Pioneers of Soviet jet technology: Yak-15 fighter aircraft vs Mig-9



24 April 1946, the first flights of the first two Soviet-made jet fighters: Yak-15 (test pilot MI Ivanov) and MiG-9 (test pilot AN Grinchik)

Almost immediately after the end of the Great Patriotic War, the scientific and technical elite of the Soviet Union began to develop domestic jet aircraft at an accelerated pace. The best cadres of the country's design offices were involved in the work. The rush made sense: the cold war clouds were gathering on the global political horizon. The former comrades of the USSR on the victory over fascism — Great Britain and the United States — had already created jet technology, and the capitalist powers put its production on stream. The Nazi Germany destroyed by the Allies, by the way, possessed similar equipment during the war years. Against this background, the technical gap of the USSR in this area did not even look depressing, but simply dangerous.

One of the Soviet research centers that began developing a new type of aircraft was the experienced design bureau under the supervision of A.I. Mikoyan (brother of Stalin’s Commissar for Foreign Trade) and his deputy, designer M.I. Gurevich. In the depths of the research and design organization began assembling a jet aircraft, codenamed I-300. The design bureau of Mikoyan and Gurevich, after the first letters of the names of which jet fighters began to be called MiGs, has grown these days to the aircraft-building corporation of the same name. By the end of the victorious 1945 for the country, a pilot sample of the future jet fighter was already ready, but its technical refinement stretched to the beginning of next spring.

24 April 1946 of the year from the airfield in Ramenskoye near Moscow, the first prototype of the future MiG-9 - Soviet turbojet fighter - took off. Test pilot Alexey Nikolaevich Grinchik sat at the helm. Despite his youth, he was the most experienced 11 test pilot of the first class in the USSR at that time. That is why he was entrusted with the testing of a new model of Soviet aviation equipment created in the shortest possible time - a jet fighter aircraft. The flight lasted 6 minutes was successful.

On the same day, on a new Yak-15 monoplane fighter (named after the first letters of the name of aircraft designer A.S. Yakovlev, deputy people's commissar aviation USSR industry) test pilot Mikhail Ivanovich Ivanov made the first 5-minute flight. Subsequently, he continued to test the latest examples of jet technology, for which two years later he was awarded the title Hero of the Soviet Union.

11 July 1946 of the year on indicative comparative performances decided the fate of the MiG-9 and the Yak-15: which car to start in mass production. The pilot of the MiG, Grinchik, decided to demonstrate to the persons responsible for the final decision all the conceivable and inconceivable possibilities of his aircraft and laid a very steep turn, which was not provided for by the design structure. This led to the tragedy: the plane in the eyes of the selection committee began to fall apart in the air and eventually crashed into the ground, and the talented test pilot died. Alas, exactly two years later, his colleagues were gone: Ivanov, too, died during the testing of one of the newest models of Soviet fighter technology.

The tragedy of the prototype MiG-9 decided the case in favor of the Yak-15. After the successful demonstration of the 18 in August, the Yuk-15 became the first Soviet fighter jet launched from October 5 into mass production. In just two years from the moment of launch, the 280 of such vehicles, received by the USSR Air Force, was produced in the series.

In the Soviet Union, the Yak-15, produced by an aircraft factory in Tbilisi, was considered a transitional type of aircraft and was used exclusively to retrain flight personnel from the previous piston fighter types to more advanced jet ones. Citizens of the country Yak-15 was first massively demonstrated at the May Day parade in 1947, when fighters flew over Red Square.

However, although the Yak-15 was the first Soviet jet, they did not forget about the MiG either. Constructive flaws were promptly eliminated as the air force mastered the new model. Two years after the first flight of the MiG-9 to the USSR, the X-NUMX of such aircraft was launched at the Kuibyshev aircraft plant. Of these, more than half (602 units) were soon transferred (as Soviet pilots mastered the new technology) as a friendly gesture to China, which, after the victory of the communists in the People’s Liberation War, embarked on a course of socialist development.

Both the Yak-15 and MiG-9 opened for pilots a new period - the era of jet aircraft, technology of fundamentally different capabilities and speeds than the one that was available to Soviet aces earlier. After the creation and introduction of combat jet fighters into production, the Soviet Union was able, in the shortest possible time, using its own forces and means to eliminate the dangerous technical gap between the leading world powers. The airspace of the USSR was now under the reliable protection of the elite of the Soviet pilots who had been trained on the latest flight models of jet technology.

