Chen Nian let out a long breath. He knew that mastering the theory and technology did not mean that it would be easy to create things, but at least he had taken an important step in the "solution".

Even if Chen Nian comes up with technology now, it will be difficult to actively promote the progress of the project.

After all, scientific research is a process of exploration and trial and error.

Yang Wei looked at the latest submitted materials with a solemn expression.

The first is to expand the fuel tank capacity.

"They are all experienced experts, and some even serve in the Army and Air Force."

So, if he does not have to focus on these two projects, his best choice is to continue to strengthen the J-20B project.

That young man. He is a ruthless man who can blaze new trails on his own.

Looking at their eyes, Yang Wei gritted his teeth and said:

The main reason for this problem is that during the take-off and landing stages of the aircraft, the engine operating at full power will consume a large amount of fuel. As a result, even if the aircraft takes off with a full tank of fuel, only one-third of the actual amount of fuel will be available after it takes off.

"Then the meaning of this plane will be lost at least 80%!"

The pillows were changed and the mattress was simply changed.

According to the information Chen Nian had in his previous life, the fuel efficiency of some types of advanced variable-cycle engines can even be more than twice that of ordinary engines.

So, the second way is relatively more advanced.

Since I bought a four-piece set, I also need to change the pillows to comfortable ones.

That is the pride of being an aircraft designer.

In other words, if the same tank of fuel can fly 1,000 kilometers using a turbofan engine, then it is possible to fly 2,000 kilometers or more using a variable-cycle engine.

Then solve it!

Judging from the situation of the previous F-35B, its main shortcomings are nothing more than a few:

It has a short range, a small bomb load, and a complex structure.

A thought quickly flashed through his mind:

"Start parsing!"

If this path is really wrong, then let him decide life and death.

"Especially when our territorial waters are so large, such a voyage is really not enough."

"Of course, we cannot rule out that they deliberately released false information to lure us to follow up."

Another voice interrupted him and asked in a depressed tone:

"Because frankly, we don't know either."

“But will there really be any results if we keep doing it?”

Therefore, solving the problem of variable cycle engines is equivalent to solving the problem of insufficient range of STOVL aircraft.

"Are they really not working on the F-35B anymore?"

In addition, doesn’t it mean that the bomb load is insufficient? Wouldn’t it be enough to increase the power of the single-shot missile?

"For example, the question of whether STOVL fighter jets are useful, in fact, the core is the range. So, is there any way we can solve the range problem?"

According to the current progress of each project displayed on the "Task Manager", whether it is the Deep Blue 16 project or the high-speed rail project, they are all in the stage of digesting the early results. It is unrealistic for them to continue to accept new technologies.

In desperation, he had to postpone the analysis of the conformal fuel tank, saving 0.2 source points for PL-17.

Looking at the dazzling "0.05" source number, Chen Nian felt regretful and relieved at the same time.

After just one operation, the nearly 5 source points that Chen Nian saved during this period were completely spent, and it was not even enough.

After another long period of silence, the voice sounded again from the corner of the conference room.

Both of these things are available, lightweight materials are also arranged, and structural materials cannot be careless.

Although the core principle of the variable cycle engine is simply to adjust the size of the three ducts, to do this under extreme high temperatures, high pressures, and high speeds, it is also necessary to ensure the stability of the engine structure, which has a great impact on materials and processes.

The requirements are still improved compared to F119.

Everyone wants to do something new, and they all want to make a "Killer product" to completely throw off the Lockheed Martin who has been riding on their head, and then chase after the 601 Institute that has already built the J-22.

But, would he say that?

It seems that I have never heard the word "no" from his mouth.

A few minutes later, Chen Nian walked into the conference room.

To explain in the most intuitive language, a traditional turbofan engine must make a trade-off between high thrust and high efficiency when designing. It cannot have both, nor can it be switched at any time, but a variable cycle engine can.

For a moment, sighs could be heard in the conference room.

This is the simplest and crudest method, but there are actually many different solutions for implementation.

If even he says no, forget it.

The STOVL is not only for the aircraft itself, but also for the accumulation of technology produced in it, which will also provide a lot of assistance for future research and development work.

——

This is their original idea.

If you are pursuing extreme combat effectiveness, the first path is not the best choice.

"However, since the discussion has reached this point, let's just talk about it."

Speaking of which, the system gave a price of 2.4 points, which is actually considered a discount.

Chen Nian hesitated for a moment, and finally made up his mind.

"We can't just look at the problem itself, we should take a long-term view and look at it in an extended way."

[XA-100 adaptive variable cycle engine]

"After all, if we withdraw at this time, all the resources invested in the early stage will be wasted."

Before he finished speaking, someone interrupted him directly.

As soon as these words were spoken, everyone who had their own thoughts all looked at Yang Wei, as if waiting for him to make the final decision.

That is, a variable cycle engine.

"We simply won't be able to solve these problems in a short period of time."

"How to do a variable cycle engine? The aerodynamic layout optimization has reached its limit, how can we still optimize it? The fuel tank. Unless there are new materials, there is no need to discuss it at all."

"It can take off by taxiing and land vertically."

"This information has not yet been 100% confirmed, but judging from all aspects of information, the possibility is still relatively high."

But obviously, this thing is not as simple as he thought.

"I already understand the situation."

"Isn't it just a variable cycle engine? Here, the core technical principles are here, do you want to see it?"

"I also have technical documents here for conformal fuel tanks, spin-formed ceramic thin-walled fuel tanks, the new over-the-horizon air-to-air missile PL-17, lightweight structural connection materials, and lightweight titanium-aluminum alloy TC4-2 materials."

"Together, these things should be enough for us to continue this project, right?"
Chapter completed!
