Among the various weapon models, Zhou Yan focused on two: one is a scramjet engine, and the other is a dual-pulse ramjet engine.
The models of the two engines were copied by Zhou Yan from the "Air Force·Air Combat" tutorial.
The original mechanism of the dual-pulse ramjet engine is the PL-15 long-range air-to-air missile, a super air-to-air missile that was born because of the beautiful country's trick of local release satellites.
The military-industrial enterprises of the beautiful country have specially created a super air-to-air missile with a range of 200 kilometers.
But what these instigators did not expect was that I, the rabbit, just relied on my excellent imagination to bring out this missile, and then the rogue eagle was dumbfounded...
The other type, the scramjet engine, is much more technically difficult than the dual-pulse ramjet engine.
The Mach number in the working range of the dual-pulse engine is between three and five, while the working range of the scram engine exceeds Mach 10, and the main body carrying it is a hypersonic weapon.
The reason why the scramjet engine is technically difficult is because once the speed of the aircraft exceeds Mach 3, fuel combustion will become very difficult due to the ultra-high intake speed: either use special fuel, like Mao Xiong’s MiG-
25 and MiG-31, the SR-71 that uses alcohol and Eagle sauce uses high ignition point fuel; or it needs to bring its own oxidizer, such as a rocket engine.
In the current world, the only aircraft with a Mach number of six or above in the world are rockets and ballistic missiles. Even NASA, which is very impressive, has only done theoretical verification and is still far from being successful.
After verifying the model, Zhou Yan extracted the data, compiled it into a paper, and posted it to a domestic military forum with strong official background under the name "Zhou Yan".
In order to prevent the vest from being exposed, Zhou Yan used more than a dozen layers of springboards that can automatically remove traces.
After handing out the paper, Zhou Yan went back to prepare for the final exam.
Although Zhou Yan was sure of getting excellent results in the exam, there were too many perverts on the Shouhang campus. In order to avoid capsizing in the gutter, Zhou Yan still made full preparations.
Zhou Yan felt relieved, but a group of administrators on the military forum were completely confused.
After the paper was uploaded, the administrator in charge of section review thought it was a "phishing post" that contained real or fake data to spy on intelligence, so he blocked it directly.
But while waiting for the review, the administrator was confused: Although he is a non-professional, he is still a professional military fan, and he can still grasp many directions, and the paper just mentioned seems to be my blind spot.
The administrator did not dare to make the decision privately. After typing up the paper, he found the "supervisor", the counselor of the military academy.
"This thing is so professional that we can't even understand it..."
The counselor is not an aerospace major, so he can only ask the school for help.
"Isn't this what Ying-chan is doing?"
The school did not dare to neglect and directly transferred the information to the Aerospace Science and Industry Corporation.
After the person in charge of the Aerospace Science and Industry Corporation got the information, he was a little confused: This thing, Eagle Sauce, is still in the technical verification stage, but someone here has already done it? Isn't this nonsense?
But when the person in charge looked at the data in the paper, it didn’t look like it was fake. He handed it over directly to technicians and put it on a supercomputer for simulation.
Soon, the results came out.
"The experimental results are generally consistent with the data in the paper. The differences may be due to the simulation performed by the author of the paper."
"There is no problem with the data. How about we do an experiment?"
The processing capabilities of the aerospace system are naturally extraordinary. In just a few days, based on the data in Zhou Yan's paper, a set of dual-pulse engine was built and put on a high-altitude experimental platform for testing.
"The experimental results are basically consistent with the ideas of the paper. The engine load coefficient can generally meet the needs of actual combat..."
This TM is no longer a pure technical paper, it can be used directly as a weapon development instruction manual.
As soon as the results came out, the Science and Technology Group immediately called the Military Intelligence Bureau and the NSA.
The NSA and Military Intelligence immediately organized personnel to investigate the forum.
After the results came out, all the intelligence personnel let out a long sigh: After the paper was uploaded, it was blocked by the administrator, and there was no possibility of leakage.
However, when the intelligence personnel planned to continue to trace "Zhou Yan", they encountered difficulties: all traces of "Zhou Yan" on the Internet have disappeared...
In the end, the intelligence personnel could only determine that "Zhou Yan" was a patriotic overseas person who was engaged in aerospace engine research and development.
If Zhou Yan knew that the evaluation given by the relevant departments was like this, he would probably be happy, although he was already happy: full marks in all subjects, this was Zhou Yan's explanation for the first semester of his freshman year.
In addition to the results, the winter vacation is about to begin.
In order to reward himself, Zhou Yan Bookstore bought himself a large number of books, mainly related to materials: metals, non-metals, inorganic non-metals, titanium alloys, nickel alloys, and carbon fiber.
Although Zhou Yan has always called "biochemical environmental materials" one of the four major pitfalls in his undergraduate studies, after learning aircraft design, he had to fall into it.
The "shell" of the aircraft - the skin material, involves aluminum alloy and carbon fiber: before the popularity of carbon fiber, the material of the aircraft skin was mainly magnesium-aluminum alloy; after the popularity of carbon fiber, in order to reduce weight, carbon fiber has been used in many places on the aircraft.
The core force-bearing parts of the aircraft, the central wing box at the intersection of the aircraft wings and the fuselage, are made of titanium alloy; the important load-bearing parts of the aircraft are also made of titanium alloy.
The turbofan engines used in aircraft engines use relatively complex materials, including titanium alloys, aluminum alloys, and carbon fiber. However, the core combustion chamber components are indispensable for nickel-based alloys.
The thermal efficiency of the turbofan engines used in jet fighters, an important branch of aircraft, is positively correlated with the temperature in front of the turbine, which results in the combustion chamber temperature of military aviation engines getting higher and higher.
This chapter is not over yet, please click on the next page to continue reading! In this way, the research and development of high-strength materials with high temperature resistance has become a top priority, from nickel-based alloys to single crystal nickel to those that can withstand higher
Temperature of rhenium alloys…
Materials science is a discipline that studies the properties of materials and can be extended to find high-performance materials.
It is rare to have such a hearty learning opportunity, so even on the train home, Zhou Yan is always absorbing nutrients from the materials science textbooks with relish.
Of course, not everyone likes to read during the holidays. The young lady sitting opposite was dissatisfied with Zhou Yan's "disdain" for his own happiness.
"bookworm!"
"He?" Zhou Yan, a student from Shouhang who was walking with him, almost choked on the hot water.
"I said he was a nerd. Is there anything wrong?"
The classmate sitting next to Zhou Yan glanced at the MP3 playing classical music in front of the table, and then looked at the grumbling beauty opposite: "Sister, do you know who he is?"
"Is this guy some kind of celebrity?"
"Haven't you heard of the perverts in the maiden aircraft major?"
The young lady suddenly understood and looked at Zhou Yan with suspicion: "Is this guy the pervert in our school who has perfect scores in all subjects?"
At this moment, Zhou Yan put down the textbook in his hand, glanced at the high school alumni next to him, and then at the young lady opposite who was already blushing: "You two, when you evaluate others in the future, it's best to speak in a low voice.
Point, my headphones are not noise-cancelling headphones after all..."
"Hey, Li Xueba, what book are you reading?"
Zhou Yan closed the book and asked the alumni to take a look at the cover: "Titanium Alloys and Their Processing!"
The alumni looked puzzled. After a long time, they finally uttered: "We really don't understand the world of top academics..."
