Harbin Y-11 - a multi-purpose twin-engine vysokoplan designed and manufactured by Chinese aircraft manufacturer «Harbin Aircraft Manufacturing Corporation».

Start of design work on the creation of a multi-purpose aircraft Harbin Y-11 1974 was laid in the year, and is already a little more than a year, the Chinese aircraft manufacturers presented the first prototype of the aircraft, which was successfully tested in December 1975 years.

Aircraft Harbin Y-11 has quite attractive design and is quite suitable for the implementation of passenger traffic (mostly on local air routes) and to transport different kinds of goods, the total weight does not exceed 1200 kilos.

During the two years of production, with 1975 1977 of the year, the Chinese aircraft engineer was built 50 first aircraft of this model, however, because of the actual lack of orders, which was associated with far imperfect flight performance of the aircraft, the production was closed.

Depending on the model, Harbin Y-11, on board the aircraft can accommodate up to 9 people - two pilots and seven passengers, which did not satisfy the requirements of the Chinese airlines, and in fact, made this operation costly aircraft. To the greatest extent aircraft Harbin Y-11 used to transport all sorts of goods, aided by a good enough response payload, and is an acceptable maximum distance flight component 995 kilometers.

Several units of the model aircraft Harbin Y-11 also found its application in military aviation, which were mainly used to patrol the area and implementation of observation flights.

Aircraft Harbin Y-11

The power plant of the Harbin Y-11 aircraft is represented by two piston aircraft engines of the Huosai-6A model, each of which was capable of developing tractive effort in 285 hp. Subsequently, in some versions of this aircraft, more productive piston engines were used, however, this did not have a real impact on the aircraft performance characteristics. The maximum flight speed of the Harbin Y-11 can reach 220 km / h. (depending on the modification), which is not always satisfied customers.

In addition to the basic version, the Chinese aircraft manufacturers from «Harbin Aircraft Manufacturing Corporation», also produces a number of modified variants:

  • Harbin Y-11 - Basic production version of the airplane;
  • Harbin Y-11B - A modification equipped with modern means of avionics and powerful six-cylinder aircraft engines Continental TSIO-550-B, each of which is capable of thrust 350 hp .;
  • Harbin Y-11 Agricultural Aircraft - Agricultural version of the aircraft;
  • Harbin Y-11 Geological Survey Aircraft - Version of the geological reconnaissance;
  • Harbin Y-11T - Turboprop aircraft version, later became a separate model - Harbin Y-12.
