Aircraft of the Month for October 2001

Leduc 0.22

by Alex Stoll


he 0.22 was the last of René Leduc's experimental ramjet fighters. After designing the successful 0.21 aircraft, the 0.22 was developed from it. Modifications included a 36.47 kN (8,180 lb) thrust SNECMA Atar D.3 turbojet mounted within the ramjet, to allow the aircraft to take off and accelerate on its own power to speeds where the ramjet could operate (about Mach 0.4/340 kph/185 kts). Although the 0.22 made its first flight on 25 December 1956 and completed over 30 flights, it was never flown under ramjet power due to government financial support being cut. The withdrawal of this funding also resulted in the cancellation of the project.
