The Blériot-SPAD S.33 was a rated for four to five passengers biplane - passenger aircraft of the French manufacturer Blériot Aéronautique from the 1920s.

history

The S.33 took off for the first time on December 12, 1920. Since some of the then still young airlines showed interest in the S.33, a further 41 copies were built after the two pre-series machines.

The French company Compagnie Franco-Romaine received 20 machines and used them between France and Eastern Europe. In 1925 this company became the CIDNA (Compagnie Internationale De Navigation Aérienne), which in 1933 merged with other companies to form Air France . The S.33 were used at times as far as Istanbul .

During the 1930s, the S.33 and its variants were the standard passenger aircraft of some small European airlines.

construction

The Blériot-SPAD S.33 was a single-handled double-decker. The lower wings were made shorter than the upper, the upper wings were heavily swept, the lower, however, were at right angles to the fuselage. The ailerons were on the lower wings. The machine had a two-wheeled chassis and a tail spur.

The S.33 was designed for four passengers who had wicker chairs in the closed cabin in the fuselage. The passengers had a view of the outside through three portholes on each side of the fuselage. A fifth passenger could take a seat next to the pilot in the open cockpit . The cockpit was roughly in the middle of the fuselage behind the passenger cabin.

The prototype was still equipped with a Salmson radial engine with an output of 184  kW (250  PS ). The series models received the 7 kW more powerful Salmson C.9 radial engine.
