Stop-Rotor Rotary Wing Aircraft

Some unmanned aircraft designs attempt to combine the vertical takeoff and landing (VTOL) and hover capabilities of a helicopter with the increased speed and range capabilities of fixed-wing airplanes. Stop-rotor “nose-sitter” configurations — so named because the aircraft takes off and lands from a...
