Potez 840 - French multipurpose passenger aircraft designed and manufactured by «Potez» company for the period from 1961 1967 year.

The multipurpose aircraft began to be designed by the French aircraft engineers in the middle of the 50-ies of the last century, while the designers succeeded in creating an aerodynamically beautiful design of the aircraft, equip it with powerful engines and enable the transport of up to 18 people on board. Nevertheless, in view of the fact that the aircraft was being developed for quite a long time, the aircraft turned out to be very expensive, and in addition to everything it was very costly in terms of its operational properties, and therefore did not get mass distribution - for the entire production period it was built Only 8 aircraft of this model, of which, according to the data for 2015 year, it was known about the existence of only two aircraft.

Thanks to the joint work of French engineers and a group of international designers, it was possible to build a completely modern aircraft even by the current time standards, which is suitable for bridging long distances up to 3 thousands of kilometers at sufficiently high speeds, however, due to the Potez 840 aircraft having powerful turboprop engines , the plane had enormous fuel consumption, which made the operation of these aircraft very expensive.

Salon can accommodate aircraft on board to passengers 18, in turn, taking into account the time of the appearance of the aircraft is quite acceptable, however, for a number of very constructive reasons, the aircraft was not suitable for the transportation of goods, and positioned solely as a passenger aircraft.

In addition to civil aviation, the Potez 840 model was also supposed to be used in the military sphere, and it was expected that the aircraft could carry both military troops and be used as an observation aircraft or reconnaissance aircraft, however, for the reasons mentioned above, the aircraft in the air force and not enrolled.

The power plant of the aircraft Potez 840 includes four turboprop aircraft engines Turbomeca Astazou X (depending on version), which can develop thrust order 640 hp each. Thanks to the powerful propulsion system, the aircraft could accelerate to speeds in 520 km / h. However, an extremely high fuel consumption was a great disadvantage, which is why the project was considered rather a failure.

During his rather short period of production of the Potez aircraft models produced in 840 3 basic versions:

  • Potez 840 - Manufacturing base version equipped engines Brand Astazou;
  • Potez 841 - A modified version equipped with Pratt & Whitney Canada PT6A-6 engines (hp 550);
  • Potez 842 - An improved version with engines Turbomeca Astazou X.
