Genius is just the threshold for me!

With Wang Rui and Feng Mei's affairs settled, the rest of the schedule became much smoother.

The HMS Lohengrin stayed in the Xisha Islands for a few days. Lin Dong and his group went diving, fishing, sunbathing, and explored the mysterious Sansha Administrative Region...

On the 8th, they returned to base, and on the 9th at noon, the group left Haikou and headed to the launch center in Longlou Town, Wenchang.

In less than two hours, the convoy arrived at the launch center. Everyone got out of the cars, and Su Ruohua came over.

"Arui, Xiaodong, Qingling, Xiaomei..."

"mom."

Wang Rui called out, and Feng Mei, who was standing next to him, was less outgoing than when they first met, and instead became more reserved, calling him "Auntie."

"Why!"

Su Ruohua immediately responded happily.

Lin Dong stepped forward and asked, "Godmother, has the launch time been set?"

"It's confirmed."

Su Ruohua said with a smile, "It will be even more spectacular tonight at 19:23 PM."

"With Godmother so confident, it seems the Long March 5 launch will go very smoothly," Lin Dong said with a smile.

"You little rascal, when has your godmother ever lacked confidence?"

Su Ruohua replied irritably, then invited everyone into the launch center, leading them to the viewing area, the canteen, the rest area, and the free activity area for a stroll.

Back in the rest area, Wang Rui grabbed Lin Dong and said, "Come on, Xiao Dong, my mom wants me to go over there. Can you help me out?"

"Brother Rui, you don't have to be so cowardly," Lin Dong said with a smile as he stood up.

"Dongdong, give me your phone, I want to see the photos you've taken these past few days..." Xu Qingling saw Lin Dong about to go over and immediately reached out for Lin Dong's everyday phone.

"Could you charge my phone while you're at it?"

Lin Dong handed his phone to Xu Qingling and went with Wang Rui to a private rest room for Su Ruohua.

Because Su Ruohua, as a technical expert, arrived a few days in advance to provide technical support for the Long March 5 launch mission, she naturally has a dedicated space here at the center.

After walking for a few minutes, Wang Rui and Lin Dong arrived at Su Ruohua's private room.

This is a two-bedroom suite with a meeting room and a small living room. When the two people entered, the anti-eavesdropping device in the suite was already turned on.

"Arui is reading in the living room outside. Turn off your phone and put it in the box."

Upon seeing the two of them, Su Ruohua pointed to a lead-lined soundproof box in the room, indicating that Wang Rui should put his phone inside.

"oh."

Wang Rui had a keen understanding of how to use someone as a tool; he took out his own phone, put it inside, and then closed the box to block out all signals.

"Xiao Dong."

Su Ruohua entered the meeting room and poured Lin Dong a glass of water: "Have you read that email?"

"I've seen it."

Lin Dong knew that Su Ruohua did not bring the decryption codebook and did not know the contents of the ciphertext in the email. He took the water glass and said, "1.4 or more, Qian Xuesen trajectory, multiple warheads, 3 to 15 minutes response time, control scheme demonstration."

"...I knew it was this."

Su Ruohua breathed a sigh of relief: "When the Dongfeng-17 was completed, the preliminary feasibility study for this type of intercontinental ballistic missile had already begun."

"It's just that the situation in the south was more important at the time, and there weren't enough resources to mobilize. Now that things have calmed down in the south, there are resources available..."

Although the Dongfeng-61 is a strategic cornerstone, it is not necessarily the first project to be launched.

address:\\\\\\\\\\\\.\\\\\\

With the Dongfeng-41 missile already providing strategic deterrence and the probability of global nuclear war relatively low, the southern issues and the deployment of naval vessels to the open sea are clearly more urgent.

Now that the south has been pacified and the strategic focus has shifted, this missile project, which further enhances the core strategic deterrence, has naturally been launched.

