Chapter 564: Inquire

When the key was taken, Tan Zhenhua had to obediently follow Song Wenhua to his room honestly. As for the elders who secretly covered their mouths and watched the jokes along the way, they lost the heroic image that had been so powerful and instructive on the venue just now. clean--
What's that? Our Xiao Tan Tan has a thick-skinned face, this is not a problem.
When he came to the room and sat down, Song Wenhua chuckled and asked without a smile: "Good boy, the more I stretch out my hand, the longer my hand is. Actually, even the teacher, I have been inquiring about what project I want to do. I haven't even said anything about it yet. , And it's still a confidential project, say, how did you know?"
Tan Zhenhua quickly denied: "Teacher Song, I don't know anything. The thing I gave you is a model made based on the "J9" that has been dismounted and my imagination. Didn't I tell you before? I am an admirer of Dassault. The old man said at the beginning that a good airplane must be a beautiful airplane. I know that you have been worried about the dismounting of the "J9", so I want to give you a gift. Makes you happy. Of course, I have added my imagination here. I changed it to look a little better on the basis of the "J9". Then I made the model. If it happened to some of your projects, it would be pure coincidence. It's pure coincidence!"
His explanation can be justified, and Song Wenhua really can't imagine that Tan Zhenhua can get his design plan for the "No. 10 Project" that is still in the project consultation stage and is strictly confidential.
Although his design is so similar to the model sent by this kid.
Is this really a coincidence?
Song Wenhua looked up and down Tan Zhenhua with suspicious eyes, wanting to see some clues from his face.
It's a pity that the 18-year-old young man in front of him lives in his body but a soul older than him. That is really an old fox who has cultivated for many years. How can he easily see through it?
So, after watching for a long time, he didn’t see any flaws in Tan Zhenhua’s face, and finally he had to grunt from his nostrils: "You pass, but what's under the air inlet of your model airplane? Drumbag? How can there be such an air inlet in this world? Just make such a thing for the sake of good-looking, all nonsense, do you really think that to be an airplane, as long as it is good-looking?"
"This..." Tan Zhenhua was speechless for a while.
Of course he knows what that drum bag is. It is the top scientific research achievement in fighter design. The scientific name is "Supersonic Inlet Without Surface Layer" and the English name is: Diverterless Supersonic Inlet, or "DSI" for short, which is fluid mechanics. The most cutting-edge scientific and technological achievements, compared with other types of traditional air inlets, this design has the characteristics of simple structure, light weight, low resistance, and small radar reflection area. Don’t think it is just a small bulge, but this bulge The shapes, sizes, materials, and craftsmanship are all real black technologies. Even before Tan Zhenhua was reborn, there were only two countries in the world that had mastered this technology and were able to apply it to the latest fighter aircraft-the United States and China.
This technology was first studied by Lockheed Martin in the United States in the early 1990s and was used to replace traditional supersonic inlets. After adopting this technology, it is possible to eliminate the complicated mechanisms related to the control of the boundary layer in the traditional air inlet: boundary layer isolation plate, vent system, bypass system, thereby greatly reducing the manufacturing cost of the aircraft, and can greatly reduce the aircraft's cost Structural weight.
In the early 21st century, Huaxia completed the research and verification of this technology on the "Fierce Dragon" fighter aircraft exported to Pakistan Railway, and applied it on a large scale to its latest fighter aircraft, starting from the "J-10" fighter. Starting with the first major model modification of the fighter-"J-10 B", almost all the new generation fighters of China adopted this design.
Of course, the technology that the rabbit has mastered and turned into cabbage is removed from the list of "core technology", that is also a matter of course...
But it's only 1982, and even the arrogant Lockheed Martin company hasn't started the research of this technology, so Xiao Tan Tan wants to identify a relative without a source. What can I do?
It seems that I have to come up with fame stunts.
The second son of Tan opened his mouth and started running the train.
