of stores, aintained in a tandem configuration therein, can be sequentially ejected. The container is normally carried by a vehicle and receives the necessary charges, of for instance pressurized gas, at its breach end. A spring-biased cocking mechanism forces open a first port cover and maintains a second port cover in the closed position. After the first charge is fired, the cocking mechanism allows the port covers to pivot and the first port is now tightly shut and the second port open for the next charge.

Abstract: A pneumatic launch system for an aircraft for ejecting one at a time a pllity of sonobuoys within each of a multiple array of tubes. A compressed air supply from the aircraft is regulated in a plenum selectively having poppet valves for selectively releasing plenum air to each sonobuoy within a tube. Each poppet valve is held against the outlet port by differential gas pressure across a piston connected to the valve. A quick exhaust valve bleeds the air from one side of the piston causing it to open and allow the plenum air to pass through the port and apply an ejection force to a sonobuoy. When the exhaust valve is closed, the pressure on either side of the piston equalizes and the poppet valve closes. A replenishment poppet valve recharges the plenum when the pressure drops below a regulated level.

Abstract: A pneumatic restraint and ejection system for a multiple sonobuoy launcher aving a single plenum communicating through separate clack valves to the inboard ends of a plurality of launcher tubes and through separate girdle valves to inflatable girdles about the launch tubes. After sonobuoys are inserted into the launch tubes, the plenum is charged with compressed air with the clack and girdle valves positioned to impart an ejection force on the backs and a longitudinal restraining force on sides of the sonobuoys. A sonobuoy is ejected by actuating the girdle valve to shut off the plenum air to the girdle and to exhaust the air in the girdle. As the sonobuoy leaves its launch tube, the air behind the sonobuoy expands causing a sudden differential pressure between the plenum and the tube to cause the clack valve to close and prevent loss of plenum pressure through the empty launch tube. In one embodiment, the launch tube includes a solonoid actuated latch at the discharge end which secures the sonobuoy therein.