"1.4 kilometers or more, Qian Xuesen trajectory, 10-minute response time... This is very difficult." Su Ruohua thought seriously for a while, her expression becoming more solemn: "Aerodynamic layout and aerodynamic drag, control and guidance scheme, and engine scheme."

Su Ruohua immediately pointed out the core difficulties of the project.

Unlike previous intercontinental ballistic missiles that followed a parabolic trajectory through space.

Because Qian Xuesen's trajectory requires gliding through a critical space, there will inevitably be a continuous consumption of aerodynamic drag.

In addition to the extreme control scheme, the key is to ensure a range of more than 10,000 kilometers and a terminal speed of more than Mach 20 under continuous drag consumption.

This is related to the missile's engine and the aerodynamic drag design of the warhead.

"I haven't studied solid fuel engines much, but if you have enough data to provide a solution, I can help with the pneumatic solution, and I also have some ideas about the control and guidance system."

Lin Dong gave a brief explanation.

He's only used solid-fuel engines on anti-ship drones so far.

But he doesn't have much experience with airdropping drones that only last a few seconds, or launching intercontinental solid-fuel engines that can travel 10,000 or 20,000 kilometers.

Of course, if there is enough data, it wouldn't be a problem to have him redesign one.

After all, it's a technology that's been around for over half a century. It doesn't involve any uncharted technological territory; it's just a matter of putting in some effort.

"Control and guidance scheme..." Su Ruohua's eyes lit up: "Xiao Dong, you have an idea?"

"Conventional inertial guidance for BeiDou satellite navigation starlight correction."

Lin Dong nodded and said with a smile, "Of course, this level of accuracy still cannot be guaranteed. We will introduce A technology in the mid-course phase to allow the warhead to autonomously eliminate flight errors and intelligently optimize its penetration path."

"Mid-section control in section A?"

Su Ruohua frowned: "Is this okay?"

Su Ruohua has also studied A technology in recent years and knows that it is a future development direction.

But I still feel a little uneasy about letting such new technology be involved in such strategic deterrence missiles.

"Godmother, it's not about letting A control us, it's about letting A correct us."

Lin Dong smiled and explained, "Qian Xuesen's ballistic trajectory is very complex, and the amount of data that can cause external interference is enormous. A is quite good at this."

The A algorithm is introduced to perform ballistic correction in the mid-course phase.

This was originally a solution adopted by the Dongfeng-61 ten years later, and this time he was essentially learning from his past experience.

The application of A to big data processing and its contribution to scientific research is an undeniable trend. Ten years later, A may even be able to solve equation N.

Now that A has been developed so many years ahead of schedule, although it is not yet at the level of ten years later, it is definitely not a problem to meet the requirements of Dongfeng-61.

"If it works, then it's fine."

Su Ruohua still trusted Lin Dong, and said seriously, "Xiao Dong, when we get back I will assist in this matter. The aerospace base project will be entrusted to you."

"Academician Ma Weiming has solved several technical problems these past few days. The current control scheme should be fine, but I haven't verified it yet, and the flight linkage control scheme is still not complete..."

"no problem."

Lin Dong nodded: "Godmother, as long as you don't go to the Northwest, just check your emails every day at Chengdu Aircraft Industry Group to keep track of the progress."

As one of the core experts in the Northwest, Su Ruohua would certainly have assisted and participated in the Dongfeng-61 project.

But as long as he doesn't go to the Northwest and stays at Chengdu Aircraft Industry Group, Lin Dong doesn't mind.

After all, he only wanted Su Ruohua's name; he didn't need Su Ruohua to actually participate in anything.

"No need for that. I'm not involved in frontline testing and R&D now. I just provide technical support. It's similar to how the China Aerospace Science and Technology Corporation has offices in the capital. I can work in Chengdu and coordinate with the Northwest. I can just go on a business trip there every month or two to check on things."

Su Ruohua gently shook her head, then picked up the computer and opened her email: "You've been looking at the project's progress, right? If you're not familiar with the team below, let me explain..."

"I've seen it; taking over shouldn't be a big problem now."

