Before returning to the college entrance examination, I became popular in the science circle

"Haha... They're all the same, they're all the same. We won't pick. Once the J-35 project is fully completed, let's enjoy Mr. Lu's craftsmanship and ask Mr. Lu to give us a good demonstration of tea culture!" Lu Xiao has good tea skills. They have long been admired.

Lu Xiao laughed, but did not hesitate, "No problem, the J-35 project has been successfully delivered. I have prepared tea for everyone to drink tea!" When the time comes, he will get some special tea from the old man.He has been working in a research institute for many years and does not have much time to find good tea leaves, so he is somewhat lacking in this area.

"I will also contribute, and I will provide the tea!" Wu Tong smiled and sponsored: "I still have a few taels here. It is said to be the Dahongpao produced by the mother tree in Wuyi Mountain!" This was included in the supply given to her by the above. I don’t know much about tea, so my family only rarely buys it and never runs out.It just adds to the celebration and makes the best use of everything.

"This relationship is great, Mr. Lu's craftsmanship and Mr. Wu's tea, we are in for a treat!"

Suddenly, there was a happy atmosphere in the office.After chatting about daily life, Wu Tong's office was kept strictly confidential and there were no outsiders present. Everyone changed the topic and talked about the J-35 project, and the topic turned to formal content.

Stovl, a version of vertical take-off and landing, which they named Canglong J-35A. After detailed repeated tests and process refinement, "it is expected to enter formal production in the first month and be equipped with the Ningling and coastal fleets as soon as possible." superior!"

This is good news. Wu Tong feels that she should move faster. It is best to catch up with the Canglong J-35A before it officially enters service, and solve the big missile issue that has begun to unfold, and help the Canglong J-35A and their Aircraft carrier group.

After chatting about the J-35 project team, Wu Tong was not polite to his seniors, "Gong Zhan, Professor Feng, these are the detailed aerodynamic layout drawings of the Canglong J-35 conventional take-off and landing version and the carrier-based version. You should study it first." , I’m asking Brother Lu to ask some questions!”

Lu Xiao can be said to be a leader in the country in the field of aerospace dynamics. Wu Tong's research and development and design of new missiles are some of Lu Xiao's areas of expertise. She originally planned to take some time to have a video conference with Lu Xiao. Please discuss this aspect.

When it comes to things that can quickly speed up the process, Wu Tong never mind asking others for their expertise and using their strengths to make up for his own shortcomings.Instead, you have to bite the bullet, embarrass yourself, and deduce it step by step.

It is true that she has the ability to deduce, but she can easily solve the problem of asking for advice. It is really unwise for her to waste that time to study silently. She does not have the baggage of those figures that she cannot let go of.A master is a teacher, and there is no shame in asking for advice.

"Brother Lu, I will start a new project after this year. Regarding the preliminary research on upgrading air-to-air missiles and ballistic missiles, I will temporarily name them PL-17 and DF-17. The PL-17 air-to-air missile is based on the previous PL-15 Upgrading to increase the range and combat power is a step-by-step matter, and the main area I need to research at the moment is hypersonic missiles!"

Wu Tong and Lu Xiao talked about the current problem and the areas she had a rough idea of ​​conquering.Now, the most critical part is actually Wu Tong's reform design of the single head.

"Brother Lu, you understand better than me that the parabolic trajectory of conventional missiles is too easy to be detected and intercepted by anti-missile systems. I want to make ballistic missiles have the orbit-changing ability of cruise missiles based on the previous Qian's trajectory. In this regard, The commonly used conical warheads can no longer meet my design requirements. Based on dynamics, angle of attack issues, and air-breaking resistance..." Wu Tong briefly talked to Lu Xiao about her ideas and the areas that currently need help. bright.She needed Lu Xiao's assistance to help her complete the design of the new warhead, and the subsequent launch of the rocket body was also innovating and optimizing the scope.If you want to do something, you must do your best.

"Improvement is an inevitable demand. From my understanding, we need to take into account the lift-to-drag ratio and volume ratio, and be able to carry high-power conventional warheads for hypersonic gliding, so that our target products have flexible horizontal and vertical maneuverability. Track..." In Wu Tong's explanation, Lu Xiao quickly caught up with Wu Tong's thinking, synchronized with it, and provided Wu Tong with help moving forward in the areas he was good at.

Lu Xiao spared no effort and made full use of his reserves in physics and dynamics. He had a mental collision with Wu Tong and tried his best to give Wu Tong the help and guidance he needed. New designs slowly appeared in Wu Tong's mind during the collision. Tong is thinking about it.

After sending away Lu Xiao, Zhan Gong and others, Wu Tong slowly improved the warhead design layout, abandoning the conventional conical warheads and using the new missile, Wu Tong used a waverider aerodynamic shape.

As an aerodynamic layout design suitable for hypersonic flight, the waverider can allow the leading edge of the warhead to carry attached shock waves.In this way, the warhead can rely on the shock wave to generate additional lift and perform a motion similar to "floating on water."

Hypersonic gliding warheads that have appeared in the world before are all bicone designs. Compared with warheads of other designs, bicone hypersonic gliding warheads have a slightly stronger lift-to-drag ratio, which can minimize the resistance of the warhead. Extend the warhead range, etc.

However, compared with the double-cone design, the aerodynamic shape of the waverider warhead has a stronger lift-to-drag ratio. When it is launched, it is like "riding" directly on the shock wave, which can ensure The warhead is less likely to be intercepted and can also extend its range better.

As for the extremely high material requirements brought about by the difficult design, this problem is actually not difficult to solve for Wu Tong. .
When she was developing the PL-15 air-to-air missile, she did effective research on missile body materials. For this purpose, she developed a new type of special steel MC-4, which itself is a very good high-temperature resistant material.

However, the performance of this material is sufficient for the PL-6, which can reach Mach 15, and is sufficient for use in the atmosphere. However, it is still not limited enough for use on ultra-high or even hypersonic missiles.

This is actually determined by the performance of the missile.Hypersonic missiles start at speeds above Mach 5, or even higher. Wu Tong also wants to have higher performance requirements for missiles on the basis of pursuing higher speeds. So year-on-year, the performance requirements for materials are also Naturally, it increases in direct proportion.

On this basis, she needs to continue to improve the performance of the projectile material, so that it can still maintain mechanical properties and even achieve zero burn at ultra-high temperatures starting from two to three thousand degrees.

In this way, the requirements for material performance cannot only be achieved by simple steel materials.Wu Tong is also skilled in alloy materials. When thinking about the problem, Wu Tong is already thinking about what kind of material can best withstand high temperatures.
