Since the Xiangrui was launched, Lu Zhou transferred the R&D department of the Space Shuttle Assembly Center from the site to the Jinling Institute for Advanced Study, and established a special aerospace science and technology research institute to study aerospace-related technologies, including electric propulsion systems.

Due to the large number of classified projects, the building of the institute is located at the highest level of security in the entire institute, and is located closest to the core area.

Unlike other research institutes of the Jinling Institute for Advanced Study, the Institute of Aerospace Science and Technology is mainly the Space Shuttle Assembly Center of Star Science and Technology, and the vast majority of the funds are also directly from the account of Star Science and Technology, and do not carry out technical cooperation with other enterprises like the Institute of Computational Materials.

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

With his experience in the 863 program, there is no one more qualified for this position. In terms of strength, no one in the entire research institute is more familiar with the structure of the Xiangrui and the overall design ideas than him, and it is undoubtedly the most suitable choice for him to be responsible for coordinating the relationship between the various project teams.

And Hou Guang did not live up to Lu Zhou's expectations, during the time when Lu Zhou was not in Jinling, he not only completed the overall relocation of the research institute in the shortest time, but also did not leave behind the work at hand while relocating.

On the one hand, the technicians were organized to carry out the modular disassembly of the Xiangrui aerospace aircraft, on the other hand, the damage area was assessed while maintaining the equipment, and the data collected from the last test flight was systematically analyzed, and all the information was summarized in a 20-page report.

After spending two days reading the report and preparing the PPT needed for the meeting, Lu Zhou made a phone call to Hou Guang, and in the No. 4 conference hall of the institute, he convened the technical backbone of the Aerospace Science and Technology Research Institute and held a small meeting.

“…… First of all, I would like to thank you for your efforts during this period of time, and I cannot represent the people of the whole country, but only the president of the Jinling Institute for Advanced Study, to express my most sincere respect and gratitude to you. ”

After a brief opening remarks, the room burst into applause.

Lu Zhou nodded slightly, and soon the applause stopped.

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

"Long story short, I've already read the contents of the report."

"The design of the Xiangrui was successful, but I think there is still a lot to improve."

"According to the results of the overhaul, the wing section and the belly part of the aircraft received more heat than we expected during the re-entry phase, and as analyzed by our excellent engineers, the main reason for this was the excessive speed in the dense section of the atmosphere."

"I have been thinking about this for a long time and have exchanged views with experts I know about it. I think that since the thrust of electric propulsion is relatively 'gentle' compared to that of chemical engines, we can consider abandoning the 'gun-fighting' design of traditional chemical rockets and moving the four auxiliary engines from the tail to the wings of the shuttle, leaving only one main engine in the tail. ”

"At the same time, while retaining a pair of fixed wings, a pair of biaxial auxiliary wings will be added to the aerospace aircraft to suspend and control the direction of the engine's jet."

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

This design is not new, it is basically a reference to the model of the tiltrotor, mixing the advantages of vertical take-off and landing with the advantages of fixed-wing aircraft. However, although this model is not uncommon, it is still the first time that many people have heard of it in the aerospace field.

There was no prohibition on the discussion in the conference room, Lu Zhou paused for a moment and continued.

"With this improved design, we can use the reverse jet engine to actively decelerate the returning aircraft, and balance the influence of gravity to reduce the flight speed to a low level before the aircraft reaches the dense part of the atmosphere to avoid frictional losses."

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

"It's an interesting design...... I will organize people from the technical department to conduct feasibility studies. ”

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

After a pause, he continued.

"FYI."

In the center of the curtain is a conceptual graphic of the tiltrotor spaceplane, and in the suspended window next to it, the altitude of the aircraft, the density of the atmosphere, the flight speed and the state of the fuselage are dynamically displayed, and the gradient curve is drawn in real time.

The part of this that involves calculations is all done by Lu Zhou alone.

As for the drawing of the model and the simulation of the entire flight process, Xiao Ai did it for him through superb code skills.

Staring at the image on the screen, Hou Guang lowered his eyes in surprise and asked subconsciously.

"It's ...... Which company's software? ”

He has been in this industry for so many years, and he has been in contact with many companies that do this kind of simulation program, but he has never seen such a sophisticated interface and dynamics simulation...... Even to the extent of perfection. At least in his opinion as a professional, he can't think of anything else to find fault with.

Hearing Hou Guang's subconscious inquiry, Lu Zhou didn't explain in detail, but just said casually: "I'll find a coder from the Information Technology Research Institute to customize it, and I'll copy it to you after the meeting." ”

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

Don't guess, Xiao Ai must be protesting with him.

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

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

It's not clear which awesome guy can make such a perfect simulation, but having this thing will definitely help them a lot in their work.

"Let's not talk about software...... If the engine is moved from the tail to the wing, it will inevitably affect the failure rate. If it's just to improve mobility, won't it be worth the cost? ”

Lu Zhou shook his head and explained: "It's not just maneuverability, through this design, we can actively reduce the speed of the aerospace aircraft to a very considerable value in the airspace above 30 kilometers, which can not only reduce the risk of the return stage, but also directly reduce the maintenance cost 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 easy to realize this blueprint.

Adding two electrically driven hinges to the flyer wing meant increased structural risk on the wing.

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

There are also materials at the joints, and most importantly, control systems, which also need to be improved.

It is no exaggeration to say that changing it to this is basically equivalent to rebuilding the entire Xiangrui aerospace aircraft project.

Hou Guang frowned, raised his hand and asked: "What about the bidding project of the Space Bureau and the Science and Industry Bureau?" ”

"Of course, we still use the Xiangrui to bid," Lu Zhou replied without hesitation, "The new design plan is our goal for the new year, there is no need to rush this, we have plenty of time to prepare." ”

After hearing this, Hou Guang breathed a sigh of relief.

In the end, Professor Lu still considered the actual situation.

The manned lunar landing project is imminent, and the Space Administration and the Bureau of Science and Industry are about to announce the results of the winning bid. But if it's a project for the coming year, that's fine.

Lu Zhou and Hou Guang both nodded, and there could be no controversy at this point in the meeting.

The PPT continued to be screened, and Lu Zhou briefly talked about the design ideas of this new aerospace aircraft.

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

"I have one more question."

Lu Zhou said generously: "What is the problem, let's talk about it." ”

Engineer: "What's the best name for the new design?" Xiangrui No. 2? Or do you want to number with letters and numbers first? ”

It also doesn't look very formal with the old name.

What's more, the shape of this new aerospace aircraft has been changed to something that even its father doesn't recognize.

But what's it called......

Lightning? It's an escape pod.

Meteor? Sounds a bit unlucky.

Lu Zhou searched his intestines and scraped his stomach for a while, and his heart suddenly moved slightly, and he subconsciously spoke.

“…… It's called Xiaguang. ”
