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 having a center shaft for connecting to a drive shaft extending from the hub, the main propeller having first and second propeller blades extending from the center shaft and positioned 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
a 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 further includes a first linkage connecting the center shaft to the first propeller blade and a second linkage connecting the center shaft to a region defined on the main propeller, wherein a change in a driving torque of the propeller control mechanism causes the first linkage and the second linkage to work in concert to change the pitch and height of the propeller blades while substantially unchanging the tip path plane of the propeller blades.

Abstract
A flying vehicle in accordance to an embodiment of the present invention includes a propeller control mechanism for flying the vehicle. The propeller control mechanism includes a propeller having a center shaft for connecting to the drive shaft; first and second propeller blades extending from the center shaft; and a control mechanism including a first linkage connecting the center shaft to the first propeller blade and a second linkage connecting the center shaft to a region defined on the propeller, wherein a change in a driving torque of the drive shaft causes the first linkage and the second linkage to change the pitch and height of the propeller blades while substantially unchanging the tip path plane of the propeller blades.

13. A propeller control mechanism to fly an object in a specified direction, having a motor for rotating a drive shaft, comprising:
-
a propeller having a center shaft for connecting to the drive shaft; first and second propeller blades extending from the center shaft; an open region surrounding the center shaft and extending to a region on the first propeller blade; and a control mechanism including a first linkage connecting the center shaft to the first propeller blade and having a portion thereof positioned in the open region, the control mechanism further including a second linkage connecting the center shaft to a region defined on the propeller, wherein a change in a driving torque of the drive shaft causes the first linkage and the second linkage to work in concert to change the pitch and height of the propeller blades while substantially unchanging the tip path plane of the propeller blades. - View Dependent Claims (14, 15, 16, 17)
