A rotorcraft and method for providing controlled flight which provides
flight in all six degrees of freedom of pitch, roll, yaw, up/down,
forward/rear, and left/right. The rotorcraft includes a fuselage with a
pair of counter-rotating rotor blade assemblies each having a plurality
of radially-extending airfoil shaped blades about a vertically disposed
central axis. A rotor drive system mounted to the fuselage includes a
motor or engine for rotationally driving the rotor blade assemblies. A
rotor blade control system monitors the rotational location of each blade
relative to the fuselage and allows a pilot to control respective
vertical and horizontal thrust components of the blades corresponding to
lift versus drag characteristics of the airfoils during rotation about
the fuselage. This is done by changing the pitch angles of the blades
and/or by utilizing respective flaps pivotally mounted to the blades to
change the effective pitch angle of the blades.
