Yang Wei reported the relevant data concisely and powerfully, and breathed a sigh of relief!
Now, this kid 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, the fighter's radar, flight control, combustion, weapons, etc. are also of paramount importance. Now, the engine has been greatly improved, providing strong and sufficient power for these parts.
Through the phone line, Lu Xiao could feel the strong sense of pride and arrogance of the person on the other end. Indeed, with this data, wherever Mr. Yang Wei went, he would 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, and he made deductions when he came back. He already had a rough idea of the 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 of the 614th Institute must also be striving for excellence and working day and night. They are really working hard!
"No problem, Mr. 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.
Time is too tight. The test flight will not be possible due to the motherland's birthday and the National Day. However, they will try their best to ensure that the brand new J-20 can take off smoothly and enter service by the time New Year arrives.
He is also waiting to invite Wu Tong to come to Xizhou to witness the launch of the J-20 test flight!
T4 titanium aluminum alloy, all equipment is connected and in place, officially entering the production reserve, just waiting to be put into operation.
According to projected experimental simulation data, using T4 titanium-aluminum alloy for the fuselage could reduce the aircraft's weight by nearly one-third compared to previous models. This weight reduction could be further increased if a reduced-weight engine is added. This figure is already approaching or even surpassing that of some large-area carbon fiber composite materials, while also avoiding some of the 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.
"Striving to reduce every gram of aircraft weight" is the motto of aircraft designers around the world. It is also his endless pursuit.
Back then, the Chinese J-7E fighter jet, after painstaking efforts, successfully reduced its weight by 40 kg. These 40 kg may seem insignificant compared to the fighter jet's own massive weight, but they can actually increase the J-7E fighter's turning angular velocity by nearly 1 degree, its climbing speed by more than 3 meters per second, and allow it to carry dozens more cannon shells.
Now, with the superior performance of the new T4 and T5 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!
With the fastest speed, the strongest power and the longest endurance, this time, the J-20 will take off in a big way!
Wu Tong reviewed the data sent by the two leaders. Chief Engineer Yang's data included WS-15S test data, which matched her predictions. Lu Xiao's data included detailed wind tunnel simulation data. Following his appointment as Chief Consultant at 614, Lu Xiao also gave Wu Tong a consultant position at 606, giving him legitimate access to the data. Of course, this was based on Wu Tong's existing confidentiality clearance.
Wind simulation is an aerodynamic experimental simulation method that involves placing an aircraft model in a wind tunnel and artificially controlling the airflow to study the flow of air around the aircraft and its interaction with the model in order to understand the aerodynamic characteristics of the actual aircraft. Wu Tong recently wanted to study the NS equations, and this simulation data was of great research value to her.
The water flowing in the ocean, the wind rolling in the atmosphere, the airflow flowing 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 its general solution, have always been insurmountable obstacles in mathematics, firmly entrapping mathematicians worldwide! Wu Tong took on this major problem, one of the seven major problems of the Millennium Development Goals, without intending to tackle it all at once.
It was God who could solve any problem instantly, but she was just an ordinary person with a little talent, and she couldn't 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, one must first have an idea and a goal before planning towards it.
Just like when you first enter primary school, you will dream of going to Tsinghua University or Peking University. No matter which one, you still have to study hard in different stages of primary school, junior high school and high school to achieve your goal!
Wu Tong is doing exactly this kind of work, increasing his study of physics, especially fluid mechanics, and his research on mathematical nonlinear equations... He is also collecting various data and information related to this sector...
Only after the foundation is laid can she build a skyscraper and possibly top it out!
It took Wu Tong a 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 spent the last day of September step by step.
Around 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. They will arrive at the airport around five o'clock, so I'm leaving first!"
Grandpa and his uncle prepared in advance, and Mom and Dad each took the afternoon off. As soon as they got off work at noon, the whole family rushed to the airport, waiting to board the flight on time. Thanks to Jin Yuan and Wu Jingzhong, who had taken Wu Tong to flights many times and were familiar with the process, they didn't miss their flight and boarded Wu Tong's usual flight to Beijing without delay.
