Since the end of World War II, the international situation has entered an extremely sensitive era after a long development over the past few decades, and in this general environment, the nerves of every country are very sensitive, and what is rare is that the whole world has developed peacefully for decades in this highly sensitive state.

In this environment, if a certain party has made great progress in a short period of time, it will have a huge impact on the entire international situation, in this point of view, Nie Minhui's view is very objective, first of all, she does not support Zhang Wenhao to put too much experience into national defense science and technology, secondly, she disagrees with Zhang Wenhao to continue to make high-end technology that is enough to change the world to national defense science and technology, blindly enhance national defense capabilities, is not an outright good thing.

Nie Minhui couldn't help but ask Zhang Wenhao, "Wenhao, if the United States is not the world's largest economy, then what kind of changes will happen to his international status?" ”

Zhang Wenhao frowned slightly, thought for a moment, and said: "Their national defense technology is too powerful, even if they slide down from the position of the world's largest economy, it should not hinder their top status as a superpower." ”

"Nope." Nie Minhui said lightly: "National defense science and technology is only one aspect, Rao is the United States' national defense science and technology no matter how strong, it can not solve the fundamental problem at all, the current era has become stable, if the United States is not the world's largest economy, it is difficult for him to launch a real war of aggression in the first place, otherwise." What he will face may be the hostility and rejection of the whole world; Secondly. After he loses his strong economic capacity, what will he use to ensure their strong national defense technology? When their domestic economy continues to decline, when the national standard of living continues to decline, when the national unemployment rate continues to rise. What do they do to maintain their superpower status? At this point, the Soviet Union back then was the best example, and there was no one of them, the real reason for the collapse of a union was always the economy. ”

Zhang Wenhao nodded thoughtfully. "I understand what you mean, the economic foundation is the foundation of the country. ”

Nie Minhui nodded with a little appreciation and said with a smile: "Blindly developing national defense science and technology is nothing more than reckless military force, and mighty aircraft carriers cannot feed the people." And he himself needs a lot of money to build and maintain, and the most important thing for you now is to achieve more in the economic field, rather than to make more weapons and equipment like a hot potato. ”

Saying that, Nie Minhui said: "This kind of thing is a hot potato, you have two choices now, or, temporarily press him down and keep it in your stomach; Either. It can only be handed over to the government to operate, and once you apply this material to your civil aviation field, then export is inevitable, and Western countries will always pay attention to this, if Dongchen uses the most high-end materials, they will immediately think that this material is also applied to our national defense technology, and at that time, they will see you as a threat. Or an opportunity, if single-crystal superalloys will bring a huge impact to the world, then, you are standing on the cusp. ”

Zhang Wenhao was speechless for a while, and Nie Minhui then asked: "How core is this kind of material in what you have to do?" If we are much worse than the Western countries in this field, then if you catch up with them, you will only put pressure on them, but will not let them beat your ideas, and if you exceed them too much, I am afraid that the situation will not be able to control you. ”

Zhang Wenhao nodded, said: "Although this material is very core, but, as long as it reaches a certain level, it can basically meet the requirements, Dongchen aero engine, the most important advantage, on the one hand, is the combination of a variety of new materials, on the other hand, is the more top design concept and manufacturing technology, alone in the field of single crystal superalloy, as long as it reaches the current international first-class level, it will not have much impact, and even the impact is minimal." ”…,

Nie Minhui smiled slightly and said, "Then this is easy to do, don't come up with too high-end technology, it is enough to be able to maintain a level with Western countries." ”

Zhang Wenhao nodded in agreement, and said, "I know what to do, try not to show off this key material." ”

Nie Minhui agreed: "In the future, we must also ensure that we try to involve as little technology as possible in the military field that is obviously greater than the significance of the civilian field, concentrate on doing your own thing, and develop your own economy, in the current form of Dongchen, it is likely to become the world's most influential private economy." ”

There are three general sections of turbofan engines, one is the economic civil engine with medium thrust and lower fuel consumption that Zhang Wenhao is the first to prepare to produce; The other is the high-thrust engine, this kind of engine is mostly used in large passenger aircraft, cargo aircraft and military transport aircraft, the significance of the military and civilian two fields can be said to be half and half, and the last one is the high mobility engine, which has no meaning at all for civilian use, but it is extremely important in the military sense, and it is the biggest core of the power part of the fighter.

Zhang Wenhao originally planned that the current two engines can be maturely produced and have a certain market base, and then turn to the development of the third engine, but now it seems that the significance is not very great, if they provide too much high-end military technology, it will inevitably drive the structure of the entire national defense field, just like the manufacture of DCC-1800A diesel engine, its appearance, so that the national defense funds in the field of armored vehicles have increased at least 10 billion, not only manufacturing costs and replacement costs, It includes the increased cost of training, exercises, and training of professional maintenance personnel in order to re-adapt the army to the new performance of armored vehicles, as well as the waste of resources of all engines and related spare parts that have been eliminated.