Lin Dong took Su Ruohua's notebook, glanced at the latest emails, especially the reply from Academician Ma Weiming, and immediately understood the situation.

"Today is the 9th, everyone's at work..."

Lin Dong pondered Su Ruohua's writing style and tone of voice, then opened an email, glanced at it, and opened the reply input box in less than two seconds.

[Su Ruohua]: Engineer Huang, we haven't had much time to get to know each other at the aerospace base, so we need to speed things up on the project...

Referring to the latest high-performance motor solutions, the team from the company collaborated with Didi to improve the high power density generator, aiming to achieve a power density of 10 to 20 kWh/k.

If you have any questions, please refer to the thesis numbered J768B, as well as the learning materials that Engineer Wang assigned to you last September...

[Su Ruohua]: Engineer Xia, the team has been working together quite well recently. The core challenge of the space cargo spacecraft is indeed docking. Controlling the center of mass offset to the millimeter level and the speed accuracy to the centimeter level per second is also acceptable. Otherwise, with the massive mass of the spacecraft and the space station, any misalignment or collision would be a space disaster...

However, the preliminary solution you provided is barely adequate for the hardware control system of 28 engines, but it is seriously inadequate at the software algorithm level.

Please refer to relevant papers such as J8H768 and BK6278, as well as the following databases, to relearn how to design algorithm systems in this area. Do not submit such inferior solutions.

[Su Ruohua]: Engineer Guo, the current solution for the electric pump's seals and bearings is sufficient for use, but it needs to be improved further by adding some safety redundancy to prevent propellant leakage from the pump body, which could cause the rocket to explode upon takeoff.

Our rockets are currently launching from Xichang. There are residential areas nearby, so we must ensure adequate safety redundancy. For specific improvement ideas, you can review the learning materials that Engineer Wang assigned to you in March of this year…

[Su Ruohua]: Engineer Xu, the project needs to be accelerated. The current 3D additive printing engineering solution is no longer sufficient for the upcoming medium-sized rocket project. Please expedite the technological advancement and improvement... For specific improvement ideas, please refer to the learning materials that Engineer Wang assigned to you in April and May of this year...

"..."

Su Ruohua stood to the side, watching Lin Dong quickly provide the next task and solution in just a few seconds after thinking through each email. In no time, more than a dozen emails had been sent out.

With a snap.

The entire project progressed much faster.

Moreover, each email accurately provided the corresponding academic paper and learning materials. At this moment, Su Ruohua was completely dumbfounded.

Although she already knew from Wang Xingguo about Lin Dong taking over the project, she still felt an overwhelming pressure when it was her turn to face it.

...No wonder they didn't take over the space base at the beginning; they wanted to wait until the team was familiar with and integrated before taking over.

If Lin Dong had taken over the project from the beginning, the entire aerospace base would have been dismantled due to this project development and management approach.

"alright."

After replying to more than twenty emails from the core R&D team of the aerospace base, Lin Dong glanced at them to make sure he hadn't missed anything and then closed his notebook.

"At this pace, it should be completed by the end of the month. If we can get familiar with the production process while simultaneously producing, the first rocket product can be rolled off the production line in December... Well, commercial spaceflight needs to be commercially operated, so we'll also shoot a test flight video and try something new."

"The foreigners, seeing the PA Falcon rocket, immediately called our rockets rubbish and accused us of stealing their technology."

Su Ruohua didn't reply, but instead checked the time.

When she saw that Lin Dong had been there for less than twenty minutes, most of which was spent downloading attachments and typing, she suddenly felt a little uneasy.

"...Xiao Dong, it's your decision."

Su Ruohua sighed silently.

Today she witnessed firsthand just how perverted Wang Xingguo was.

I've decided that once the Long March 5 launch is complete, I must go home and learn from Lao Wang how to brag and fool people... Otherwise, if I run into some acquaintances in the future and they ask about the progress of this space project, it will be really hard to answer.
