Gourdou-Leseurre GL-22

10/31/2011. Evolved in parallel with the GL-21, the GL-22 (Type B3) also made its debut in 1920. It differed from the GL-21 primarily in having a new wing profile, steel-tube in place of light alloy wing bracing struts, a modified frontal radiator and a revised cockpit interior. The 180 hp Hispano-Suiza 8Ab eight-cylinder water-cooled in-line V-engine and twin 0.303 in (7.7 mm) Vickers machineguns were retained, but some structural revision reduced empty weight by 154 lb (70 kg). The prototype, like that of the GL-21, was initially flown with twin undercarriage struts on each side, but a triple-strut arrangement was adopted for the series model.

With gun armament the aircraft was designated GL-22 C1 (C = Chasse), but without armament it was designated GL-22 ET1 (ET = Entrainement de Transition) and was intended for the advanced training role. The first order for the GL-22 was placed with Gourdou-Leseurre on December 13, 1920, twenty examples of the single-seat fighter subsequently being built for export to Estonia, Latvia and Czechoslovakia, and thirty of the training version being supplied to France's Aviation Marine. In addition, a manufacturing licence was acquired by the newly-established Zmaj concern in Yugoslavia.
