Manned and unmanned aircraft
A manned or unmanned aircraft has a main body with a circular shape and a circular outer periphery. One or more rotor blades extend substantially horizontally outward from the main body at or about the circular outer periphery. In addition, one or more counter-rotation blades extend substantially horizontally outward from said main body at or about the circular outer periphery, but vertically offset from the main rotor blades.
1. An aircraft comprising:
a main body having an outer periphery;
one or more blades rotating about the outer periphery of said main body to generate a thrust; and
one or more flaps pivotally coupled at said main body to rotate between a first position at which said one or more flaps avoid interference with the thrust, and a second position at which said one or more flaps at least partially engage the thrust.
2. The aircraft of claim 1 , wherein the thrust pushes downward on said one or more flaps in the second position to tilt the aircraft downward at said one or more flaps in the second position.
3. The aircraft of claim 2 , wherein said aircraft moves in the direction in which it is pushed downward by the thrust.
4. The aircraft of claim 1 , wherein said one or more flaps have an outer planar surface that in the first position is substantially parallel to the thrust direction, and in the second position is between 90-180 degrees to the thrust direction.
5. The aircraft of claim 1 , further comprising a drive assembly comprising:
a central shaft;
a blade mount rotatably coupled to said central shaft and coupled to said one or more blades;
a bearing fixedly coupled to said blade mount;
a platform fixedly coupled to said shaft;
a gear rotatably engaged with said bearing;
a motor or engine mounted to said platform and rotatably driving said gear to rotate said bearing, which rotates said blade mount and said one or more blades.
6. The aircraft of claim 5 , wherein each of said blade mount, bearing, platform and gear have a planar surface that are parallel to one another and orthogonal to a longitudinal axis of said central shaft.
7. The aircraft of claim 1 , further comprising one or more counter-rotation blades rotating about the outer periphery of said main body.
8. The aircraft of claim 7 , further comprising a drive assembly positioned between said one or more blades and said one or more counter-rotation blades.
