Xueba: I study hard in the wasteland world

Su Yu guessed right. His graduation defense turned into an application report meeting for a project.

His "graduation defense" was attended not only by academicians, but also by many generals.

Su Yu has passed the stage where he would be nervous when standing on the podium. Standing on the podium, he looked normal, straightened the microphone, and said:

"Good morning, teachers and leaders. Next, I will give you a brief report on my research opinions on self-powered jet drones."

"This is my Ph.D. graduation defense. I hope the leaders will not make it too difficult for me, a junior!"

Then, Su Yu made a joke and his PPT started to show.

The content of Su Yu's report is very simple, which is a PPT explanation of more than ten pages. The following communication and question sessions are the focus of this meeting.

"Hello, Director Su, my question is about the stability of your drone!"

After Su Yu finished his report, an old academician in the audience asked a question about stability. Su Yu nodded and listened carefully to the old academician's question.

Then, Su Yu began to find the relevant PPT page and began to introduce: "Due to the inherent nonlinear characteristics of the aerodynamic characteristics, as well as the nonlinear and cross-coupling characteristics brought by the aircraft's six degrees of freedom, the movement of the aircraft is modified. Detailed analysis is very complex.

However, for small perturbation cases, it can be assumed that the motion is linear and the impact of cross-coupling is small, thereby ignoring complex nonlinear factors,"

Su Yu on the stage answered the question seriously, and the old academician who asked the question nodded, indicating that there was no problem.

Then, an air force general with thick eyebrows and a murderous look asked: "Hello, Director Su, my question is about drone operations."

After the old general finished asking questions, Su Yu picked up the whiteboard marker, briefly drew the tactical movements of a fighter plane on the whiteboard, and explained:

"Use an infrared guided combat missile with a vertical axis of 40 degrees and attack about 10 degrees from the front. The hit probability is as high as 71%. However, if it is 20 degrees away, the hit probability is only 52.2%, and the hit probability from the front and side is only 52.2%. 19.4%”

Although Su Yu is not a professional fighter pilot, Su Yu's profession requires that he must also be proficient in actual combat theory.

After hearing Su Yu's answer, the Air Force general nodded with satisfaction. Su Yu's air combat tactics theory was already better than that of many air combat experts.

Su Yu’s “graduation defense” lasted for a long time. After the question and answer session, Su Yu began to summarize:

"In this jet drone project, my focus is to solve the endurance problem."

"right"

Su Yu, who was standing on the lecture topic, nodded to herself and continued to speak out the core content of the report: "I just want to apply self-generating materials to jet drones!"

After Su Yu said this, the venue became agitated. The long-awaited "dinner" finally arrived.

Now the military has begun large-scale purchases of self-generated drones from the Taotie UAV Company. This self-powered Taotie drone is already changing the country's military thinking.

But the Taotie UAV is a very small aspect after all, and if Su Yu’s current project can successfully use self-generating materials on jet UAVs, can it also be successfully used on manned fighter aircraft?

Imagine that the Zhan-20 that takes off can generate its own power energy. What a breakthrough this is!

The naval generals in the venue were even more excited. China actually has a rich technological accumulation in vertical fighter aircraft.

However, there have always been great weaknesses in the number of orders and range of vertical take-off and landing carrier-based aircraft.

Without the power brought by ski-jump take-off, this means that for fighters of the same tonnage, vertical take-off and landing carrier-based aircraft have a shorter range and less bomb load than ski-jump carrier-based aircraft.

Therefore, the vertical take-off and landing carrier-based aircraft looks very cool, but in fact, its actual combat effectiveness is very useless.

And if the fighter aircraft can generate electricity on its own during flight, this means that the vertical take-off and landing carrier-based aircraft can reduce the amount of fuel, and then the "bomb load capacity" and "range" problems it faces will be solved.

After listening to Su Yu's words, the Navy's eyes even saw the vertical take-off and landing fighter jets on the 10,000-ton cruise ship!

After listening to Su Yu's words, the air force and navy present swallowed a mouthful of saliva greedily and excitedly, as if they had seen a treasure.

But it was the "big brother" of the army who spoke first. After Su Yu finished speaking, an army general said: "In other words, if your project goes well, it means that self-generating materials can even be used in missiles and artillery shells. superior?"

Su Yu was stunned. His original goal was a self-generated jet unmanned fighter aircraft that could cooperate with manned fighters. It really didn't reach missiles and artillery shells!

But after the general asked, Su Yu thought for a moment and said with a bit of surprise: "It seems to be true! If this jet drone project goes well, it seems that this self-generating material can be used in all military fields, even the deep sea Submarines have also begun to use the energy of water flowing through the submarine to generate electricity."

After Su Yu finished speaking, the entire conference room fell into an oppressive silence.

Several generals from the General Assembly Department exchanged glances and said to Su Yu: "Director Su, please go to the lounge and wait for a while. Your report is too much beyond our expectations. We need to exchange opinions."

"OK!"

Su Yu nodded, he happened to be tired too.

"Xiao Jiang, take Director Su to the lounge!"

The old general gave instructions to the major officer Jiang Changmao who came to pick up Su Yu.

"yes!"

Jiang Changmao stood up straightly, and then respectfully said to Su Yu: "Chief, please come this way!"

The experts and professors sitting in the back row of the meeting looked at the named major officer Jiang Changmao with envy. Everyone could see that the military wanted this young major to study with Su Yu.

And if he can study with Su Yu and participate in projects with Su Yu, this major officer has a bright future!

"Huh~"

Sitting on the sofa in the lounge, Su Yu raised her head and breathed a sigh of relief. The graduation defense of this aerospace major was much more difficult than Su Yu's graduation defense of materials science, mathematics and physics.

Su Yu's graduation defenses for materials science, mathematics and physics have ended. The graduation defenses for these three majors are very simple. It is a defense, but it is better to say that it is a discussion between Su Yu and the authoritative scholars of these three majors in China. meeting.

"Chief, please drink water!"

Jiang Changmao respectfully handed Su Yu a cup of brewed tea.

Su Yu was really thirsty. She took a sip of tea and said to the nervous major officer with a smile: "Brother, don't be so nervous. We are about the same age. You, the commander, call me. I’m so embarrassed!”

Su Yu was really a little embarrassed, and after Su Yu finished speaking, the young Jiang Changmao scratched his head even more embarrassedly.

In Jiang Changmao's impression, Su Yu was very scary, but when he actually met Su Yu, he felt that Su Yu was still very kind, at least not as serious and scary as he imagined.
