"Mr. Lin, do you really plan to use our computer as the core of aircraft avionics?" Fang Xinzhu was a little hesitant.

Although Lin Hongfei's decision is what Fang Xinzhu wants to see the most, it has been eight or nine years since he received Lin Hongfei's capital injection and the task of jointly developing an airborne computer system with the Northwest Computer Research Institute.

After three years of testing, it has been determined that the safety and stability of this system have met the requirements of commercial use, and the avionics system built with this airborne computer system as the core has also been developed, and it has been simulated by a super-large computer, which can fully meet the requirements of normal use.

Whether it is the Northwest Computer Research Institute or the Inspur Group, they are very satisfied with this achievement, nearly 10 billion funds have been thrown into it in eight or nine years, if there is no result, even they feel that it is difficult to explain, but when they think that this system is about to be delivered, Fang Xinzhu can't help but feel a little apprehensive, he is a little worried, if something goes wrong, how should this be?

"Of course we have to use it, isn't it just that one day the avionics system of our own aircraft can get rid of the control of the Americans?" Lin Hongfei glanced at Fang Xinzhu, not understanding what he was hesitating about, "What?" Lao Fang, what are you worried about? Or are you not confident in the system? ”

"Of course I'm confident!" Fang Xinzhu straightened his chest and said without hesitation.

This set of on-board computer system has cost Inspur Group and other Hsinchu countless efforts, and the Northwest Computer Research Institute has built a large aircraft avionics system with optical fiber as the core of this system. Collins has a similar product that is poor. The same multiple large LCD screen displays, the same high degree of automation, but the price is only Rockwell. Less than a quarter of Collins' similar products, if this system is used, the cost of the North County 100 and North County 200A/B series aircraft can be reduced by two or three million US dollars, which not only further enhances their competitiveness, but also does not have to worry about being stuck by others, and at the same time promotes the development of domestic avionics technology.

"But...... After all, the time for testing is still short. Shall we take another look? Fang Xinzhu was still a little worried.

"There's no need to wait, it's good," Lin Hongfei made up his mind directly, "Even if it's the worst case, isn't there a backup system?" That's it...... It's a helicopter-specific avionics system. You need to hurry up. ”

Fang Xinzhu naturally knows what the helicopter-specific avionics system that Lin Hongfei said is, and the Republic does not have its own highly automated helicopter-specific avionics system. The avionics system of the Z-9 is an asset though. But it was bought directly from the French, although the follow-up also carried out some development on this system, but if you say self-development, it is still a lot worse, compared with the Z-9, the Z-9Y, a unique helicopter in the world, needs to develop a new automatic avionics system, according to Mr. Guo. Although the avionics system on the Z-9Y can also be used, it is a pity that this system cannot give full play to the full combat strength of the Z-9Y.

Lin Hongfei said so, what else can Fang Xinzhu say? Mr. Lin gave himself such a great trust. The only thing I can do is to do my best to test out the bugs of this system, otherwise something will really happen in the future, and I will not be sorry for Mr. Lin's trust at all.

With the price of fuel this year to climb at a rocket-like speed, the soaring fuel prices have made the major airlines complain, just the expenditure on fuel, has increased from 15% of the total operating costs in 2000 to 20% at the beginning of this year, according to the predictions of the major think tanks, by 2008, aviation fuel will account for 35% to 40% of the total cost of airlines, this forecast came out, the major airlines suddenly could not sit still: and rolls-Royce, General Electric and Pratt. Compared with Whitney's aero engines, AVIC No. 2 engines really don't have an advantage in terms of fuel economy.

"Mr. Lin, don't get me wrong, we have absolutely no other meaning, your company has provided us with high-quality and low-cost products, which not only greatly saves the procurement costs of our major airlines, but also greatly reduces the expenditure on aircraft maintenance, even if the fuel consumption of BD1000 engine is about 30% higher than that of CFM56-5B series and V2500 series, but for now, if you measure comprehensively, in fact, you still have an advantage, this time please Mr. Lin to come over, just want to discuss, There is no fit, at least expected, solution. Huang Suning, general manager of AVIC, looked at Lin Hongfei with an extremely sincere expression.

