When it comes to MIG-15, we can't help but mention what the Soviet Union got from British Rolls-Royce. Nin？ The legendary story of the engine. In the European battlefield of World War II, the allied forces led by the United States launched a strategic bombing on the inland of the Axis countries led by Germany.
Facing the overwhelming allied air strikes and tens of thousands of long-range bombers and escort fighters, the German army developed the first fighter Me262 that can be used in actual combat in human history. This fighter is equipped with two centrifugal jet engines and four powerful guns with a diameter of 30 mm, which are specially used to attack bombers using high-speed surprise tactics. It can tear up the American B- 17 as easily as an adult tears a chicken leg. Air fortress? Or the Lancaster strategic bomber of the British Air Force. In the case of absolute quantity disadvantage, the ventilation ratio between Me262 and allied aircraft is about one to five.
After the end of World War II, the victorious countries realized the great advantages of jet fighters and their potential in future wars. Both the United States and the Soviet Union snatched the technical data of German Me262 and the remaining prototype parts, and quickly developed their own jet fighters. Air forces of various countries began to enter the jet age. The Soviet Union first copied the German Junk Jumo 004 and BMW 003 jet engines, then independently developed the first domestic jet engine TP- 1, and then developed the RD- 10A/20 turbojet engine. However, because the aviation technology foundation of the Soviet Union was behind the West at that time, it was found that the engine designed and produced by the Soviet Union was of low level and extremely low reliability.
Jacques-15 and Jacques-17 were the first jet fighters produced in the Soviet Union. As a result, their performance is even worse than that of propeller fighters with piston engines at the end of World War II. Even the better MIG -9 jet fighter introduced later, its performance is not satisfactory. For example, in the early 1950s, the China Air Force successively received all aviation equipment from the Soviet Air Force 13 Aviation Division.
These include 358 MIG -9 fighters. Because the engine thrust is too small, MIG -9 has poor maneuverability and insufficient reliability, and accidents continue. According to the battlefield assessment of China Air Force, MIG -9 can't even beat the American F-80 fighter-bomber. The Soviet Union actually admitted the accusation.
195 1 In May, the Soviet Union called China twice to apologize and pointed out that due to the Soviet side's misjudgment of the combat effectiveness of MIG -9 fighters, the Soviet Union would provide China with 372 latest MIG-15 fighters from six fighter divisions for free to replace all six MIG -9 fighter divisions of China Air Force, and all MIG -9 fighters were retired from China Air Force. This shows that the backward engine has seriously caused a drag on the construction of the air force.
Recognizing its own shortcomings, the Soviet Union began to introduce reliable high-thrust jet engines. The Soviet Union turned its attention to Britain, because the Nin and Deventer V jet engines of British Rolls-Royce are advanced, with large thrust, light weight and stable operation, which can best meet the needs of the Soviet Air Force. There are two ways for Soviet intelligence agencies to suggest, either directly buying or secretly stealing.
Jakovleff, a master of aircraft design, also suggested to Starling: Doesn't Rolls-Royce in Britain have a particularly advanced Nyan engine? We just bought it back! As a result, I was angry with myna: Selling advanced engines to your enemies? What fool in the world would do such a stupid thing? ? Starling himself has serious doubts about buying British engines: only idiots are willing to sell us their top secret technology! ? However, on earth, there are really idiots! ?
This is an Englishman. It is a tradition for the British to communicate with the Soviet Union. The precedent is Britain's actions during the war. 1In the summer of 944, for the purpose of wooing allies, Britain presented the Soviet Union with a captured Nazi German V-/kloc-0 missile wreck and a pulse jet engine (with Churchill's extreme anti-* * anti-Soviet thoughts, probably by the nose).
This is the TR- 1 turbojet engine developed by the Soviet Engine Design Bureau in 1946, based on the design of axial-flow engine seized from Germany.
So the Soviets began to try to get in touch with the British. When the Soviet Union offered to buy advanced engines with a try mentality, the British were worried about the post-war reconstruction funds. Wrong country? The prestigious British Labor government readily agreed to the purchase request of the Soviets. 1946 in may, the Soviet trade office in London contacted rolls royce company to inquire about the purchase of jet engines and the production license. The answer is encouraging: Britain can directly sell derwent and Nyn centrifugal jet engines to the Soviet side, as long as it pays.
The Soviet Union immediately proposed to buy 10 derwent and 10 annual ring centrifugal jet engines, and promised to buy hundreds or even thousands of annual ring engines in the future. The Englishman who is crazy about money sent it at once. In this way, the Soviet Union got 55 sets of valuable products in two batches. Nin？ Engine: 1947, kerimov engine design bureau first produced the RD-45 engine, and then developed the VK- 1 engine on this basis, and the engine thrust was obviously improved. Created the first generation MIG-15 jet fighter that red empire can really get.
The British are still waiting for the Soviets to continue to buy engines or patents in large quantities. As a result, there will be no more, and the Soviets will never come back. After these derwent and Nien engines arrived in the Soviet Union, they were immediately sent to professional factories for reverse engineering and cottage, and were immediately studied by the Soviet aviation industry. It wasn't long before the Soviet Union produced an imitation engine. Soviet shanzhai version? The annual ring RD-45 centrifugal jet engine was born rapidly, and MGM got the RD-45 even more powerful. The MiG-15 fighter plane appeared in 1948, which proved the short-sightedness of the British, and its later combat performance over China and the peninsula fully proved this point.
1946, the Soviet Union paid 360,000 pounds in cash to buy 55 British engines, which was a very cost-effective transaction. 1In the late 1950s, Whitney, Vice President of Rolls-Royce Company in Britain? Twitter visited China and found a fake made in the Soviet Union? Nin？ And then what? Derwent? Engine, so the British got angry and sued the Soviet government, accusing the Soviet Union of despicable acts of infringing British intellectual property rights and claiming 200 million pounds. Of course, the Soviet government didn't even respond politely, and the matter went away.
