Structure for supporting and guiding a hoistable mast of a submarine vehicle

A submarine vehicle comprising a structural part configured to receive at least one hoistable mast, said submarine comprising an assembly of a hoistable mast of a submarine vehicle and a support and guidance structure, wherein:

• the support and guidance structure comprises a support equipped with a guidance device for guiding the mast in translation in a raising direction, said support comprising a central wall, generally flat, extending longitudinally parallel to the raising direction, and delimiting a housing for the mast,
• the guidance device comprises at least two guide rails, borne by the support, extending in the raising direction, to operate in tandem with at least two guidance elements, borne by the mast and each of the at least two guidance elements operating in tandem with one of the at least two guide rails, whereby each of the at least two guide rails form stops for the related guidance element that operates in tandem with one of the at least two guide rails, suited to immobilize the related guidance element in a second direction perpendicular to the raising direction and perpendicular to the central wall, and
• the support and guidance structure comprises a fixation device configured to fix the support to a structural part of the vehicle,
• the guidance device comprises at least one other guide rail, borne by the support, to operate in tandem with at least another guidance element, borne by the mast and operating in tandem with the at least one other guide rail, whereby said at least one other rail forms stops for said at least another guidance element, suited to immobilize said at least another guidance element in a third direction perpendicular to the raising direction and the second direction, and
• the housing is open in the second direction, on all planes that are perpendicular to the raising direction,
• and wherein the mast bears:
• the at least two guidance elements in addition to the two guide rails, each operating in tandem with a respective guide rail, such that each guide rail forms the stops for the related guidance element, immobilizing the related guidance element in the second direction, and
• the at least another guidance element in addition to the at least one other guide rail, operating in tandem, whereby the at least one other rail guide forms stops for the other at least another guidance element, immobilizing the at least another guidance element in the third direction, and
• the support is affixed to the structural part via the fixation device,
• and wherein the structural part further comprises:
• a central bulkhead opposite which the central wall of the support is arranged,
• two lateral bulkheads extending perpendicularly to the central bulkhead, such that the structural part has a U-shaped horizontal cross section;
• and
• two ledges, each extending a respective lateral bulkhead, folded substantially parallel to the central bulkhead, such that the structural part envelops the support.
