"Haha...it's all the same, all the same. We are not picky. When the J-35 project is completely completed, we will learn from Mr. Lu's craftsmanship and ask him to demonstrate the tea culture to us!" Lu Xiao is a good tea artist, and they have long admired him.
Lu Xiao laughed, but didn't hesitate. "No problem, the J-35 project has been successfully delivered. I'll prepare some tea, everyone! " He would get some special tea from the old man when the time came. He had been working at the research institute for most of these years and didn't have much time to look for good tea, so he was a little short of this.
"I'll do my bit, too. I'll provide the tea!" Wu Tong offered with a smile, "I still have a few ounces here. It's said to be Dahongpao grown on the mother tree in Wuyi Mountain!" This was part of the supply she received from higher-ups. She wasn't a big tea expert, so her family only enjoyed it, and there wasn't enough left. It was a perfect way to add to the celebration and make the most of it.
"That's great! Mr. Lu's cooking skills and Mr. Wu's tea are so good! We're in for a real treat!"
Suddenly, a cheerful atmosphere permeated the office. After chatting about daily life, Wu Tong's office was strictly confidential, and no outsiders were present. They changed the subject and discussed the J-35 project, turning to the actual content.
The vertical take-off and landing version, named the Canglong J-35A, has undergone extensive testing and refinement. "It is expected to enter formal production after the first month of the lunar calendar, and will be deployed on the Ningliao and the coastal fleet as soon as possible!"
This is good news. Wu Tong feels that she should act faster. It would be best if she could complete the major missile project at hand before the Canglong J-35A officially enters service, to help the Canglong J-35A and their aircraft carrier fleet.
After discussing the J-35 project team, Wu Tong didn't hesitate to greet his senior colleagues. "Engineer Zhan, Professor Feng, here are the detailed aerodynamic layouts for the Canglong J-35's conventional takeoff and landing version and carrier-based version. You guys study them first. I'll consult Brother Lu on some questions!"
Lu Xiao can be said to be a leader in the field of aerospace dynamics in China. Wu Tong's research and development and design of new missiles are somewhat within Lu Xiao's professional field. She had originally planned to take some time to have a video conference with Lu Xiao to consult and discuss this matter.
When it comes to things that can speed up the process, Wu Tong never hesitates to ask for advice, learn from others' expertise, and use their strengths to make up for his own shortcomings. Instead of forcing himself to figure things out on his own, putting himself in a difficult position and using clumsy methods to deduce them step by step.
It's true that she has the ability to deduce this, but wasting her time silently studying the problem she's seeking advice for could easily be solved. She doesn't have the baggage of those lingering concerns. A learned person is a teacher, and there's no shame in asking for advice.
"Brother Lu, I've started a new project after the New Year. It's preliminary research on upgraded air-to-air missiles and ballistic missiles. I've tentatively named them PL-17 and DF-17. The PL-17 air-to-air missile will be an upgrade of the previous PL-15, increasing its range and combat power. This is a step-by-step process. My main research area right now is still hypersonic missiles!"
Wu Tong and Lu Xiao discussed the current problems and the areas she had a rough idea of how to tackle them. The most crucial part now was Wu Tong's design for the single-head reform.
"Brother Lu, you understand better than me that conventional missile parabolic trajectories are too easily detected and intercepted by anti-missile systems. I want to build on the Qian-style ballistics to give ballistic missiles the ability to change their trajectory like cruise missiles. In this regard, the commonly used conical warheads no longer meet my design requirements, based on dynamics, angle of attack, and air resistance..."
Wu Tong briefly explained her vision and the areas where she needed help to Lu Xiao. She needed his assistance to complete the design of the new warhead, and the subsequent launcher body was also in the process of being innovated and optimized. If she was going to do something, she had to do it to the best of her ability.
"Improvement is an inevitable need. From my perspective, we need to take into account both the lift-to-drag ratio and the volume ratio, and be able to carry high-powered conventional warheads for hypersonic gliding, so that our target product has flexible horizontal and vertical maneuvering and trajectory changes..." During Wu Tong's explanation, Lu Xiao quickly caught up with Wu Tong's thinking and synchronized with him, providing Wu Tong with forward momentum in the areas he excels at.
Lu Xiao spared no effort and made full use of his reserves in physical dynamics to engage in a brainstorming session with Wu Tong, trying his best to provide Wu Tong with the support and guidance he needed. A new design slowly emerged in Wu Tong's vision during the collision.
After sending Lu Xiao, Zhan Gong and others away, Wu Tong slowly perfected the warhead design layout, abandoning the previously used conical warhead. For the new missile, Wu Tong used a waverider aerodynamic shape.
As an aerodynamic layout design suitable for hypersonic flight, the waverider can carry the leading edge of the warhead with attached shock waves. In this way, the warhead can rely on the shock waves to generate additional lift, performing a motion similar to "skipping stones on water".
All hypersonic glide warheads that have appeared in the world before are of double-cone design. Compared with warheads of other designs, double-cone hypersonic glide warheads have a slightly stronger lift-to-drag ratio, which can minimize the resistance experienced by the warhead and extend the range of the warhead.
However, compared with the double-cone design, the lift-to-drag ratio of the warhead with the waverider aerodynamic shape is obviously stronger. When it is launched, it is like "riding" directly on the shock wave, which can not only ensure that the warhead is not so easy to be intercepted, but also better extend the range of the warhead.
As for the extremely high material requirements brought about by the difficult design, this problem is actually not difficult for Wu Tong to solve.
When she was developing the PL-15 air-to-air missile, she made effective research on the missile body material and developed a new type of special steel MC-4, which is itself a very good high-temperature resistant material.
However, the performance of this material is only enough for the PL-15, which can reach a speed of Mach 6, and is sufficient for use within the atmosphere. However, it is still not limited enough for her to use it in ultra-high or even hypersonic impact missiles.
This is actually determined by the missile's performance. Hypersonic missiles start at speeds above Mach 5, or even higher. Wu Tong also wants to pursue higher speeds and higher performance requirements for missiles. Therefore, the performance requirements for various materials will naturally increase proportionally.
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 burning at ultra-high temperatures starting from two to three thousand degrees.
As a result, the material performance requirements are not simply met by steel alone. Wu Tong is also adept at alloy materials. When thinking about the problem, Wu Tong is also considering what kind of material can best withstand high temperatures.