"Mr. Song, this is actually the case. You also know that although my major is electronics, I am very interested in aviation, and the recent large investments are related to this industry. When I first came to Xiangjiang, Let the "Red Flag Fund" recruit a working group to collect and sort all aviation-related information. In their work, they occasionally learned a piece of information, that is, Lockheed Martin from the United States. The company is pre-researching a new type of inlet, which seems to have achieved some results. This type of inlet is compared with the traditional Pitot tube inlet that focuses on subsonic performance and the two-dimensional adjustable tilt that focuses on supersonic performance. For the plate inlet, it can take into account the advantages of the two. Moreover, because the inlet has no adjustable accessories, it is lighter in weight and more convenient to manufacture, which is the requirement of design ability, material level and processing technology. Very high."
Seeing what Tan Zhenhua said was true, Song Wenhua couldn't help being solemn, because he heard several very important messages from Tan Zhenhua’s just now: the pre-study of the U.S. countrymen, and the consideration of both subsonic and supersonic ranges. Performance and lighter weight.
Well, I have to say that, compared to the silly Soviet Russian goods, the weapon design of Eagle Sauce is indeed highly respected by rabbits, and to a large extent leads the trend of the world's latest technology.
Therefore, on Tan Zhenhua's previous life network, the majority of military fans mocked themselves and said that rabbits are the biggest rice noodles, and they crossed the river by touching the eagle sauce. There are at least three points of truth in this statement.
Therefore, Tan Zhenhua said that this technology originated from the United States, which immediately attracted Song Wenhua's attention.
Moreover, Song Wenhua believes that Tan Zhenhua is definitely not slanderous, because the two terms he just mentioned, Pitot tube inlet and two-dimensional adjustable inclined plate inlet, and their corresponding performance characteristics are correct. For the layman of aviation, it is not easy to do this.
Well, although Xiao Tan Tan has recently made a big deal of money, and the investment projects are all related to the aviation industry, in the eyes of Song Wenhua, his named student is a layman in the aviation industry.
Therefore, Tan Zhenhua must have obtained the exact information through some channels, and inferred from the timeline, what he said should be the truth, otherwise, it would not be able to explain it anyway.
Then this matter must arouse enough attention, because if Tan Zhenhua said it is true, then this technology is too important to him.
In Song Wenhua’s mind, I am afraid that there is nothing more important than successfully winning the "No. 10 Project", and whether the "No. 10 Project" can be successfully won is obviously closely related to whether his proposal can impress the military. .
Judging from the current development of international fighter planes, considering the actual situation of many wars that have occurred, in fact, most of the air battles occurred in the transonic range, that is, the range from high subsonic speed to low Mach number. The afterburner to the high Mach number range is more to track or get rid of the needs of the enemy aircraft. Therefore, the maneuverability of the fighter aircraft in the transonic range is actually one of the important factors to be considered in the design of a fighter aircraft. In this range, the fighter aircraft The instantaneous disc, steady disc, nose directivity, and overload capacity of the fighter determine the combat performance of the fighter. Obviously, in order to improve these capabilities, all designs must be tilted toward this.
However, China has exceptions.
Because China’s current imaginary enemy is Soviet Russia, the most important combat mission of the
No. 10 Project
is to intercept the Figure 22M
Backfire
strategic bomber that uses high-altitude and high-speed penetration as the main combat mode!
You know, the maximum flight speed of this kind of bomber has reached Mach 2.3. If the fighter you design can't beat it, then it's strange that the troops can see what interception operations are!
Therefore, for "Project Ten", high-altitude high-speed performance is actually a hard indicator. However, in traditional fighter design, it is difficult to balance high-altitude high-speed capability and transonic combat capability in all aspects. Yes, this forms a paradox and becomes the relationship between fish and bear's paw.
And Tan Zhenhua actually said that this new type of inlet in the United States in pre-research can take care of both?
What's more, Tan Zhenhua also conclusively claimed that this new type of inlet can reduce the weight of the structure?
You know, when it comes to designing a fighter, it is almost the designer's instinct to care about every gram of weight!
What's more, who doesn't know that China's aero engine came out of the mother's womb with faults!
It is also a huge temptation to be able to reduce the weight by one point and reduce the requirements for the engine by one point.
Song Wenhua automatically ignored some obvious unreasonable elements in Tan Zhenhua's narration, because there were more important things that completely occupied his attention, so he decided to get to the bottom of it.
