Sonobuoy launcher system
First Claim
1. An improved launcher for restraining and ejecting a store contained therein, comprising:
- plenum means formed to receive a charge of compressed gas;
tube means formed to receive store in one end and connected to said plenum to receive said gas for urging the store out of said tube means, said tube means including an inflatable girdle means intermediate the ends thereof formed to receive compressed gas for longitudinally restraining the store; and
deflating means operatively connected to said girdle means for selectively depressurizing the gas therein, whereby the compressed gas in said tube means ejects the store.

Abstract
A pneumatic restraint and ejection system for a multiple sonobuoy launcheraving 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. Actuation of the solonoid simultaneously releases the latch and operates the girdle valve. In another embodiment, three sonobuoys are loaded in tandem within a single launch tube. Three pressure chambers and girdles are separately actuated by solonoid-actuated girdle valves for sequential ejection of the sonobuoys.
