The international status of aircraft engines not only has a huge impact on the civil aviation system, but also determines to a large extent the true level of a country's national defense industry in science and technology. Moreover, it also has an important role in improving the level and strength of national defense.
Extremely significant significance.
There are many countries in the world that can make cars and car engines, and there are also a lot of countries that can make rockets and missiles, but there are very few countries that can make excellent aircraft engines.
If Dongchen is not included, China's achievements in this ultimate field of industry are very lackluster. Over the past few decades, whether in the civil aviation or military fields, the domestic manufacturing level has gone from being unmanufactured to barely manufactured.
The situation, what does it mean to make something reluctantly? To put it in the most vulgar and practical way, it means you have to throw away the goods compared with others.
Whether it is thrust-to-weight ratio, fuel economy, safety, reliability or tolerance, domestic products are all inferior to Russian manufacturing processes, and are not even as good as those of the former Soviet Union. In fact, Russia itself has now fallen behind in the field of aero-engines.
A second-rate country, let alone China? To use the simplest analogy, an American engine can accumulate 10,000 flying hours in the sky before being overhauled, while an American engine can be scrapped after 5,000 accumulated flying hours. Such a strong contrast
, has always highlighted China’s weakness in the field of aerospace engines.
In the blink of an eye, Dongchen has transformed from an enterprise with no relevant experience to the top in the industry. Although all of Dongchen's current products are developed around civil aviation systems, it has gone through civilian, military, and mixed military and civilian applications.
From the perspective of Western countries, Dongchen already has the ability to produce high-end military aircraft engines. This can be seen very clearly from Dongchen’s design level, manufacturing process, material advancement and overall performance. Aero-engines
There are simply four types: turbofan engines suitable for large civil aviation, cargo and transport aircraft, turboprop engines suitable for large take-off weights and slower speeds, turbojet engines suitable for military fighters, and turboshaft engines suitable for helicopters
.
From the source, the technical scalability of these four types of engines is almost the same as that of automobile engines. They are nothing more than naturally aspirated engines, turbocharged engines, supercharged engines and even supercharged engines with added nitrogen to accelerate combustion. Once
Mastering the common technology of high-end, then we can manufacture all this series of products. This is why Mercedes-Benz can manufacture all the engines from naturally aspirated engines to engines suitable for F1 racing cars, and the level is at the same level.
They are at the top of the world, and if you expect Lifan to be able to conquer all of these lines, it's best to wait until Lifan builds its naturally aspirated engine.
It is also for this reason that Western countries attach great importance to Dongchen's test flight. If Dongchen succeeds in this test flight and announces full coverage of the entire civilian mainline passenger and cargo aircraft engine field, it will not take long for Dongchen to be able to build a larger engine.
F22 more powerful turbojet engine.
Zhang Wenhao knew that he would not be able to avoid such doubts and speculations. Even Director Liu implicitly expressed the wishes of the top management, that is, when will Dongchen prepare to start the research and development and production of turbofan engines?
In Zhang Wenhao's mind, the answer will take at least some time.
At this time, sitting in the BBJ2 business jet, heading to Seattle with Zhang Wenhao, there were three strange faces that Zhang Wenhao was not familiar with. They were from Chengdu, Shenyang and China National Aviation and other state-owned enterprises with strong defense backgrounds, and they were all from these three companies. Chief engineer responsible for engine design and development.
These people were all arranged by Director Liu. Zhang Wenhao could not refuse, and they rarely talked to Zhang Wenhao, because Zhang Wenhao knew in his heart that the purpose of these people following him to Seattle was to be the most attentive bystander and observe Dongchen. How high has the current aviation engine manufacturing strength reached?
Zhang Wenhao originally thought that having some additional third-party personnel would be a headache for him, but it was only when the plane landed at Boeing's test field in Seattle that Zhang Wenhao truly realized how complicated this test flight was. powerful.
Excluding reporters, Boeing Military Aircraft Company, Lockheed Martin, Pratt & Whitney and other three major pillar companies of U.S. military aviation all sent dedicated personnel to visit and study and provide necessary assistance. For Raymond, it was a direct He cannot refuse orders and arrangements from the White House.
