Abstract
A method and apparatus for extracting water droplets from a water-laden airstream includes introducing the airstream into an extractor duct, imparting a swirling motion to the airstream at a first axial location in the duct, removing water droplets from the airstream that have been thrown to the inner surface of the duct at a second axial location downstream of the first location, and at a third axial location downstream of the second location removing water droplets not removed at the second location. The water removal mechanism at the second location includes a first collection chamber and a first array of apertures circumferentially positioned about the duct and communicating the interior of the duct with the first collection chamber. The water removal mechanism at the third location includes a second collection chamber and an upstream-facing annular ring of smaller diameter than the diameter of the duct for capturing water droplets that have not been collected by the water removal mechanism at the second location.
