FLEXIBLE ELEMENT TO ENSURE FLEXING AND CHANGE ANGLE BLADES RIGID ROTORS

摘要

Elastic element that provides the flexion and changes of rotor blades angle, enables waving, tossing and rotation of helicopter or drones rotor. The novelty about this invention is a form and method of the beam (4, 5) construction (Fig. 1) that are diagonally positioned and crossed in the middle but arc not connected to each other.Specifically shaped beam (4) is rigidly attached at one end to the upper corner the shackle (3) and with its other end to the opposite upper corner of the shackle (2). Specifically shaped beam (5) is rigidly attached with one of its ends to the bottom of the shackle (3), diagonally from the connection between the beam (4) and the shackle (3), and with its other end to the bottom of the shackle (2) diagonally from the connection between the beam (4) with the shackle (2). Shaped and crossed in middle, beams (4, 5), that are not connected, provide necessary disavowal and waving of the blade (7). Diagonally connected beams (4, 5) on the shackles (2, 3) provide better torsion of the whole element and therefore more efficient change of rotor angle (7).