A country's economy determines the amount of money that should be invested in the field of national defense, and the two need to achieve a balance, otherwise, it will only increase the burden on society and the country. With a cost of more than 10 million yuan per unit, and all other related costs. It would also be a huge expense, presumably. The end of all the outfits will require at least tens of billions of dollars to support.

Thinking of this, Zhang Wenhao decided to put down national defense science and technology first, and make every effort to develop the economy, and more high-end national defense science and technology should be considered after the economic development has reached a sufficient foundation.

Rao is Zhang Wenhao to reduce the technical content of single crystal superalloys. Let it only be consistent with Western countries, but this also made the top management excited, and the relevant enterprises directly under the defense department immediately began to carry out trial production and related experiments according to the technology provided by Zhang Wenhao, and promised. Once the materials are successfully trial-produced and have mass production capacity, we will make every effort to meet the needs of Dongchen.

This central enterprise already has the ability to produce single-crystal superalloys, but their technology has been relatively backward, with hardware facilities and relevant experience, when they get high-end technology, they can quickly transform this technology into actual products.

Only a week later, the single-crystal superalloy technology provided by Zhang Wenhao had the strength of mass production and was put into production immediately.

At the same time, Dongchen officially announced to the public. Dongchen Aerospace Engineering Co., Ltd. was officially established, referred to as Dongchen Aerospace Engineering, this company is a wholly-owned subsidiary of Dongchen Group, and its business development direction is the R&D and manufacturing of civil aviation and aerospace equipment, which is the same as Boeing, Airbus and other companies.

This news has also triggered global speculation about Dongchen Aerospace Engineering Company, and it is not difficult to see Dongchen's intention from the name of this company. Most of them are related to aerospace aircraft manufacturing, but the whole world also knows that now Dongchen only has an aircraft engine production line in its hands, in addition, he even has an assembly line that can assemble Boeing 737 passenger aircraft, and the manufacture of an aircraft often requires hundreds of spare parts suppliers, but all relevant companies in the world have said that Dongchen has not had any contact with them, so let alone any cooperation. …,

Airbus, Boeing, Pratt & Whitney, General Electric, Rolls-Royce and other companies have issued congratulations to Dongchen for entering the aviation industry, and among them, the real pressure is still the three engine manufacturers.

Airbus and Boeing are not worried about Dongchen's entry into the aviation field, they guess from the current situation that Dongchen now has the hardware to produce aero engines, perhaps, Dongchen, which has always been shocking, will develop better aero engines, but Dongchen cannot have the strength to manufacture the whole aircraft in a short period of time, so there is no conflict between Dongchen and their business, on the contrary, if Dongchen really develops a better aero engine, it is also a good thing for them, after all, all the aircraft they produce, All engines produced by other companies are used.

The American N host ridiculed Dongchen on the news program, thinking that Dongchen was a great achievement, creating an excellent automobile engine, and preparing to set foot in the world's most sophisticated and high-end engine manufacturing field, if this is the case, then Volkswagen, Toyota and other companies may have already built their own aircraft engines, but at this time, Dongchen announced a surprising news.

Dongchen Group has purchased two civil airliners in use from China Southern Airlines at a high price, a Boeing 737-300 and an Airbus A320-200, both of which are not the most advanced of the two companies, but they are the main models of the two companies, in China alone, there are nearly 1,000 aircraft, and the two aircraft purchased by Dongchen have been in operation for about five years, and what is surprising is that Dongchen is actually purchased at the price of a brand new aircraft.

Dongchen Aerospace Engineering Company, which has not even made an airplane wheel, has not really begun to develop in this industry, and has been a big wrongdoer, which is quite funny in the eyes of the world, however, Zhang Wenhao understands what he needs, and now everything is ready, at most a month, he will be able to let Dongchen's aero engine go off the assembly line, once it is offline, it will immediately carry out various ground tests, after the test is completed, he needs to complete the post-hoisting test, and even the test flight, it is very suitable to have his own aircraft, and, Dongchen's first aero engine is the 737 and A320, two short- and medium-range narrow-body trunk airliners.

China Southern Airlines was quite excited about Dongchen's generous move, and did not hesitate to pull out the two planes requested by Dongchen from the operation echelon, when China Southern Airlines contacted Dongchen and prepared to deliver the planes. Only then did I learn about Dongchen's request for these two planes. Each requires a crew member of this type of aircraft with a cumulative flight time of more than 4,000 hours, and the captain needs to meet the standard of a test pilot of a civil airliner. They flew the aircraft to COMAC's test airfield on the outskirts of Zhonghai City.

