1-220 / A / MiG-11

In 1942 the ОКБ began to build a string of high-altitude interceptor prototypes (the A series) meant to oppose the Luftwaffe’s photo recon­naissance aircraft, which were able to operate with complete impunity because of their high operational ceiling. These Soviet aircraft were in fact updated remakes of the MiG-3.

The 1-220 no. 01 was first powered by the AM-38F engine at 1.250 kW (1,700 ch).

The first project was assigned the letter A and the designation 1-220. It was a low-wing single-seater of mixed construction. For the first time the ОКБ designers departed from the MiG-3 layout. All of their previous models had had the exact same span and wing area. The 1-220 was different: the radiator was moved to the wing center section (with air intakes in the leading edge and a variable shutter on the wing’s upper surface), the main gear legs were given a levered suspen­sion system, its firepower was increased. Two prototypes were built. The 1-220 no. 01 received an AM-38F, which was later replaced by an AM-39. The AM-38F generated 1,251 kW (1,700 ch) at takeoff and 1,104 kW (1,500 ch) at rated altitude, while the AM-39 generated 1,325 kW (1,800 ch) at takeoff and 1,104 kW (1,500 ch) at rated altitude. Its arma­ment included two synchronized 20-mm ShVAK (SP-20) cannons above the engine with 150 rpg.

Because flight tests and the development of the AM-39 took longer than expected, the 1-220 no. 02 received an engine that was not certi­fied and could not yet be mass produced. Its armament was also differ­ent. It was the first Soviet fighter fitted with four synchronized 20-mm ShVAK (SP-20) cannons with 100 rpg and the first to have a whip anten­na for its radio set.

The 1-220 no. 01 with AM-38F engine was rolled out in June 1943 and made its first flight in July with A. P. Yakimov in the cockpit. Tests continued through August and involved pilot P. A. Zhuravlyev. The 1-220 no. 01 with AM-39 engine was rolled out in January 1944 and

underwent flight tests between then and August. The 1-220 no. 02 with AM-39 engine left the factory in August 1944 and was first flown by 1.1. Shelnest in September.

Development of a suitable engine for a high-altitude interceptor intended for PVO regiments proceeded concurrently with the prelimi­nary design of the 1-220 and continued until the test flights ended in 1944. In the meantime, the notorious inadequacies of available engines at the edge of the stratosphere greatly complicated the work of the ОКБ. The wing loading of the 1-220 was relatively moderate and marked a significant improvement over the MiG-3 in terms of both maneuverability and rate of climb. But because no existing engine could provide the needed power, the design ceiling—the raison d’etre of this program—was never reached. At low and medium altitudes, however, the aircraft proved to be superior to the Yak and La “frontal" fighters then in use. For ground speed the 1-220 nos. 01 and 02 were between 30 and 70 km/h (16 and 38 kt) faster than the Yak-9. At 7,000 m (22,960 feet) the no. 02 was 50 to 95 km/h (27 to 51 kt) faster than the La-5. If the 1-220 had been mass-produced, it would have been called the MiG-11.

1225/ 5A

The 1-225—last model of the A series, coded 5A—was the heaviest and most powerful experimental interceptor of the family. Its preliminary design was drawn up by a team of engineers headed by A. G. Brunov, project manager. Two I-225s were built in a back-to-basics formula: they had the same dimensions and wing area as the 1-220, the family’s progenitor. The 1-225 no. 01 was powered by an AM-42B engine, the no. 02 by an AM-42FB. The latter power plant provided 1,472 kW (2,000 ch) at takeoff or 1,288 kW (1,750 ch) at rated altitude and also at 7,500 m (24,600 feet). There was a TK-300B exhaust-driven turbo­supercharger on its right side, and it drove a three-bladed AV-5A-22V propeller 3.6 m (11 feet, 9.7 inches) in diameter. The problems that plagued the 1-222 and 1-224 pressurized cockpit were solved, and the

Two l-225s were built (our photographs show no. 01). The exhaust-driven turbo­supercharger was located on the right side of the engine. These aircraft were pow­ered by the most powerful Soviet engine: the AM-42B, delivering 1,470 kW (2,000 ch) at takeoff.

size of the heat exchanger placed under the back of the engine was reduced.

