MiG-17. OKB Mikoyan

  • The USSR, Poland and China

  • Type: single-engine jet fighter

  • Crew: one pilot MiG-15 - further development of the MiG-15 the engine VC-1

MiG-17, which is the codification of NATO called Fresco, - Soviet fighter jet VC-1, which was developed at the end of 40-ies in the OKB Mikoyan and Gurevich. This is the first serial fighter flying at supersonic speeds, in combat mode - transonic. It was intended to replace the MiG-15. It was in service with many countries of the world and participated in various military conflicts, including the Vietnam War and the uprisings in the Middle East.

History of the MiG-17

Successful appearance of the MiG-15 prophesied its upgraded model of at least promising future.

MiG-17

The OKB-155 to improve performance agility and speed of the new upgraded aircraft began experiments to change the shape of the wing. Wing sweep received 45˚. This structure checked by blowing in aerotrube TsAGI. To ensure the alignment of the wing began to have a double sweep: 45˚ on board until the middle rib and 42˚ on until the end of the wing. On the inner surface of each console, an additional comb was added. It reduced the relative thickness of the wing, and the place is sealed interface with the fuselage.

The prototype aircraft, which has been obtained by modifying the serial MiG-15, 1-SI received cipher and another called 15bis 45˚. The plane was in the rear extension at 900 mm, increased the size of the keel and the brake flaps, ailerons and installed power ventral ridge. Swept horizontal tail leading edge installed on 45˚ level. Elliptically shaped elevators replaced semicircular. The volume of the fuel tanks is reduced to 1412 liters.

Plant number 155 working on changing the design of the MiG-15 SI-1 1949 until July of, and it lasted for lapping a couple of months.

The first modernized version hoisted into the air 1.02.1950. Supervised flight test pilot Ivan T. Ivashchenko. 17.03.1950 first copy of the SI-1 crashed. At the height of 5 thousand. M plane began to dive abruptly and collided with the ground. The pilot did not survive. The second plane was factory name SI-2. It test pilot GA Gray has identified the cause of the fall. It was the destruction of the elevators in the state of flutter stabilizer.

Experienced aircraft C-SI-01 and 02, in which state tests were carried out, were obtained by changing the serial MiG-15bis in 1951 year. As part of the on-board equipment equipped with a system of recognition of SRO-1 «Barium-M" landing system OSP-48 and 3-radio RSIU «Klen».

In the future, in order to increase the performance characteristics of the MiG-17, it needed to equip it with more powerful engines. The prototype engine equipped with the VC-1F with afterburner. The front part of the left unchanged, like the MiG-15bis, posterior - redesigned, taking into account the afterburner. Conducted improvements aircraft fuel system. The chassis, the wing and some design elements borrowed from the SI-02. The unit has received factory index "SF."

The first flight took place on SF 29.09.1951 running test pilot AN Chernoburova. Factory testing lasted from November 1951g. February 1952 of further aircraft was transferred to the state tests.

They showed an increase in flight performance apparatus in afterburner, which allowed the effective vertical maneuvering SF in a dogfight. Nevertheless, horizontal flight did not get the expected gain speed as later explained unsuitability of the airframe of the MiG-17 to supersonic flight.

Even two power plant accident has not prevented the MiG-17 with motor VC-1F enter into service under the name of MiG-17F and to be missed in the series production of a 1952

MiG-17

Simultaneously with the creation of front-line fighter in the Yakovlev Design Bureau. Mikoyan and Gurevich had worked on the development version of the interceptor-based MIG-15. The first prototype has received factory index SP-2 and was equipped with a radar "Kite", as set out in the forward fuselage. Interceptor is equipped with more powerful electric generators, instead of the three guns, HP-23 left with two ammunition shells 90 - 120 and left - right. By plane provided installation outboard fuel tank capacity liters 600.

In the factory test version of the MiG-17 May 1951 I entered the city on state tests - 28.10.1951. At the end of this year, the State Commission issued a verdict unsatisfactory layout MiG-17 «Kite» radar.

Since March 1952 of aircraft equipment modified by installing radar RP-1 «Emerald", which at that time was recognized as the most suitable for the single-seat fighters.

Interceptor with besforsazhny engine VC-1A, radar "Emerald" and three guns, HP-23 has received factory index SP-7. One antenna locator placed on the upper lip of the air intake, for the second found a place in the central part of the fairing. Taking into account the weight of additional equipment installation of the new machine, compared with the base model, it increased 225 kg.

SP-7 managed to build a mid-July 1952 city, it dates back to the first flight of 8 avgusta1952

Installation of the radar in the nose led to a slight deterioration in the review of the cockpit, but that did not stop to approve the layout of the MiG-17 during state tests, and then to put it into production and put into service. He later received the name of a batch of MiG-17P.

In January 1954, the state tests of a similar interceptor began, which was equipped with a VK-1F engine and received the factory index of the SP-7F. Due to the new power plant of higher power, the maximum speed and climb rate increased in comparison with the MiG-17P. But the simultaneous increase in the mass of the aircraft by 250 kg lowered the range and cruiser speed of the interceptor. Tests of this modification ended successfully in April 1954 year. The fighter-interceptor was named MiG-17PF, put into production and put into service. On this aircraft installed a notification system about the irradiation of the "Siren-2", the volume of fuel in the fuel tanks is reduced by 27 liters.

As part of the weapons of different series, the following options are available: one gun H 37D, two or three HP-23.

MiG-17

Although outwardly it reminds MiG-15, in fact, the MiG-17 has a new wing with three aerodynamic baffles on the upper surface, which prevent air from flowing along the span of the bearing surface. The new wing, without constriction and with a sweep in 47 ° to the root part, significantly improved the speed characteristics.

Other exterior changes included an increase in the sweep angle of the vertical stabilizer and the elongation of the fuselage on 91 cm. Have been improved aircraft systems and equipment. MiG-17 1951 in January was launched into mass production, and modification of the F (with the engine 8K-1F with afterburner) debuted in the front air next year. This was followed by numerous modifications of the MiG-17, some were equipped with radar for use with the first Soviet missiles "air-air".

Aircraft production in the USSR was more than 8000 instances, and as in the case of the MiG-15, plus licensed copies "stamped" in Poland (1000 copies) under the designation Lim-5 / b as well, but in this case, China, under the designation J-5 / F-5 (767 copies). Now they are all withdrawn from service in all of the Air Force around the world; perhaps most of all MiG-17 is remembered thanks to its participation in the Vietnam War.
