Chapter 293 Question
"I will share this good news with Engineer Zhan later! He is waiting 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 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 really be like the roc soaring into the wind, the dragon flying out to 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 standards. After the F-35 entered the research and development and test flight, this concept came into being. Since foreign countries have the F-35, they also want to develop the J-35.
The word J actually has a powerful and domineering connotation: annihilation! This is their most sincere expectation!
At that time, they actually hadn't even completely figured out the J-20 and were still working on it day and night.
Fortunately, they met Wu Tong, 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 a J-20 that was quickly formed, put into service, and shocked the world.
Soon after, Wu Tong assisted the J-20 in developing the PL-15 air-to-air missile, which is at the world's advanced level. This turned the concept of miniaturized air-to-air missile into reality and gave the J-20 a sharper accumulation of military power.
The technology of Weilong has been gradually diffracted and assimilated, and Wu Tong has once again helped to optimize it. Now that its maiden flight has been successfully completed and various world records have been broken again, the H-20, which has widened the gap, is about to enter the production and service sequence.
With the help of the general solution of the NS equation, he had a more precise design, breaking through the previous limits, and it can be said to be his most successful and powerful design. The preliminary aerodynamic layout design of the J-35 was perfected, and the most important key to completing the foundation of his design was still Wu Tong.
At present, the world's leading STOL fighter 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 have made technological breakthroughs one after another. Once they can come up with a design, they will do everything they can to implement it.
The small payload is helped by their scientific research progress in making air-to-air missiles miniaturized and powerful, as well as the use of various super materials to significantly reduce the weight of the fuselage.
Therefore, the most direct and most core problem they have to face 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 jet's cruising altitude, the amount of wind at the altitude, and the cruising speed...
In addition to the above factors, the problem of the short range of the Stovl fighter is mainly that during the short-distance and vertical take-off and landing phase of the aircraft, the engine must be running at full power to achieve super maneuverability.
Such operations will naturally consume a large amount of fuel, resulting in the fighter jet's fuel tank being full before taking off. However, after a successful takeoff, the actual available fuel amount is only one-third at most. The range is naturally greatly reduced under the course of normal operations.
Such consumption is beyond the capability of the WS-15S. The WS-15S was not originally designed for 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 well-informed and 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-wall fuel tank technology..."
"These solutions can be used individually or in combination, but if we adopt the method of increasing the amount of fuel carried, it is inevitable that we will 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 jet to increase the fuel carrying capacity and increase the range of carrier-based fighter jets is putting the cart before the horse.
"This is only the last resort. What we are pursuing is the ultimate combat capability of the fighter jets. We are striving for a perfect solution!"
"Since it is not the best choice, let's put it aside for now. The best solution is to start with engine optimization. We need to make the engine work at its best under various flight conditions and maximize fuel economy to achieve higher performance!" Wu Tong wrote and drew on the notebook, recording their needs for engine optimization.
"Next, leave it to me. 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 design into sections to gradually implement the technology and optimize the overall parameters. The engine section is within her 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 non-stop on calculations to make the parameters more precise and perfect. At the same time, she was also thinking about the engine.
Optimizing the engine was an important topic that she had already included in her progress. The current discussion has further highlighted the importance of this research topic. She must find a breakthrough direction as soon as possible to provide a sufficient power foundation for the J-35.