For the two groups of crew members, the labor contract will also be transferred from China Southern Airlines to Dongchen's name, for which Dongchen will pay up to 10 million US dollars in compensation to China Southern Airlines, and promise to give the crew an average monthly salary of more than 30,000 US dollars for each flight hour. will receive a hefty subsidy of at least $1,000.

The civil aviation system is different from the military aircraft system, the major airlines have their own best test pilots, and whenever they order a new aircraft from Boeing or Airbus, the test pilots must first receive systematic training from the manufacturer. After the aircraft is delivered, the first test flight, these test pilots, are very high-end civil aviation pilots, however, they do not have many opportunities to act as test pilots, in fact, the aircraft they test fly are all aircraft that have been designed and finalized and mass-produced, which is different from the military. Military test pilots often fly new planes that have never been in the sky, and this work in the field of civil aviation is done by test pilots from Boeing and Airbus, so the salary of civil aviation test pilots is not too high, and most of the time, they are on the front line of operational flights as captains. …,

The average monthly salary is more than $30,000, and the captain's monthly salary is more than $45,000. The most important thing is that this money is only a basic salary, every time they are on duty, they will get a subsidy of 1,000 US dollars from Dongchen for an hour, if they fly normally, a crew member will fly for more than five hours a day, so that Dongchen is simply the most generous employer in the world.

China Southern Airlines has earned a lot of discounts from the two planes, and the transfer of the two sets of crew to Dongchen has given them back the so-called compensation of tens of millions of US dollars, that is, the transfer fee of the pilot, which also makes them make a small profit, so China Southern Airlines is very satisfied with the whole transaction, and very happily sent two crew members who meet the requirements to take off from Guangzhou and fly directly to the test airport in the suburbs of Zhonghai.

After the plane arrived at the test site, it was immediately arranged to stay in a five-star hotel in Zhonghai, and the relevant staff of Dongchen replied to them that there would be no flight mission for the time being, and all the crew members were on half-vacation in Zhonghai, that is, Dongchen was in charge of all expenses, but everyone was not allowed to leave Zhonghai City without authorization, so that Dongchen could be summoned at any time.

While the crew was on vacation in Zhonghai's star-rated hotel, Dongchen's first aero engine had rolled off the assembly line and began ground testing.

The so-called ground test, is to fix the engine in the laboratory, the hard data of the engine for a comprehensive test, this engine is defined by Dongchen as DC1-1, that is, the first DC1 series, the thrust of this engine is not eye-catching, the maximum thrust is only 8000 kg thrust, but for the vast majority of the 737 and A320 series of models, it is completely sufficient.

Although there will be no human error in the manufacture of Xiao Er, that is to say, the design data of the things created by Xiao Er basically do not need to be tested, even if it is tested, the results are infinitely close to the design data, however, the field of civil aviation has always been the most demanding industry, and any test must not be slackened in the slightest.

The design index of the maximum thrust of 8,000 kg has been perfectly confirmed, its weight has been reduced by 26% compared with the engine of the same level on the market, the experimental fuel consumption has also been significantly reduced by 37.5%, and the noise has been reduced by about 30 decibels, which is a great improvement for the environment around the airport and the environment in the cabin.

DC1-1 was tested in a closed test in the laboratory for 16 days, and the results of the test were simply ecstatic to everyone, and the top engineers of COMAC have always been a second-rate level in the world, but now, they turned to Dongchen and witnessed the birth of the world's best aero engine, this huge change, everyone was excited.

It stands to reason that it will take at least more than 1,000 hours of ground testing before the engine can be hoisted onto the aircraft for further ground testing, but Zhang Wenhao is obviously unwilling to wait in the laboratory for another fifty or sixty days, so he ordered people to gather two groups of crew members, and a special person and car brought all these people to the engine laboratory of Dongchen Aerospace Engineering Company, and personally took them to see all the performance of DC1-1.

Only then did these crew members really understand what the purpose of Dongchen's high salary was to hire them, Dongchen did not want to form its own small fleet, but to test this stunned super engine!

A captain who has been flying 737 for more than 20 years blurted out: "It's unimaginable, it's really unimaginable!" Our national enterprise has been able to produce such an excellent engine, I have been dealing with 737 for half my life, and I dare to say that this engine is the most suitable engine for 737! Sufficient thrust, less noise, lighter weight, fuel consumption savings from the thrust level alone, can reach 37.5%, if you convert the weight of the two engines, I think, the actual flight fuel consumption savings can reach about 40%, which not only greatly reduces the cost of transportation, but also greatly improves the maximum fuel range of 737, the conservative maximum fuel range of the previous 737 is only about 4000 kilometers, and now it can guarantee at least 5500 kilometers. (Your support is my biggest motivation.) )
