Abstract
A planar flexbeam unit (1, 40) as interface between a rotor shaft (2) and a multi-blade rotor, especially for a multi-blade main rotor of a helicopter. The planar flexbeam unit (1, 40) comprises a plurality of essentially planar torque arms (3-7, 41-46), each torque arm (3-7, 41-46) having essentially a concave profile (8) along its radial extension and being integral with its adjacent torque arms (3-7, 41-46). Each of said torque arms (3-7, 41-46) comprises two bundles (10-14) of straight, essentially uni-directional fibers agglomerated by a hardened synthetic resin and arranged along the essentially concave profile (8) along its radial extension. Each of said bundles passing into two essentially opposed torque arms (3-7, 41-46) without remarkable change of direction.
