The Leduc 0.22 was the prototype Mach 2 fighter jet built in France in 1956.
draft
The Leduc 0.22 was the first attempt at a practical application of the ramjet technology that had been developed with the test aircraft Leduc 0.10 and Leduc 0.21. In contrast to the previous aircraft designs, the Leduc 0.22 had swept-back wings and a coaxial turbojet ramjet engine. This made it possible to start without outside help.
history
The first flight took place on December 26, 1956. The machine was still powered by a conventional jet engine. The ramjet engine was ignited for the first time on May 18, 1957 during the 34th flight. Another 80 flights took place before the project was abandoned in favor of the more conventional Dassault Mirage III . A second prototype was already under construction.
The Leduc 0.22, designed as a supersonic fighter jet, turned out to be incapable of exceeding the speed of sound of Mach 1 due to the air resistance generated and its fuselage, which was not constructed according to the area rule . The cancellation of the project marked the end of René Leduc's aircraft development.
The Leduc 0.22 is exhibited in the Musée de l'air et de l'espace in Le Bourget .