Protection for the pilot was enhanced by the addition of 9-mra thick armor plate to the back of the seat, and the front and rear parts of the canopy were fitted with 64-mm thick bulletproof glass. The cockpit was equipped for instrument flying and had an ultrashort – wave transceiver.

The armament on both prototypes comprised four synchronized 20-mm ShVAK SP-20 cannons (100 rpg), two mounted above the engine and one fitted on each side. The 1-225 no. 01 built in June 1941 was a direct descendant of the 1-220 and made its first flight on 21 July 1944 with A. P. Yakimov at the controls. According to design calculations the aircraft ought to have reached 729 km/h at 8,520 m (394 kt at 27,945 feet) at engine combat rating and 721 km/h at 8,850 m (389 kt at 29,030 feet) at rated power. On 7 August 1944 Yakimov clocked up 707 km/h at 8,500 m (382 kt at 27,880 feet) at rated power. Two days later, on its fifteenth flight, the plane experienced engine failure near the ground and crashed, damaged beyond repair.

A second prototype was ordered. However, by the time the 1-225 no. 02 commenced flight tests on 14 March 1945 the MiG ОКБ had turned its attention to the 1-220 (N) and its motokompressor. In tests the 1-225 no. 02 earned the title of second-fastest Soviet piston-engine fight­ers at 720 km/h (389 kt)—unable to beat the record established on 19 December 1944 by the much lighter Yak-3U (2,830 kg/6,235 lb) pow­ered by a 1,325 kW (1,800 ch) Klimov VK-108.

The 1-225 ended all attempts to design a successor for the MiG-3 based on a single layout or structural design. Every member of the MiG fighter family from the 1-200 to the 1-225 fell victim to endless troubles with its power plant. Besides, after five years of continuous develop­ment the maximum speed of this aircraft type had increased by only 80 km/h (43 kt).

Interview: Birth of a Design Bureau

IIIS INTERVIEW WITH U. A. BELYAKOV was conducted and recorded by

Jacques Marmain in Moscow on 6 March 1991.

The MiG OKB celebrated its fiftieth anniversary some months ago. Today you hold the collective memory of this big enterprise, founded at the very moment that World War II broke out. This event having overshadowed the circumstances surrounding the birth of the OKB, can you tell us how all this started?

In early 1939 the threat of war loomed large over Europe and the USSR knew that it would not be spared. Having to face the growing power of Nazi Germany, the Party and the government implemented measures necessary to reinforce the Soviet Army, of which the VVS (air force) was a major component. At this time the lighters in service with our squadrons, the Polikarpov 1-153s and l-16s, were greatly out­classed by the Bf 109Es built by Messerschmitt. There was no time to waste. To create a competitive spirit, several design bureaus were asked to develop and build prototypes. The one with the best flying qualities and combat capabilities was to be mass-produced. Simulta­neously, the NKAP (Commissariat of the People for the Aviation Indus­try) urged the creation of an experimental construction bureau able to attract young, talented specialists.

Which manufacturers were involved in the new program?

There were nine of them: Polikarpov, Yakovlev, and Lavochkin, assisted by Gorbunov and Gudkov, Sukhoi, Borovkov and Florov, Shevchenko, Kozlov, Yatsenko, and Pashinin. All these engineers had to report on their projects personally to Stalin, who was following this program closely. This is why N. N. Polikarpov, chief constructor, P. A. Voronin, manager of the Polikarpov production plant, and P. V. Dementyev, chief engineer, were summoned to the Kremlin in the summer of 1939. The talks were heated. Voronin and Dementyev, supported by Stalin, wanted to give priority to the monoplane, while Polikarpov preferred the biplane for its handling qualities. A work crew was formed within the Polikarpov OKB to create a preliminary design (coded Kh). The crew was composed of a structure specialist, Ya. I. Selyetskiy, an airframe constructor, N. I. Andrianov, and an aerodynamicist, N. Z. Matyuk. These three men are still alive: Selyet­skiy is today an assistant to G. Ye. Lozino-Lozinskiy in the space shut­tle program, Andrianov is retired, and Matyouk is one of my faithful assistants as chief constructor. The three went to the Kremlin, where Stalin approved the project in the absence of Polikarpov, who was

then in Germany. You will notice that the name of Mikoyan has not come up yet. There is a very good reason for this: he was not aware of any of these developments. At that time Mikoyan, who was the VVS representative at Polikarpov, was in charge of producing and upgrading the 1-153.