As soon as the two met, they exchanged bitter feelings about each other. Raymond was afraid that Zhang Wenhao would be angry because of the sudden increase in the number of people on his side. As soon as he got the opportunity to talk to Zhang Wenhao in private, he said apologetically: "Zhang, I'm so sorry. I can't refuse these people from third parties."
Zhang Wenhao nodded and said calmly: "Understood, I feel the same way."
Raymond then asked: "Did China also send people to participate?"
Zhang Wenhao smiled helplessly and said: "If you want to participate, just participate. Originally, what we wanted to test were civilian engines. These engines will be sent to all parts of the world sooner or later. Governments and defense departments around the world can easily obtain them. In this case, it is better to start from Involve them from the beginning and maybe bring some government orders to Dongchen."
Raymond also spread his hands helplessly and said: "You know, what they are more concerned about is whether Dongchen now has enough strength to produce pure military aircraft engines, especially fighter engines."
Zhang Wenhao smiled and said: "What's the point of them caring about this? If Dongchen doesn't get involved in the production of military engines, what's the point of having such strength."
Raymond explained: "They always have to measure a country's potential space for improving its national defense level. If Dongchen shows sufficient research and development capabilities, I think many countries that list your country as an imaginary enemy will immediately allocate funds to accelerate the improvement of their own countries. I think you also have some understanding of the strength in this area and the history of the Cold War. The two sides are completely like girls who are jealous of each other. If you buy a Chanel today, then I will buy a Versace tomorrow. If you sleep with a male model today, I will buy one tomorrow. If you sleep with an actor and I know that you are pregnant and I don't have a boyfriend, then even if I am artificially inseminated, I will get pregnant as soon as possible and not lose half a step."
Zhang Wenhao laughed at Raymond's ridicule and said: "Raymond, your metaphor is really insightful!"
"To be honest!" Raymond smiled and said: "This rule also applies to Dongchen. Do you dare to make a bet with me? If the three new engines launched by Dongchen are a big success this time, Pratt & Whitney, Companies such as Rolls-Royce, Snakma, Rulica Saturn, and Mitsubishi Heavy Industries will all receive government funding to develop better military engines for various parties. Moreover, even countries like India will also receive funding from the government. Spend a lot of dollars to ask the United States and Russia for help, either by introducing better engines or seeking joint research and development."
Zhang Wenhao couldn't help but laugh out loud and said: "The so-called joint research and development in India is actually just a rip off of giving money, right?"
"That's right." Raymond nodded: "They don't have enough manufacturing capabilities. They usually use joint research and development to satisfy their self-improvement mentality. Generally speaking, countries such as the United States and Russia will only bring out their second-tier technologies.
, and then get more US dollars from India, and then conduct so-called secondary research and development, and give the second-tier technology to India in return.”
Zhang Wenhao nodded and said with emotion: "According to what you said, as long as Dongchen succeeds this time, the countries you just mentioned, such as the United States, France, Japan, India, and Russia, will immediately accelerate their development of military aviation engines.
Research and development work? Don’t they wait until Dongchen actually builds a military engine before making a decision? "
"No." Raymond said very firmly: "Although the arms competition between countries now is not as crazy as during the Cold War, everyone also knows that in areas of great strategic significance, we must master a certain amount of advance.
Quantity, that is to say, I will not wait until your next generation product comes out before I catch up. As long as I think you have the actions or capabilities and advantages to develop the next generation product, I will immediately start my own research and development. In this way, even if I cannot catch up,
When I come back, I will only be half a generation behind you at most, and I won’t be far behind you by a generation.”
Zhang Wenhao secretly laughed in his heart. If what Raymond said is true, then after Dongchen’s test flight, I am afraid that the additional expenditures of these countries in the field of military engines will exceed at least ten billion US dollars. This is also equivalent to advancing this field invisibly.
However, by that time, the domestic manufacturing level and overall strength will probably be even further behind, right? After all, powerful countries like the United States and Russia can exert far greater efforts if they have a better foundation.
