METHOD OF PRODUCING FLAPPING MOTION AND FLAPPING SCREW TO THIS END |
摘要 |
FIELD: transport.SUBSTANCE: invention relates to propulsors for air and water transport facilities. Method of producing flapping motion by blades of screw fitted on screw hub comprises combining blades revolution about hub axis and about their lengthwise axes. Said blades revolution about their lengthwise axes is effected indirection opposite that of hub rotation and at angular speed equal to that of hub. Flapping screw comprises blades with their lengthwise axes are set in one plane or intercrossed in parallel planes, or intercrossed in planes at crossing angles of 0 to 90 degrees. Proposed screw is equipped with intermittent drive to allow n blade additional turns per one hub revolution in or against hub rotational direction. Said screw may be equipped with extra mechanism for adjustment of blade inclination and/or medium flow guide device.EFFECT: higher efficiency.18 cl, 9 dwg |