    The article can be characterized by one sentence - our first serial jet aircraft were called Yak-15 and MiG-9. On the second photo is given MiG-9M, and this is a slightly different song. In 1946-48, 602 MiG-9, Yak-15 were produced -280 copies therefore somehow it is not clear how: .. "The tragedy with the prototype of the MiG-9 decided the case in favor of the Yak-15" ...?
    In general, the article is not about anything.

      article completely did not reveal the essence of the problem
      and the problem was to create an adequate jet engine.
      An engine (or its prototype) for an English meteor was created before the war.
      the Germans had several engines during the war, but they were damp.
      The Americans, with British help, received the engine by the year 43.
      and the USSR did not have a suitable engine. There were captured engines from the Germans, but we had to move on. And this lag was very painful until the purchase of 2 advanced Derwent and Nene engines in England in 1947, which made it possible to make the Mig15 and even out the chances.

        Yes, I probably agree, because with the introduction of the reactive era, a lot of previously unknown, or only in the theory of known problems related to increasing speed came by example. I remembered the story of my grandfather about the tests of one of the very first jet aircraft of the USSR. The fact is that to control piston aircraft, up to 700 km / h (let's say), there is enough muscle for a person and, accordingly, hydraulic boosters were not installed on piston fighters. And from certain speeds it is impossible to move the steering wheel moving the ropes. And this happened during the tests. The plane went into a stupor and the helm did not obey. Thank God, a test pilot with good physical characteristics was sitting at the helm, as his grandfather, a hefty Caucasian, said, and he still managed to level the plane with all his might shortly before he crashed into the ground. In general, then, after all, the USSR can be said to start from scratch, although they got a lot of technologies, both from Germany and the allies. But without basic science, the infrastructure of education, that is, its engineering school, which only from the late 50s began to gain momentum, we tried a lot, a lot of things by typing.

          IL-62 is the only heavy jet in the world, which carried out manual booster control. So much more depends on the designer.

    Yak-15 with MiG-9 did not compete. The first is a light interceptor, the second is a heavy interceptor / drummer.

    Along with the Saab 21R Swede, this (Yak-15) is the only case of a successful alteration of a piston aircraft (Yak-3) under jet thrust, especially since the piston engine was put on the Swede until there was a jet engine.

          Do not confuse the general designer (manager) with the "great" aircraft designer - even before the war, Yakovlev left for a leading position (in the People's Commissariat of the aviation industry) at Stalin's insistence and took only an indirect part in the development of most aircraft. Although the planes were named after the first letters of the Civil Code. The task of the general designer was to organize the process, choose to appoint a leading or chief designer and the head of the departments and push through the financing of the project.
          The same Mikoyan after the institute fell into the closet of Polikarpov (although his historiographers swore by his mother that he did not use family ties), although he did not have the experience of designing to claim such a responsible post. Subsequently, the entire design part was drawn by Gurevich, and Mikoyan - organizational or fashionable to speak - the general leadership. Although many historiographers indicate that Mikoyan was very good at mastering the topic and making technical decisions.

    ...... Yak-15 was first massively demonstrated at the May Day parade in 1947, when fighters flew over Red Square.From the biography of aviation lieutenant general P.S. Akulenko ...... At the Pervomaisk air parade in 1947, Lt. Col. P.S. Akulenko flew leading the top five, in fact directing the entire system of aircraft. For the parade, the government approved a system of 2 columns of 50 MiG-9 and Yak-15 aircraft. The columns were built of fives. The speed was set so that the flight of a large group provided complete safety and the ability to maintain the system. As a result of the calculations, the depth of the combat order when flying at an altitude of 500 meters was about 15 kilometers, and the flight took about 3 minutes.

    On May 1, all 100 jet fighters took off in fives from 2 airfields, gathered in 2 columns of 10 fives each, followed a given route and flew in clear formation over Red Square. At the same time, the entire flight of the MiGs took 40 minutes, and the Yakovs - 23 minutes. On May 16, 1947, by the decree of the Presidium of the Supreme Soviet of the USSR, 163 aviators were awarded orders of the Soviet Union. 5 people were awarded the Order of Lenin - P. Akulenko, E. Zyryanov, I. Koshel, A. Kuzminsky and N. Sbytov, the Order of the Red Banner - 93, the Order of the Red Star - 65 ..... (C).