Voronin and Dementyev were the first to believe that Mikoyan was the right man to manage the new team. They confided their thoughts to Stalin, who at first snarled and said, “What! Anastas’s brother!” and then finally agreed—"OK. It’s up to you." The two men did not choose Mikoyan at random. To them, he offered many advantages. They had noticed his spirit, his mind for organization, and his popularity in the VVS and the NKAP, and he was the brother of Anastas Ivanovich Mikoyan, member of the Politburo since 1935 and people’s commissar in various economic commissariats since 1926. But they still had to per­suade the surprised Artyom Ivanovich Mikoyan, who finally agreed to this unexpected proposal on one condition: that he could take on his old friend Guryevich as his assistant.

In the meantime, several other engineers had joined the team in November 1939. They all came from the Polikarpov ОКБ: V. A. Romodin, A. G. Brunov, D. N. Kutguzov, and one or two others whose names I have forgotten.

How did the new team succeed in winning its autonomy?

Simply by government decree. But it was quite an event because, with the blessing of the authorities, Voronin and Dementyev exploded the Polikarpov system. The ОКБ, factory no. 1, and the new team were assembled in an OKO, or design and experiment section. A. I. Mikoyan was put in charge of this OKO, assisted by M. I. Guryevich and V. A. Romodin. In November-December 1939 the new OKO attained full strength and submitted the final design of the Kh project renamed the 1-200, which was planned initially with a AM-37 engine. The 1-200 pre­liminary design was quickly approved by the central committee of the Communist party, the people’s commissariat of the aircraft industry, and the air force. The existence of the OKO was formalized on 8 December 1939.

Could you tell us more about Mikoyan, a man whose name is famous all over the world? We do not really know much about him.

Artyom Ivanovich Mikoyan was born on 5 August 1905 in Sanain, a small Armenian village. His father was a carpenter. He learned to read and write at the village school and then was sent to Tbilisi high school m Georgia.

In 1923 he was admitted to the training school of the Krasniy Aksai factory in Rostov, and the following year he was hired as a mechanic by the railway workshop in the same town. In 1925, still a mechanic, he was employed at the Dynamo factory in Moscow. In December 1928

he left the factory to do his national service. Discharged two years later, he returned to Moscow and found work at the Kompressor facto­ry He entered the air force academy named after N. Ye. Zhukoskiy in 1931. There things became much more difficult, but young Artyom Ivanovich stuck with it, became keen on parachuting, and learned to fly. In 1935 he and two fellow students used a 22-horsepower American engine to build a light sport aircraft dubbed Oktyabryonok, which apparently was quite a good flier In 1937 he passed his exams at the academy with flying colors and, his first-grade diploma in the bag, found himself representing the military client (in this case, the WS) at the no. 1 Aviakhim factory. The Polikarpov design bureau was located inside this factory, which produced the 1-153 Chaika (seagull) fighters. Mikoyan was in charge of the acceptance checks on behalf of the VYS and then was appointed the permanent representative of the customer within the desrgn bureau. He was therefore in regular contact with Polikarpov, head of the design bureau.

Less than two years later, in March 1939, Polikarpov asked Mikoy­an to help him organize and update the Chaika production line. That is where Voronin and Dementyev noticed him. You know what followed.

How was the OKB organized during the first months of its existence?

In the beginning, everybody worked like hell at producing all of the drawings for the 1-200 and preparing the assembly of three proto­types. In December 1940 the aircraft received its production designa­tion: MiG-1. The actual assembly of the prototypes began in January 1940, and fewer than a hundred days later, on 30 March, the first machine was moved to the airfield. The first MtG took off on 4 April

In the meantime, in March, Mikoyan was appointed chief con­structor at the no. 1 Aviakhim factory, and Guryevich was named deputy chief constructor. The careers of both men developed along the same lines. On 16 March 1942, by decree of the State Commissariat of Defense, the OKO was reorganized within the no. 155 factory, in Moscow—that is, in the very place where we are talking today. Mikoy­an became manager and then chref constructor of the new OKB. On 20 December 1956 Mikoyan was appointed general designer, a position that he held until 27 May 1969, when he was struck down by a myocar­dial infarction. For his part, Guryevich was appointed chief construc­tor, a position that he retained until he retired in 1964.