Higher than domestically.
At this time, Zhang Wenhao secretly thought that if the Dongchen engine test flight was successful this time, and these countries would immediately make corresponding catching-up actions as Raymond said, then he should also consider changing Dongchen Aviation from a pure
Civilian companies have turned to both military and civilian companies. For example, companies like Pratt & Whitney previously used their engines not only on various models of Boeing and Airbus, but also on F-15, F-16, F-22, F
-35 advanced fighter models, in fact, the three giants of the world's aviation engines all have a considerable degree of military pedigree. Rolls-Royce also provides engines for the F/A-18 Hornet carrier-based aircraft, and the F-35 engine also has its own
Even the engine used by the British Harrier fighter jet was jointly developed by him and Pratt & Whitney. GM is not idle either. Half of the F-16s use GM engines, and the Indian Air Force is also one of GM's major customers.
one.
Dongchen has now basically defeated the advantages of the three giants in the field of civilian engines. If they really want to catch up in the field of military engines, then Dongchen will use practical actions to make them realize that no matter how hard they catch up,
It will all be in vain
The whole country is paying close attention to the news that Dongchen has chosen to join forces with Boeing for test flights in Seattle. At the same time, more and more "guest guests" are pouring into Boeing's test flight center in Seattle. Although Boeing and Airbus are sworn enemies,
But this does not mean that the United States and Europe are mortal enemies. Rolls-Royce is here, Snecma is here, and even Mitsubishi Heavy Industries, which had made secret deals with Zhang Wenhao before, was cheated by Zhang Wenhao with new alloy steel without realizing it.
Here too.
It’s a visit anyway. A visit outside is also a visit, and a visit in front of you is also a visit. Zhang Wenhao is not worried that someone will be able to copy the core technology of Dongchen Engine. Even if it is dismantled, it will not be possible. At least these countries have not been able to do so for more than ten years.
It was impossible to do it within a short period of time, so Zhang Wenhao was very generous about it.
Since Boeing has always had very strict standards for test flights, although they do not produce engines, the performance of the engines determines the performance of their aircraft in the sky. Therefore, Boeing has always had a full set of engine test platforms. When the engines are hoisted on their own
Before flying the aircraft, they must know the weight, maximum thrust, fuel consumption and reliability of the engine and conduct a series of tests. After confirmation, they will conduct a test flight according to the specific parameters. It may even need to be changed according to the engine.
Aircraft counterweight.
Although Zhang Wenhao has given Boeing all the data about these three engines, for safety reasons, Boeing still needs to verify the specific parameters of the engines first and draw a final conclusion that he has seen with his own eyes.
Although the ground test was only open to a few media from China and the United States, the entire onlooker team reached an astonishing size of thirty people, more than a dozen of whom were third-party personnel who came to make soy sauce, and the first test team
, which is also the maximum thrust and fuel consumption of Dongchen engine.
These two tests can be completed at the same time. Maintaining the maximum thrust of the engine, not only can the maximum thrust of the engine be obtained, but also the fuel consumption under the maximum thrust of the engine can be obtained by continuing to run for a period of time. Zhang Wenhao hugged his shoulders and acted completely like a bystander.
From the angle, I watched the Boeing team tinkering around with these three engines all day long, and finally came to the conclusion that the maximum thrust of Dongchen’s three engines is no different from the design thrust and actual thrust data given by Dongchen.
The comprehensive fuel consumption is the same as that of DC1-1. Compared with the current most advanced engines with the same thrust level, it is about 40% lower.
The expressions of more than a dozen members of the Soy Sauce Group dimmed instantly when the results came out, and one sentence was written on each person's face: "He's just kidding."
It's really impossible to play. Dongchen not only has better design capabilities, but also has materials and manufacturing processes that others cannot imitate. Even if Dongchen's engine is completely dismantled and all parts are completely imitated 1:1, in the end
The manufactured engines are simply not comparable to Dongchen's engines, and even Dongchen's special design cannot be used at all if the materials and manufacturing processes cannot be guaranteed.
