Gyro/Heli V

Gyro/Heli V

Unified Gyrocopter & Synchropter (compound in future?)

Sketch:

Quick & dirty sketch.

Overview:

The preliminary design of a hybrid gyrocopter/helicopter (maybe also compound in future) with intermeshing rotors, that theoretically is easier and safer to fly;

Advantages:

Flies like a plane:

Symmetrical handling.
Fast forward speed; because of propeller and partially loaded rotor disk, plus potential for compound configuration.
Elevator controls longitudinal pitch, differential collective controls roll and rudder controls yaw. There is no cyclic rotor control.

Takes off & lands like a helicopter: Option of short field or vertical, takeoff and landing; depending on pilot's desire to use the collective lever or not.

Safety:

Pilot's controls are identical to those of a plane: Control stick for speed and lateral control, pedals for yaw and throttle for lift. A collective lever is available if desired for jump takeoff, vertical landing and engine-out landing.
Tail is at the end of a long moment arm.
Mass, thrust and drag are inline.
Propeller thrust location is farther forward than that of conventional pusher configuration.
Rotor Governor;

Automatic and constant maintaining of 100% operational RRPM.
Automatic lowering of blade pitch to autorotation setting upon loss of power.
Automatic raising of blade pitch before jump takeoff.

Power is automatically and constantly split 50/50 between propeller and rotor disks. Pilot only controls the throttle.

For more information on the above; see Gyro/Heli V Detail

Drawings:

Overall Conceptual Outline: The rotors and the propeller are located together, between the pilot and the engine.
