Abstract
A flying toy comprises a first wing and a second wing attached to and extending from opposite sides of a fuselage. There is a first propulsion unit, having a first motor and a first propeller system rotated by the first motor, mounted with the first wing; and a second propulsion unit, having a second motor and a second propeller system rotated by the second motor, mounted with the second wing. Each propulsion system has main blades and auxiliary blades which interact with each other. Each of two wings can be angled relative to horizontal independently. The toy can operate as a plane or helicopter.
Claims22
A flying toy comprising:
- a fuselage having a first wing and a second wing attached to and extending from opposite sides of the fuselage;
- a first propulsion unit, having a first motor and a first propeller system rotated by the first motor, mounted with the first wing;
- a second propulsion unit, having a second motor and a second propeller system rotated by the second motor, mounted with the second wing;
- the first propeller system and the second propeller system respectively being driven by a respective rotor shaft of respective first and second motors with which a respective set of main blades are mounted;
- a first auxiliary rotor driven by the rotor shaft of the first rotor for rotation in the sense of rotation of the first rotor, the first auxiliary rotor being mounted such that the generally longitudinal axis of the first auxiliary rotor is located at an angle relative to a generally longitudinal axis one of the main blades of the first rotor, and wherein the generally longitudinal axis of the first auxiliary rotor is along a center line of the first auxiliary rotor passing to the rotor shaft, and wherein the auxiliary rotor is mounted in a swinging relationship on a first oscillatory shaft and the swinging motion about the first auxiliary shaft, such that the swinging motion of the first auxiliary rotor controls the angle of incidence of at least one of the main blades of the first propeller system;
- and
- a second auxiliary rotor driven by the rotor shaft of the second rotor for rotation in the sense of rotation of the second rotor, the second auxiliary rotor being mounted such that the generally longitudinal axis of the second auxiliary rotor is located at an angle relative to a generally longitudinal axis one of the main blades of the second rotor, and wherein the generally longitudinal axis of the second auxiliary rotor is along a center line of the second auxiliary rotor passing to the rotor shaft, and wherein the second auxiliary rotor is mounted in a swinging relationship on a second oscillatory shaft and the swinging motion about the second auxiliary shaft, such that the swinging motion of the second auxiliary rotor controls the angle of incidence of at least one of the main blades of the second propeller system.
