"I'll go share this good news with Engineer Zhan later! He's waiting and needs to hand over the H-20 to him as soon as possible so that he can follow up on the new project!" With the J-35 attracting him, Engineer Zhan's heart is about to fly.

He and Engineer Zhan are like the eldest brother, don't laugh at the second brother. They are both equally fascinated, otherwise they would not come over from time to time to check on the progress of Wu Tong and Lu Xiao's collaborative preliminary research and design!

Especially after getting a preliminary understanding of the grand plan set by Lu Xiao and Wu Tong, as well as the feasible technical deductions, he was even more eagerly looking forward to the actual launch of the J-35 project and witnessing its successful implementation.

If those predicted performances can become reality like Wu Tong and Lu Xiao's past achievements, then it will truly be like the roc soaring into the wind, the dragon soaring out of the sea, the sun rising and the moon setting.

Everything is going in a good direction, which is the best thing!

"Wu Tong, next I'll have to work hard on you to optimize the final overall parameters!" Lu Xiao finalized the final design drawing and breathed a sigh of relief.

"And the most important engine!"

In fact, at the beginning, the J-35 was just an expectation in his imagination. Lu Xiao did not expect it to become a reality in a short time.

Even the name of J-35 is just a benchmark against the international level. After the F-35 entered the research and development and test flight, this concept came into being. If foreign countries have the F-35, then they also want to develop the J-35.

The word "J" actually has a powerful and domineering connotation. Annihilation is their most sincere expectation!

At that time, they had not even completely figured out the J-20 and were still working on it day and night.

Fortunately, they met Wu Tong, and never ignored Wu Tong's role and valued Wu Tong's achievements.

With Wu Tong's assistance, the J-20 was perfectly designed, with the help of super fuselage materials and blade materials, and the engine was optimized and improved, making it possible for the J-20 to be quickly formed, put into service, and shock the world.

Immediately afterwards, Wu Tong assisted the J-20 in developing the PL-15 air-to-air missile, which is at the forefront of the world's advanced level. This made the concept of miniaturized air-to-air missiles a reality and gave the J-20 a sharper accumulation of military power.

The technology of the Weilong has been gradually diffracted and assimilated, and Wu Tong has once again assisted in the optimization. Now that the first flight has been successfully completed, the H-20 has once again broken various world records and widened the gap. It is about to enter the production and service sequence.

By solving the generalized NS equations, he achieved a more precise design, surpassing previous limitations and making it his most successful and powerful design. The J-35's initial aerodynamic layout was perfected, but the key to completing the foundation of his design lay with Wu Tong.

At present, the world's leading STOL fighter jet is the F-35B of the United States. However, the F-35B has some shortcomings that cannot be ignored, such as short range, small payload and complex structure.

The complex structure is not scary. They just make technological breakthroughs one by one. If they can come up with a design, they will do everything they can to implement it.

The small payload is a result of their breakthrough in scientific research on miniaturized and high-powered air-to-air missiles, as well as the significant reduction in the weight of the fuselage made of various super materials, which all contribute to the expansion of the payload.

Therefore, the most direct problem they have to face, and also the most core problem, is the short range.

As we all know, the range of a fighter jet, that is, the endurance time, is mainly determined by the amount of fuel, but during the flight, it is also related to the fighter's cruising altitude, the amount of wind at the altitude, and the cruising speed...

The problem of the short range of the Stovl fighter, in addition to the above factors, is mainly due to the fact that during the short-distance and vertical take-off and landing phases of the aircraft, the engine must run at full power to achieve super maneuverability.

Such operations will naturally consume a lot of fuel, resulting in the fighter jet having a full tank before taking off. However, after a successful takeoff, the actual amount of fuel available is only one-third at most. The range is naturally greatly reduced under the normal operation process.

Even with the current superior performance of the WS-15S, such consumption is not enough. The original design of the WS-15S was not designed around the STOVL fighter.

This is a key issue that must be resolved.

Wu Tong, Lu Xiao and Feng Yuanyang held a symposium. As a backbone of young scientific researchers, Feng Yuanyang is knowledgeable and experienced, so he is naturally familiar with the advantages and disadvantages of STOVL.

"To solve the problem of short range, there are only two ways in front of us. The first, the simplest and most brutal method is to increase the fuel tank reserves, or the quantity!" Feng Yuanyang spread his hands and said very intuitively. They discussed the problem and found the most feasible solution. Naturally, there was no need to hide anything and just say whatever they wanted.

"There are many options for this method, such as adding a fuel tank to the vertical tail, designing a conformal fuel tank, and using spin-formed ceramic thin-walled fuel tank technology..."

"These solutions can be used individually or in combination, but if we increase the amount of fuel carried, we will inevitably have to make trade-offs in the overall performance of the fighter!"

For Lu Xiao, unless it is absolutely necessary, sacrificing the overall performance of the fighter to increase the fuel carrying capacity and increase the range of carrier-based fighters is putting the cart before the horse.

"This is only a last resort. What we're pursuing is the ultimate combat capability of the fighter jets. We're striving for a perfect solution!"

"Since it's not the best option, let's put it aside for now. The best solution is to start with engine optimization. We need to make the engine work in the best condition under various flight conditions, maximize fuel conservation and achieve higher performance!" Wu Tong wrote and drew on the notebook, recording their needs for engine optimization.

"Leave it to me next. Give me some time and I will give you a complete plan as soon as possible!" Wu Tong asked directly. Brother Lu has completed the overall design. Now it is necessary to divide the work into sections to gradually implement the technology and optimize the overall parameters. The engine section is within her area of expertise, so she will be responsible for researching it.

"Okay, I'll leave the most core areas to you, Wu Tong! Weapon system, avionics system, radar system... Professor Feng and I will verify the technical feasibility of these areas one by one!" Lu Xiao and Feng Yuanyang nodded immediately. They were absolutely convinced of Wu Tong's abilities.

Back at her desk, Wu Tong reviewed the overall design of the J-35. She worked tirelessly on deducing and calculating, making the parameters more precise and perfect. At the same time, she was multitasking, thinking about the engine as well.

Optimizing the engine was already an important topic that she had already included in the process. The current discussion further highlighted the importance of this research topic. She had to find a breakthrough direction as soon as possible to provide a sufficient power foundation for the J-35.
