    Abstract: An inlet barrier filter system for a tiltrotor aircraft comprising a filter duct extending from a filter to a filter outlet, a ram air duct extending from a ram air inlet to an engine where the filter duct connects to the ram air duct at the filter outlet, and a closure member movable between a first position blocking the ram air duct and a second position blocking the filter outlet. In use, the inlet barrier filter system provides for two mutually exclusive air flow paths, one for introducing ram air to the engine while closing off the filter and another air flow path for introducing filtered air to the engine while closing off the ram air duct.

    Abstract: An adhesive joint for an aircraft includes a first aircraft component having a first surface forming one or more isolation grooves, a second aircraft component having a second surface and an adhesive forming a bondline between the first and second surfaces to bond the first aircraft component to the second aircraft component. The adhesive substantially fills the one or more isolation grooves to form at least one disbond arrest boundary. The at least one disbond arrest boundary is operable to prevent a disbond in the bondline from traversing therethrough, thereby preventing the disbond from propagating along the bondline across the at least one disbond arrest boundary.
