The CAMS 37 was a flying boat and amphibious aircraft manufactured by Chantiers Aéro-Maritimes de la Seine in France in the mid-1920s . The biplane was originally developed as a military maritime reconnaissance aircraft , but was then also manufactured in different versions for civil aviation.
history
It was the first design by Maurice Hurel , who was the new chief designer at CAMS. The prototype made its first flight in early 1926 and was presented at the Paris Air Show that same year . The first production version with an open cockpit was the amphibious version CAMS 37A, which was bought by the French Navy and the Portuguese government. 185 of the 37A alone were delivered.
The CAMS 37 was a conventional double-decker flying boat and its design was very similar to the previous CAMS designs. The CAMS 37 were powered by a W engine , a reciprocating piston engine with three rows of cylinders from the Lorraine 12Ed series with an output of 331 kW (450 hp) and a pusher propeller. The motor nacelle was mounted on struts between the lower and upper wing. The 37 was manufactured in both wood and all-metal versions.
A total of around 340 of the 37 series were manufactured at CAMS.
Outside Europe, the type CAMS 37/11 trainer was in use, in Tahiti until January 15, 1941 and in Indochina until 1942. 110 units of the 37/11 series were produced. The CAMS 37 was also one of the oldest flying boats to be used during World War II .
