FIELD: transportation. ^ SUBSTANCE: airborne vehicle comprises two flapping wings, a drive of their horizontal and vertical motion, cranks and gear wheels with identical number of teeth. The wings axles are fixed at their appropriate attachments fitted on the shafts. The shafts are clamped in fast cardan joints so that they can swing without axial rotation and axial displacement. Note that the shafts penetrate through the bushes fitted on the cranks, the latter being fastened on the rods passing through the gear wheel shafts to run aligned with them. Rods with cranks can move along the gear wheel axes, the bushes traveling along the shafts. The device additionally incorporates recoil springs to keep up the cranks with rods in their initial position. ^ EFFECT: simpler design and wider versatility. ^ 2 cl, 1 dwg |
