SYSTEM OF TWO COAXIAL MAIN ROTORS OF FLYING VEHICLE

摘要

aeronautical engineering; main rotors of flying vehicle. SUBSTANCE: proposed system includes reduction gear with two coaxial shafts, main rotor hubs, main rotor control circuits, two wobble plates and main rotor collective and differential pitch control mechanism. Shaft of upper main rotor is made axial downward motion bringing the lifting system to initial position without any adjustment. EFFECT: reduced overall size in height of coaxial helicopter both in parking position and in transportation. 2 dwg
