When entering the formal cooperation negotiations, Su Ming figured out that the original people did not come for the cooperation of domestic independent new fighters, but for another project, and the 611 Institute also had a cooperative fighter project with Pakistan, which was the original Jian-7 transformation project.

The original project called Sabre, now called Super Seven, because of the impact of the previous turmoil, the original partners have withdrawn, the original engine can choose GM's F404, Pratt & Whitney's PW1120 and Rolls-Royce's RB199, now an engine can not be found, and the project has stalled.

However, neither of the two sides is willing to let this project die, especially Pakistan, due to the blockade, the United States originally provided the F-16 can not be obtained, and it is fully expected that this fighter will resist the threat of India, so Pakistan re-contacted the Italian side to provide avionics equipment, and the engine problem was handed over to the Chinese side, and the 611 Institute used most of its strength in the development of new tactical aircraft, while looking for engine partners for the Super Seven project, which was not enough. At this time, the Russian Mikoyan Design Bureau suddenly came to the door, hoping to adopt their RD-33 engine.

Michael Young Design Bureau is the manufacturer of MiG series aircraft, China's J-5 to J-7 are imitations of their MiG series aircraft, even J-8 also has their shadow, but now, after the collapse of the Soviet Union, the national strength is weakened, he and Suiho are becoming more and more difficult, but Suiho won the contract in China, but his life can not be found, at this time, the 611 super-seven project into their sight.

Although it was a small project, it was better than nothing than nothing and waiting for the technicians and skilled workers to quit, so he took the initiative to join in and offer to participate in the project and provide technical assistance for the project.

The 611 Institute naturally will not refuse, he has a long and good relationship with the Michael Young Design Bureau, and most of his energy is focused on the new aircraft, but the Pakistani side is worried, because the original aerodynamic layout can not use the RD-33 engine, changing the engine means that everything has to start all over again, and the main funding for this project is the Pakistani side, which will increase the investment naturally through him.

The Mikoyan Design Bureau is unwilling to give up this business, isn't it to change the aerodynamic layout, it's a very simple thing, the J-7 was originally their MiG-21, although it has been modified by the original American company, but in their opinion, there is still a lot of room for improvement, and a new improvement plan was proposed, this one change continues, the super seven and the original J-7 can no longer find a little relationship in the appearance, and it is more in line with aerodynamics, close to the new third-generation aircraft standards, the Pakistani side has considered and verified, decided to increase investment, Move the project forward.

Because this project was designed from the beginning of the consideration of export sales, although Pakistan is for its own use, it also wants to earn back the research costs of the fighter through export sales, because he has many Islamic buddies, so he asked the Mikoyan Design Bureau to transfer all the technical patents, and not to set restrictions for export sales, but the engine designer Klimov Design Bureau did not agree to this condition, because his engine was originally mainly exported, and he was afraid that once all of it was transferred, it would affect his business.

The super seven project stopped again, among the three parties, the Chinese side is the coordinator, they should come forward to coordinate with both sides, but he himself has encountered engine problems in the new fighter, because the prototype of this new fighter is based on the Israeli "Lion" fighter redesign, the original design of the Lion fighter is to use Pratt & Whitney's PW1120 engine scheme, and the Chinese side simply can't find an engine with similar thrust, that is, the RD-33 can not meet the requirements.

But the engine is the top priority of a fighter, which determines the overall surname of the fighter, this is not a matter of improvisation, the domestic 601 Institute is the most technical in terms of engine, but their main focus is on improving the turbojet engine supporting the J-8, and they are not enthusiastic about the more difficult turbofan engine.

611 Institute thought of mastering the Spey MK202 engine technology of the 603 Institute, although the thrust and thrust-to-weight ratio of this engine is not up to the requirements, but we can improve it, 611 Institute is also a bit like pwww.xstxt.orgk202 to improve, not to mention, first improve to super seven can be used, and then continue to improve, step by step.

The 603 Institute does not have this patience, he studies bombers and transport aircraft, and the requirements for the thrust-to-weight ratio and afterburner of the engine are not high, and the requirements of the 611 Institute are just agreed to provide all the technical drawings and means of production, which means that you can change it as you want, don't bother me.

