Patent number: 6196800Abstract: A rotor blade arrangement for a bearingless rotor of a helicopter includes a flexbeam connecting an airfoil blade to a rotor head, and a control sleeve surrounding the flexbeam. The control sleeve is relatively stiff, but the flexbeam has portions that are flexible so as form a fictitious flapping hinge, lead-lag hinge, and torsion axis, which respectively enable flapping, lead-lag pivoting, and torsional movements of the airfoil blade. The inboard end of the control sleeve is secured to the root end of the flexbeam near the rotor head to prevent lateral displacements therebetween. Damping elements are arranged within the enclosure of the control sleeve at a location between the fictitious lead-lag hinge of the flexbeam and the transition region at which the flexbeam transitions into the airfoil blade.Type: GrantFiled: May 27, 1999Date of Patent: March 6, 2001Assignee: Eurocopter Deutschland GmbHInventors: Karl Bauer, Gerald Kuntze-Fechner, Gerhard Hausmann, Bernhard Enenkl

Patent number: 6168379Abstract: A helicopter rotor blade includes a main airfoil body (12) and a movable control flap (3) incorporated in the trailing edge profile of the airfoil body. The flap (3) is movably connected to the main airfoil body (12) by a flexibly bendable junction element (4), and is actuated by a piezoelectric actuator unit (5) via a push/pull rod (6) and a lever arm (7), whereby the control flap is deflected relative to the main airfoil body. The junction element (4) is preferably a continuous integral fiber-reinforced composite component having a flexible bending portion (42) with a reduced thickness in comparison to the adjoining portions, whereby the reinforcing fibers extend continuously through the joint in the direction of the connection between the main airfoil body and the flap.Type: GrantFiled: March 1, 1999Date of Patent: January 2, 2001Assignee: Eurocopter Deutschland GmbHInventor: Karl Bauer

Patent number: 6126398Abstract: A rotor blade for a bearingless rotor of a helicopter includes a lift-generating airfoil blade, a flexbeam connecting the airfoil blade to a rotor head, and a control sleeve enclosing the flexbeam. The junction between the flexbeam and the airfoil blade is a separable junction (J) to allow the airfoil blade to be folded in a simple manner while maintaining a high lead-lag stiffness and reduced structural height of the junction (J). The junction (J) is formed by two connection arms (5.1, 5.2) arranged side-by-side in the lead-lag plane (E.sub.R) of the rotor blade (R). Preferably, the two connection arms extend from the inboard end of the airfoil blade (3) and receive the head (1.1) of the flexbeam (1) therebetween lying in the lead-lag plane (E.sub.R). A connecting fixture (6) connects the connection arms (5.1, 5.2) to the flexbeam head (1.1) using fasteners such as bolts (V.sub.1, V.sub.2) that are spaced laterally from each other at a spacing distance of at least 1.Type: GrantFiled: May 27, 1999Date of Patent: October 3, 2000Assignee: Eurocopter Deutschland GmbHInventors: Karl Bauer, Gerald Kuntze-Fechner
