초록

A movable sheet overlying a wing is disclosed that creates laminar flow over its exposed surface. The movable sheet serves as an integral, retractable shield for protecting a suction support structure of a wing against contamination, and also serves as a movable, conductive substrate for deicing by means of electrical resistance or hot-gas heating. The invention includes a movable sheet that is mounted scroll-like on two motor-driven rollers. The sheet has a solid area without perforations that protects the suction support structure from contamination, a...

청구항

A movable sheet apparatus for covering a portion of a wing, wherein the apparatus comprises: roller means including a roller rotatably mounted within the wing and extending spanwise with respect to the wing; a movable sheet overlying the wing and extending scroll-like between and engaging the roller means, wherein the movable sheet is wrapped fully around the circumference of the roller; and means for rotating the roller means, including means for rotating the roller through multiple revolutions to move the movable sheet.
