Abstract
A system which includes a first propeller, a second propeller, an electromagnetic field emitter that is coupled to the first propeller, and an electromagnetic field receptor that is coupled to the second propeller. The electromagnetic field emitter emits an electromagnetic field and in response to the electromagnetic field, the electromagnetic field receptor and the second propeller rotate in a first rotational direction and the electromagnetic field emitter and the first propeller rotate in a second and counter-rotational direction.
Claims14
A system, comprising:
- a first propeller;
- a second propeller;
- an electromagnetic field emitter that is coupled to the first propeller;
- an electromagnetic field receptor that is coupled to the second propeller, wherein the electromagnetic field emitter emits an electromagnetic field and in response to the electromagnetic field:
- the electromagnetic field receptor and the second propeller rotate in a first rotational direction;
- and
- the electromagnetic field emitter and the first propeller rotate in a second and counter-rotational direction;
- and
- at least one of the following:
- a first mechanical coupling that mechanically reorients a direction of rotation between the electromagnetic field receptor and the second propeller such that the first propeller and the second propeller are not co-axial;
- or
- a second mechanical coupling that mechanically reorients a direction of rotation between the electromagnetic field emitter and the first propeller such that the first propeller and the second propeller are not co-axial.
A method, comprising:
- providing a first propeller;
- providing a second propeller;
- providing an electromagnetic field emitter that is coupled to the first propeller;
- providing an electromagnetic field receptor that is coupled to the second propeller, wherein the electromagnetic field emitter emits an electromagnetic field and in response to the electromagnetic field:
- the electromagnetic field receptor and the second propeller rotate in a first rotational direction;
- and
- the electromagnetic field emitter and the first propeller rotate in a second and counter-rotational direction;
- and
- providing at least one of the following:
- a first mechanical coupling that mechanically reorients a direction of rotation between the electromagnetic field receptor and the second propeller such that the first propeller and the second propeller are not co-axial;
- or
- a second mechanical coupling that mechanically reorients a direction of rotation between the electromagnetic field emitter and the first propeller such that the first propeller and the second propeller are not co-axial.
