UAVOS Bearing-less Rotor System

UAVOS announced that it had completed flight tests of its advanced bearingless rotor system installed on the UVH 25EL unmanned helicopter. Torsion bar is aimed to provide an effective damping action against the dynamic components of the forces and torques acting on the rotor. The new rotor design has resulted in increasing Time Between Overhauls (TBO) and therefore in low life-cycle costs, better hub design, and superior handling qualities. Torsion Bar for a main helicopter rotor is designed to be mounted on a helicopter with maximum takeoff weight of 50 kg.
