Seeing that the genuine proprietress sitting behind Liang Yuan was still a little confused, Zhou Yuanhang briefly added some things about Pratt & Whitney. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

"The earliest Boeing 737-100, 737-200 passenger aircraft are used Pratt & Whitney engine, that era of Pratt & Whitney JT8D series in full swing, once occupied more than eighty percent of the aero engine market, but unfortunately a good hand in just a few years was completely ruined by Pratt & Whitney, from 737-300 Pratt & Whitney engine was completely abandoned by Boeing. ”

"The American aviation community once satirized Boeing, saying that the only thing Boeing learned from its cooperation with Pratt & Whitney was arrogance, arrogance, lack of progress, disregard for customer needs, and then grew into the largest bureaucracy in the United States. ”

"For example, if you choose Pratt & Whitney engine, after installation, you find that some aspects do not match expectations, for us who have little influence on the industry, Pratt & Whitney is very likely not only not to take responsibility, but also to accuse us of some of the data we provide is wrong, after all, the engine is installed on the aircraft, the two must affect each other, and then whether it is a lawsuit or a lawsuit can be dragged to death. ”

In order to obtain the relevant basic authorization of chips from MIPS, Liang Yuan bluffed and set up a lawyer team of nearly 100 people, which gave MIPS great financial pressure, and then forced MIPS and Gangji to sign a settlement agreement similar to a technical VAM.

Compared with the experience of Hong Kong-based power collector, Ning Wanjia showed a look of sudden realization.

In just ten minutes, four of the seven international aviation power suppliers have been eliminated, and now only GM's CF34-8C series, Rolls-Royce's BR700 series, and Snecma's M123 series are left on the board.

GM CF-8C series and Rolls-Royce and BMW cooperation BR700 series is the remaining three of the strongest two, although Rolls-Royce and GM compared with the most representative of the aero engine research and development strength of the military push product line is temporarily blank, but at this time Rolls-Royce is not without the strength of research and development of military push, but the British military has no demand.

At present, the top achievement in Rolls-Royce's civilian product line, Ruida 600, has completed its first operation, waiting for the installation of practical use, but unfortunately, the starting user of Ruida 600 is officially the current stormy McDonnell Douglas company, MD11 in Europe can be called dismal sales performance makes Ruida 600 is still in the state of demonstration prototype.

When it comes to the selection of engines for the CM100, Rolls-Royce has great confidence.

Although Yuanjia's name is not obvious in the world, Rolls-Royce, who has cooperated with Brilliance Power for a long time, naturally knows that COMAC, the major shareholder of CMB Aerospace, is a subsidiary of a large consortium in the Republic of China, which is a very important benefit for Rolls-Royce.

Another reason to support Rolls-Royce's self-confidence is that the BR700 series engines have a certain German background due to BMW's investment, and MBB, another major shareholder of CMB Aerospace, has a certain preference for BR700 engines due to the influence of the German government.

As for GM's CF34-8C series, GE's leading position in the aviation power industry and the world's largest supplier of turbine power systems is enough to determine the competitiveness of GM's products is the strongest among all bidders.

Since CM100 is the world's leading new generation of regional airliner power system procurement, there is no real engine can be used as a reference at this time, all product data are the expected goals planned by the supplier on paper, therefore, the supplier's technical research and development strength has become an important factor in whether to choose cooperation.

If it weren't for Liang Yuan's command of COMAC to set up obstacles for the selection of the power system, GM would have won the procurement bid for the engine system of the CM100 passenger aircraft with its product strength.

Strictly speaking, the technical level of the remaining three major power suppliers, the technical level of France Snecma is relatively weak, and in the long-term evaluation made by COMAC, the technical capabilities of France Snecma can support the CM300 model.

In the long-term planning made by COMAC, as long as the purchase quantity of CM100 and CM200 passenger aircraft reaches the break-even point, in addition to the new modification with a small technical update, the CM300 model with a larger number of passengers will also be officially approved.

According to the technical expectations on the current drawings, the maximum number of passengers carried by CM300 is 160 when adopting a high-density seat layout, which is close to the Boeing 737-400 series, which puts forward higher requirements for the power system of passenger aircraft, and the thrust of a single aero engine must reach at least 90 kN or more.

As for the 120 kN aero engine required for the later CM400 model, it is already a standard large-duct medium-thrust turbofan engine, and in addition to the three major international aviation power providers of GE, Pratt & Whitney and Rolls-Royce, there is no power manufacturer on the planet that can rely on its own research and development capabilities to independently squeeze into this threshold.

