Abstract
A device for introducing an air flow into a submarine, including a first duct which is fixed relative to the hull of the submarine and a second duct which is telescopically movable relative to the first duct, for emerging from the water with its upper end and allowing the air above to be sucked in while the submarine is running at periscope depth, the first and second ducts being in fluid connection with air sucking means and being at least partly housed in a tower of the submarine.

A device for introducing an air flow into a submarine, comprising a first duct which is fixed relative to the hull of the submarine and a second duct which is telescopically movable relative to the first duct, for emerging from the water with its upper end and allowing the air above to be sucked in while the submarine is running at periscope depth, said first and second ducts being in fluid connection with air sucking means and being at least partly housed in a tower of the submarine, comprising an aeraulic machine operating along one of said first or second ducts, said aeraulic machine being designed to at least partly compensate for pressure losses in the air flow passing through at least said second duct.
A method for managing the air flow introduced into a submarine through a snorkel whose upper end emerges from the water, comprising the steps of:
- preparing an aeraulic machine acting on said snorkel,
- detecting along said snorkel at least one of either the flow rate or pressure values of said flow,
- adjusting at least one operating parameter of said aeraulic machine depending on said value detected.
