"Feasible!" Facing the old general's eager gaze, Lin Hongfei gave an affirmative answer!

"It's feasible!" The old general slapped his thigh hard, "This project is the confidential project that your unit will do next, and someone will contact you later......"

"Chief, there are some situations that I must explain first," Seeing that the old general's order was about to come down, Lin Hongfei couldn't care so much, and interrupted the old general's words without caring about the rules, "Now the Beijun 400 has just started the test flight, even if everything goes well, it will take at least 7 to 8 years of test flights to determine the safety of the aircraft, that is to say, it will take at least 10 years for this project to be operational." ”

"Well, you go ahead." The old general groaned for a moment and nodded.

Although Lin Hongfei said that the time span is relatively long, the old general also admitted that what Lin Hongfei said is indeed reasonable, this kind of aircraft that retains the most remedial counterattack ability for the country at the end of the world, safety must be put first, Beijun 400 as a brand new aircraft, if you want to have the conditions to be converted into a doomsday aircraft, it will take at least 10 years later, this kid is not exaggerating.

"Although the size of the Northshire 400 barely meets the requirements, I personally think that this aircraft is still a bit small as a prototype of the Doomsday Aircraft, and you know that Airbus is developing a larger aircraft than the Boeing 747: the Airbus A380, which is expected to be able to fly next year, and I personally think that an aircraft of this class like the Airbus A380 is more suitable for conversion to a doomsday aircraft."

The old general glanced at Lin Hongfei thoughtfully, with a smile in his eyes, "Good boy, do you want the country to support your Beijun 800 plan?" ”

The Beijun 800 plan is a super-large aircraft plan that has been approved by AVIC No. 2 Group in 97 years, and is based on the technology learned from the An-225 "Dream" giant transport aircraft purchased from the Antonov Design Bureau. At the beginning, the target was Airbus's A3XX plan, which was later the A380 plan.

Airbus' A380 will become the largest commercial aircraft with passenger capacity ever built in human history, with a transportation capacity of 525 people in a three-class cabin layout and a transportation capacity of 853 people in an all-economy cabin layout, allowing the Airbus A380 to surpass the Boeing 747 and win the crown of the largest commercial aircraft built by mankind.

Compared with Airbus' A380 plan, Lin Hongfei's Beijun 800 plan is larger, with the reference goal of An-225, Beijun 800 at the beginning of the design of the goal is to provide a single space equivalent to A3XX under the premise of transporting 826 people, which is also the origin of Beijun 800. If necessary, using the all-economy layout, it will be possible to reach a terrifying transport capacity of 1400 people!

But again, the difficulties encountered in this huge project are directly proportional to the size of the project, and the company has only now begun to enter the prototype manufacturing stage, even according to the most optimistic estimates, since the establishment of the project in '97. The prototype will not be built until the end of '06 at the earliest, and the first flight will not be until 2007 at the earliest. Wait until the North County 800 is complete and has obtained the airworthiness qualification and officially put into commercial operation. It will have to be after 2009.

This is still the most optimistic estimate, and even if any one of these links goes wrong, it may lead to a significant delay in time.

After experiencing the painful lessons of the Yun-10 that year, the view that "heavy aircraft represent the cutting-edge strength of a country" has become the consensus of the core and high-level of the entire republic. The reason why Beijun 100 and Beijun 200A/B can occupy such a huge market in China is that in recent years, in order to ensure the theory of AVIC Second Group, the country has resolutely not allowed Boeing and Airbus to expand their market share even at the expense of the speed of development of the domestic aviation industry. It is to protect the second group of AVIC and ensure the smooth progress of the North County 800 project, which is like a bottomless pit.

It's just that the old general Huaqing never thought that Lin Hongfei's ambition would be so big, and he actually wanted to convert the Beijun 800 into a doomsday plane of the republic.

But think about it carefully, even if the North County 400 is refitted, the time will be pushed to almost 10 years later, and the North County 800 modification is probably fifteen or six years later, under the premise of a difference of five or six years, it is obvious that the North County 800 platform is much better than the North County 400 platform, and when special circumstances occur, the North County 800 can play a greater role than the North County 400.

After being stunned for a while, the old general silently spoke, "What about the engine?" As far as I can tell, your BD2000 engine seems to be stuck. ”

"Last month, the problem of materials, three-dimensional manufacturing process of fan blades and mathematical model of the outer duct was just solved, and the most difficult obstacle has been solved, and it is expected that the prototype will be built in 06, which is just the same as the North County 800 for testing."

