The Gourdou-Leseurre GL-820 HY family of four-seat single-engined floatplanes were designed and built in France during the latter half of the 1930s by Gourdou-Leseurre. The GL-820 HY and GL-821 HY 02 were shipborne reconnaissance / observation aircraft, while the sole GL-821 HY was built as a torpedo carrier.

Design and development

The Gl-820 and GL-821 were low-wing monoplane floatplanes with four tandem open cockpits, (the Cockpits on the GL-821 HY 02 were enclosed). The wings, tailplanes and floats were all supported by a system of streamlined struts.

Conventional for its day, it was a single-bay biplane with un-staggered wings, its single engine mounted tractor-fashion underneath the upper wing and supported on struts in the interplane gap. Early examples had the pilot's open cockpit located aft of the wing, but this was later relocated forward of the wing.

Farman NC.470