The reason why Snecma is still at the top of the list of the best cooperation with COMAC is mainly because Snecma has shown the greatest sincerity among the seven power suppliers.

Strictly speaking, the capital and technical potential for the development of an advanced large-duct medium-thrust turbofan engine are not lacking in France, the problem is that after a large amount of money is smashed, the product comes out, where is the market?

The three industry leaders of GE, Pratt & Whitney and Rolls-Royce are unlikely to relax the intensity of competition in the market, and watch a big tree on the Snecma list slowly push a large culvert to gradually improve and mature.

As a lagging industry catch-up, what Snecma needs most at this time is the republic's unique executive order, ignoring market risks and bundling the development and sales of a potentially best-selling aircraft, which will benefit greatly once this policy is successful and may even establish Snecma's position as the fourth largest in the international aviation power industry.

It is a pity that free France cannot have an executive order similar to the republic, although France has a huge influence on Airbus, and the engine thrust required by Airbus's models is at least 100 kN, and Snecma, who has not undergone low-level large ducted turbofan training, suddenly develops power at this level is tantamount to suicide.

"The French industrial system is maverick in the world, in the main areas of modern industry have basically maintained a high level of competitiveness, as we all know, the aero engine industry is known as the flower of industry is also the top crown of the aviation industry, NASA has done research, every dollar invested in the aviation industry, eight to ten years later, from its related industry chain will get at least twelve dollars in return. ”

Zhou Yuanhang said as he drew a circle on Snecma's name.

"For countries with developed basic industries, the return on investment in the aviation sector is extremely rich, which is why the Federal Republic of Germany has invested heavily in regional airliners, and for the same reason, the French government and companies have been trying to find opportunities to improve the competitiveness of the French aviation industry. ”

"Although the establishment of CMB Aerospace does not threaten the French-led Airbus for the time being, it is a great obstacle to France's ambition to integrate the European aviation industry, which is the main reason why the French media has been singing about the CM regional airliner project. ”

"However, with the advancement of the project, the situation has changed again, although CMB Aerospace has increased the difficulty of France's integration of the European aviation industry, but also brought new opportunities to the French aviation power industry, as I said earlier, once CMB Aerospace's judgment on the development trend of the regional airliner industry has become a reality, then it is a once-in-a-lifetime development opportunity for France Snecma. ”

Strictly speaking, the French saw this opportunity as an inspiration. ”

Zhou Yuanhang casually slapped someone's ass.

Marcel Gomez, technical director of the Snecma R&D center in France, formally put forward a proposal at an exchange meeting on the power selection of the CM100 passenger aircraft three days ago, which is to imitate the cooperation between COMAC and MBB to jointly develop a large-duct medium-thrust turbofan engine based on the core combustion chamber of the M88 engine. ”

Marcel Gomez briefly introduced the framework of the plan, the whole plan is roughly invested 1.6 billion US dollars, by the two partners to bear the share of the development work in principle 50% of the share of the development work, Snecma will transfer the advanced technology for the production of the M88 engine to the partner at the partner price, but does not involve the production data of the M88 engine, the specific details if we are interested in further consultation. ”

"The core meaning of the French is that we contribute money and market, and the French contribute advanced production technology and equipment to cooperate in the development of a new mid-push engine on the basis of M88, I think the proposal of the French has an important role in the layout of the group's aviation industry, and has greatly promoted the development of Brilliance Power, and the idea of Snecma is a topic worthy of in-depth discussion. ”

Speaking of this, Zhou Yuanhang's gaze moved to Liang Yuan, made a gesture to count money, and said with a smile: "Now it's up to Da Shao." ”

Zhou Yuanhang, who has entered the core layer of Yuanjia, naturally knows Liang Yuan's plan for Brilliance Power, and the reason why Li Yuanling has not officially started the imitation of Rolls-Royce's "Thai" turbofan engine is that he is waiting for the metal laboratory led by Zhu Liguo to thoroughly digest the heat-resistant alloy technology from Spey, and the other is to wait for the supercomputer that the wave will take off the assembly line.

Although the French are inferior to Britain and the United States in the design of aero engines, and inferior to Japan in heat-resistant materials, the French also have unique features in the weight reduction, bearing, and structure of aero engines, such as the application of polyimide resin in the engine casing, such as brush seals, etc. (To be continued.) )
