Tu-142, which is the codification of NATO called Bear-F, - the Soviet long-range anti-submarine aircraft.
At the initial design stage of its planning for the destruction of underwater nuclear ballistic missile submarines (SSBNs) enemy patrol mode. Operated Navy to carry out long-distance radio and visual exploration of the ocean, for search and rescue, and tracking SSBN.
History of the Tu-142
In 1959 of service in the US Navy received a new SSBN "George Washington", which a year later embarked on a task to patrol the surrounding waters. In 60-ies strengthen the enemy has become even more powerful. We received five submarines "Eten Allen" and nine "Lafayette" in the ranks of the United States Army. These SSBNs could cause direct nuclear attack on the strategic objects border of the Soviet Union. The threat was incredibly sharp, because at that time to deal with the reflection of such an attack was impossible, utilizing the missile defense system.
In 1962 the USSR Ministry of Defence issued by its own calculations conclude that the most effective tool against the American SSBNs will Soviet DPLS having twice the radius of action, rather than IL-38.
For the sake of reducing the time it was decided to develop a new aircraft based on the Tu-95 RC and install it antisubmarine complex with IL-38. 28.02.1962 USSR CM Resolution number 246-86 was launched development DPLS Tu-142, which was part of the faculty of "Berkut".
Adoption of the tactical and technical characteristics agreed Chief of the Navy and Air Force 20 April and the preliminary design was ready 9.10.1963. To test complex planned to build up to 1966 years. However, it was not possible to sustain such terms. Repeatedly we had to make adjustments in the design. 17.01.1968 the Council of Ministers took the decision to prepare three copies of the Tu-142 for joint production tests in 1968g., And in the second half of this year to start public testing of the machine.
The first flight in the experimental Tu-142 (4200 board room) was carried out under the supervision of 18.06.1968 test pilot IK Vedernikov. The second copy (№4201) raised in the air 3 September and the third (№4202) - 31 1968 October g
To direct aircraft on the state tests could only 1970 city, and they lasted until 1972 At that time it was removed the requirement to ensure the possibility of the device based on the unpaved airfields, and re-equip the car chassis light and AV 60K screws having the best efficiency at the maximum flight speed. Move complex with anti-IL-38 also failed, for it had to change some of its elements, in particular the digital computer "Flame-263» .On arms DPLS Tu-142 1972 set in December, on the construction of the aircraft as a whole has taken almost 10 years.
Production of the Tu-142
Based on the external similarity of the Tu-Tu-142 and 95RTS, series production deployed on №18 aircraft factory in Kuibyshev. Power plant in the city of 1972 12 allowed to release new anti-submarine aircraft. And if you take as a whole, this plant has given the Navy Tu-18 142, including the first three prototypes. During the manufacturing process improvements have been made, and the second batch, which on №18 plant was represented by three planes, significantly different from the first series.
In 1973, the production of the Tu-142 was moved to the Taganrog aircraft factory on №86. The designers of this company also upgraded design. In particular, the landing gear was replaced with 12-wheel for standard 4-wheel from the Tu-95, improved cockpit and spent some more work on modernization. The name remains the same aircraft - Tu-142, but the technical documentation is accompanied by naming the product "VPM" - modernized "VP".
As it turned out, the Taganrog plant was not suited to the production of aircraft of this class. I had to finish building a new plant and new large runway. As a result, the construction of the first Tu-142 factory №86 completed only in 1975, the latest model released in Tu142M3 1994 During the period of mass production at the Kuibyshev and the Taganrog factory about a hundred Tu-142 different versions were built.
The design of the Tu-142
The fuselage has a circular cross section, running casing, a set of frames and stringers. From a technological point of view, the fuselage consisted of a nose portion (up to the frame №1), front sealed cabin (trowels. №1-13), the middle part of the fuselage (trowels. №13a-49), the rear fuselage (trowels. №50- 87), rear pressurized cabin (trowels. №87-93).
Front pressurized cabin - one storey. The upper part was assigned to the crew, and a significant part of the equipment, the bottom was divided into 3 technical compartment.
The middle part of the fuselage took two weapons bays, which are the means to find and engage targets (beacons, explosive sources of air, torpedoes, rockets, mines, bombs, other weapons). The fuel tank is located under the second compartment weapons.
The rear pressurized cabin equipped with gun mount with a pair of guns GS-23 and AM-23. At the top - the equipment compartment radar "Krypton".
Wing Tu-124 caisson type. The arrangement center section is integrally formed with the fuselage. The internal part of the wing consoles won sealed the fuel tanks.
Means of mechanization of the wing are the double-slotted flaps, which are equipped with electric-12M inventories.
roll control is performed by means of classic ailerons. To the right aileron Flettner-trimmer attached.
The tail unit caisson-type single-fin. Adjustable stabilizer consists of two parts, which will dock on the axis of the aircraft, and rearranged with the involvement of the ICC-3 drive. Rudders and height are partial axial aerodynamic and weight compensation. Part elevators connects the propeller shaft. To the right handlebar height-Flettner trim attached to the left - just Flettner.
aircraft Chassis - complex design of 12 wheels on each rack, which included multi-disc hydraulic brakes. In the future, the chassis has been simplified, bearing steel four-bet, such as Tu-95.
Chassis Tu-142 tricycle, has a nose support. Cleaning racks is performed in a gondola chassis, through the application of electric mechanisms MPSH-18MT.
Release the front desk is performed by the hydraulic system, and in an emergency can be done with the help of pneumatic.
