DIRECTIONALLY CONTROLLABLE FLYING VEHICLE AND A PROPELLER MECHANISM FOR ACCOMPLISHING THE SAME |
摘要 |
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.
