Liang Yuan took a general look and found that the people meeting in the small conference room were the chief engineers and chief mechanics of various subsystems of COMAC, all of whom were the core personnel of Yuanjia. Pen ~ fun ~ pavilion www.biquge.info

Since the conference room is the core personnel of the company, Liang Yuan's attitude is also casual, listening to Zhou Yuanhang laughing and ridiculing himself and Ning Wanjia who followed him, Liang Yuan smiled, waved his hand like a great man, and said: "Mr. Zhou's news is obviously wrong. ”

"Behind me is the new intern secretary of the group's logistics department, I just happened to be free today, so I was responsible for bringing the familiar and familiar group environment, and I happened to pass by you to come in and have a look. ”

With Liang Yuan's legendary degree, with the appearance and temperament of the two girls, coupled with the identity of Yuanjia's co-founder and big boss's childhood sweetheart, the twins suddenly became popular in the entire Yuanjia management system after the Yuanjia conference, and their popularity and recognition were far higher than Liang Yuan's genuine corporate founder.

Countless reliable and unreliable gossip is flying all over the sky, from the old story of the big boss being "****" in his childhood to the triangular love affair that began in kindergarten, and the rumors that the three of them bombarded the wall of Nanhu Science and Technology Park a year ago have spread even more.

Now everyone in the room watched the big boss thin donkey pooping and pretending to be an elephant there, and many people couldn't help laughing.

"You go on, you don't have to start from scratch, I'm just here to sit in and don't say anything. ”

Liang Yuan said as he searched for an empty seat.

However, Ning Wanjia gave Liang Yuan a lot of face, and did not speak, so she nodded to everyone in the room like a little daughter-in-law.

After Liang Yuan found a place to sit down at the conference table, Ning Wanjia, like a professional secretary, held a pen in one hand and a big notepad in the other, pulled a chair and sat behind Liang Yuan, with a bit of professionalism in the workplace.

Zhou Yuanhang and Liang Yuan have been together for a long time, and they also know that Liang Yuan has a peaceful temperament and has no arrogance, so he knocked on the table, pulled everyone's attention back, and continued the topic just now.

"Let's start with a quick wrap-up. Zhou Yuanhang used the end of the marker pen to tap a series of English letters on the whiteboard.

"If there are no surprises, the CM100 airliner's powertrain should be sourced from these suppliers. ”

On the writing board, GM CF34-8C series, Rolls-Royce and BMW BR700 series, Snecma and GM joint venture CFM56-7 series, International Aero Engine Corporation V3000 series, Allison GMA3007 series, Snixon M123 series, Pratt & Whitney JT8D2000 series, a total of seven series of aero engine main performance parameters are listed densely.

No matter how many people in the European aviation community are optimistic about the CM series regional airliner project, they have to admit that the power selection of the CM series regional airliner has become the most eye-catching hot spot in the international aviation industry recently.

After all, it has the endorsement of the republic known as the world's largest market, and in the long-term view of 20 years, this is likely to represent the market share of tens of thousands of aero engines.

In the international aviation power industry, the companies that have the ability to compete for the power supplier of the CM series passenger aircraft are all absent, and the competition between Sneckner of France and General Motors of the United States is almost bayonet, and the two companies jointly launched the CFM-7 series of bidding, and each of them separately bid for its CF34-8 series and M123 series.

"From the point of view of technical parameters, the main performance of the products of the seven suppliers are in line with the power requirements of the CM100 and CM200 models, but considering that CMB Aerospace will definitely launch the CM300 or even CM400 series with more passengers in the future, then the IAE-V3000 and Allison GMA3007 with weak technical research and development strength will be our final installation selection target. ”

"Do you have any objections to this?"

Zhou Yuanhang drew two crosses with a water-based pen behind the names of International Aero Engine Company and Allison Company.

After twenty seconds of silence, Zhou Yuanhang saw that no one spoke, and nodded with a pen on the name of the CFM56-7 jointly produced by Snekma and GM, and continued: "Among the remaining five power options, CFM56 is a relatively special existence, and everyone knows that the number CM400 is definitely not the end of COMAC's future planning. ”

"If you think about it from a future perspective, the CFM56 series, which has been used on a large scale on the Boeing 737 family for many years, will be the best choice for CMB Aerospace Power's partners, but for the CM100 and CM200 series products, which are currently the main products of the group, the overperformance of the CFM series engines is too obvious. ”

"Even though the CFM joint venture promises that the thrust starting model in CFM's latest 7 series products will be lowered to about 67,000 N, which fully meets the power needs of the CM100 passenger aircraft, the price of CFM products is still too high compared to other competitors. ”

Zhou Yuanhang also drew a cross behind the CFM name.

"Two minutes of free discussion, and other ideas were put forward in a timely manner. ”

"Xiaoyuan, CFM will be eliminated?"

Seeing that many people in the conference room were exchanging words from ear to ear, Ning Wanjia stabbed Liang Yuan and asked with some surprise.

With the successful dominance of the Boeing 737 series passenger aircraft in the global short- and medium-range civil aviation market, the CFM56 series engine bundled with the 737 passenger aircraft has also become the king in the power field of narrow-body trunk passenger aircraft.

In the past few years, Ning Wanjia has learned a lot of business knowledge from Liang Yuan when operating in related fields, and naturally knows the benefits of choosing a mature and reliable system sub-supplier that has proven itself in the aviation field.

Considering Liang Yuan's ambition for the mainline airliner market and his temperament of not being bad for money, Ning Wanjia has always thought that the CFM series engine will be a strong contender for this power selection, and he thinks that CFM will be eliminated almost in the first round.

"The price of CFM is too expensive, and the purchase cost of each passenger aircraft is at least one million dollars higher than that of other brands, and the cost has outweighed the benefits from logistics and safety. Liang Yuan whispered.

No matter how the CFM series engine is designed to yield to the CM regional airliner project, it cannot change the fact that its basic structure is mainline power, so some costs cannot be saved anyway, otherwise the CFM engine will not become an excellent mainline airliner power.

Hearing Liang Yuan say this, Ning Wanjia nodded in understanding. (To be continued.) )
