Abstract

A launching tube accommodates sonobuoys of differing lengths for individually launching the sonobuoys. Compressed gas modules located between the sonobuoys are individually activated by electrical signals to expel respective sonobuoys from the launching tube. Electrical contacts on the modules engage electrically conducting guides on the inner surface of the launching tube whereby the electrical signals are communicated individually to respective ones of the modules.

Claims

1. A launcher comprising:

a launching tube having longitudinal electrical conductors therein, said launching tube having longitudinal guides therein;

means positioned along a wall of said tube for locating buoys therein, each of said buoys having means for slidably contacting said guides for orienting said buoys about an axis of said tube, said contact making slidable electrical contact with one of said conductors; and

a set of firing modules positionable within said tube in alternating locations with said buoys, each of said firing modules being coupled to one of said contacts for contacting a specific one of said longitudinal conductors to permit individual activation of said firing modules in response to electrical signals coupled via said electrical conductors.

2. A launcher according to claim 1 further comprising means coupled to said longitudinal conductors and responsive to a series of electrical signals for sequentially triggering individual ones of said firing modules in response to successive ones of said electrical signals, and wherein said longitudinal electrical conductors are located within said longitudinal guides to permit said contacts to be guided by said guides as said contacts make electrical contact with said conductors.

3. A launcher comprising:

a launching tube having longitudinal electrical conductors therein;

a set of stops positioned in a wall of said tube for locating buoys therein;

a set of firing modules positionable within said tube in alternating locations with said buoys, each of said firing modules having an electrical contact for contacting a specific one of said longitudinal conductors to permit individual activation of said firing modules in response to electrical signals coupled via said electrical conductors;

means coupled to said longitudinal conductors and responsive to a series of electrical signals for sequentially triggering individual ones of said firing modules in response to successive ones of said electrical signals; and

a cover at and end of said tube, said cover providing access to said longitudinal conductors and plug means for contacting said longitudinal conductors via said cover for shorting said conductors together to insure deactivation of said firing modules.
