German aircraft builders from the company "Siebel" organized the start of work on the design of the multipurpose aircraft Siebel Si 204 in 1938. Despite the fact that before the aircraft designers did not create such aircraft, in less than two years, they not only successfully implemented the project, but in fact, the aircraft was even able to rise into the air. It should be clarified that the first test flight was very disappointing for Siebel aircraft builders, since the aircraft did not possess the required stability and moved very slowly, and as a result, already in 1941, the Siebel Si 204 aircraft underwent a number of significant changes, and another The prototype was much more successful, in connection with which, the aircraft was sent to mass production.

Despite the fact that the production of aircraft Siebel Si 204 model began only in 1942 year, in just three years of release, the German aircraft manufacturers have created more than 1200 copies of aircraft, some of which could not only be used intensively in the field of civil aviation, but and become a full-fledged military aircraft, suitable for the transport of troops and heavy loads.

The crew of the aircraft Siebel Si 204 consists of only two people, while in the aircraft cabin can accommodate up to 8 passengers, making the aircraft highly suitable for flight on the routes of local and regional importance. In addition to the transport of persons, aircraft Siebel Si 204 can also be transported on its board and to 1650 kg of payload, which made him very popular in the civil and military spheres.

The power plant air Siebel Si 204 ship model consists of two piston engines brands Argus As 411-A1, each of which is capable of traction in 592 hp, provided the aircraft and high lifting power. The maximum flight speed of the aircraft was 365 km \ h., While following distance is limited 1300 kilometers, taking into account the period of production of the aircraft is considered to be quite acceptable and promising.

In mass production, in addition to create a prototype 14, Siebel Si 204 model aircraft is in the following versions and variants:

  • Siebel Si 204 - The basic pre-production and production version of the airplane;
  • Siebel Si 204D - An improved version of the aircraft, with some technical improvements to the design;
