The Blériot Bl-115 was a French biplane airliner of the 1920s, best remembered for the part it played in the French exploration of Africa. For its day, it was a large aircraft, mounting one pair of engines on the upper wing and one pair on the lower. First flying on 9 May 1923, the prototype crashed on 23 June, killing its pilot, Jean Casale.
The Breda A.4 was a biplane trainer produced in Italy in the mid-1920s. It was of conventional configuration with a two-bay unstaggered wing cellule and seating for the pilot and instructor in tandem open cockpits. Apart from civil use, the A.4 was also adopted by the Regia Aeronautica as a trainer. At least some examples were produced in floatplane configuration as the A.4idro.
The CAMS 30E was a two-seat flying boat trainer built in France in the early 1920s. It was the first aircraft designed for CAMS by Raffaele Conflenti after he had been recruited by the company from his previous job at Società Idrovolanti Alta Italia (SIAI). It was a conventional design for the era featuring a two-bay equal-span unstaggered biplane wing cellule. The prototype was exhibited at the 1922 Salon de l'Aéronautique and evaluated the following year by the Aéronautique Maritime. The type's favourable performance led to an order of 22 machines for the French military and an export order of seven for Yugoslavia and four for Poland.
The CAMS 55 was a reconnaissance flying boat built in France in the late 1920s which equipped the French Navy throughout the 1930s.
The Farman F.120 were a family of multi-engine monoplane aircraft designed and produced by the French aircraft manufacturer Farman Aviation Works. It was operated in a diverse range of purposes, including as a commercial airliner and as a military bomber aircraft.
The Morane-Saulnier MS.230 aircraft was the main elementary trainer for the French Armée de l'Air throughout the 1930s. Almost all French pilots flying for the Armée de l'Air at the outbreak of World War II had had their earliest flight training in this machine. It was the equivalent of the Stearman trainer in the United States air services and the de Havilland Tiger Moth in the British Royal Air Force.
The FBA 21 and 23 were small flying boat airliners built in France in the mid-1920s. Their development was an attempt by FBA to develop a commercial version of their FBA 19 bomber which had failed to attract orders from military buyers. Retaining the same basic design as their predecessor, the Model 21 added an enclosed cabin for four passengers. Unfortunately for FBA, they aroused as little interest as their military counterparts, and only a handful were built in a number of slight variations, including one example of a dedicated mail plane.
The Renard Epervier was a Belgian prototype single-seat all-metal fighter monoplane designed by Alfred Renard at the Societé Anonyme Avions et Moteurs Renard for a government-sponsored design contest in 1928. The Epervier Type 2 was built and flown in 1928, by Belgian aircraft manufacturer Stampe et Vertongen. It carried an armament of two synchronised 7.7mm guns and was lost in September 1928 after failing to recover from a flat spin. A second prototype, the Epervier Type 2bis, introduced revised streamlined fairings for the cantilever mainwheel legs, mainwheel spats and cylinder aft-fairings and was built by SABCA.
The Lioré et Olivier LéO H-13 was a French biplane two-engine flying boat of the 1920s, built in passenger and military variants.
The Letord Let.5 was probably the most numerous of a family of 3-seat reconnaissance bombers, designed and built in France from 1916, originally to an A3 specification from the STAé.
The Nieuport-Delage NiD 38 was a touring aircraft built in small numbers in France in the early 1920s. It was a single-bay biplane of conventional design with an enclosed cabin for two passengers and an open cockpit for the pilot.
The Potez X was a French 1920s general-purpose colonial transport aircraft designed and built by Potez.
The Hanriot H.35 was a 1920s French intermediate training monoplane designed and built by Avions Hanriot.
The Stampe et Vertongen RSV.22 was a training biplane produced in Belgium in the 1920s.
The CAMS 36 was a 1920s French flying boat designed and built by Chantiers Aéro-Maritimes de la Seine. It was originally conceived as a single-seat fighter but evolved as a racer to compete in the 1922 Schneider Trophy race. Lack of funds in 1922 and an accident in 1923 meant the two aircraft built failed to participate in a Schneider race.
The Hanriot H.34 was a basic trainer designed in France in 1924 which did not reach production. It was a parasol wing aircraft, seating two in tandem.
The CAMS 54 was a strengthened and more powerful version of the French CAMS 51 civil transport and naval reconnaissance flying boat, developed for transatlantic flights. It is sometimes referred to as the 54 GR.
The SPAD S.42 was a French biplane trainer aircraft of the early 1920s, developed by Société Pour L'Aviation et ses Dérivés (SPAD) from prolific SPAD S.XIII fighter.
The Blériot-SPAD S.92 was a French one-seat, single-engine biplane flight training aircraft designed in the 1920s
The Blériot-SPAD S.62 was a French one-seat, single-engine biplane flight training aircraft designed in the 1920s. It was presented at the Military Airplane School Contest of 1923.
