The Advancing Blade Concept system consisted of two rigid, contra-rotating rotors (30 inches apart)[1] which made use of the aerodynamic lift of the advancing blades. At high speeds, the retreating blades were offloaded, as most of the load was supported by the advancing blades of both rotors and the penalty due to stall of the retreating blade was thus eliminated.[2][3] This system did not require a wing to be fitted for high speeds and to improve maneuverability,[4] and also eliminated the need for an anti-torque rotor at the tail.[5] Forward thrust was provided by two turbojets, which allowed the main rotor to only be required to provide lift. It was found to have good hover stability against crosswind and tailwind. With jets installed, it lacked power to hover out of ground effect and used short take-off and landing for safety reasons.[4]
