The autogyro was resurrected after World War II when Dr. Igor Bensen, a Russian immigrant in the United States, saw a captured German U-boat's Fa 330 gyroglider and was fascinated by its characteristics. At work, he was tasked with the analysis of the British military Rotachute gyro glider designed by an expatriate Austrian, Raoul Hafner.
The Fairey Rotodyne was a 1950s British compound gyroplane designed and built by Fairey Aviation and intended for commercial and military uses. [1] A development of the earlier Fairey Jet Gyrodyne, which had established a world helicopter speed record, the Rotodyne featured a tip-jet-powered rotor that burned a mixture of fuel and compressed air bled from two wing-mounted Napier Eland turboprops.
The ArrowCopter was designed to comply with British BCAR Section T rules. It features a single main rotor, a two-seats in tandem configuration enclosed cockpit with a bubble canopy, stub wings, tricycle landing gear and a four-cylinder, liquid and air-cooled, four-stroke, dual-ignition turbocharged 115 hp (86 kW) Rotax 914 engine in pusher configuration.
Although the official record for fastest piston-engined aeroplane in level flight was held by a Grumman F8F Bearcat, the Rare Bear, with a speed of 850.23 km/h (528.31 mph), the unofficial record for fastest piston-engined aeroplane in level flight is held by a British Hawker Sea Fury at 880 km/h (547 mph).
Juan de la Cierva was born to a wealthy, aristocratic Spanish family, and for a time his father was the war minister. [4] At the age of eight he was spending his pocket money with his friends on experiments with gliders in one of his father's work sheds.
The CarterCopter is an experimental compound autogyro developed by Carter Aviation Technologies in the United States to demonstrate slowed rotor technology. On 17 June 2005, the CarterCopter became the first rotorcraft to achieve mu-1 (μ=1), an equal ratio of airspeed to rotor tip speed, [3] but crashed on the next flight [1] and has been inoperable since.

Before the H-1 took to the air, the world absolute speed record was 440.7 mph (709.2 km/h), held by a Macchi M.C.72 seaplane and set in October 1934. The landplane record was 314.32 mph (505.85 km/h), averaged by Raymond Delmotte in a Caudron C.460 .
