Abstract: A recirculating water extractor includes a swirl vane, a converging nozzle, and two sumps. The recirculating water extractor may be designed to reintroduce uncollected water droplets back into the air stream upstream of both sumps, which may provide additional opportunities for separation. The Coanda effect may be exploited to increase the discharge of water along a surface. Utilizing a converging nozzle may intensify the centrifugal force applied to the air stream rich with entrained water and may move more of entrained water into contact with the wall of the nozzle, which, in turn, may enhance the liquid/vapor separation compared to prior art water extractors. The recirculating water extractor utilizing the Coanda effect and the method for removing entrained water from an air stream may be suitable for, but not limited to, applications in the aircraft and aerospace industries, for example, by being included in environmental control systems of aircraft.

Abstract: An air prefilter is disclosed for use with internal combustion engine air filters of the type having replaceable filter elements. The prefilter has a perforated sleeve connected between the usual intake openings and the filter element of the conventional air filter. This perforated sleeve is enveloped by an open-pore foam filter medium, which is of such porosity that engine intake air primarily passes therethrough rather than through the intake openings of the conventional air filter. The prefilter prevents foreign matter and water vapor from reaching and blocking the conventional filter element, which blocking causes the engine to receive insufficient air for efficient combustion. When the prefilter medium is saturated or blocked with impurities, the conventional air filter operates as usual, until the prefilter medium is cleaned or replaced. An adjustable deflector helps prevent foreign matter from blocking the prefilter medium.
