Yak-28 - Soviet jet multi-purpose military aircraft, codified in NATO as "Brewer". "Twenty-eight," made its first flight in early March 1958 years. Produced with many possible modifications, in particular as a bomber, fighter, reconnaissance, trainer aircraft and electronic warfare aircraft. His projected due to the previously created Yak-26, which became the base model. Yak-28 could become a carrier of nuclear weapons. He is the first large-batch frontline supersonic bomber in the USSR. It produces more than 10 years, and production ended only 1971 year. In the history of 1180 built aircraft, and was the most common modification of the Yak-28P.
The operation period of the aircraft
For the first time the finished serial Yak-28B was demonstrated at the air show in Tushino in 1961 year. The aircraft had been distributed throughout the Soviet Union, the German Democratic Republic, the Polish People's Republic and the Western Group of Forces. In parts of reconnaissance aviation, air defense and fighter-bomber squadrons of Yak-28 1992 year it was up. Ukrainian Air Force used it to 1994 years.
Although the model of this aircraft and was one of the most numerous, it still was not officially accepted the aircraft for the Air Force. The fact that one of the demonstration flight incident happened: the plane, leaving the supersonic, broke into pieces.
In April 66 year Yak-28 captain and lieutenant Boris Kapustin Yu Yanov had accomplished the feat. When flying on a plane to West Berlin began the problem and refused motors. At the cost of his own life pilots took the plane to the side than a lot of people saved. He was posthumously awarded them the Order of the Red Banner.
Ninth November 1975, the Yak-28B of 668-th BAP participated in the interception of IBS "watchdog". The order came after the team showed armed insubordination.
In a modification of the intelligence Yak-28 participated in the Afghan war.
The operation of the air car was quite difficult. Even in the absence of automation largely Yak-28 considered relinquished. Even before the state tests were clearly spelled out the critical capacity of the aircraft, including the corkscrew, and complex aerobatics. Nonsynchronous ignition and periodic self-termination afterburner set certain limits, therefore, be permitted to rise only in the formless maximum engine speed (DGF). During power afterburner at the time of take-off began raznotyag, which led to the catastrophe.
To protect against this situation on a plane AK-established 2A - a system of automatic exchange. She rejected the rudder when there raznotyag engines. So she retorted, turning the unit to the direction of the failed engine. But from a practical point of view, this machine was extremely unreliable to use. Because he had many accidents.
Also for the aircraft developed a powerful hydraulic flaps, because the previous one was not strong enough. As a result, one of the flaps on landing could simply release not until the end.
Yet the aircraft enjoyed great respect among the pilots because it has a high thrust-weight ratio. He could not produce weapons off almost vertically.
Also, the fuselage was very weak. The structure was designed so that at full load the fuselage begins to deform, whereby the lamp can not be closed until the end. First, we had the pilot plant with the navigator, and only then carry out refueling and weapons.
The design of the Yak-28
The aircraft is designed as a cantilever high swept empennage and wings. Bicycle gear with the front and rear racks ventral and two additional supporting struts at the wingtips.
The basis of the power plant consisted of two Turbojet R11AF-300, which were previously installed on the MiG-21. This modified engines, they were later renamed R11AF2-300. They were placed in nacelles under the wings. Fuel tanks together in (6 pieces). In addition, two more were suspended.
Among the equipment highlights installed radar "initiative-2», autopilot AP-28K1, advanced bomb optical sight OPB-116. In the reconnaissance version installed WLAN "Bulat" side-on view. Some specimens were equipped with radio range-finder station "Lotus" (DBS-2S) and radio navigation RSBN-2 «Code». The modified Yak-28, which supply various interference equip stations "beans", "Lilac-PN" and "Bouquet".
For the reconnaissance aircraft of the proposed system by type of AFA. During the night of shooting using the camera on-YA7 and 2 flash SDA-2.
Almost all of the options, except the interceptor had a location in front of the navigator pilot. Its cabin has been glassed. The Yak-28P navigator and pilot stationed with each other, the lantern was also common. To enhance the security established 5MN K and K-7MN - ejection seats.
From the weapons used gun HP-23 (in future replaced by GSH-23), ammunition - 50 shells. The bombs were placed in gruzootseke fuselage, because of what he could carry almost any type of bombs (including nuclear weapons) up to 1500 kg.
Armament interceptors radically different. They had no bombs, no guns, but armed with missiles R-8M-1 class "air-to-air", having semi-active guidance system and radar sight "Eagle-D." Then, for better efficiency missiles have been replaced by P-3S.
