The helicopter body is suspended from an instrumented joint that is mounted at the end of an arm and is free to pitch about its centre. The other end of the arm is fastened to the base using a two degree of freedom joint, allowing the helicopter to rotate about the vertical axis as well as up and down. The other end of the arm has an adjustable counterweight that changes the effective mass of the helicopter system – making it light enough to be lifted by the thrust from the propellers. All axes are measured using high-resolution encoders to obtain precise position feedback. The slip ring mechanism on the vertical axis allows the body to rotate continuously by eliminating the need for any wires to connect the motors and encoders to the base. The front and back propellers control the movement of the helicopter.

  • Three degrees of freedom (3 DOF): body rotates about pitch, travel and elevation axes
  • Propellers driven by high-quality Pittman DC motors
  • High-resolution optical encoders for precise position measurements
  • Slip ring allows infinite motion about the vertical and travel axis
  • Easy-connect cables and connectors
  • Precise, stiff and heavy-duty machined components
