A method and apparatus provided for monitoring the integrity of a structure (10) disposed in an environment containing a fluid (F) at an ambient pressure. The structure (10) includes a skin (12) and a plurality of internal cavities (14). The method involves applying a further fluid to the cavities (14), the applied fluid being at a pressure which is marginally greater than the atmospheric ambient pressure (F). The flow rate of the applied fluid is monitored for detection in a change in the flow rate. The change in flow rate is indicative of additional fluid seepage through the structure (10) providing advance warning of a failure in the integrity of the structure (10). Monitoring is achieved by passing the applied fluid through a high fluid flow impedance (28) and monitoring for a change in pressure across the impedance (28) using a transducer (30).

L'invention concerne un procédé et un appareil permettant de contrôler l'intégrité d'une structure (10) placée dans un environnement contenant un fluide (F) à une pression ambiante. Cette structure (10) comprend une enveloppe (12) et une pluralité de cavités intérieures (14). Ce procédé consiste à appliquer un autre fluide à ces cavités (14), le fluide appliqué étant à une pression légèrement supérieure à la pression ambiante atmosphérique (F). Le débit du fluide appliqué est contrôlé pour détecter un changement de débit. Le changement de débit est indicatif d'une infiltration de fluide supplémentaire à travers la structure (10), et ceci constitue un préavis d'alerte de la défaillance de l'intégrité de la structure (10). On effectue le contrôle en faisant passer le fluide appliqué à travers une impédance de débit de liquide élevée (28) et en contrôlant un changement de pression à travers l'impédance (28) au moyen d'un capteur (30).
