Chapter 714: Blueprint of tilting rotorcraft

Since the launch of Xiangrui, Lu Zhou transferred the research and development department of the Shuttle Assembly Center from the site to the Jinling Institute of Advanced Research, and established a special aerospace science and technology research institute to study aerospace-related technologies including electric propulsion systems. .
Because of the existence of many confidential projects, the building of the Institute is located at the highest level of security of the entire Institute and is closest to the core area.
Unlike other research institutes of the Jinling Institute of Advanced Studies, the Aerospace Science and Technology Research Institute's main counterpart is the Starcraft Space Shuttle Assembly Center. The vast majority of funding also comes directly from Starcraft's account, unlike the Computational Materials Research Institute. Other companies started technical cooperation.
The first director of the Institute of Aerospace Science and Technology was, of course, Hou Guang, the designer of the Xiangrui.
Based on his experience in the 863 Program, no one is more suitable for this position than him. In terms of strength, no one in the entire institute is more familiar with the structure of the Xiangrui and the overall design ideas. It is undoubtedly the most suitable choice for him to coordinate the relationship between the project teams.
Hou Guang did not disappoint Lu Zhou's expectations. During the time 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 leave his work at the same time.
On the one hand, we organized a technician to modularly dismantle the auspicious aerospace aircraft.On the one hand, we assessed the damage area while maintaining the equipment, and systematically performed the data collected on the last test flight. Sexual analysis, all the conditions are summarized in a 20-page report.
After spending two days reading the report and preparing the PPT for the conference, Lu Zhou called Hou Guang. In the Institute's No. 4 conference hall, the technical backbone of the Institute of Aerospace Science and Technology was convened. , Held a small meeting.
"First of all, thank you very much for your efforts since this time. I cannot represent the people of the whole country, but only the president of the Jinling Institute of Advanced Studies. I would like to express my most sincere respect and thanks to you."
After the opening remarks, there was applause in the conference room.
Lu Zhou nodded slightly, and soon applause stopped.
After clearing his throat, he gently put the 20-page report on the multimedia desk and continued.
"To make a long story short, I have read the contents of the report."
"The design of the Xiangrui was very successful, but I think there are still many things that need to be improved."
"According to the analysis of the maintenance results, the wing part and the belly part have withstood the heat during the return to the atmosphere. We have analyzed it, and 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 exchanged opinions with experts in this field. I think that since the thrust of electric propulsion is relatively" soft "compared to chemical engines, we can consider abandoning the" fire "of traditional chemical rockets. 'Design to move four auxiliary engines from the tail of the shuttle to the wings, leaving only one main engine at the tail.'
与 此 "At the same time, while retaining a fixed pair of fixed wings, add a pair of twin-axle aileron wings to the aerospace aircraft to suspend and control the engine's injection direction."
Lu Zhou's voice dropped, and a whispered surprise whispered in the conference room, and many people's faces were surprised.
This design is nothing new. Basically, it refers to the model of the tilt-rotor, mixing vertical take-off and landing with the advantages of fixed-wing aircraft. However, although this model is not uncommon, many people have heard of it for the first time in the field of aerospace.
He did not ban discussion in the conference room. Lu Zhou continued after a pause.
"With this improved design, we can use the reverse deceleration engine to actively decelerate the returning aircraft and balance the effect of gravity. Before the aircraft reaches the dense section of the atmosphere, reduce the flight speed to a lower level to avoid friction. loss."
After listening to Lu Zhou's statement, Hou Guangsi paused for a moment and got up and said.
"This design is very interesting ... I will organize the technical department to conduct a feasibility study."
"I have done the feasibility demonstration, although it is on the simulation software." A smile appeared on his face, Lu Zhou held the mouse, opened a folder, and soon a three-dimensional composition was presented on the curtain.
He paused, he continued.
"for reference only."
Floating in the center of the curtain is a conceptual graphic of the tilt-rotor aerospace plane. In the window floating next to it, it dynamically displays the altitude of the aircraft, the density of the atmosphere, and the speed and speed of the flight. Various parameters such as the state of the fuselage, and a gradual curve graph are drawn in real time.
The calculations involved are all done by Lu Zhou alone.
As for drawing models and simulating the entire flight process, Xiao Ai got it for him through superb coding technology.
Staring at the image on the curtain, Hou Guang's expression pushed his eyes slightly, and asked subconsciously.
"What is ... which company's software?"
He has worked in this industry for so many years, and has contacted a lot of companies that make such simulation programs, but he has never seen the interface and dynamics simulation can be so delicate ... even perfect. At least as far as he is a professional, he can't think of anything to be picky.
I heard Hou Guang's subconscious inquiries, and Lu Zhou didn't explain in detail, but just said casually: "I asked the code farmer from the Institute of Information Technology to customize it. I will copy it to you after the meeting is over."
The voice of was almost just dropped, and the mobile phone in his pocket shook.
I don't need to guess, I must be Xiao Ai protesting with him.
However, the protest was invalid, and it is impossible for Lu Zhou to disclose its existence at this stage.
I heard Lu Zhou's explanation and Hou Guang opened his mouth.
Although it is not clear which cattle can make such a perfect simulation program, with this stuff, it will definitely help their work.
"Let's not talk about the software ... If you move the engine from the tail to the wing, it will inevitably affect the failure rate. If it is just to improve maneuverability, will there be some losses?"
Lu Zhou shook his head and explained, "It's not just maneuverability. With this design, we can actively reduce the speed of aerospace aircraft to a considerable value in airspace over 30 kilometers, which can not only reduce the return stage Risk, while also directly reducing maintenance costs after a single launch mission. "
"As for the risks you said, 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.
The addition of two electric drive shafts to the aileron means that the structural risk on the wing is increased.
At the same time, in order to ensure 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 materials at the joints, 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 air and space aircraft project.
Xie Houguang frowned and raised his hand to ask: "What about the bidding projects over the space agency and the science and technology bureau?"
"Of course, I will use the Xiangrui to bid," Lu Zhou replied without hesitation. "The new design plan is our goal for the new year. Don't worry, we have enough time to prepare."
After hearing this sentence, Hou Guang was relieved.
Finally, Professor Lu took into consideration the actual situation.
The manned moon landing project is imminent ~ EbookFREE.me ~ The space agency and the Science and Technology Bureau will announce the winning results immediately. At this time, the extracurricular branch is not a suitable choice. But if it is a project for the coming year, it will be no problem.
Lu Zhou and Hou Guang both nodded. It is unlikely that there will be any controversy after the meeting.
PPT continued to show, Lu Zhou briefly talked about the design ideas of this new air-space aircraft.
At this time, the engineer who was taking notes of the meeting pushed his eyes with the pen cover and raised his right hand.
"I have another question."
Lu Zhou generously said, "What's the problem, let's talk."
Engineer: "What's the better name of the new design? Xiangrui No. 2? Or use the letters and numbers first?"
I also use the old name to look less formal.
What's more, the shape of this new aerospace plane has been changed even by its father.
But what is it called ...
Lightning? That thing is an escape hatch.
Meteor? It sounds a little unlucky.
Lu Zhou searched his intestines and scratched his belly for a while, and his heart moved slightly, and he opened his mouth subconsciously.
"... Xia Guang is fine."
