In a rotary wing aircraft a bar () of composite matrix material has a longitudinal axis () perpendicular to a cross section with upper and lower surfaces (). At least one torsion box () comprises an upper and a lower layers () respectively offset of a longitudinal axis () and of the upper and the lower surfaces (), said upper and lower layers () being laterally joint, while cross sections are filled with the first group of fibers extending essentially parallel to the longitudinal axis ().

Bar of composite matrix material

A connection means () for mounting a rotor blade () to a rotor hub, particularly for mounting a rotor blade () to a rotor hub of a helicopter, with at least two bolts () inserted vertically relative to a main plane of said rotor blade () into an end () of said rotor blade () that is generally directed towards the rotor hub. At least two bolts () are arranged distant from each other along a longitudinal axis () of said rotor blade () to said rotor hub.
