1. A dual-state propulsion aircraft, comprising:
a) an aircraft fuselage; and
b) at least one dual-state propulsion system, which comprises:
a fixed nacelle, which is connected to the aircraft fuselage;
a rotatable nacelle, which is rotatably connected to the fixed nacelle;
a motor, which is connected to the rotatable nacelle, wherein the motor comprises a rotatable motor shaft, such that a motor shaft axis of the rotatable motor shaft is configured with a motor deviation angle between a nacelle pivot axis of the rotatable nacelle and the motor shaft axis in a range of 5-85 degrees; and
a thruster, which is connected to an outer end of the rotatable motor shaft;
such that the at least one dual-state propulsion system is rotatable to a first system position configured for vertical flight, such that a first shaft rotational direction causes a first direction nacelle counterrotation of the rotatable nacelle to a first nacelle position corresponding to the first system position, wherein the first direction nacelle counterrotation is induced by a first propeller torque of the thruster, wherein the first direction nacelle counterrotation is enabled by the motor deviation angle;
such that the at least one dual-state propulsion system is rotatable to a second system position configured for horizontal flight, such that a reversal of the first shaft rotational direction to a second shaft rotational direction causes a second direction nacelle counterrotation of the rotatable nacelle from the first nacelle position to a second nacelle position corresponding to the second system position, wherein the second direction nacelle counterrotation is induced by a second propeller torque of the thruster, wherein the second direction nacelle counterrotation is enabled by the motor deviation angle.