The 611 Institute is not good at engine research, and there is no special research institute, and it is useless to get the information, and it is worrying there, it just so happens that Su Shi sent a cooperation intention, although I have not heard of the name of this company, but the dead horse is regarded as a live horse doctor, and they can't take care of it so much.

Of course, before they came, they also inquired, knowing that this is a Hong Kong-funded enterprise, and it seems to be good at mechanical processing and the production of special materials, although it cannot be said that it is not related to the engine, but considering that there is little hope, the important people who were going to come temporarily found an excuse and reassigned a few ordinary personnel.

After arriving here, when they saw Su's machine tool production line, they also recognized Su's processing ability, but for research capabilities, they saw that Su's had several foreign consultants in the field of engines, and they thought that Su's research institutions were abroad, and they didn't doubt it much, especially when Su Ming took out a turbine disc to prove his ability, they believed it even more.

The turbine disc is a vital component in the turbofan engine, to be able to produce this kind of thing, and the others are not a problem, at least with Su's ability, it should not be a problem to produce the original Spey engine, as for improvement, it depends on Su's research and development capabilities, but the plane is not a toy, the research period is often ten or twenty years, in the short term, they have no idea, there is always one more choice is not.

The 611 Institute soon sent another team, in addition to signing a formal cooperation agreement, and shipped a full set of Spey MK202 technical data and drawings, and at the same time allocated $200,000 from Pakistan as an upfront cost, and at the same time required Su Shi to come up with an improvement plan after three months.

This problem is not so simple, you want to improve you must be completely thorough in technology, a full set of information with almost two wagons sent over, you can imagine how much, three months even to see it has not been read once, that to improve the program, this is not embarrassing.

Without waiting for Su Shi to object, the other party grabbed him again and whispered in his ear to tell him that in fact, he just needed to get a data table, and said that he was going to increase the thrust from how much to how much, how high the combustion temperature was raised, and how much fuel consumption could be reduced.

Is this what is going on, Su Ming waited for them to leave and then got a large engineering drawing scanner, and then got all the drawings into the computer, after it was completed, Su Ming began to worry about the computer, this game is not a thing that people can understand at all, after watching it for a long time, except for the dizziness of the person who watched it, he didn't understand anything.

I can't figure out what these principles and structures are, Su Ming found the manufacturing materials of the engine, this can be understood, the alloy alone needs nickel-based alloys, nickel-cobalt alloys, titanium alloys, high-temperature powder alloys, a total of seventeen different metal composite materials, and this multi-material, Su can produce only five or six kinds, but fortunately, the remaining ones can be purchased in China.

Why don't you make one out first and try to see if it can be started, let's observe how the engine of the aircraft works, Su Ming thought of it, and immediately asked people to purchase raw materials, and at the same time began to trial produce various components, with enough processing capacity, it only took more than 20 days to process a finished product.

But what is disappointing is that even the ignition could not be successful, Su Ming checked it according to the drawings and found no problems, as for the analysis, Su Ming did not have this ability, so he could only look at it depressed, obviously all the parts were checked again, and they were all produced according to the drawings, why didn't it work, could it be that there was a problem in the assembly process?

Su Ming checked again, and then tried again, but the result was still a failure, tried for several days in a row, but did not solve this problem, Su Ming even suspected that the drawings were on the drawings, and checked again according to the original drawings, and still did not find anything, asked 603, 603 said that what was given was the original drawings, and the British side gave two sets at that time, and what you took away was the one we used, and the drawings would never be a problem.

Su Ming's head hurt when he thought about it, and there was no way, this thing was really not a simple play, even if you had drawings, you couldn't play with it, but if it was so easy, it wouldn't be worth millions of dollars, what should I do now? Isn't that the end of it?

But the agreement has also been signed, the money has been taken, and he has decided to prepare to develop in this direction, just forget it, how to do it, he has not failed so much, Su Ming frowned, relying on this guy who seems to have a high technology content but is actually a pile of scrap iron, he doesn't know how to do it.

"Can I help you?" A timid voice suddenly sounded in my head.
