The invention relates to a wing skeleton and manual transmission device of bird-imitating manual flapping-wing flight, and belongs to the field of manual bionic flapping-wing aircrafts. According to the device, a wing skeleton, a hand and foot transmission device and a rectangular back frame are combined together; and an inner wing skeleton and an outer wing skeleton of a wing are composed of two groups of special torsion springs. A group of spring handles serving as a manual device are fixedly connected to an inner arm of the torsion spring of an inner wing; both hands are sleeved on the handles and make left-and-right motions to flap the wings; the torsion spring of an outer wing is sleeved on a vertical bar at the tail end of an outer arm of the torsion spring of the inner wing; and the inner arm of the torsion spring of the outer wing is fixed on a transverse bar of the outer arm of the inner wing through the vertical bar. When the outer wing uplifts, the outer wing naturally hangs down to form a certain angle due to a specially set elasticity coefficient of the torsion spring, thereby reducing the resistance of the wing uplift. Meanwhile, a digging rope passing through a pulley sleeved on the spring handle, the knees and the feet in turn is arranged so as to enhance flapping force of the wing by pedaling the digging rope with feet. The reliable and efficient wing skeleton and manual transmission device are provided for bird-imitating manual flapping-wing flight.

The invention discloses a manpower bird-imitating aircraft, and belongs to the technical field of bionic aircrafts. The aircraft comprises flapping wings, a hang glider, a rack, a left support, a right support, a synchronizing mechanism, a pedal driving mechanism and an undercarriage, the flapping wings are located on the two sides of the rack and can generate vertical flapping and pitching rotation relative to the rack, the hang glider is located above the rack and hinged to the rack through the left support and the right support, the middle of the hang glider is hinged to the rack, and the tail of the hang glider is hinged to the left support and the right support through connecting rods, the flapping wings on the two sides of the rack are driven by the pedal driving mechanism and the synchronizing mechanism to synchronously flap up and down to generate lifting force and advancing thrust, and the left support and the right support are manually operated to change the pitch angles of the flapping wings and the hang glider to achieve maneuverability control over flight. The manual bird-imitating aircraft provided by the invention can give play to the characteristics of large leg strength and flexible arms of people, is high in flight reliability, and has a very good application prospect in the aspects of high-rise escape, recreational activities, physical exercises and the like.