Companies from the United States, Britain, France, Japan and other countries have tried to imitate Dongchen automobile engines, but just one thing made them unable to succeed. That is, the engines they manufactured according to Dongchen's specifications could never achieve the durability of Dongchen engines.
Pressure and heat resistance, maintain the same pressure in the combustion chamber, Dongchen engine runs perfectly, but the engine they make will collapse in less than five minutes, the same is true for aviation engines, Pratt & Whitney and General Motors also secretly copied Zhang Wenhao and sold it to American Airlines
The company's engine has come to the conclusion that imitating Dongchen is a road that will never work.
Pratt & Whitney's most high-end military engine designer told the U.S. government after dismantling and studying the Dongchen engine that if Pratt & Whitney had Dongchen's manufacturing process and materials, without changing the original design, the F-
The F119-PW-100 turbofan engine used in 22 can increase the thrust by at least 20%. If the F119 engine is slightly changed and the F119 is reduced and lightweight, the thrust will not change, but the engine's fuel consumption will also be reduced by more than 20%.
.
For military aircraft, fuel consumption is an indicator that can kill everything in an instant.
What is combat radius? To put it simply, combat radius is the farthest distance your fighter jet can fly while still flying back after taking off for combat. If it can fly 3,000 kilometers with a full load of fuel, then the combat radius is less than 1,500 kilometers.
, about 1,200 kilometers, the combat radius of fighter jets cannot be compensated by tankers, because the real air combat is not the work of one or two fighter jets, but dozens or hundreds of fighter jets fighting together. In this case
, the tanker is of little significance.
This is one of the reasons why the military around the world is paying attention to Dongchen's test flight. If Dongchen has the ability to maintain the thrust of the entire series of engines and reduce fuel consumption by about 40%, once they build fighter jets, they are lucky enough to use this technology.
, then the combat radius of the fighter jet will be increased by nearly 40%. Take the J-20 as an example. The current maximum combat radius is said to be nearly 2,000 kilometers. If this rumor is true, then the J-20 takes off from an inland airport in eastern China and operates
The radius is far from being able to cover Tokyo, but if it is increased by 40 or even 30, it can cover 70% of Japan's land. If it takes off from an airport in the southwest, it can cover the entire territory of India. Even if its combat radius is not that high, it can easily reach 30-30%.
The room for improvement of 40 is enough to scare others.
And all parties are worried about more than just the combat radius. Because Dongchen is in the field of civil aviation, he focuses his attention on fuel economy. What if Dongchen changes his perspective on military engines? He does not pursue fuel economy.
sex, and is intended to increase the thrust-to-weight ratio of the engine. What changes will that bring?
The thrust-to-weight ratio of the engine means the ratio of the engine's thrust to its own mass. If the weight of an engine is two tons and the thrust-to-weight ratio is 10, then the maximum load that this engine can achieve is 20 tons. If it is a single engine
Fighter, then the maximum take-off weight of the aircraft is 20 tons. This 20 tons of weight is quite precious. The aircraft's own weight, fuel weight, pilot weight and combat load weight are all included. However, if Dongchen has the ability to improve fuel economy
What will happen if the thrust-to-weight ratio is reduced and the thrust-to-weight ratio is increased? Assuming that the thrust-to-weight ratio is also increased by 40, then the thrust-to-weight ratio will reach 14, and the maximum take-off weight of this aircraft will reach 28 tons, which is more
With the precious weight of 8 tons, it can carry more combat loads and assemble larger and more effective avionics equipment. The extra 8 tons of weight is equivalent to adding a few more equipment slots to the opponent in online games. He can
Carry more equipment to improve your overall combat effectiveness.
Now, the four engines before and after Dongchen have maintained Dongchen's high standards. This proves that Dongchen's technology is very mature. It is not just limited to DC1-1, but has enough room for technological expansion.
, this made the members of the soy sauce group present feel a deep sense of powerlessness and crisis. (To be continued. If you like this work, you are welcome to come to (this site) to subscribe, reward, and support.