Guryevich had by then become no. 2 in the OKB hierarchy. Could you tell us more about his career?

Mikhail Iosrfovich Guryevrch was born in 1892 in Kharkov, a big Ukrainian city. His father worked in a distillery. After finishing high school he entered the advanced mathematics program at Kharkov Uni­versity but was expelled for taking part in a student revolutionary movement. In 1913 he left for France to study math at Montpellier Uni-

versify. After the October Revolution he returned to the USSR and resumed his studies at the technological institute in Kharkov. He orga­nized a group of students there into an aeronautics circle that soon became a formal faculty of aviation, and he left in 1925 with a diploma. After working here and there for four years without finding what he was after, he decided to devote all his energies to aviation (his first love), either in a factory or in a design bureau. He spent time in the OKB managed by P. E. Richard, a French engineer who had been invit­ed by the Soviet government to work in the USSR, and in the one head­ed by S. A. Kocherigin.

In 1937 Mikhail Iosifovich was sent to the United States to negoti­ate a manufacturing license for the Douglas DC-3 airliner. When he returned to the USSR a year later he took an active part in the prepara­tion of the production line for this aircraft (known here as the PS-84 or Li-2) and the development of new manufacturing techniques. Toward the end of 1938 he joined the Polikarpov design bureau to take charge of the study project department. And that is where Mikoyan noticed him. The loop was looped, and the couple who were to many their ini­tials—MiG—was formed.

If we can trust the morphology of their faces, Mikoyan and Guryevich undoubtedly had very different natures. Could you tell us about these two men as individuals?

You are right. They had very different personalities—but often they complemented one another. Mikoyan was as open, outspoken, and convivial as Guryevich was modest, even unassuming. Mikoyan

took good care of himself; for Guryevich, clothes were the least of his worries. Mikoyan had no experience in aircraft construction. He learned on the job. Because of his great knowledge of common manu­facturing problems, he was able to assess a project quickly—and better still, to submit one of his own. Guryevich was erudite, the math expert, the mastermind, who because of his experience and the wide range of his technical knowledge had a talent for drawing up preliminary designs. Without Guryevich, Mikoyan probably would not have suc­ceeded—but the reverse is also true. Guryevich was an engaging per­son, enamored with literature, always shocked by impurity, impolite­ness, and coarseness. He wouldn’t have hurt a fly and was never angry or cross with anyone. He was a married man with no children. Every­one at the design bureau was fond of him, and he proved to be a good social negotiator. Little was heard of him toward the end of his profes­sional life because he was handed responsibility for the “set of themes B,” an innocent name for one of the most secret OKB activities: the development of winged missiles. He retired in 1964 and died of old age in 1976 in Leningrad.

Mikoyan was married and had three children, one son and two daughters. His wife Zoya Ivanovna is still alive. His son, Ovanes Arty­omovich, worked at the OKB as an engineer for a long time; he has a passion for sport aircraft and now belongs to the team of Lozino – Lozinskiy.

Some examples of Mikoyan’s other traits are now coming back to me—I offer them to you in a jumble. For instance, he waited on his pilots hand and foot. He loved to take care of people. When the woman in charge of the workers’ council drew his attention to the poor health of the design bureau’s engineers during the war—at this time we sel­dom got enough to eat—he decided to send us to the country. That is how circumstances led me to make hay, when others organized fishing competitions. We were all able to regain some strength. Mikoyan also liked to fall in with his Armenian friends such as Marshal Bagramian and Tumanyan, Anastas’s brother-in-law. He also struck up friendships with other general designers, including Ilyushin, Tupolev, Yakovlev, and Tumanskiy, an engine specialist who was also a cultured and inter­esting man.

Mikoyan had a cardiac defect, an abnormal thickness of the peri­cardium, that caused a lot of problems toward the end of his life. He was strongly affected by the accidental death in 1968 of Gagarin, who was thirty-six at the time, and by the death in April 1969 of Kadomtsev, the PVO commander-in-chief, a man whom he knew well, in a MiG-25 crash. One month later, on 27 May 1969, Mikoyan suffered a stroke that forced him to retire. On 9 December 1970 he had to be sent to the hospital and died on the operating table.

