Helicopter with tubular steerable tilted body - has pivoted rotor blades for steering vertical body into flight attitude

摘要

The helicopter especially a helicopter which is tilted into the flight path has two counter rotating, coaxial rotors with blades for lift and propulsion. The angle of altitude change is derived from rotor blade movements. Each rotor has a hub with radial arms which carry profiled blades which are rotated to required adjustment angle. The helicopter axis is formed from tubular body which supports the rotors and the power transmission and helicopter steering elements are held outside the tubular body. The seats for the pilot and passengers are arranged with the backs parallel to the blades and the ground and offset from one another.
