Slide door device for aircraft

A slide door device for an aircraft includes an upper guide roller at a tip end of an upper arm provided at an upper part of a slide door and a lower guide roller at a tip end of a lower arm provided at a lower part of the slide door that are rollably engaged with an upper guide rail and a lower guide rail that are fixed along an upper edge and a lower edge of a door opening frame formed in a fuselage of an aircraft, respectively. An intermediate guide roller, provided at a tip end of an intermediate arm provided in a door opening, is rollably engaged with an intermediate guide rail that is fixed to an inner surface of the slide door, while smoothly guiding the slide door with the upper guide rail, the lower guide rail, and the intermediate guide rail.

Blade for vertical shaft windmill and lift type vertical shaft windmill having the same

The present invention provides a blade for a vertical shaft windmill capable of easily suppressing the excessive rise of the rotating speed of the windmill by a simple mechanical structure when the rotating speed rises beyond a prescribed value when wind is blowing at a high velocity and a lift type vertical shaft windmill having the blade. This blade (1) comprises an air brake (2) and a bearing (3) mounted on the trailing edge side thereof from the gravity center of the air brake (2). The air brake (2) is rotatably mounted in the blade (1) through the bearing (3). Also, a spring receiving plate (6) of roughly S-shape is mounted on the front inner surface of the air brake (2). The spring receiving plate (6) is largely projected forward of the air brake (2) and energized by a spring material (7) stored at the front part of a wind receiving chamber (12). When the rotating speed of the windmill rises beyond the prescribed value, the leading edge side of the air brake (2) is projected from the surface of a wing by a centrifugal force, and the trailing edge side of the air brake (2) is sunk from the surface of the wing. Accordingly, since an air resistance producing part is formed, the rise of the rotating speed of the windmill can be suppressed.
