Genius is just the threshold for me!

"Qian Xuesen ballistic missile? Dongfeng-17?"

Lin Dong was surprised when he saw the title. Then he looked down at the specific discussion records and then at Su Ruohua's postscript.

"A new missile project has been initiated at the Northwest Base, requiring the adoption of the Qian Xuesen ballistic scheme that you mentioned on New Year's Eve the year before last."

"Based on what you said back then, I published two papers. Now I'm one of the main project leaders, but we're currently facing insurmountable problems in waverider aerodynamic control above Mach 10 and blackout communication..."

Because Su Ruohua is currently in the Northwest and not at home, and it's not a purely intranet environment, the email did not use a salutation as a precaution.

After reading Su Ruohua's postscript, Lin Dong said with a strange expression, "Godmother, is this a shift from the aerospace field back to ballistic missiles? From sending people into space, back to sending them to their deaths?"

He heard Wang Xingguo and Su Ruohua give a brief overview of Su Ruohua's resume.

Unlike Wang Xingguo, who came to Chengdu Aircraft Industry Group (CAC) right after graduation and rose step by step from an ordinary researcher to become CAC's chief engineer.

After graduating, Su Ruohua joined Project 624. Not long after marrying Wang Xingguo, she was transferred to the Northwest Base in response to the call because she had a double doctorate in engine science and mechanics. She joined Project 204 and participated in the core research and development of the Dongfeng-41's engine and ballistic control...

As the new century began, ballistic missile deterrence systems were gradually improved, reducing the workload of research and development. Meanwhile, the space strategy needed to be accelerated, shifting from ballistic to space-based...

But now, judging from Su Ruohua's words, she has returned to her old profession in aerospace, to the field of ballistics.

"I've actually researched waverider aerodynamic control and blackout communication..."

Lin Dong was amazed by the changes in Su Ruohua's resume. He opened the database of the No. 78 laboratory server and found two data schemes for which papers had not yet been published, which were then encrypted and uploaded to emails.

Because the efficiency of conventional aerodynamic configurations drops sharply when speeds exceed Mach 5, waverider aerodynamic control is an essential requirement for hypersonic aircraft.

Starting with Hot Heat III, there were waverider designs used in Hot Heat IV, with Hot Heat IV using a Mach 10 design.

As for blackout communication, this is a phenomenon that begins to appear at speeds between Mach 8 and 12, and becomes significant above Mach 12.

Essentially, high-speed aerodynamic friction causes excessively high temperatures around the aircraft, resulting in a layer of gaseous plasma sheath that blocks wireless communication signals.

Qian Xuesen's ballistic trajectory involved gliding along the edge of the atmosphere, skipping across water, to evade enemy radar detection and make his path unpredictable and undetectable to the enemy.

This necessitates the use of a waverider design for the missile, and the high speeds (Mach 10 and above) and intense friction with the atmosphere will inevitably lead to communication blackouts.

These two issues were also the core challenges in Qian Xuesen's ballistic missile design.

After all, the essence of Qian Xuesen's ballistic missile lies in the unpredictability of the enemy, not the unpredictability of the launcher.

On the contrary, the launching party must maintain precise control throughout the entire launch and flight process of the missile; otherwise, it would not be the Qian Xuesen ballistic missile, but the Brown ballistic missile of the Eastern superpower.

As for solutions to break through blackout communication, Lin Dong had already explored a series of solutions when he was playing Hot No. 4.

For example, by optimizing the aerodynamic shape, the shock wave distribution and flow field distribution of the aircraft can be changed, thereby reducing the plasma density in the antenna area and reducing communication obstacles.

For example, actively injecting electrophilic substances can absorb free electrons in the plasma that hinder communication, creating a communication window or even a long-term channel.

Another approach involves integrating the magnet and antenna into a single design. Since electrons carrying electrical charges are deflected by a magnetic field, a strong magnetic field with a specific magnetic direction can be created around the antenna, thus establishing a communication window.

According to Lin Dong's calculations, this combination scheme is sufficient to overcome the communication blackout below 16 and can meet the needs of the Dongfeng-17 in the wave-riding gliding phase.

As for speeds above Mach 16, these solutions are no longer sufficient because the plasma sheath of the plasma gas is too dense.

In Lin Dong's plan, this can only be achieved after the completion of the GW constellation project, which will create a global low-Earth orbit satellite network using terahertz satellite communication or laser communication solutions.

As for now.

Without sufficient low-Earth orbit satellite networks, terrestrial terahertz communication solutions suffer severe attenuation in the low-altitude atmosphere, and terrestrial laser communication is blocked by the curvature of the Earth, making it impossible to meet the intercontinental needs of missiles or strategic aircraft.

After dealing with his own emails, Lin Dong logged into Wang Xingguo's email account.

After quickly resolving the issues for the two projects and setting a scheduled reply for the evening, I scrolled down to check the email frequency over the past month and nodded in satisfaction.

"Sharpening your axe won't delay your woodcutting; it seems this training session was quite effective."

"After about half a year of learning, starting last month, the number of problems in the Red Ghost project has decreased by one-third compared to last year, and the progress has been caught up."