        Even during the war, the Americans built a jet fighter, but with British engines. And our post-war were, yes, German. The article somehow modestly kept silent about this key point. Moreover, the Yak is simply an alteration of a piston aircraft for these German jet engines. MiG - a new design. But he had problems - it was dangerous to shoot from his weapon for himself, especially from the main caliber, since the engines stalled from the exhaust of the guns. The trunks were near the air intakes. The first pancake is lumpy. In the photo in the article, a seemingly modernized version with a different arrangement of guns.

          In the USSR there was no heat-resistant alloy for the WFD, so the Cradle's engine melted at the stand. In order for this alloy to not get into the USSR, German jet planes did not fly over it. The British had a similar alloy, but they did not share it with the USSR.

          The turning point in the post-war Soviet-German scientific and technical cooperation in the military sphere was October 22, 1946. On this day, the operation of the mass removal of German scientists, engineers and workers to the USSR began. The general management of the operation was carried out by the deputy of Beria I.A. Serov. The transportation from Germany to the USSR of seven thousand German specialists of various profiles was carried out clearly and efficiently. Two weeks after the start of the operation, all Germans were distributed across 31 enterprises of nine Ministries at various points in the Soviet Union.

          "Series" BI? What series? A purely experimental car. After the death of Bakhchivandzhi, the topic was closed.

          And about the "mass export of specialists, there were no" - everything was somewhat different. It was, however, on a much smaller scale than that of the "sworn allies": they just hurried up earlier. And if the cards were folded differently, you look, von Braun would have worked with Glushko and Korolev.

And, by the way, the British also won the engine for the second generation in cards. You can twist that they themselves did not come up with anything. But look at the modern "dryers", "flashes" and "yaks". And ask yourself, where are the German and British fighters?

    The era of development of jet aircraft is a very interesting period in aircraft manufacturing.
    Many achievements have been made.
    In Korea, our pilots showed themselves worthy thanks to the high combat qualities of our aircraft. These were already MiG-15s that were superior to American aircraft of this class.

      In Korea, our pilots showed themselves worthy thanks to the high combat qualities of our aircraft. These were already MiG-15s that were superior to American aircraft of this class.

      This is how Evgeny Pepelyaev, a direct participant in the battles in the skies of Korea, described our MiG-15 and American F-86 "Saber".

      As a participant in the air battles of the MiG-15 and MiG-15 bis fighters with the F-86 Saber fighters, I can evaluate the combat capabilities of the MiG-15 bis in comparison with the F-86 fighter.
      The MiG-15 bis fighter, in my opinion, had small advantages over the F-86 in vertical maneuver, in the ceiling, height and weapons, inferior in horizontal maneuver, critical speed and range.
      So, the critical speed: MiG-15 bis - 0,92 M, after which there was a “felling” - the aircraft became uncontrollable; F-86-0,95 M, after which the shaking began. Armament: MiG-15 bis - 3 guns (one 37 mm and two 23 mm), sight - semi-automatic; F-86-6 machine guns 12,6 mm, sight - automatic with a range finder. Vertical speed and ceiling. - MiG-15 bis - the vertical speed is slightly higher, the ceiling is 16 m; F-000 - the vertical speed to a height of 86 m is equal, then lower, the ceiling is about 7000 m. In the horizontal maneuver: MiG-15 bis is weaker; F-000 - turn time is slightly less (good wing mechanization). In flight range: the F-15 has approximately 86 km. Compared with the Saber, a significant drawback in the flight characteristics of the MiG-86 is the very poor glide of the aircraft. Gliding a plane, especially in aerial combat, is very necessary for the pilot, in some cases when shooting at an enemy’s plane, and especially when the enemy is shooting at your plane. Electronic, flight and navigation equipment on the F-1200 aircraft is more advanced than on the MiG-15 bis.
      Comparing the combat capabilities of the two aircraft, we can say that the characteristics of the fighters are very close. Therefore, the success in the aerial combat of the MiG-15 bis with the F-86 depended only on the skill and courage of the pilots, the choice of maneuver and interaction in a group battle.

    The Me-262 glider was already ready in the spring of 1941. Before refinement of the regular BMV-003 turbojet engine, tests were carried out using a Yumo-210 piston mounted in the nose of the fuselage. The first flight with the BMV-003 was completed in April 1941, with a more powerful and reliable Yumo-004 in July 1942.

      I will add perhaps the Fritz guided bombs and the T-5 guided torpedo for submarines - long-range aviation with bombs and submarines that fear no one would rip the Allied fleet to shreds.

