Yak-40 (NATO reporting: Codling - «Small cod") - passenger aircraft used by local airlines, developed in the Soviet Union in 1960-ies.
Yak-40 the world's first jetliner for local airlines. He was the first Soviet aircraft, which took place on airworthiness certification in the capitalist countries of Europe. Since the start of design to its construction was only one year. 21.10.1966 plane was hoisted into the air as a test pilot A. Kolosov. The design of the machine made for specific opportunities to take off and land on unpaved airfields.
Yak-40 is extremely simple to manage and use, was designed for flight and ground personnel with high qualifications. The plane got two nicknames: "Iron-stub" - for small dimensions and powerful motors dymlenie and "Fighter of kerosene" - for high fuel consumption. Liner is equipped with a folding ladder for the passengers, self-starter, have good handling on taxiing. All this made it possible to operate the Yak-40 on unprepared airfields. Location engines in the rear significantly reduce vibration and noise.
Total production of aircraft factories Soviet aircraft Yak released 1011-40. Series production ceased in 1981 year, but even after this mini-ships cruised along the routes of Soviet and foreign airlines. This suggests structural safety and the correct application of technical solutions to eliminate problems encountered during the development of the Yak-40.
Together with designers Yakovlev officers Minsk Aircraft Repair Plant established on the basis of an airplane flying laboratory for the segment of the economy.
The Yak-40 has been widely used in the USSR. By the middle of 70-ies they were ousted veteran local airlines IL-14, IL-12 and Li-2. Liner in the history of operation carried more than 80 million passengers to more than 300 settlements. Flawless experience with the airplane in the USSR and countries 18 forced to think about the inaccuracy of its removal from the production. AI-25 engines were replaced by more modern models, which had the best indicator of its economy, in order to increase production and exports. However, the aircraft is capable of carrying several dozen passengers, it was not economically viable, despite the fact that in the early 90-x have been large passenger aircrafts. This was the main reason for the cessation of production and operation of the Yak-40. The second reason was the retrofitting capacity of the manufacturer to build a series of Yak-42.
In 1992 of the Smolensk aircraft plant had a revision of the existing Yak-40 in the modification of the Yak-40D, which had increased the volume of fuel tanks. In 1996 the plane was equipped with an administrative option for plying on international airlines. But he was operated only in the VIP-version for charter flights in the civil was not profitable airlines. Since the beginning of the year 2000-40 Yak completely written off the Russian airlines.
Purpose of the aircraft lay in the carriage of passengers to a distance of 1500 km. Passenger capacity - up from the 27 32 people. The liner had a small cruising speed - 510 km / h. The design is simple.
The combination of a wing structure with three engines AI-25 provide good flight characteristics. Medium-sized jet engine placed in the fuselage. Reverse thrust engine is a special device that changes the direction of the flow of exhaust gases during braking. It shortened the landing roll the aircraft to 400 m. The structure of the aircraft structure includes reversible plates.
The cabin liner Yak-40 has two jobs - for the pilot and copilot. If necessary, you can place the third seat. From the cockpit offers a good overview of both pilots.
Yak-40 is equipped with a modern set of electronic navigation and flight equipment. It allows the liner to hold the flights day and night, even in bad weather. Yak-40 equipped with an autopilot AP-40, course system GMK-1G, th AGB-3K, magnetic compass KI-13, two automatic direction finder ARK-9, kursoglissadnoy landing system SP-50, low altitude radio altimeter RV-ZM. Radio communication equipment includes radio command "Pen-11» (P-860-11) or radio "Balkan-5» and "Lily-5». The Yak-40 present the efficiency of air-thermal anti-icing system.
The security system includes radiometeolokator "Thunderstorm", capable of detecting storm fronts for routing rate.
The aircraft has a resource of 30 thousand. Flight hours and service life - 25 years.
Wing aircraft high aspect ratio, direct, consists of two main consoles. Each arm has three sections sliding Embarkation vzlёtnyh-flaps and ailerons two sections. Each set of longitudinal frame console and the console spar wing structure consists of six pairs of stringers, a spar, two longitudinal walls. Cross set consists of thirty-four ribs. Casing design is made of duralumin sheets. The wing cutouts for niche where are placed in the retracted position of the main wheel and landing gear strut. Wherein the chassis is provided with wheels of large diameter and a soft damping which reduces the surface runway specific pressure and gives the possibility to use the plane on rural airfields.
On each wing there are three sections of the flaps. All sections are similar in design. Each part consists of cladding and framework. The frame is formed by stringers, spars, a set of cross-section and ribs.
The longitudinal walls consist of channel iron beams, which consists of a wall, supported by pillars, the upper and lower zones. The stringers are made of aluminum extrusions brands section.

The closest analogue is the VFW-Fokker 614 - short-haul jet airliner production of Germany. Produced in limited series, a distinctive feature - the engines located on pylons above the wings.
Interesting facts about the aircraft
The landing and landing of passengers is carried on the tail ramp-ramp, which is both a hatch cover reminiscent of aircraft cargo ramp in its design.
At Yak-40 no separate luggage compartment. Baggage pass when boarding and transported in the lobby.

According to unofficial information in the fighting, and as a result of accidents, disasters and destruction on the ground was lost 117 instances of aircraft Yak-40.
