SONOBUOY DISPENSER SYSTEMS


DESCRIPTION

The SBDS is a lightweight sonobuoys dispenser family particularly suited for helicopter installation and is composed by a dispenser unit (SBDU) in the form of a vertical type, carousel based capable of carrying different types of NATO Sonobuoys (size A, G, X, F) that can be released by gravity either from a SMS command or a dedicated Control Panel or by an operator manual actuation.
The carousel, in three different version, stores up to 6, 8 or 10 Buoys maximum, in any pre-determinated combination. The Buoys are retained vertically in the Carousel by a lacth linkage system on the bottom and by a retaining adjustable cap on the top.


The carousel is rotated either CW or CCW by a dedicated mechanism as the selected Sonobuoy Launch Tube is positioned above a Launching Aperture. A manual rotating device is also provided to allow the carousel to release in case of motor failure or electrical power missing.
Monitoring switches control the position of the carousel and assure the positionig of the storing tube positioned over the dispensing hole. This aperture lines up with a dedicated hole in the HC floor enabling the Sonobuoy to drop by gravity when the release is actuated.
The release device can be opened by a SMS/CP command or by the Manual Release Pull Ring.

  PHYSICAL CHARACTERISTICS

  Dimmension (mm) Weight (Kg)
SDU/10 Ø 650 x 1300 < 30 KG.
CP 180 x 154 x 180 < 3 KG.

The SBDU is re-loadable in flight and rotates from one tube to the next one between adjacent buoys stations in a time not exceeding 2 seconds.
The CP (or the Store Management System) displays the types of sonobuoys stored and sector engaged on the helicopter dispensing hole, operates the CW or CCW rotation command, releases the sonobuoys from the selected launch tube by means of a protected switch and displays the SBDS status (LCKD, FAIL, ON).

A depot level STTE is provided for Maintenance and Troubleshooting Purpose.
