In 1925, the Caudron firm released the C.183 transport aircraft. It was a modification of the C.81, sharing the same wingspan but being 1.1 meters longer and 60 kg heavier. This development aimed to improve upon its predecessor’s capabilities.
Origin and Development of the Caudron C.183
Its powerplant also differed significantly from the C.81. Instead of the nose-mounted Lorraine-Dietrich 12Db engine, a more powerful Salmson CM19 (550 hp) was used. Despite this increased engine power, its passenger capacity and flight characteristics remained at approximately the same level as the C.81.
Limited Production and Legacy
Consequently, only a single unit of the C.183 was ever produced. Its registration number, F-ESAI, was inherited directly from the C.81, highlighting its limited production run and close lineage to the earlier model.
