Chapter 144 Foundation
Yang Wei reported the relevant data concisely and powerfully, and breathed a sigh of relief!
Now, Lu Xiao can no longer be so mean and say that their engine is sick!
"I'll send you the detailed test data later. We've completed the engine mission. It's up to you to get the Chinese Eagle off the ground!"
In addition to the engine section, the fighter's radar, flight control, speed, weapons, etc. are also the most important sections. Now in the engine section, they have made super-superior supplements and can provide strong and sufficient power for these sections.
Through the phone line, Lu Xiao could feel the strong pride of the rise of the person on the other end. Indeed, with this data, wherever Yang Wei went, he could proudly straighten his back and raise his head to the sky, and everyone would praise him and say that this angle was unique.
Lu Xiao was not surprised by this data. He was the first to witness the design of the optimized engine parameters and blade materials. He made deductions when he came back. He already had an idea of the approximate data that the engine could achieve, and he had been looking forward to the birth of the real data of the new generation of engines.
This data is within the limit of his deduced range. Wu Tong is amazing. Yang Wei and all the experimental personnel in the 614th Institute must also be striving for perfection, working day and night. They really work hard!
"No problem, President Yang, thank you for your hard work. We will live up to your trust and complete the task beyond expectations!" They will definitely not fall behind, Lu Xiao promised with a firm goal.
The time is too tight. The motherland's birthday and the National Day will not be able to make it in time for the test flight, but they will try their best to ensure that the brand new J-20 takes off smoothly and enters the ranks of service when New Year's Day arrives.
He is also waiting to invite Wu Tong to come to Xizhou to witness the start of the J-20 test flight!
T4 titanium-aluminum alloy, all equipment is connected and in place, officially entering production reserve, just waiting to be put into operation.
According to the expected experimental simulation data, the weight of the whole aircraft is expected to be reduced by nearly one-third compared with the previous weight if the T4 titanium-aluminum alloy is used as the fuselage. If it is equipped with a reduced-load engine, this weight reduction data can be further improved. This data has already caught up with the data of some large-area carbon fiber composite materials, and even exceeds it, and it also avoids some shortcomings of composite materials.
The reduction in weight means that the fighter can fly higher, faster, and farther, while saving fuel, carrying more weapons and equipment, and auxiliary fuel tanks, expanding the combat radius, greatly improving the flight speed and altitude, and making itself flexible and maneuverable to adapt to the needs of air combat.
"Strive to reduce every gram of aircraft weight" is the motto of aircraft designers all over the world. It is also his endless pursuit.
Back then, the Chinese J-7E fighter plane, after painstaking efforts by scientific researchers, successfully reduced its weight by 40 kg. These 40 kg, compared to the huge weight of the fighter plane itself, seem insignificant, but they can actually increase the turning angular velocity of the J-7E fighter plane by nearly 1 degree, increase the climbing speed by more than 3 meters per second, and be able to carry dozens more cannon shells...
Now with the superior performance of T4 and T5 new materials, the J-20's own weight will be reduced to a terrifying level. With a near-perfect aircraft design and a world-class powerful heart, it means that their J-20 can truly soar into the sky, and its speed and performance will be beyond the limit, far exceeding the best expectations before.
Everything is ready, only the east wind is missing!
The fastest speed, the strongest power, the longest endurance, this time, the J-20 will take off in leaps and bounds! Wu Tong checked the data sent by the two bosses. Chief Engineer Yang sent the test data of WS-15S, which was in line with her deduction expectations. Lu Xiao sent detailed wind tunnel simulation data. Following the chief consultant of 614, Lu Xiao also gave Wu Tong a consultant title in 606 Institute, so that he could have access to these materials. Of course, this was based on Wu Tong's confidentiality authority.
Wind simulation is an aerodynamic experimental simulation method that places an aircraft model in a wind tunnel, artificially controls the airflow, studies the gas flow around the aircraft and its interaction with the model, and understands the aerodynamic characteristics of the actual aircraft. Wu Tong recently wants to study the NS equation, and this simulation data is still of great research value to her.
The water flowing in the ocean, the wind rolling in the atmosphere, the airflow around the wings of an airplane... The movement of fluids in nature has always been related to the NS equations, and is described and simulated by the Navier-Stokes equations (NS equations).
The existence and smoothness of the NS equation, as well as the general solution of the NS equation, have always been insurmountable mountains in the mathematical world, firmly trapping mathematicians around the world! Wu Tong challenged this big problem, which is one of the seven major problems of the millennium, without intending to eat a big fat man in one bite and try to solve it immediately.
It is God who can solve any problem instantly, but she is just an ordinary person with a little talent, and she cannot reach the level of God's foresight.
To solve this problem, she still has a lot of room for improvement in both mathematics and physics. However, people always have to have ideas and goals before they can plan towards them.
Just like when you enter elementary school, you will dream of going to Huaqing University or Peking University. No matter which one, you will have to study hard in different stages of elementary school, junior high school and high school to achieve your goal!
Wu Tong is doing exactly this kind of work, stepping up his study of physics, especially fluid mechanics, and researching mathematical nonlinear equations. He is also collecting various data and information related to this sector.
Only after the foundation is laid, she can build a skyscraper and reach the top!
It took Wu Tong a whole day to deduce and study the two sets of data, and he wrote down his thoughts and some questions based on the NS equations and the dynamics perspective.
Under the moonlight, she went to the library and selected the books she needed according to her research direction. This time, books on physics occupied a large space.
Starting from the next day, Wu Tong decided to organize the paper on the co-bond effect model and submit it as soon as possible.
Based on the theoretical model, Wu Tong deduced and completed the verification data and went about his business to spend the last day of September.
At nearly four o'clock in the afternoon, Wu Tong began to pack up and leave her office. She first went to Cheng Huanan's office and said to him, "Teacher, I have to go to the airport to pick up my family. My family will arrive at the airport around five o'clock, so I'm leaving first today!"
Grandpa and uncle prepared in advance, and my parents took an afternoon off. As soon as they got off work at noon, the whole family rushed to the airport and waited for the flight on time. Thanks to Jin Yuan and Wu Jingzhong who had sent Wu Tong to the airport many times to handle the formalities, they were very familiar with the process and did not miss the flight. Wu Tong successfully boarded the flight he usually took and flew to Beijing.
