   Chapter 713 Horror Data of Yinglong Aerospace Aircraft

  G550 took off and flew towards the South Sea Island smoothly.

   On the plane, He Ting kept asking about aerospace plane engines and other advanced technologies.

   Director Wu and He Ting, although they are not in the same system, they are of different levels after all.

  He Ting reported directly to the elders, not himself.

   So He Ting spoke, and Director Wu could only listen.

   As Ren Heting asked, Gu Song didn't say much. Later, he made an excuse to get up too early and started to close his eyes to rest.

  The plane landed, and the car that Flint Aerospace arranged to meet directly pulled the person to the Changwen headquarters.

"The time spent here in Changwen will be longer, so let's go to the apartment and sort out the experience first. The weather is different, so change your clothes first, and Zhao Hongtao and the others will lead you to familiarize yourself with the environment here, and then Meet at the cafeteria. The formal introduction will be held in the conference room in the afternoon."

   These words were addressed to Li Wei and other astronauts.

   Director Wu felt that he was being treated like a normal team member. Of course, he wasn't wondering if the accommodation was the same, but he saw that He Ting had already dragged Gu Song inside, but he didn't greet him at all.

   So he could only go to the apartment area with everyone, and go to Gu Song and the others after he was ready to put down his luggage.

  …

  He Ting pulled Gu Song to the engine test bench.

   "What's the hurry!" Gu Song was helpless, "The key task this time is to test the flight, not to discuss technical points."

  He Ting said with a calm smile: "I only noticed that you have intensive tests on your side before. Looking at such a large data reflection, I thought that the Zhulong rocket engine was improving. Who knew you were doing it so fast?"

"Oh...then some of these tests are indeed the improved tests of the Zhulong 2 rocket engine." Gu Song looked at He Anzhi who came to greet him, and said, "To be honest, this aerospace aircraft engine is suitable for space transportation. , but it is not suitable for you to perform some tasks. After all, the technology is still the first generation, and the endurance and maneuverability indicators are not good. "

  He Ting didn't care: "Even if this engine itself is not suitable, but if you want to achieve single-stage orbit, you must have overcome a lot of technical difficulties. Some of those solutions can also be used in other places!"

  Gu Song looked at him strangely: "The problem is, these technical problems... Do you understand?"

  He came to a high position, but he was not from the scientific research system. If you tell him about such cutting-edge technology, he can't understand it, right?

  Gu Song reacted after a while, looking at the young man who followed him: "This brother Fei..."

  He Ting gave him a thumbs up in admiration: "Fei Jing, the backbone of the Veyron team."

   The young Fei Jing nodded.

  Gu Song was shocked: "Brother Fei, your name..."

   "I can't help it, my parents started it." Fei Jing's expression did not change, as if he was used to it.

   "You really came prepared... Since that's the case, Mr. He, take out the test data and introduce it to Commander He and Brother Fei."

   When he arrived at the reception room in the main building, He Anzhi brought his laptop and fiddled with the projection.

   "Very well prepared!" He Ting praised.

   "It was originally just a test flight. It would be done by borrowing two astronauts. It had to be so complicated." Gu Song muttered, "With such a big fanfare, you must be prepared."

He Ting said a strange thing: "The prototype of the aerospace plane has been developed and is about to fly. In your eyes, it is not a big deal. I can't understand it. If you knew this was a monster that entered orbit at a single level, how could it be so simple? Believe it or not, maybe Gu Yuan will come over in two years.”

  Fei Jing silently looked at this long-known young academician and winner of the highest technology award.

   This guy's face really does not care.

  Fei Jing suppressed his curiosity and waited for He Anzhi's introduction.

   A clerk brought tea, and after the door was closed, He Anzhi was also ready. He nodded to Gu Song and said, "The development of an aerospace plane is to solve some of the drawbacks of the launch vehicle itself. In addition, there are lessons from the space shuttle ahead, so when the first design was started, Gu Song took it out. The direction is single-stage orbit."

   He Ting still understands this background.

  The rocket engine is ignited from the ground, and it uses its own oxidant and fuel to ignite to generate thrust. Therefore, it has to carry a large amount of oxidant, which makes the propellant mass account for a large proportion. In this way, a rocket of several hundred tons may only have a payload of about 10 tons.

   No matter how recyclable it is, there are natural limitations.

  He Anzhi said: "The development of the Yinglong aerospace aircraft is divided into three parts. I am in charge of the engine, Fan Yuanbai is in charge of the configuration and design of the spacecraft, and Guo Yue is in charge of the software system. Of course, Mr. Gu is in charge."

   "As for the engine, the route of the rocket-based combined cycle power plant is adopted. This is the schematic diagram of the structure."

   Looking at the picture on the projection, Fei Jing squinted his eyes slightly and watched intently.

  He Anzhi explained: "In the state of low sound speed, the intake ramjet is used. After the initial speed is sufficient, it can be switched to the rocket engine. If you want to subdivide, you can see that it has a total of five working states."

   Fei Jing opened his mouth, looking like he wanted to ask a question, then held back.

He Anzhi continued: "Of course, in the process of designing and completing this engine, a large number of pre-simulation calculations were carried out with special quantum computers and artificial intelligence. There are too many technical points here, such as aerothermal power, processing and manufacturing, mechanics, and material technology. , Turbomachinery... Fortunately, Mr. Gu participated in special plans for precision instruments and machinery, material technology, artificial intelligence and quantum computing at that time. Without the foundation of these aspects, it would be impossible to make this thing a real thing. "

  He Ting remembered Gu Song's "uniqueness" that the old man said, and muttered in his heart that this guy must have prepared step by step.

"I won't introduce the technical difficulties overcome here one by one, let's just talk about the results." He Anzhi looked a little excited, "When this guy works at Mach 5, the specific impulse can reach more than 6,000 seconds. The cooling system is strong and can work all the way up to close to Mach 12, allowing the engine to work in scramjet mode, allowing the rocket engine to start at the highest possible speed and increasing the payload ratio.”

  Fei Jing couldn't help it, and asked, "That is to say, this engine actually includes a solution for a scramjet engine?"

  He Anzhi looked proud: "That's right. But how to design a single ramjet to further enhance its potential, we haven't studied it."

  He asked Fei Jin curiously: "Useful?"

  Fei Jing nodded excitedly, but only said: "Please continue to introduce."

"The final engine, if it is propelled at maximum efficiency, can easily enter synchronous orbit. If it only reaches low-Earth orbit, it can greatly improve the comfort and cause less stress on the aircraft. According to the simulation Look, the passengers in it will feel similar to taking a civil flight."

"Because of the high working efficiency of the engine, the payload of the Yinglong aerospace aircraft can reach 76.5 tons in the designed take-off weight of 425 tons, and the proportion of the payload is 18%! Of course, I am only responsible for the engine. The design and software system of the space shuttle has greatly improved its reliability, and the maintenance time and other costs are much better than those of the space shuttle. In the words of the boss, the idea of ​​​​the design is actually a civil aerospace aircraft. "

  Gu Song nodded and said, "This is for civilian use, and is used for peaceful construction. If you have any needs, you can study and demonstrate it later. But this thrust level, specific impulse, and the requirements for the size of the aircraft are not suitable."

  Fei Jing replied in his place: "It's already very powerful... The commander does not want to realize the strategic use of aerospace aircraft in one step. Many of the technologies in it will be of great reference to our next-generation aircraft design and research!"
