Product overview
The United Aircraft TD220 rotor system is designed for the TD220, a 350 kg class general-purpose small coaxial unmanned helicopter. It combines a semi-articulated hub with single-pin blades and uses United Aircraft's electrically controlled coaxial rotor technology. An elastomeric damper at the blade root accommodates lead-lag motion, while a metal bearing inside the hub enables feathering, or blade pitch changes. The 350 kg designation describes the helicopter's weight class, rather than the rotor system's mass or the aircraft's payload.
