Abstract

A rotor assembly includes a first rotor, a second rotor and a damper system. The first and second rotors are arranged to be rotated about a common axis for thrust generation by a drive system. The first rotor is rotatable about the common axis relative to the second rotor between a stowed configuration of the rotor assembly in which a rotor blade of the first rotor and a rotor blade of the second rotor are substantially angularly aligned and a deployed configuration in which the rotor blade of the first rotor and the rotor blade of the second rotor are angularly misaligned. The damper system is arranged to generate a damper force opposing the relative rotation between the first and second rotors in at least one of the direction towards the stowed configuration and the direction towards the deployed configuration.
