Chapter 715 The Blueprint of the Tilt Rotor Aerospace Plane

Since Xiangrui went to the sky, Lu Zhou transferred the research and development department of the space shuttle assembly center from the site to the Jinling Institute for Advanced Study, and established a special aerospace technology research institute to study aerospace-related technologies including electric propulsion systems. .

Due to the existence of many confidential projects, the building of the research institute is located at the highest level of security in the entire research institute, and is located closest to the core area.

Different from other research institutes of Jinling Institute for Advanced Study, the Institute of Aerospace Science and Technology mainly corresponds to the Space Shuttle Assembly Center of Xingkong Technology. Technical cooperation with other enterprises.

And the first director of the Institute of Aerospace Science and Technology was naturally Hou Guang, the designer of the Xiangrui.

Based on his experience of participating in the 863 project, no one is more suitable for this position than him in terms of qualifications. In terms of strength, no one in the entire institute is more familiar with the structure of the Xiangrui and the overall design ideas than him. It is undoubtedly the most suitable choice for him to be responsible for coordinating the relationship between various project teams.

And Hou Guang did not live up to Lu Zhou's expectations. During the period when Lu Zhou was not in Jinling, he not only completed the overall relocation of the research institution in the shortest time, but also did not lose the work he was doing during the relocation.

On the one hand, technicians were organized to disassemble the Xiangrui aerospace aircraft in a modular manner; on the other hand, while maintaining the equipment, they assessed the damage area and systematically analyzed the data collected from the last test flight. Sexual analysis, summarizing all the situation in a 20-page report.

It took two days to read the report and prepare the PPT needed for the meeting. Lu Zhou called Hou Guang and called the technical backbones of the Institute of Aerospace Science and Technology in the No. 4 conference hall of the institute. , held a small meeting.

"...First of all, I am very grateful for everyone's efforts during this period of time. I cannot represent the people of the whole country, but only the dean of the Jinling Institute for Advanced Study, to express my most sincere respect and gratitude to you all."

After the brief opening remarks, there was a burst of applause in the meeting room.

Lu Zhou nodded slightly, and the applause soon stopped.

Clearing his throat, he gently placed the 20-page report on the multimedia desk and continued.

"Long story short, I have read the content of the report."

"The design of the Xiangrui is very successful, but I think there are still many areas for improvement."

"According to the analysis of the overhaul results, the wing part and the belly part suffered more heat than we expected during the return to the atmosphere. As analyzed by our excellent engineers, the main reason is that the speed of entering the dense part of the atmosphere was too fast."

"In order to solve this problem, I have thought about it for a long time, and I have also exchanged opinions on this aspect with experts I know. I think that since the thrust of electric propulsion is relatively 'soft' compared with chemical engines, we can completely consider abandoning the 'firecracker style' of traditional chemical rockets." ' design, moving the four secondary engines from the tail of the space shuttle to the wings, leaving only one main engine at the tail."

"At the same time, while keeping a pair of fixed wings unchanged, add a pair of ailerons that can be linked with two shafts to the aerospace aircraft, which are used to suspend and control the jet direction of the engine."

Lu Zhou's voice fell, and whispers of surprise spread in the conference room, and many people had surprised expressions on their faces.

This design is nothing new, it basically refers to the mode of the tilt rotor aircraft, mixing the advantages of vertical take-off and landing with fixed-wing aircraft. However, although this mode is not uncommon, many people have heard of it for the first time when it is applied in the aerospace field.

Discussion in the conference room was not prohibited, Lu Zhou paused for a moment, then continued.

"Through this improved design, we can use the reverse jet engine to actively decelerate the returning aircraft, and balance the impact of gravity, before the aircraft reaches the dense section of the atmosphere, the flight speed will be reduced to a lower level to avoid friction loss."

After listening to Lu Zhou's statement, Hou Guang thought for a moment, got up and said.

"This design is very interesting... I will organize people from the technical department to conduct a feasibility study."

"I have already done the feasibility study, although it is on the simulation software." With a smile on his face, Lu Zhou held the mouse and clicked on a folder, and soon a three-dimensional composition was presented on the screen.

