DEVICE AND METHOD FOR PROTECTING A CRYOGENIC TANK AND TANK COMPRISING SUCH A DEVICE

摘要

Method for protecting a cryogenic tank, the tank (11) comprising two concentric casings (12, 13) between them delimiting an inter-wall space (14) in which a so-called low pressure obtains, the method involving: a step of detecting an impact on the tank (11) and/or an increase in pressure within the inter-wall space (14), characterized in that it involves a step of generating a stream of inert gas within the inter-wall space (14) only if an impact on the tank (11) of a determined intensity and/or a determined increase in pressure at the inter-wall space (14) is/are detected.
