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. The rotor blades and counter-rotation blades can be folded upward into a storage position. In addition, the unmanned aircraft can have solar panels positioned about the top housing and fuselage of the aircraft.
1. An aircraft comprising:
a main body having a circular shape with a circular outer periphery;
one or more blades extending substantially horizontally outward from said main body at or about the circular outer periphery, said one or more blades rotating with respect to said main body;
an annular gear located at or about the outer periphery and coupled to said one or more blades;
a motor configured to drive said annular gear to drive said one or more blades, wherein said motor is located directly adjacent the annual gear; and
a planet gear directly coupled to the motor to drive said annular gear.
2. The aircraft of claim 1 , further comprising a compartment located at an upper portion of said main body and a parachute housed in the compartment.
3. The aircraft of claim 1 , further comprising landing gear located at a bottom portion of the main body.
4. The aircraft of claim 1 , wherein the aircraft is a helicopter-type aircraft.
5. The aircraft of claim 1 , further comprising a jet engine configured to generate electricity for use by the motor.
6. The aircraft of claim 1 , further comprising a rudder coupled to the main body to control steering the aircraft.
7. The aircraft of claim 1 , said motor comprising a plurality of motors, each configured to drive said annular gear to drive said one or more blades, wherein each of said plurality of motors is located directly adjacent the annual gear.
8. The aircraft of claim 1 , wherein said one or more blades are fixed with respect to the annular gear.
9. The aircraft of claim 1 , wherein said one or more blades have a fixed permanent angle of attack for lift with respect to the main body.
10. The aircraft of claim 1 , further comprising a battery to provide power to said motor.
11. The aircraft of claim 1 , wherein the one or more blades is shorter in length and wider in chord than traditional helicopter blades.
12. A method of operating an aircraft, comprising:
providing a main body having a circular shape with a circular outer periphery;
providing one or more blades extending substantially horizontally outward from the main body at or about the circular outer periphery;
providing an annular gear located at or about the outer periphery and coupled to said one or more blades;
providing a motor directly adjacent the annual gear;
providing a planet gear directly coupled to the motor to drive said annular gear; and
driving the planet gear by the motor, to rotate the annular gear and rotate the one or more blades with respect to the main body.
13. The method of claim 12 , further comprising providing a rudder at the main body to control steering the aircraft.
14. The method of claim 12 , wherein said step of providing a motor comprises providing a plurality of motors, each configured to drive the annular gear, wherein each of the plurality of motors is located directly adjacent the annual gear.
15. The method of claim 12 , wherein said one or more blades are fixed with respect to the annular gear.
16. An aircraft comprising:
a main body having a circular shape with a circular outer periphery;
one or more blades extending substantially horizontally outward from said main body at or about the circular outer periphery, said one or more blades rotating with respect to said main body, wherein the one or more blades is shorter in length and wider in chord than traditional helicopter blades;
an annular gear coupled to said one or more blades;
a motor configured to drive said annular gear to drive said one or more blades; and
a planet gear directly coupled to the motor to drive said annular gear.
17. The aircraft of claim 16 , wherein the one or more blades are at least 50% shorter in length and 150% wider in chord than traditional helicopter blades.
18. The aircraft of claim 16 , wherein the aircraft is a helicopter-type aircraft.
