199: The best choice

Regardless of whether this information is useful, at least she showed a willingness to actively participate rather than stand by.

Xu Ning said, "The reason I didn't choose this plan is because it requires too many modifications."

Tang Ziwei's smile instantly froze.

Xu Ning explained, "As I said before, we need to base it on existing mature technology.

Although the external appearance of this enlarged plan doesn't change much, it actually involves significant adjustments to the overall structure and even requires a more powerful engine, which goes against our original intention."

Old Wei's expression improved slightly.

He didn't mind his suggestion being rejected; he was just afraid Xu Ning misunderstood his intentions.

Xu Ning continued, "We have all received professional training.

Looking at design drawings shouldn't just stay on the surface but should consider more details."

At this time, Zhao Zhide interjected, cleverly easing the tension: "How could I see any depth? As for the technical aspects, let's listen to Xu Ning.

Tang Ziwei, do you have any other plans?"

After Xu Ning's reminder, Tang Ziwei quickly regained her smile.

She took out some materials again, which were actually just two photos.

"This is an experimental model from the Mikoyan Design Bureau, called the Ye-8.

There isn't much information, but from the photos, it changes the nose intake to a belly intake and adds a pair of canards..."

Xu Ning immediately picked up a photo and studied it carefully.

Looking at the old photo on the table, a strange excitement surged in Xu Ning's heart.

This photo reminded him of a little-known improved version in the J-7 series—the J-7FS.

This fighter attempted to change the traditional nose intake to a chin intake.

This was in order to make space for a larger radar while maintaining the original flight performance.

Although this project failed to continue development due to funding issues and technical bottlenecks, with only one prototype undergoing flight testing, Xu Ning knew its potential value should not be underestimated.

Especially the chin intake technology is crucial for the development of future high-speed aircraft.

In his previous work, there was a hypersonic missile with a similar intake design waiting to be tested.

Considering the time background, this technology was still in its nascent stage.

"Our goal is to comprehensively upgrade the J-7's intake system," Xu Ning explained to his colleagues.

"By introducing a dual-module chin intake, we can not only install larger radar equipment but also optimize aerodynamic performance.

The new design will utilize the space in front of the intake as a pre-compression area, further improving intake efficiency."

Just as he was meticulously planning every detail, a system prompt suddenly appeared in his mind.

After some thought, he decided to invest precious technology points and immediately launch this ambitious research plan.

Almost at the same time as the command was confirmed, a large amount of professional knowledge flooded into Xu Ning's brain like a tide, filling him with confidence about the challenges he was about to face.

This was not just a simple technical upgrade, but a huge leap in personal skills and teamwork ability.

When his colleague Old Wei asked about the reason for the choice, Xu Ning firmly replied, "Although the Ye-8 adopts a more complex canard-delta configuration, our core focus is on the innovation of the intake position.

Placing the intake below the nose retains the advantages of the original fuselage structure and solves the problem of radar installation.

This is the optimal balance point we are pursuing."

Xu Ning picked up a pen and paper and quickly sketched a simple drawing, explaining his design concept as he drew.

"We can achieve optimization by maintaining the original length of the intake and only adjusting the nose section.

Specifically, we can design the radome into a cone shape, making it part of the intake system, thereby pre-compressing the air and improving overall intake efficiency."

The reason he elaborated on these details was not to show off, but because the design scheme provided by the system first required setting a specific cone angle.

Only by determining this point could the optimal intake design be further calculated.

The design results brought about by different cone angles vary greatly, and Xu Ning was not sure which one was most suitable for the J-7 fighter.

Usually, this type of decision relies on rich experience, but for him, who had only been engaged in basic work before, this was undoubtedly a challenge.

To solve this problem, Xu Ning planned to try multiple schemes, gradually filtering out the most ideal choice by simulating and analyzing the performance of the J-7 under each configuration.

Although this task was cumbersome, most of the steps were relatively routine and could be handed over to team members, while he himself focused on solving the core difficulties.

Doing so not only improved work efficiency but also laid the foundation for more efficient use of the system in the future.

"This way, our workload is significantly reduced, and many components can directly use existing designs," Old Wei agreed, clapping his hands forcefully to show support.

"Xu Ning, what's the next step?

We are completely at your disposal."

Just as they were discussing enthusiastically, the research room door opened, and four new faces joined the meeting.

One of them was Xu Ning's roommate, Huang Hongzhang, who asked curiously, "Are you doing research?"

In fact, Huang Hongzhang came specifically to find Xu Ning.

Since starting the research, he had noticed his friend's enthusiasm for fighter design, although he hadn't paid much attention at first.

But after seeing Xu Ning's relaxed and confident look this morning, he couldn't help but feel a bit curious.

He wanted to see what kind of progress Xu Ning had made during this time.

"That's right, this is a task assigned by the higher-ups, and we have to take it seriously," Xu Ning replied while continuing to refine the sketch in his hand, preparing to introduce the upcoming work to his companions.

After all, the research on "Aircraft Design" not only yields high scores but also affects the final grade, especially the defense session, which will be reviewed by several experts from within the academy.

These mentors were usually also the examiners responsible for the interview of theNo test required (exempt from entrance exam) graduate students before.

The time interval from the interview to the start of the research was only about a month.

Therefore, all team members who wanted to pursue further studies knew that this research required their full effort.

After the four team members placed their tools and books on a nearby table, the leader, Huang Hongzhang, walked towards Xu Ning and asked, "What stage are you at now?"

"We just selected the design plan, it's still early," Xu Ning replied without lifting his head.

He didn't care about Huang Hongzhang and didn't regard him as an important person.

The preliminary design work they were discussing did not need to be kept secret, and besides, whether the other party could understand was another question.

However, Tang Ziwei remained highly vigilant towards the approaching Huang Hongzhang.

She quietly moved her feet, cleverly blocking the passage to the table.

Although the passage was narrow, Huang Hongzhang tried several times but couldn't get close.
