FLIGHT VEHICLE WITH FLAPPING WINGS ('DRAGONFLY')

摘要

FIELD: aircraft engineering.;SUBSTANCE: proposed flight vehicle comprises airframe accommodating engine with reduction gear and two crank drives. The latter serve to drive two power shafts, which make, via chain drives, four symmetric wings waving. Aforesaid wings incorporate mechanism designed to allow wings to rotate about lengthwise axis. Said mechanism is arranged in the wing root on central spar mounted in yoke to revolve therein when wings flap driven by two ratchet-and-pawl gears. Each of said gears consists of two disks, one attached onto wing spar and another represents a pulley with pawl, and is furnished with control lever.;EFFECT: higher stability and better controllability.;2 dwg
