Being able to get a huge order of 1.7 billion US dollars, and the export products are still high-end industrial equipment, this alone is enough to shut up many people in China.

With the order in place, the funds invested by United Motors Company in Spey-Qingcheng series engines have finally begun to gradually return, and a huge amount of funds have flowed into the account, and the company has begun to carry out equipment upgrades, personnel training, capacity expansion, technology pre-research and other work.

Holding a large amount of money in his hand, at this time, looking at the competition between the domestic 606 and 624 institutes to push the core machine, the two have become white-hot.

The 624 push-core machine has a certain relationship with the F-404 core machine, and the products of the 606 are roughly upgraded from the upper-plane turbojet 14 core machine, both of which are aimed at the three-and-a-half-generation mid-push turbofan market, and the competition is indeed not too fierce.

The military, the Science and Technology Commission, and the Ministry of Aerospace Industry jointly conducted an evaluation, and it was said that the plan of the 606 Institute had the upper hand, and the overall situation was not friendly to the 624 side.

At the same time, the production work of the United Motor Company is still advancing, the 60th turboshaft 6 engine is delivered off the assembly line for the use of the Z-8 helicopter, and the production of Qingcheng engines is also carried out in small batches, and the first batch of 30th engines has been delivered to the 123 factory for assembly in No. 10.

The "Qingcheng Block 5" engine, which is losing weight like crazy, has passed the first stage of testing, and if there is no problem, it is planned that it can be submitted to the military and the expert group for acceptance in 93, so as to put the thrust-to-weight ratio of the Qingcheng engine into the European standard 7 level.

Considering that the "Qingcheng Block 5" is only a small change, it will not have much problem in terms of production, and it is expected that it will be able to start rolling off the assembly line in batches around 94, and when it comes, it will be assembled in batches to the J-10 delivered to combat units in large quantities, becoming a standard third-generation turbofan with mature performance and usability, and there will be no obvious shortcomings.

As for the Qingcheng engine, which is now produced in small batches, although the thrust-to-weight ratio is only 6.5, it can be used for flight training at the Air Force test flight base.

On the other hand, the United Motor Company and Rolls-Royce and BMW have made a push for the civil large bypass ratio, which is deeply improved for the Spey Mk502 engine of that year, the first is to increase the bypass ratio, and secondly, to make a major change to the core engine, using the ternary flow theory to comprehensively optimize the blade shape and modify the combustion chamber.

And so on, and so on.....

According to estimates, this is not so much a major overhaul of the Spey Mk502 as a redesign of an engine, at most only partially retaining the characteristics of the Spey family.

The whole project has been started for more than three or four years, and the research and development work has entered the deep water area, and the project can not tolerate any delay.

"This is an excellent civilian large culvert thrust turbofan, and there is no rival of the same level in the world, so as long as there is a need in this area, there will definitely be aircraft companies to come to us, at most two to three years. ”

The above sentence came from Wang Zhengguo's words after visiting the R&D team in front of all the designers on the scene, and he was very confident in it anyway.

And this is indeed the case, Wang Zhengguo encouraged the team to continue to be full of hope, and then after less than half a year, the domestic production project of McDonnell Douglas 90 series aircraft negotiated between China and the United States finally landed.

In March 1992, AVIC Technology Import & Export Corporation and McDonnell Douglas Aircraft Company of the United States signed an agreement on Sino-US cooperation in the production of mainline aircraft.

With the approval of the state, under the organization and command of AVIC, Shanghai Airlines is the main manufacturer, supplemented by the four major aviation industry enterprises of Xifei, Chengfei and Shenfei, and jointly undertakes the manufacturing and assembly of 70% localization of the aircraft body.

At the same time, the biggest difference from the upper plane also came out.

The upper plane is planned to purchase 40 McDonnell Douglas 90-30 passenger aircraft, this model has a passenger capacity of up to 153, and the engine is also a V-2500-D1 with a thrust of up to 11 tons, and the range is on par with the narrow-body trunk airliners such as 737 and 320.

Essentially, it was extremely unwise to use the fuselage of the McDonnell Douglas 90 series to compete for the narrow-body trunk airliner market, so after the contract was signed, the civil aviation system immediately changed the purchase order from 40 to 20 aircraft within a year.

Now the situation has completely changed, because the United Motor Company and Rolls-Royce BMW jointly developed a new civilian thrust turbofan, the maximum thrust is only 9 tons, so the domestic is also difficult, because the United Motor Company's ability to tackle key problems is too strong.

First of all, United Motive pulled Airbus, Boeing, and promoted the 737 and 320 in various domestic markets.

Directly introduce the narrow-body trunk airliner market to major civil aviation companies, confirm what you really need, what kind of aircraft is the mainstream, and even pull foreign financial companies to provide aircraft leasing services for domestic civil aviation companies, provided that the 737 or 320 series is used in the mainline airliner market.

After various publicity comparisons, domestic civil aviation companies are certainly not fools, and no one can see the huge disadvantages of the McDonnell Douglas series.

This is a threat from the narrow-body mainline airliner market itself, and all of this alone has put orders for the McDonnell Donnell Douglas 90-30 in jeopardy.

Later, United Motors Company threw out a killer idea, stating that as long as the domestic Modu Aircraft Factory changed to produce McDonnell Douglas 90-10 models, the original 9-ton thrust V-2500-D2 engine was replaced, and the RBC-715 engine was jointly developed by United Motors and Rolls-Royce BMW.

Then the benefits will come, Rolls-Royce, BMW, United Motors Company will set up a financial leasing company, purchase at least 60 aircraft of this type, lease them to domestic civil aviation companies for a large number of use, and even invest in the Modu Aircraft Factory to provide strong financial support for the Modu Aircraft Factory.

God, such a good thing fell on the head, how could the Modu Aircraft Factory still hold back the excitement in his heart, the Ministry of Aerospace Industry has revealed more than once that he wants to let go of the Modu Aircraft Factory, after all, this guy has been burning money at a loss until now, and the Ministry of Aerospace Industry can't stand it.

If it weren't for the luck of the magic capital, a super boss was promoted and forcibly asked the domestic aviation industry to renew the life of the magic aircraft factory, which is why the magic capital aircraft factory is barely surviving now.

But this kind of barely surviving, if there is no large amount of capital investment, to achieve the company's development and profitability, hehe?

The forty McDonnell Douglas 90-30 passenger aircraft projects alone were all obtained after the Modu Aircraft Factory begged grandpa to sue grandma.

It can be seen that the Modu Aircraft Factory itself is also living hard, the civil airliner market is different from the military market, it is not the same routine at all, there is no marketization experience, and there is not enough massive capital investment, it is difficult!

Fortunately, now the east is not bright and the west is bright, and "Luo Baolian" suddenly came out, which is simply a miracle, and directly smashed 60 purchase orders, compared to the 40 orders that I got from asking grandpa to tell grandma before, it is not too happy.

As for the subsequent production of the MD90-30 series, or the MD90-10, is there much difference?

They are all McDonnell Douglas 90 series aircraft, and the Modu Aircraft Factory has previously produced the MD-82 series, and the experience is already in place, as long as there is an order, it can be produced here, as for what engine to use, anyway, the V-2500 engine has nothing to do with the Modu Aircraft Factory, if you want to say that it will be changed, it is not a big deal.

With the purchase order of 60 planes on Luo Baolian's side, coupled with a large amount of capital shares, the Modu Aircraft Factory can naturally soar to 90,000 miles.