BD2000 turbofan engine is a new generation of large bypass ratio turbofan engine developed by AVIC Second Group after BD1000 and BD1000-B turbofan engines, inheriting the advantages of high reliability of BD1000 and BD1000-B, and absorbing many advanced designs on D-36, its bypass ratio has been greatly expanded from 4.5 to 4.8 to 5.4 of BD1000-B, and the maximum thrust has also been expanded to 17 tons to 25 tons.

Although the size of the North County 800 is similar to that of the An-225, the maximum design take-off weight is not as perverted as the An-225, so that the maximum thrust model among the four BD2000 series engines can meet the design requirements, and it will not be like the An-225 with six engines.

It's just obvious that such an advanced engine is still a little ahead of the republic's aero engine industry, the whole project was approved in 94 years, and the design of the core machine was completed in 02 years, but since then it has been stuck in the material, the three-dimensional manufacturing process of the huge fan blades and the mathematical model of the outer duct, and only one three-dimensional manufacturing process of the fan blades was solved in a few years, until last month, the third generation of single crystal blades was finally successfully manufactured. It was only by taking advantage of the opportunity of working with Rolls-Royce that he was able to steal the mathematical model of the duct to solve the problem.

For Lin Hongfei's ability, General Huaqing is still trustworthy, since this kid said that he solved the most difficult roadblock of the BD2000 engine, then it must be the most difficult roadblock, I believe that this kid does not dare to joke about this kind of thing, and said slightly, "Since this is the case, then I will go back and report to the chiefs to see what the chiefs mean." ”

Obviously, in terms of the platform for the modified Doomsday aircraft, compared to the North County 400, it is obvious that the North County 800, which has a larger volume and take-off weight, is more suitable.

Lin Hongfei breathed a sigh of relief!

General Huaqing's statement is not only that he chose the Beijun 800 aircraft, but also that the country has recognized the Beijun 800 aircraft and will pay for this aircraft in the future...... As the Republic grows stronger, the North County 800 will also become a way for many countries to "pay the D fee" to us.

For example, in the United States, when many countries buy Boeing planes and various types of US military equipment, they are actually "paying a D fee" to the United States.

"But boy, do you want to be so shrewd?" The old general, who was about to get up, suddenly looked at Lin Hongfei with a smile, "Don't fight with this kind of caution in the future, this is not a good habit." ”

"Yes!" Lin Hongfei hurriedly responded, and the sweat suddenly came down: Sure enough, they are all old monsters, and they can't hide their little caution from them.

————————————————————————

"Hongfei, I'm in big trouble this time, you must help me ......" On the phone, An Lele almost cried.

"What's wrong?" Lin Hongfei's heart suddenly "groan~~", he glanced at the international call displayed on his mobile phone again, and a not very good idea instantly came out of his heart, and the frightened Lin Hongfei's face changed, "You won't make Maria's belly bigger, right?" ”

"What are you talking about," Lin Hongfei was taken aback by the fat man's words, but he didn't know that the fat man was almost paralyzed by Lin Hongfei's words, "Maria's father is the Emperor, even if I have a good relationship with her, but if I dare to provoke her, his father will not tear me apart?" ”

If you want to say that this fat man, he has been mixing well with the woolly bear over the years, and I don't know how Lu Dao did this product, he actually became good friends with his wife Aurora and his eldest daughter Maria and the second daughter Catherine of the Emperor, with such a powerful "backer", the fat man's business in Russia has been smooth, and now this goods suddenly ask for help from himself, then blame Lin Hongfei for thinking crookedly: The daughter of the Emperor Pu, can anyone provoke it?

"Not Mary? That's Ekaterina? Lin Hongfei cautiously asked again.

"It has nothing to do with Maria or Catherine!" The fat man is almost crazy.

"It's good that it has nothing to do with them," Lin Hongfei breathed a sigh of relief, "Say, what's going on?" ”

"That bastard Luzhkov wants our big Cherkizovsky market."

Through the phone, Lin Hongfei could clearly hear the sound of Anle grinding his teeth on the other end of the phone.

"Cherkizovsky Market? An ant? Lin Hongfei was stunned for a moment, and in the next second, his voice was an octave higher, and he said angrily, "Luzhkov, that bastard, is this trying to find death?!" (To be continued......)
