DIRECTIONALLY CONTROLLABLE FLYING VEHICLE AND A PROPELLER MECHANISM FOR ACCOMPLISHING THE SAME
First Claim
1. A rotating flying vehicle comprising:
- a hub having an outer perimeter;
an outer ring having a diameter greater than said outer perimeter defined by the hub;
a plurality of hub blades extending outwardly and downwardly connecting the hub to the outer ring;
a main propeller has a pair of propeller blades extending outwardly from a central base section, a propeller control mechanism is secured to the central base section and is connected to a drive shaft extending from the hub, wherein the main propeller extends from the drive shaft beneath said plurality of hub blades, the main propeller when spinning will cause the vehicle to sufficiently rotate such that the vehicle will fly;
a system for determining a directional point of reference for the main propeller when the vehicle is rotating; and
the propeller control mechanism using a cyclic driving torque to fly the vehicle in a specified direction relative to a remote user, the propeller control mechanism includes a link connecting an edge of the central base to a lower section of the propeller control mechanism, and wherein the edge of the central base is in an offset position from the lower section of the propeller control mechanism, the lower section of the propeller control mechanism is further rotatably engaged to the central base, and the propeller control mechanism further includes a spring positioned to return the lower section of the propeller control mechanism to its offset position, wherein a change in a driving torque of the propeller control mechanism causes the link and spring to change the pitch of the propeller blades.

Abstract
A flying vehicle in accordance to an embodiment of the present invention includes a main propeller and a propeller control mechanism for flying the vehicle. The main propeller includes a central base that permits the propeller control mechanism to be connected to the drive shaft. The propeller control mechanism includes a propeller hub and a lower hub with offset knobs that are connected by a link. A returning spring is sandwiched between the hubs and tends to return the hubs to the offset position when a change in a driving torque of the drive shaft causes them to move. The spring and link work in concert to change the pitch and height of the propeller blades while substantially unchanging the tip path plane of the propeller blades.