        Yes, yes, and Germany would have clearly had a quiet rear - England would have gone to peace one way or another (they even thought about it when they were bombed by the Fau), and the United States would simply not get involved in the European War.

          You simply do not know - the United States actually got involved in the European war even before Hitler attacked the USSR. For the actions of the Roosevelt administration cannot be called otherwise than participation in the war. Judge for yourself: the convoy of British goods by USN ships with the continuous expansion of the zone of permitted attack by enemy ships (give the Yankees free rein - they would move the Neutral Patrol line to Ireland in general), build ships for Royal Navy at American shipyards (up to escort aircraft), open supply to Britain military equipment and weapons (including the production of British weapons at American enterprises), the construction and reconstruction by American firms of military bases on the Islands, the occupation of Iceland by the US Marine Corps with the change of previously located British units there, permission for incumbent officers to serve as volunteers in the British units without dismissal from service, and, like a cherry on the cake, sending a joint commission in the spring of 1941 to inspect the Islands and select a place for American bases.

          The United States planned to legally formalize its entry into the war until 1942. For they surrendered Britain and united Europe under the Germans, they did not need them - in the role of master of post-war Europe, they already saw themselves.

        Yes, why would?
        We tried to make a "blitz bomber" out of the Me-262 - try to hit the ship exactly with an unguided bomb, and with topmast bombing the jet plane loses its advantage - speed.
        Allied air superiority on D-Day was overwhelming — no fleet would have been torn to shreds — an idle fiction. The cover of the invasion fleet was very dense.
        According to the memoirs of German pilots - it was impossible to break through even scouts.

    About nothing ...
    Something unintelligible is generally written about the causes of Grinchik's death:
    “On July 11, 1946, the fate of the MiG-9 and Yak-15 was decided at demonstration comparative performances: which car to launch into mass production. This led to a tragedy: the plane began to fall apart in the air in front of the selection committee and eventually crashed into the ground, and the talented test pilot died ... "
    For comparison, the description of the death of Grinchik from an eyewitness - I. Shelest ("I'm flying for a dream"):
    "... He was approaching the airfield from the side of the factory chimneys of the village, heading along the line of hangars. Presumably, he wanted to" check in "- to pass at a height of fifty meters, as he liked to do after a successful flight. The MIG approached us, accelerating smoothly In front, it looked like a glider: a narrow strip of wings, above it in the center - a cross of the tail. Growing up before our eyes, the plane left a slightly noticeable trail of smoke. So it missed the area of ​​slender pine trees and was now rushing over the grassy field to the left of the runway The fuselage under the wings is already clearly visible - like a flattened letter F. One can also distinguish the pilot's lantern ... But what is it?
    We saw how a small object separated from the MIG and, gleaming, began to fall ... As if a scrap of newspaper thrown out of the express window ... Behind this and m the MIG slowly began to tilt to the left. More, more ... What is he crazy ?! I also wanted to believe that the pilot, at a low altitude, had started a classic controlled barrel ... But my heart went cold. And it ended completely when the plane tilted its nose from the upside-down position with the wheels and rushed to the ground ... “Damn moment! Not necessary! What for?! S t and about in and with b! " The MIG disappeared behind the roof of a distant building near the railway line, in order to rise to the sky almost at the same time as a huge black cloud with a boiling flame inside ... "

    Based on the version of the author of the material, Grinchik is simply an irresponsible gouging that somehow does not fit with his qualifications and experience mentioned in the material ... Something I have more confidence in I. Shelest.

      In my opinion, you did not refute, but supplemented what the author of the article said. I don’t think that flying above Grinchik’s land and collapsing into parts of the plane from overloads is a clear proof of the pilot’s irresponsibility. Especially experienced, otherwise they would not have been entrusted with the high ranks to demonstrate at that time the most modern than the USSR had at that time. My opinion is that the plane was finished exactly to the date indicated by the authorities, because of which the plane was not so crude, it was generally impossible to land a person on it. Could MiGs refuse and move the deadlines? More likely not, fear of the authorities was stronger than the risk of destroying the young pilot. No wonder technical progress was fully revealed only from the late 50s.

        In my opinion, you did not refute, but supplemented what the author of the article said. I don’t think that flying above Grinchik’s land and collapsing into parts of the plane from overloads is a clear proof of the pilot’s irresponsibility.

