Abstract

A compact and lightweight portable flyer.

Compared to the prior art, it is like an oversimplified synchropter without any casing or frame, without special control equipment, without servomechanisms. The body of the pilot is the sensors and the servomechanisms: just like a rider controls his bike with his body movements.

Claims

1. A flying machine comprising at least:

an opposed piston engine, said opposed piston engine having a first crankshaft and a second crankshaft, said first crankshaft and said second crankshaft being counter-rotating in synchronization;

a first rotor;

a second rotor;

a pilot;

characterized in that;

the first rotor is attached, by means of a constant velocity connection, at one end of the first crankshaft in order to rotate about an axis inclined to the axis of rotation of the first crankshaft,

the second rotor is attached, by means of a constant velocity connection, at one end of the second crankshaft in order to rotate about an axis inclined to the axis of rotation of the second crankshaft,

the first rotor and the second rotor being intermeshed,

the pilot is below the opposed piston engine, the control of the flight is made by changing the position and pose of the body of the pilot relative to the flying machine and by controlling the opposed piston engine revs.

2. As in claim 1 wherein in place of the pilot is a load and the control of the flying machine is made by sensors and servomechanisms.

3. As in claim 1 wherein the rotors are attached not to the crankshafts directly, but to secondary shafts driven by the crankshafts.

4. A flying machine comprising at least:

an opposed piston engine, said opposed piston engine having a first crankshaft and a second crankshaft, said first crankshaft and said second crankshaft being counter-rotating in synchronization having substantially parallel axes of rotation;

a first rotor, said first rotor being attached at one end of said first crankshaft;

a second rotor, said second rotor being attached at one end of said second crankshaft;

a pilot;

characterized in that;

the first rotor and the second rotor having blades sweeping substantially not plane surface around their rotor axis in order to rotate without collision,

the pilot is hanged below said opposed piston engine,

the control of the flight is made by changing the position and pose of the body of the pilot relative to said flying machine and by controlling the opposed piston engine revs.

5. A flying machine comprising at least:

a prime mover;

two rotors;

characterized in that;

the prime mover drives the two rotors to counter-rotate in synchronization,

the prime mover being of an arrangement that substantially reduces the reaction torque from the prime mover to the flying machine as the prime mover provides torque to the two rotors,

the pilot or load is supported on the prime mover,

the control of the flight is made by changing the position and pose of the body of the pilot, or of the load, relative to the flying machine and by controlling the prime mover revs.

10. As in claim 5 wherein the prime mover is a wide Vee almost opposed piston engine having two inclined counter-rotating crankshafts sharing the same combustion chamber to allow the use of intermeshing long blade conventional rotors directly driven by the inclined crankshafts.

11. As in claim 5 wherein the prime mover is a wide Vee almost opposed piston engine having two inclined counter-rotating crankshafts sharing the same combustion chamber, the two rotors are intermeshing having blades sweeping substantially not plane surfaces around their rotation axis.

12. As in claim 5 wherein neither the power shafts of the prime mover are necessarily parallel, nor the blades of the rotors are necessarily perpendicular to their rotation axis, nor the rotors are necessarily fixed on their shafts but can be connected by means of Cardan connection, nor the rotors are necessarily of constant pitch.

6. As in 5 wherein the two rotors are intermeshing, having inclined rotation axes, the rotors being driven by means of constant velocity connections.

7. As in 5 wherein the two rotors are intermeshing, having blades sweeping substantially not plane surfaces around their rotation axis, in order to rotate without collision.

8. As in 5 wherein one of the two rotors is over the prime mover while the other rotor, of the two rotors, is below the prime mover.

9. As in 5 wherein the prime mover comprises two reciprocating engines and a mechanism to keep their crankshafts counter-rotating in synchronization and in proper phase.
