The Airbus RACER (Rapid and Cost-Effective Rotorcraft) is an experimental high-speed compound helicopter developed by Airbus Helicopters from the Eurocopter X³. It was revealed at the June 2017 Paris air show, final assembly slated to start in mid-2020 for a 2021 first flight. Actual first flight was in 2024.

The Eurocopter X³ (X-Cubed) is a retired experimental high-speed compound helicopter developed by Airbus Helicopters (formerly Eurocopter).A technology demonstration platform for "high-speed, long-range hybrid helicopter" or H³ concept, [1] the X³ achieved 255 knots (472 km/h; 293 mph) in level flight on 7 June 2013, setting an unofficial helicopter speed record.
The Sikorsky S-72 was an experimental Sikorsky Aircraft compound helicopter developed as the Rotor Systems Research Aircraft (RSRA) for the National Aeronautics and Space Administration (NASA) and the United States Army. The RSRA was a testbed for rotor and propulsion systems for high-speed. [1]
The Lockheed XH-51 (Model 186) is an American single-engine experimental helicopter designed by Lockheed Aircraft, utilizing a rigid rotor and retractable skid landing gear. The XH-51 was selected as the test vehicle for a joint research program conducted by the United States Army and United States Navy to explore rigid rotor technology.
The Model 1-G flew until a crash in Chesapeake Bay on 20 July 1955, destroying the prototype aircraft but not seriously injuring the pilot. The Transcendental 1-G was the first tiltrotor aircraft to have flown, and it accomplished most of a helicopter-to-aircraft transition in flight to within ten degrees of true horizontal aircraft flight.
