Mig-17 Fighter Aircraft Details

In the late 1940s and early 1950s, the United States and its allies in the North Atlantic Alliance were actively preparing for a new world War, and the Soviet Union was forced to take vigorous measures to create means of protecting the country from air attack. One of the main ones among them were high-speed fighters with powerful onboard weapons, capable of intercepting and destroying enemy thermonuclear bombers in any weather, day or night, before they approach the target. The success of the MiG-15 allowed OKB-155 A. I. Mikoyan and M. I. Gurevich to get from the top leadership of the country carte blanche for further improvement of this machine.

OKB A. I. Mikoyan launched work on the modernization of the MiG-15 and the installation of a new wing with a sweep angle of 45. The production MiG-15bis aircraft with a VK-1 turbojet engine was finalized. The upgraded vehicle, known as the MiG-15bis 45, also received a new corporate designation “SI-01”. Its most important difference from the original version was a significant (10°) increase in the sweep of the wing. The improved fighter received a new wing of reduced thickness with a 45-degree sweep and a modified cross-section (previously tested in TsAGI wind tunnels and on flying models) with three aerodynamic crests, which improved the flight characteristics of the aircraft. The rear fuselage was lengthened by 900 mm; the brake pads and keel were enlarged; the ventral ridge and aileron power steering were installed. The horizontal tail was redesigned with a sweep angle along the leading edge of 45 and, in addition, a ventral ridge was installed. The fighter’s armament remained the same as that of the MiG-15bis. Work on the production of the SI-1 lasted at plant No. 155 until July 1949, then it continued to be refined for several more months.

The first flight of the prototype took place on January 14, 1950, and, at the beginning of factory tests, it was established that the maximum speed of the SI-01 aircraft with an engine of the same thrust exceeds the speed of the MiG-15bis by 40 km/h, and on February 1 of the same year at an altitude of 2200 m, the aircraft showed a speed of 1114 km / h, that is, exceeded the speed of sound. However, on March 20, during the next test flight, the SI-01 aircraft crashed. It took more than a year to find out its causes (the destruction of the elevators when the stabilizer flutters), eliminate these shortcomings and build the next SI-2 aircraft. After all the improvements, the aircraft in April 1951 was transferred to state tests at the Air Force Research Institute, which ended on August 8. During the tests, it turned out that it is indeed significantly superior to the serial MiG-15 in terms of speed and rate of climb, although it is somewhat inferior to it in horizontal maneuverability and take-off and landing characteristics. However, in the early 1950s, these indicators were not significant, the main thing was to achieve maximum speed, especially when climbing, which reduced the time to intercept enemy bombers. In the final Act of testing, the commission wrote:: “The modified MiG-15bis aircraft with a 45° wing sweep and a new tail unit has an advantage over the production MiG-15.” The new front-line fighter was recommended for production and adoption. Already in September of the same year, 1951, it was put into production under the designation “MiG-17”. Its production was soon established at 5 aircraft factories at once: in Gorky, Kuibyshev, Tbilisi, Novosibirsk and Komsomolsk-on-Amur, largely due to the fact that the MiG-17 practically did not differ structurally from its predecessor. During the production process, the design of this fighter was repeatedly refined and later, on the basis of the MiG-17, several combat modifications were built.

The MiG-17 was an all-metal medium-wing fighter with a swept wing and tail. Fuselage-semi-monocoque type, round cross-section with a transverse connector in the tail section for access to the engine. Along with the wing, the sweep of the keel and stabilizer was also increased. The landing gear, controls and cockpit were almost identical to the MiG-15, as was the onboard armament, which consisted of two 23-mm HP-23 guns and one 37-mm H-37D. To monitor the results of shooting and training targets on the MiG-17 mounted photokinopulemet S-13. On the external suspension, the aircraft could carry two bombs of 250 kg caliber, and the bombing could be carried out both from horizontal flight, and from a dive or from a cabriolet.

Armor protection consisted of a front armored glass lantern 64 mm thick; armor plates in front of the pilot’s cabin; armor plates and an armored seat headrest. The MiG-17 was equipped with a VHF radio station RSIU-3 “Maple” (later replaced by RSIU-4V ” Oak “or R-800); an automatic radio compass ARK-5 “Amur”; responders of the SRO-1″ Barium-M ” recognition system; equipment for blind landing OSP-48 and a periscope for viewing the rear hemisphere. Some of the aircraft were equipped with SRD-1M radio range finders. The MiG-17 powerplant consisted of an upgraded VK-1A turbojet engine with a centrifugal compressor with a thrust of 2740 kg, which provided a speed of up to 1094 km / h at an altitude of 2000 m. Subsequently, starting with the MiG-17F aircraft, and on all subsequent series – P; PF; PFC, VK-1F engines with an afterburner were installed. When it was turned on, the thrust increased to 3380 kg, which significantly increased the rate of climb of the aircraft, significantly expanding the possibilities of its vertical maneuver in air combat. At the same time, the increase in speed in horizontal flight, on the contrary, increased slightly, as it turned out later, due to the fact that the MiG-17 airframe was not adapted to supersonic flight. Thus, the MiG-17F became the first Soviet serial front-line fighter to fly at the speed of sound. The MiG-17 gained an altitude of 5000 m in 2.5 minutes, and 10,000-in 6.6 minutes. Its ceiling was 14,500 m. With a fuel reserve in the main tanks, the flight range of the MiG-17 fighter reached 1,290 km, and with two outboard tanks with a capacity of 400 liters each – 2,060 km.

Mikoyan’s design team paid special attention to improving the MiG-17 as a fighter designed to search for and conduct targeted fire on enemy aircraft in the absence of visibility day and night. For this purpose, the on-board radar station RP-1 “Izumrud” was installed on the MiG-17P interceptor aircraft, coupled with the ASP-3N sight. The station had two antennas: a search antenna located in the upper lip of the air intake, and a sighting antenna located in the central air intake rack. When approaching a detected target up to a distance of 2 km, the sighting antenna was automatically turned on, which made it possible to make accurate aiming. With normal visibility, the locator was turned off, and the pilot used the usual ASP-3N sight. In the future, this aircraft, in the version of an all-weather fighter-interceptor, was produced with a forced engine – under the designation “MiG-17PF”. Its maximum speed at an altitude of 4000 meters was 1121 km / h, and the ceiling was 15,850 m. The fighter gained an altitude of 5000 meters in 2.5 minutes, 10,000 meters – in 4.5 minutes. The equipment was significantly expanded and updated, in particular, the aircraft received the Sirena-2 radar warning system. Its armament (depending on the series) was either two 23-mm HP-23 guns and one 37-mm N-37D or three 23-mm HP-23 aviation guns. After the creation of air – to-air guided missile weapons, the MiG-17’s ability to intercept and destroy enemy aircraft has significantly increased. Fighters with such weapons, which consisted of four K-5 (RS-1-U) or K-5M (RS-2-US) air-to-air guided missiles, received the designation “MiG-17PFU”. The characteristics of all variants of the production MiG-17 aircraft included: reliability; relative ease of piloting and unpretentiousness in maintenance on the ground. The control of this fighter was within the power of an average qualified pilot. A total of 8,045 MiG-17 fighters of various modifications were produced in the Soviet Union from 1951 to 1958.