        "After landing the Yak-15, A.N. Grinchik flew to the I-300 (F-1) in his twentieth flight. The plane easily took off from the ground, gained an altitude of about 3000-3500 m, then dropped to 450-500 m and above The airfield began to perform various maneuvers.When performing sharp turns on the car, a significant overload was felt, since when observing from the ground it was clearly visible that at that time clear contrails were coming off the wing ends. After that, the pilot turned the plane down and from the side of Kratovo decided at an altitude of 100-150 m, fly over the airfield at high speed.
        When approaching the beginning of the airfield, the plane suddenly flinched. At this moment, two objects separated from him and he, turning over through the right wing, went into the dive back and at the edge of the airfield crashed into the ground and exploded. Test pilot A.N. Grinchik died. The total raid of the first instance of the I-300 at the time of the disaster was 6 hours 23 minutes. In the presence of Chief Aviation Marshal K.A. Vershinin, at the beginning of the aerodrome near the runway, a detachable wing front part detached in the air with a transitional fuselage and the end part of the left aileron was selected.
        The disaster investigation revealed the following. The removable part of the front wing toe (windshield) with a transitional gap to the fuselage was provided to provide an approach to the ailerons control rods during operation, as well as to access the fuselage through the hatch in the area. To ensure easy removability, the lobovik was mounted to the front wing spar with a coupling bolt and to the eye fixed to the fuselage with a special pin. At the same time, the ailerons control rods passed over the coupling bolts.
        When conducting static tests, the fastening strength of removable windshields was not in doubt. However, when conducting statistical tests, wing deformation during flight overloads in combination with oncoming high-speed pressure was not taken into account. As a result, during the flight, large overloads arising during the execution of sharp turns led to the deformation of the wings with a significant deflection of the wing consoles up. Along with this, and under the influence of high-speed pressure, the pin of fastening the left wing wing protector to the fuselage disengaged and the wing link began to deform upward, bending the coupling bolt around the left aileron control rod. At the time of the flight of the aircraft at low altitude with high speed, the left wing wing protector strongly lifted to the top and cut the left aileron thrust with a tightening bolt, and when the bolt burst, the wing wing pulled off the wing. The plane became uncontrollable, and from a large overload, ailerons, elevators and rudders began to collapse.
        Thus, the main reason for the disaster was the unsuccessful fastening of the removable wing lobes. In this regard, on other machines, the attachment of the lobes was changed, they began to be fixed with screws along the entire perimeter of the connector. "
        But about the "pilot's irresponsibility" you are in vain ... At the shows in front of the big bosses, all elements of the flight are worked out in advance and recorded in the flight task.

    Citizens of the country Yak-15 was first massively demonstrated at the May Day parade in 1947, when fighters flew over Red Square.
    I want to clarify a little about this parade:
    In the spring of 1947, the Air Force received more than fifty Yak-15s, some of which either had no weapons at all, or were equipped with only one gun. Their mass demonstration took place on May 1 over Red Square, when 100 jet aircraft (50 Yak-15 and MiG-9 each) flew by links.http://mreadz.com/read349134/p43. In addition: In the same year, aerobatics on jet aircraft was demonstrated for the first time at an air parade in Tushino. Colonel I. Polunin spoke on the Yak-15, and behind him a whole cascade of figures was demonstrated by the link of Hero of the Soviet Union Colonel N.I. Temple. In 1948, Yu.A. mastered aerobatics on various jet aircraft. Antipov, A.G. Proshakov and other air force pilots. To Aviation Day, twice Hero of the Soviet Union, General E.Ya. Savitsky organized the aerobatics five on the Yak-15, which he led, including the famous pilots: P. Sereda, N. Hramova, V. Efremova and P. Solovyov. They marched over the airfield in the "wedge" formation and performed several aerobatics. There are documentary motion pictures on which you can see the Yak-15 red.

    Let me ask you for the EVIDENCE that the NKVD could sew any article. And I want to remind you of such a trifle as the COURT. It is the court that makes the decision.

    Judging by YOUR statement, you did not communicate with the parents who lived in that era, but you know about the terrible times from the stories of their children. Well, where is "firsthand" here? Moreover, I am convinced that if you dig up your parents, it turns out that they too were broadcasting not about their own experience, but about what they had heard from Baba Mani, to whom a neighbor told how the NKVD tortured the sister of her second cousin.

    I admit that your company employs engineers "for years". How old are they? 75? Hardly more ... Ie they were born around 1940. The NKVD ceased to exist in 1946. When did 6-year-old children learn (and realize) about the atrocities of the NKVD ?!

    You have to KNOW, and you don’t have to take it, the ends do not meet.