After a pause, he continued.

"for reference only."

Floating in the center of the curtain is a concept graphic about this tilt-rotor aerospace aircraft, and in the window floating next to it is a dynamic display of the altitude of the aircraft, the density of the atmosphere, and the speed and speed of the aircraft. Various parameters such as the state of the fuselage are drawn in real time as a gradient curve.

All the calculations involved were done by Lu Zhou alone.

As for drawing the model and simulating the entire flight process, Xiao Ai did it for him through superb coding technology.

Staring at the image on the screen, Hou Guang rolled his eyes with a slightly surprised expression, and subconsciously asked.

"Which company's software is this?"

He has been in this industry for so many years, and he has also come into contact with many companies that do this kind of simulation program, but he has never seen that the interface and dynamics simulation can be so exquisite...or even perfect. At least in his professional opinion, he couldn't think of anything to criticize.

Hearing Hou Guang's subconscious inquiry, Lu Zhou didn't explain in detail, but just said casually: "I asked the coder at the Information Technology Research Institute to customize it, and I will copy it to you after the meeting is over."

Almost as soon as the voice fell, the mobile phone in his pocket vibrated.

No need to guess, Xiao Ai must be protesting with him.

However, the protest is invalid, and it is impossible for Lu Zhou to disclose its existence at this stage.

Hearing Lu Zhou's explanation, Hou Guang opened his mouth.

Although I don't know who can make such a perfect simulation program, but with this thing, it will definitely be of great help to their work.

"Let's not talk about the software... If the engine is moved from the tail to the wing, it will definitely affect the failure rate. If it's just to improve maneuverability, will it not be worth the loss?"

Lu Zhou shook his head and explained: "It's not just about maneuverability. Through this design, we can actively reduce the speed of the aerospace plane to a considerable value in the airspace above 30 kilometers. risk, while directly reducing maintenance costs after a single launch mission.”

"As for the risk you mentioned, it definitely exists, but I think it can be solved by improving the design."

Although it is easy to say, in fact Lu Zhou also knows that it is not an easy task to realize this blueprint.

Adding two electric drive shafts to the aileron means increasing the structural risk on the wing.

At the same time, in order to ensure the coordination between the two engines, he also needs to develop a more sophisticated electric drive system to prevent the engine from deviating from the original course due to accuracy errors when adjusting the direction.

There are also joint materials, and the most critical control system, these things also need to be improved.

It is no exaggeration to say that changing to this is basically equivalent to rebuilding the entire Xiangrui space plane project.

Hou Guang frowned, raised his hand and asked, "Where are the bidding projects from the Space Administration and the Bureau of Science and Industry?"

"Of course we still use the Xiangrui to bid," Lu Zhou replied without hesitation. "The new design is our goal for the new year. Don't worry about it. We have plenty of time to prepare."

After hearing these words, Hou Guang breathed a sigh of relief.

Finally, Professor Lu still considered the actual situation.

The manned moon landing project is imminent, and the space agency and the Bureau of Science and Technology will soon announce the winning bid results. At this time, it is really not a suitable choice to add complications. But if it is a project for the coming year, there is no problem.

Both Lu Zhou and Hou Guang nodded, and it is impossible to have any disputes at this point in the meeting.

The PPT continued, and Lu Zhou briefly talked about the design ideas of this new aerospace plane.

At this time, the engineer who was taking notes for the meeting pushed his eyes with the pen cap and raised his right hand.

"I have one more question."

Lu Zhou said generously, "What's the problem, let's talk."

Engineer: "What is a better name for the new design? Xiangrui No. 2? Or use letters and numbers first?"

Still using the old name is not very formal.

What's more, the shape of this new aerospace plane has been changed so that even its father doesn't recognize it.

But what to call it...

lightning? That thing is an escape pod.

meteor? Sounds a little ominous.

Lu Zhou searched his stomach for a while, and suddenly there was a slight movement in his heart, and he subconsciously said.

"...Just call it Xiaguang."
