Rotor assembly

摘要

A rotor assembly for helicopter vehicles for stabilizing the aircraft and thus providing an easy way of controlling pitch and roll of the aircraft by respectively associated magnetic actuators. The rotor assembly comprises a rotor with two flexible rotor blades, a rotor head rotationally coupled to the rotor shaft, a rotating swash plate, with at least three fly bars extending therefrom. The swash plate is rotationally coupled to the rotor shaft and adjusted to tilt in all directions relative to a plane perpendicular to the rotor shaft. The rotor head is hinged to the rotor shaft in one direction so that the rotor head and the rotor blades jointly are not able to tilt around their transversal axis. The coupling between the rotating swash plate and the rotor head provide synchronized tilt movements between the rotor head and the rotating swash plate around the longitudinal axis of the rotor head.

1. A rotor assembly comprising:
a rotor shaft and at least two flexible rotor blades coupled to a rotor head that is rotationally coupled to the rotor shaft, each rotor blade extending outwards from the rotor shaft such that the rotor head and the at least two rotor blades together define a longitudinal axis; a rotating swash plate defining a centre through which the rotor shaft runs, the rotating swash plate having at least three flybars extending from the rotating swash plate and being symmetrically distributed around the centre of the rotating swash plate, each of the at least three flybars having an outer tip provided with a weight element, the swash plate being rotationally coupled to and synchronized with the rotor shaft and adjusted to tilt in all directions relative to a plane perpendicular to the rotor shaft; a non-rotating swash plate defining a centre through which the rotor shaft runs, the non-rotating swash plate being adjustable to tilt in all directions relative to a perpendicular plane of the rotor shaft with tilting movements synchronized with the rotating swash plate; and a plurality of wheels disposed about the rotating swash plate, the plurality of wheels contacting a surface of the non-rotating swash plate, wherein the rotor head is hinged to the rotor shaft in one direction so that the rotor head and the rotor blades jointly are able to tilt around their concurrent longitudinal axis, but not around their traversal axis, and the rotating swash plate is directly coupled to the rotor head by two tilt links being hinged to both the rotating swash plate and the rotor head, one at each side of the longitudinal axis of the rotor head, providing synchronized tilt movements between the rotor head and the rotating swash plate around the longitudinal axis of the rotor head.
