The Potez X was a French 1920s general-purpose colonial transport aircraft designed and built by Potez.

Development

The Potez X was a three-engined biplane with a fixed nosewheel landing gear supplemented with a tailskid.[1] The first variant was the Potez X A which was powered by three 140 hp (104 kW) Hispano-Suiza 8Aa piston engines, two strut-mounted between the upper and lower wings and one nose-mounted.[1] It had an enclosed cabin for 10 passengers with the pilot in an open cockpit behind the cabin.[1] Later the engines were changed to more powerful Hispano-Suiza 8Ab versions.[1] Two other variants were built with 280 hp (209 kW) Hispano-Suiza 8Bec engines, the X B was a military variant and the X C a commercial variant.[1]

The Potez X formed the basis of two similar airliners in the Potez XVIII and Potez XXII.[2][3]
