KR-860 - project double-deck wide-body aircraft, which was developed by the Sukhoi Design Bureau in the cargo-and passenger version. The first acquaintance with him was held at the Air Show "Le Bourget-99».

The history of the development of the CD-860

The development of KR-860 "Wings of Russia" began at Sukhoi Design Bureau in 1997. The project was led by A.Kh. Karimov, Chief Designer. General leadership fell on M.P. Simonov. In the development process, the latest achievements in aerodynamics, automatics, and structural materials were applied. In order to achieve the optimum degree of technical risk and the cost of development, they completely abandoned unverified technical solutions and concepts, exotic aerodynamic schemes. Aircraft aerodynamics were worked out jointly with TsAGI. They managed to achieve a high aerodynamic quality, the indicator of which was 19,5. For the first time on the domestic aircraft to achieve parking dimensions were used folding console wing. For the first time the project was demonstrated at 1999 in Le Bourget at the Aerospace Show. The Kazan aircraft plant is expected to be mass-produced.

KR-860

The KR-860 airplane is nothing more than a free-carrying low-planer. The vitreous wing is folded in the parking lot. The chassis is multi-bearing, retractable. The power plant consists of four General Electric turbojets CF6-80E1, located on the pylons under the wing. However, there is a variant with eight engines NK-93 or PS-90. The control system is digital, electro-remote with multiple redundancy. In the basic version, the aircraft is intended for 860 passengers in salons of three classes, which are located on two decks. For landing and landing, the aircraft has built-in descending ramps. In the cargo version, the KR-860 has a stern ramp and a forward fuselage that can be lifted. There is also a cargo-and-passenger variant.

The company for the development of aviation technology OKB. BY. Sukhoi led the design work on passenger aircraft super-large sizes to 860-950 passengers in the frame of the program entitled "Civil Aircraft". KR-860 intended for high-speed flight, he developed a speed 1000 km / h on intercontinental and transcontinental flights.

KR-860 - airliner normal aerodynamic scheme with cheyrmya American engines that are on the pylons under the wing.

Two deck design will be used in the cabin. This is directly related to the fact that the airplane has to fit into the existing airport buildings and runways around the world.

Like other "air heavyweights" airliner KR-860 should be based on the ground of the first class. But it worked out measures aimed at improving its takeoff and landing characteristics, that for transport and military transport versions is especially important.

To date, prospective variants of the power unit KR-860 are being studied. Negotiations were conducted with the company "General Electric", which created the TRDD SR6-80E1 (it is planned to equip them with Western European ACWR). Experts assumed that in the future Russia will receive engines, as well as a license for their development at one of the country's enterprises. Soon, the variants of the power plant were considered, which consisted of four "sparks" of domestic engines NK-93 or PS-90. It is assumed that the more economical, despite the higher weight, eight-engine power plant will appear on cargo variants of the aircraft, which will primarily focus on domestic transportation. Perhaps the equipment of the aircraft and the Pratt-Whitney PW4168 and the TRLS "Rolls-Royce" of the type "Trent".

KR-860

For aircraft KR-860, which is used for the transport of liquefied natural gas, the best option seems to equipment by its engine, which runs on gas transported (in our country there is quite a big technological advance for the development of such engines). Using the latest advances in avionics has made it possible to reduce the crew to 2-3 people. KR-860 offered to equip a digital wire control system (do not forget that Sukhoi is considered one of the leaders in the creation of FBWCS worldwide).

In the development of the CD-860 special attention is paid to ensuring the survival and safety of passengers. In this direction it is planned to carry out a whole range of research.

It is worth noting that the program is the creation of "Wings of Russia" has just started to take the first steps. But it is already possible to note its support for large regional leaders and politicians, such as Vyakhirev (Head concert "Gazprom) and Mintimer Shaimiev (president of Tatarstan).

The creation of the "Wings of Russia" is a complex and ambitious task that can be effectively solved only with the support of the State Duma, the Government of the Russian Federation, the national capital, the Federation Council. But its successful decision will positively affect the economic situation in Russia, open a "second wind" for the gas and oil industry, will solve the crisis with the supply of energy to various remote regions of the country and the problems of "northern deliveries". KR-860 - a new vehicle that is necessary for domestic freight. They can bring tangible profits to the country.

Construction KR-860 - it still support the domestic aviation industry, which is suffocating without a "real" work, and large orders. It is hoped that the new airliner, no matter what the difficulties, able to climb into the sky, to prove to everyone that Russia, as before, there's wings.