Lin Hongfei can't be easily offended, and AVIC No. 2 Group can't be easily offended, the issue of aircraft procurement has always been part of the country's grand strategy, not airlines can buy whatever aircraft they want, everything must be based on national interests.

"I fully understand," Lin Hongfei nodded, "To be honest, the fuel consumption of the BD1000 engine is indeed a little high, and I don't hide it from all of you here, in our second AVIC group, we have always regarded BD1000 as a transitional product, and then we will promote BD1000-B, for this engine, I believe that all the leaders here are clear, although in terms of fuel economy can not be comparable with CFM56-5B series, V2500 series, However, fuel consumption can be reduced from about 30% higher to about 10%. ”

As soon as Lin Hongfei said this, everyone let out a long breath!

They are really worried that Lin Hongfei has any misunderstanding about this meeting, Lin Hongfei and his AVIC Second Group now have a pivotal position in the minds of the big leaders, if Lin Hongfei thinks that he and others are "forcing the palace" and reporting to the big leaders, he really can't eat and go around.

Ding Hao, general manager of China Southern Airlines, his eyes lit up, and he hurriedly asked Lin Hongfei, "What does Mr. Lin mean...... Free replacement for more fuel-efficient BD1000-B? ”

"Free replacement?" Lin Hongfei looked at Ding Hao with a smile, "Mr. Ding, it doesn't seem to be what we said in the contract we signed at the beginning, right?" If I'm not mistaken, should the BD1000 engine be upgraded to a more advanced model at cost price? ”

"Huh...... Is that the case? That's what I misremembered. Ding Hao smiled wryly, of course everyone didn't expect to be able to replace the engine for free, but if Lin Hongfei was willing to replace the engine for everyone for free, of course he would not refuse.

"But there is a problem here, the maximum thrust of BD1000-B is 150 kN, such a large thrust, is there some excess thrust for our airline?" Lin Hongfei reminded him euphemistically.

Well? Hearing Lin Hongfei say this, the heads of major airlines couldn't help frowning: Lin Hongfei is right, in their opinion, BD1000's 126.8 kN thrust is just right, BD1000-B maximum 150 kN thrust is indeed some excess thrust, thrust is large, the fuel consumption needs to increase accordingly, this is the truth that is bumpy and unbreakable, even if BD1000-B is larger than BD1000 greatly enlarged bypass ratio, but also need to increase the fuel supply accordingly, In terms of unit fuel consumption, in fact, BD1000-B is actually slightly higher than BD1000 fuel consumption.

"I don't think it's a big deal," said Wang Gang, general manager of China Eastern Airlines, "I think the thrust of the BD1000-B is just right." ”

"What do you mean by that?" As soon as Wang Gang said this, not only Lin Hongfei was curious, but also the eyes of the heads and brains of several other major airlines also converged on Wang Gang.

"It's very simple, cargo, because the thrust of the engine is not very large, in fact, we can't play the maximum cargo capacity of the North County 200, theoretically, the maximum cargo capacity of the passenger North County 200 can reach 50 tons, but because of the engine thrust, the maximum cargo capacity of the North County 200 can only reach 15 tons, if the engine thrust is increased by almost 50 kN, how much cargo can be increased? At least 15 tons is not a big problem, right? ”

"Of course, even if the cargo capacity can be increased to 30 tons under the premise of ensuring passenger traffic, it also needs air cargo support, I am not very clear about the situation of other brother units, but we are preparing to launch a batch of cargo aircraft, if we can increase the maximum cargo capacity of the aircraft to 30 tons by replacing the engine, with the number of our Eastern Airlines' existing North County 200, we can completely postpone the procurement of cargo aircraft to 3 years later, which is equivalent to saving us at least 3 cargo aircraft procurement costs, From this point of view, I personally think that it is a good idea to replace the engine with high thrust. ”

Well? As soon as Wang Gang said this, everyone pondered.

We have to admit that Wang Gang's words are very reasonable, with the development of the economy, more and more people travel by plane at the same time, there are more and more goods by air, not only China Eastern Airlines, but also the airline where they are located, on the one hand, there is a surplus of passenger capacity, on the other hand, there is a shortage of cargo capacity, if you can improve the freight capacity by replacing the engine, it is indeed a good way to save money and worry.
