Abstract

This system for attaching a thermal battery to a flange of a power supply section of an underwater craft such as a torpedo of the type comprising a fixing sleeve (10) arranged around and fixed to the battery and provided with fixing lugs (11, 12, 13) comprising holes (14, 15, 16) for the passage of screws for attachment to the flange, is characterized in that the sleeve (10) is in the overall shape of a C, of which the intermediate part and the ends of the branches comprise the fixing lugs for fixing this sleeve to the flange.

Claims

1. A system for attaching a thermal battery to a flange of a power supply section of an underwater craft, said system comprising a fixing sleeve configured to be arranged around and fixed to the battery and provided with fixing lugs comprising holes for the passage of screws configured to attach to the flange, wherein the sleeve is in the overall shape of a C, of which an intermediate part and the ends of branches comprise the fixing lugs, wherein the fixing lugs are configured to fix the fixing sleeve to the flange.

2. The system according to claim 1, wherein the holes of the lugs of the C-shaped sleeve have a dimension larger than a diameter of the screws configured to attach the fixing sleeve on the flange.

3. The system according to claim 2, wherein the holes are oblong holes.

4. The system of claim 1, wherein said system is configured to attach a thermal battery to a flange of a power supply section of a torpedo.

5. A method of attaching a thermal battery to a flange of a power supply section of an underwater craft comprising attaching the system of claim 1 to said underwater craft.