"If we continue learning at this pace for another two and a half years, and there are projects like Red Ghost, I won't need to be the chief engineer to maintain an even faster pace."

By then, the industrial upgrading will have begun to show results, and I'll be able to dedicate time to more cutting-edge projects.

Lin Dong sighed inwardly, pulled out a new document, and began, based on his previous experience, to prepare the study outline and materials for Xia Tianqiang and the others for the following week...

Sigrún has taught at the Iceland University of the Arts as a part-time lecturer since and was Dean of the Department of Fine Art from -. In – she held a research position at Reykjavík Art Museum focusing on the role of women in Icelandic art. She studied fine art at the Icelandic College of Arts and Crafts and at Pratt Institute, New York, and holds BA and MA degrees in art history and philosophy from the University of Iceland. Sigrún lives and works in Iceland.

The next morning, Lin Dong didn't sleep in, and Zhang Xiali also cooked breakfast early. After the family finished breakfast, they prepared to go back to their hometown.

"Xiao Dong, have you packed everything? Clothes, phone, watch, computer..." Zhang Xiali called out to Lin Dong, who was still tidying up in the room, after putting the dishes away and washing them.

"I brought everything."

Lin Dong responded, picked up his backpack, and came out. He was taken aback when he saw Lin Weiliang, who had also come out of the house with his car keys. "Dad, are you going back too?"

"It's been a few months since I last saw your grandparents, so I'll go back with you to visit them."

Lin Weiliang said earnestly, "This way, it will be easier for you to handle any issues that arise with the Red Ghost project."

"..."

Lin Dong paused for a moment, then, as if realizing something, asked seriously, "Are the spies still watching Chengfei? Are they still active?"

Last year and the year before, he was busy with the WZ-8 reconnaissance project and the final stages of the J-16D project. When he went back to his hometown during the winter and summer vacations, Lin Weiliang did not accompany him.

But the fact that he suddenly had to go along with them this year made him realize that the spies were still watching Chengdu Aircraft Industry Group and were still active.

This way, Lin Weiliang could go back with him, and given Lin Weiliang's current importance, his security level could be legitimately raised...

"The spies are always keeping an eye on things, but their focus has shifted to me, your godfather, and the biological project... The main reason I'm going back with you is that your grandfather hasn't been feeling well lately, and I want to go back and check on him."

Lin Weiliang gave a brief explanation, then changed the subject and looked at Lin Dong, saying, "Besides, you're going into your third year of junior high, you'll be all grown up... I'll go with you, so we can avoid the situation where your godfather suddenly has a spy as his daughter-in-law."

This "Genius Training Program" codenamed "Hope" was designed to divert the Americans' attention. In order to explain the unusual events at Chengdu Aircraft Industry Group and to reduce the potential risks to Lin Dong, he and Wang Xingguo were honored to be among the rare "geniuses cultivated" in the program.

Although the enemy's attention to Chengfei decreased due to the biological program diverting their focus, their attention to Chengfei and Wang Xingguo increased.

In addition, after experiencing Wang Rui finding a spy girlfriend, Lin Dong is now slowly growing up.

Lin Weiliang was also a little worried that one day, due to the increased attention the enemy paid to him, he might end up with a spy daughter-in-law.

After all, Lin Weiliang really didn't know if his prodigy son could withstand such specialized psychological profiling and customized arrangements.

If you really get targeted and fall for it, it'll be pure luck, and you'll get your base stolen and your dragon stolen... Ugh.

"Dad, you have a daughter-in-law, yet you look down on me like this? And... haven't you seen the scandalous past of Wang Sicong, the son of the former richest man, online?"

"As the son of the richest man in the world, if I really wanted this, would I need spies? I could just wave my hand and there wouldn't be enough people queuing up on Chenghua Avenue."

Lin Dong rolled his eyes speechlessly, then asked with some concern, "Grandpa, how are you feeling? Is anything bothering you?"

According to his memory, in his previous life, the old man survived the pandemic at the age of seventy, experiencing a period of good fortune.

He worked overtime to recover in the 1930s, and was still in good health the day before he made a video call... Now it's 2014, why is he feeling unwell?

"I'm not sure yet, I'll have to go back and check to find out..."

Lin Weiliang shook his head, helped Zhang Xiali carry a suitcase, and the family of three went down to the community parking lot.

beep-

Lin Weiliang pressed the key on his car key, and the black bulletproof Mengshi flashed its lights twice.

The three of them opened the trunk and put their backpacks and suitcases in. Zhang Xiali sat in the passenger seat, while Lin Dong sat alone in the second row.

"Put on your seatbelt..."

Lin Weiliang got into the driver's seat, looked in the rearview mirror, and said to Lin Dong.

"Know."

Lin Dong nodded, pulled over the seatbelt, and obediently fastened it.

The next moment, Lin Weiliang started the car and drove out of the community parking lot. The two security vehicles that were waiting by the roadside immediately connected with him. One car was in front and the other was behind, forming a convoy to go to Lin Dong's hometown.
