Role | Airliner |
National origin | France |
Manufacturer | Potez |
First flight | 1920 |
Number built | 30 |
Developed from | SEA IV |
The Potez IX was an early airliner produced in France in the 1920s, a further development of the SEA IV that Henry Potez had co-designed during the First World War. [1] [2]
The design mated an entirely new fuselage to the wing and tail structures of the earlier military aircraft. [1] [2] [3] This fuselage was very deep, nearly filling the interplane gap, and carried within it a fully enclosed cabin with seating for four passengers. [1] [2] [3] The nose area was carefully streamlined [2] with curved aluminium, [4] but other aspects of the construction were conventional for the day; wooden structures skinned in plywood (the passenger cabin) or fabric (the rest of the aircraft). [5] The pilot sat in an open cockpit aft of the cabin. [2] [5]
The prototype flew in 1920, [6] and was followed by around thirty production examples that differed from it in having a larger tail fin and rudder. [2] The Compagnie générale transaérienne operated Potez IXs on cross-channel air services between Paris and London. [6] The Compagnie Franco-Roumaine de Navigation Aérienne flew these [5] on routes linking Paris to Warsaw via Strasbourg and Prague, and from Paris to Budapest via Strasbourg and Vienna, later extending its services to Bucharest and Constantinople. [6] Franco-Roumaine, and its successor airline CIDNA operated the Potez IX until 1928. [1] [7]
The Potez IX S, a one-off modified version with wings of larger area, [2] flew in the Grand Prix de l'Aéro Club de France in June 1921 with Gustave Douchy at the controls. [8] Douchy was disqualified in the third stage of the competition. [8]
