Embodiment Construction

[0035] While the present invention allows embodiments in different forms shown in several drawings, preferred embodiments of the present invention will be described in detail as follows. It should be understood, however, that the present disclosure is to be considered as illustrative of the principles of the invention only, and not as a limitation on the spirit or scope of the invention and / or the illustrated embodiments.

[0036] The aircraft shown in Figure 1 is only shown as a helicopter in one embodiment of the invention. As is typical for helicopters, the current embodiment includes a frame housing any electromechanical components as well as a chassis. Attached to the lower part of the frame 12 is a landing gear 14 so that the helicopter can rest on a given surface. The helicopter 10 includes a main propeller 20 and a directional propeller for correcting counter-rotation. Main propeller 20 and directional propeller 22 are powered by motorized means, discussed in detail ...

Abstract

A propeller related vehicle in accordance with one embodiment of the present invention is described as a helicopter having an airframe housing a motor mechanism for powering a main propeller attached to a main drive shaft that extends vertically through the airframe and for powering a tail rotor. The helicopter further includes a horizontal stabilizing mechanism attached between the main propeller and the main drive shaft, which permits the main propeller to freely pivot about the main drive shaft independently from the airframe. As such when the main propeller is rotating and the main propeller begins to pitch, the rotating main propeller has a centrifugal force created by the rotation thereof and will tend to pivot about the horizontal stabilizing mechanism in a manner that offsets the pitch such that the helicopter remains in a substantially horizontal position. In addition various main propeller configurations may be employed that provide additional self-stabilization.
