ROTOR BLADE COUPLING DEVICE OF A ROTOR HEAD FOR A ROTARY-WING AIRCRAFT
First Claim
1. A rotor blade coupling device for coupling with a rotor mast so as to create a rotor head of a rotary-wing aircraft, in particular a gyroplane or a helicopter, encompassinga rotor head central piece,at least two rotor blade holders fastened to the rotor head central piece for accommodating at least two rotor blades lying in a rotor plane, as well asat least one joining means between adjacent rotor blade holders,whereinthe rotor blade coupling device as the joining means encompasses at least one closed ring, wherein the at least one ring is arranged so as to cross all rotor blade holders at least at one joining section, and at least indirectly join together all rotor blade holders.

Abstract
In a rotor blade coupling device for coupling with a rotor mast so as to create a rotor head of a rotary-wing aircraft, in particular a gyroplane or a helicopter, encompassing a rotor head central piece, at least two rotor blade holders fastened to the rotor head central piece for accommodating at least two rotor blades lying in a rotor plane, as well as at least one joining means between adjacent rotor blade holders, a simplified structural design is to be achieved for the rotor blade coupling device, and the rotor blade coupling device is to enable an agile control. This is achieved by virtue that the rotor blade coupling device as the joining means encompasses at least one closed ring. The ring is arranged so as to cross all rotor blade holders at least at one respective joining location, and at least indirectly join together all rotor blade holders.
