Tu-126

 Tu-126 Engine. The weight. story. Range of flight. Service ceiling

With the detection of air targets on the distant approaches can best handle planes, having armed with powerful surveillance radars. The aircraft for this purpose should have a great flight time - 10-12 hours, practical ceiling 8000-12 000 m and the considerable range of flight. By the end of the 1950s. most suitable aircraft been KB AN. Tupolev. According to the government decree number 608-293 from 4 July 1958 g. the Bureau was instructed to design and build complex AEW for the detection of air and sea targets on the basis of the serial bomber Tu-95. Subject to the Bureau was designated plane "126", official - Tu-126 (plane "L").

The analysis and the first evaluation projects CB shown, that create a complex based on the Tu-95 inexpedient, more rational it would be to use passenger aircraft Tu-114. The fuselage is TU-114 which can accommodate a large number of electronic equipment, ensure her normal temperature conditions on board and to create favorable conditions for long-term work crew, which was to consist of two shifts at 12 human.
At the beginning 1960 g. Air Force identified the base plane, which must be installed equipment AEW - based on serial Tu-114. 30 May 1960 g. There was a new government decree USSR № 567-230, wherein the plant № 18 It was instructed to build a Tu-126 on-board equipment "Liana" complex. Radar "Liana" was established in the Moscow Scientific Research Institute of Instrument-led A.T. Metelsky. The antenna station was placed in a rotating dorsal fairing, Radar is able to detect air targets at ranges up to 350 km, a large sea targets - at a distance of up to 400 km. The aircraft to be used on the Arctic theater, where there was no continuous radar.

on the aircraft Tu-126 work went fairly quickly, preliminary design was approved in August of I960, and in December the aircraft layout was adopted. The most significant changes to the airframe of the Tu-114 has undergone a fuselage. The bow of the fairing installed astrosekstantov heads, under the fuselage - the air intake cooling system radar "Liana", wherein the antenna is located in rotating fairing diameter 11 na pilot Jashyl ​​carpet. Antenna revolved at a speed in flight 10 rpm. There is a problem with an order for a large bearing rotating assembly, in a country such did not exist. Thanks to the energy AN. Tupolev production of these bearings were spent in Moscow. Inside the pylon for maintenance had the hatch, and the fairing height allowed to move freely in it man. The passenger cabin of the aircraft base has undergone a major change, front and middle part of the fuselage panels were busy with jobs operator, located at the rear of radar and communication units. The aft fuselage to improve directional stability at the bottom an additional keel, and secured to the ends of the stabilizer antenna tuner "Harp".

The first prototype of the Tu-126 was built in the fall 1961 g. The first flight made 23 January 1962 g. with a crew led by pilot-is-the auger IM. Suhomlynыm. The first seven test flights were carried out with a model "Liana" station. Flight testing continued until April 1965 city, although in November 1963 g. the aircraft was put into production. The characteristics of stability and controllability of the Tu-126 radar top practically did not differ from the characteristics of the Tu-114. A total of nine cars built, on production machines in the aft mounted container with equipment REP, and in the bow - refueling system in flight, similar to those used on the Tu-95. The disadvantage of radar "Liana" was the inability to identify targets on the ground background, and the emergence in the 1960s,. aircraft, can penetrate to the target at low altitude, made complex Tu-126 virtually helpless. AT 1984 g. Tu-126 aircraft was removed from service, replacing the new A-50 with the "Bumblebee" radar.
