204: Comprehensive upgrade

In such settings, an eye-catching rendering often leaves a deep first impression.

Finally, the day of the research and development defense arrived. When Xu Ning arrived at the laboratory, he found it already packed with people, so he had to squeeze into the back row by the window with his teammates.

For these group members, even though they had mastered most of the professional knowledge, independently completing a complete aircraft development plan was still a significant challenge.

In this assignment, the focus of the grading was usually on whether each group's development ideas and process were reasonable.

After all, developing a real "airplane" is quite difficult, and few groups can achieve it.

As expected, the works of the previous few groups were relatively traditional, mostly small remote-controlled model airplanes made according to examples in textbooks.

Although such works were unlikely to receive high scores, it was also difficult to make serious mistakes. The judges' questions were also relatively standard, and each group's presentation only took about 15 minutes.

It wasn't until the group led by Huang Hongzhang took the stage that the atmosphere in the classroom changed. Huang Hongzhang gently placed a thick stack of documents on the table in front of the judges.

"A seaplane? Quite interesting." Judge Liu Yuanbo showed a hint of interest, picking up the glasses on the table and putting them on.

The other judges immediately perked up as well.

Another team member placed the development drawings under the projector.

Although the image was not very clear, everyone could still see that it was the development of an airplane with two pontoons.

This immediately caused a buzz of discussion among the group members in the back row.

"Look at that, it's a seaplane!"

"And it looks like it can carry people."

"That's right, look at the size written on it, it's 10 meters long! Huang Hongzhang is truly daring to try."

"Remember someone said they were going to make a fighter jet?"

"Probably just talk. It's already very difficult to develop an airplane that can carry people, as for a fighter jet... that's simply a pipe dream."

Standing on the podium, Huang Hongzhang was silent for a moment. Although he couldn't clearly hear the specific discussions of the group members in the back, he could feel their surprise and admiration.

At this moment, he felt incredibly proud.

"Good morning, esteemed judges and mentors. Our group is presenting the development of a 2.5-ton seaplane capable of accommodating six passengers," Huang Hongzhang began his speech.

"Our development plan adopts a simple and reliable twin-pontoon structure, aimed at ensuring..."

In the quiet laboratory, Huang Hongzhang slowly walked onto the podium and began his explanation of the seaplane pontoon development.

He first introduced the unique shape of the pontoons and how it affects their movement characteristics in water.

"Imagine," he said, "like an elegant swan gently touching the water's surface, the pontoon's development allows the airplane to glide smoothly while reducing drag."

Next, Huang Hongzhang shared a detailed set of calculation methods used to determine the optimal size and shape of the pontoons.

"If you want to know more details," he smiled, pointing to specific sections in the report, "everything is right here."

He also showed internal structure diagrams of the pontoons, explaining how they withstand external pressure, and directed the audience to consult additional resources to understand the mathematical principles behind them.

Although the seaplane developed by Huang Hongzhang was not outstanding in appearance, his attention to every detail was impressive.

Whether it was material selection or strength analysis, every step was carefully considered.

This effort was recognized by everyone present; when he finished his speech, thunderous applause erupted throughout the room.

"Hey, Ning Ge, what are they so excited about? Our development is clearly better," Tang Ziwei whispered.

However, Xu Ning expressed a different opinion: "It's really great to be able to complete such a complex development in such a short time. Especially the understanding of the twin-pontoon section, it has reached a professional level."

Then it was Xu Ning's group's turn to present their work, a new type of fighter jet based on an improved J-7. As Xu Ning walked towards the podium, he noticed the look in Huang Hongzhang's eyes carrying a hint of challenge.

But at this moment, the most important thing was to focus on his own project. As the judges took the relatively thin development document, Huang Hongzhang secretly gloated, thinking victory was within reach.

However, the real competition had just begun.

Xu Ning stood on the podium, his gaze firm, and said: "Mentors, group members, our team this time is presenting a bold innovation of the J-7 fighter jet."

As soon as he finished speaking, Zhao Zhide quickly projected a colorful rendering onto the large screen, immediately attracting everyone's attention.

"Wow, are they really developing a new fighter jet?"

"Is this even moresharp (powerful/impressive) than Huang Hongzhang's? Did they just change the outer shell?"

"Don't joke, the J-7 wouldn't look like this!"

Facing the doubts from the audience, Xu Ning calmly began his introduction: "As an important force of China's Air Force, the J-7 has issues with insufficient all-weather combat capability and lack of beyond-visual-range strike capabilities. For this, we have conducted a comprehensive upgrade."

"First, we changed the traditional nose intake to a chin intake design, which not only allows for larger radar systems but also optimizes the overall aerodynamic characteristics."

He continued to explain: "Through an integrated design, including the intake and the forward fuselage section, we ensured good coordination with the engine."

"This innovation has been verified through simulation using professional software, proving its superior performance. For specific technical details, please refer to the relevant chapters in the report."

As Xu Ning's explanation went deeper but remained easy to understand, the judges and mentors who had initially been listening quietly gradually showed strong interest. They began to read the materials in their hands seriously and occasionally exchanged opinions.

Some mentors even took out notebooks and started taking notes, which was an almost unbelievable sight for most of the group members.

At this moment, everyone's focus was no longer limited to the content of the speech itself, but was deeply shaken by such a scene: a young student was presenting his unique ideas to several senior experts, and the latter were showing unprecedented respect.

Huang Hongzhang was initially full of confidence, but the scene before him left him speechless.

It turned out that the reason the other party's development description was half as thick as theirs was because many steps did not need detailed recording but relied on experience.

Xu Ning held a carefully drawn half-model diagram and with just two concise sentences made several judges nod repeatedly.

Although Huang Hongzhang was completely confused, the judges clearly agreed with Xu Ning's ideas.

"The newly designed intake duct, under different conditions, such as at a speed of Mach 1.5, achieved a total pressure recovery coefficient of over 0.95; and at Mach 0.8, it exceeded 0.968, while maintaining good airflow quality."

Next, Xu Ning shared exciting news: "The new design improved the aircraft's performance by 3% - 8% at subsonic speeds, and even exceeded 10% at supersonic speeds."
