Submarine vehicle intended to measure data at the deep ocean sea- bottom

摘要

The invention is related to a submarine vehicle for the deep ocean research. This vehicle is composed of a penetrator (1) and of a support structure (2 to 7). The vehicle descends by gravity due to a ballast disposed in the lower part (11) of the penetrator. Apart from this ballast, the vehicle can be recovered due to a discoupling of the ballast by an explosive bolt (13). After discoupling, the float clusters (8) located in the upper part of said support structure supply the mounting thrust necessary for transferring the vehicle up to the ocean surface. If this thrust is insufficient, a pyrotechnical device (15) can be provided, which inflates a bag and thus creates an additional thrust directed to the upside.PPThe invention is particularly useful in the investigation at the deep ocean sea-bottom.