Mikoyan was a friertd of Tupolev, another famous aircraft manufacturer. They are together here during an air show in July 1949. Right, Zoya Ivanovna, Mikoyan’s wife.

That very day, you were assigned the heavy responsibility of tak­ing over under difficult conditions. I’m sorry to ask, but you must tell us a little about yourself.

[t is always much easier to talk about others, but as you wish to know every detail, I would have you know that Rostislav Apollosovich Belyakov was bom on 4 March 1919 in Murom, in the Vladimir region. My father was a civil servant. After graduating in 1936 I entered the Moscow Aviation Institute (MAI) named after S. Orjonikidze, where I was taught by such prestigious professors as Yuryev and Zhu – ravchenko. I left with a diploma in 1941 and became an engineer at the MiG OKB. My first task was to work on updating the armament of the MiG-3 under the leadership of Volkov, a weapons specialist of great repute. Soon Mikoyan asked me to work with him and put me in

charge of the high-lift devices department. In 1955 I was made director of the research department, in 1957 deputy to the chief constructor, and in 1962 first deputy to the general designer. In 1971, a few weeks after Mikoyan’s death, I was named general designer.

As an engineer and a scientist, what are your favorite activities?

I have devoted much of my time and energies to fluid mechanics, aeroelasticity, problems of strength, flight control modes and conse­quently to flying controls, design of aircraft-plus-missiles systems, power plants, airborne systems, aircraft design, and all advanced aero­nautical technologies. I also pay special attention to materials and sur­vival equipment. As a general designer I coordinate the work of the several design bureaus and research centers involved in the creation of a new prototype.

Could we return briefly to 1971? Tell us how you took over for Mikoyan and how you managed to preserve the spirit of initiative that prevailed in the OKB.

I succeeded in taking over without much trouble. After all, I had grown up within the OKB and had worked in practically every depart­ment. Do not forget that since 1957 I had been working with Mikoyan, in charge of the gears, flying controls, and various other systems and devices, and that since 1962 I had been his first deputy. One day Mikoyan told me, "You will have to decide on everything for yourself.

On 16 March 1942, by government decree, the OKB managed by Mikoyan was reorganized within the no. 155 factory area in Moscow. The area was in fact a wasteland near the Leningrad causeway that held a few crumbling huts, several barracks, an antiquated boiler room, and a small one-story building. It was in the latter that the design bureau set up shop on a primitive level in April 1942 after its return from Kuybyshev, to which it had been evacuated the year before. Quite rapidly, crit­ical restoration and construction projects were completed (1) The site after initial repairs in 1942. (2) The first assembly workshop. (3) Construction of the building planned to accommodate the design bureau. (4) The site in 1943.

So keep calm.” If I had doubts about something, I could always knock at his door. I took part in all important meetings—Mikoyan, who was prone to headaches, abhorred business meetings and frequently sent me in his place, many times at the last minute. Because of my different activities, I was well known in all the departments. As you can see, I was in the best position to take over.

WieZZ then, is aviation the one and only passion in the life of Ros­tislav Apollosovich?

Of course not. When I was a student I loved skiing, especially Alpine skiing and ski jumping. I was a five-time champion in the USSR, once in ski jumping and four times in downhill racing, and I am quite proud of that. With one of my professors, Zhuravchenko, I even ‘’test­ed" a man in a wind tunnel to calculate the best descent attitudes. In 1940 I skied down the eastern side of the Elbrus, which reaches some 5,600 meters (18,600 feet) at its highest point. But I should not forget my wife, Ludmilla Nikolayevna. I met her in Kuybyshev, a port on the Volga River where the OKB withdrew in 1941 at the time of the Ger­man breakthrough. I returned to Moscow with our engineering office staff in 1942, but my wife-to-be did not return until later. We got mar­ried in 1945. She is now retired from her career as a television engineer specializing in large screens. And while I was at MAI I of course learned to fly—either on a Polikarpov Po-2 or a Yakovlev UT-2. I have also made parachute jumps.

You wish to know my shortcomings? I do not know how to relax, how to keep away from my work and think of something else. I like classical music, but I never have time to go to a concert. Besides, I have always regretted not knowing how to play an instrument. I never learned a foreign language either. In my everyday life, I go out for the newspaper and my dog takes me for a walk twice a day. That’s all.
