The PA-890 Slowed Rotor Compound Helicopter electric vertical takeoff and landing aircraft (eVTOL) project features a large four-bladed main rotor, a variable incidence wing that rotates up to 90 degrees to minimize download for efficient hovering, and swiveling tail rotor that provides anti-toque and yaw control. As the PA-890 transitions to forward flight the wing rotates to a horizontal position providing lift to offload the rotor and the tail rotor swivels to provide efficient forward propulsion. With lift and thrust demands on the rotor relieved, the rotor RPM is slowed. The combined effect is a dramatic increase in efficiency and range while decreasing noise.
