Chapter 328 Advantages and Disadvantages
Whether it is the explosives section or the radar section, for Wu Tong, they are all within the scope of her current research on the missile optimization topic.
After communicating with the two elders, Wu Tong's mind suddenly became clear about the areas that were originally stuck, and she had a clearer direction for improvement. The bits and pieces of enlightenment became the stepping stone for her to take another solid step forward.
When developing hypersonic missiles, the first thing that cannot be ignored is the definition of hypersonic missiles.
Hypersonic missiles refer to missiles with a maximum speed exceeding Mach 5. Most ballistic missiles also have a maximum speed exceeding Mach 5, which can be considered hypersonic missiles in a broad sense.
However, when we talk about hypersonic missiles now, we usually only refer to hypersonic missiles in a narrow sense, that is, missiles whose main mission is to strike the ground, mainly fly within the atmosphere, have a maximum speed of more than Mach 5, and can perform large-scale maneuvers.
Mach is a unit of speed, 1 Mach is equal to 1 times the speed of sound. That is to say, in the Earth's atmosphere, the flight speed of a hypersonic missile is 5 times the speed of sound, which is about 6,000 kilometers per hour.
In fact, the hypersonic weapons they are going to develop in the future include not only hypersonic missiles, but also hypersonic aircraft and aerospace planes. These weapons are collectively referred to as hypersonic aircraft.
In addition, there is another type of hypersonic weapon called kinetic weapons, also known as hypersonic projectile weapons.
This weapon can increase the speed of the projectile to more than Mach 5. At this speed, the projectile does not even need to be loaded with gunpowder, and the huge kinetic energy alone can cause destructive effects on many targets.
Of course, one has to eat one bite at a time and technology has to be upgraded step by step. Wu Tong has a clear positioning for himself. Now he will focus on developing PL-17 and DF-17 and provide them to the higher authorities as soon as possible for nationwide promotion, thus adding a new chapter to the Chinese weapon!
In addition to hypersonic missiles, the ground-based space agency has also proposed the concept of extremely hypersonic missiles, which have an even more amazing speed, reaching Mach 10 or more!
However, at present, only a very small number of countries have sufficient technology and experience in hypersonic missiles. The current domestic technology in this area is not mature enough. Wu Tong's basic speed requirement for PL-17 is to break Mach 6, and the basic requirement for DF-17 is to break Mach 8-10. She wants to touch the range of the so-called hypersonic missile!
After all, in order to deter the scoundrels from spying on the country, the gap must be widened to make people discouraged!
Hypersonic missiles can even hit a target before the target has time to make a defensive response. Not only must they be fast, but they must also have a special flight trajectory. The combination of speed and flight trajectory can greatly increase the difficulty of identification and interception by the target's aerospace defense system, ensuring that the target is effectively hit.
To put it more exaggeratedly, Wu Tong hopes that the big guy she conquers is fast enough, and the hypersonic missile or very hypersonic missile can ignore the target's defense and directly attack the most important target, so that the rising China will have enough foundation and be more confident and self-reliant!
As long as they have enough ability, everyone has the ambition to make the country strong. Wu Tong is no exception. She also insists on her beliefs.
Wu Tong opened the notebook she carried with her and carefully wrote down the difficulties she needed to overcome in order to achieve her goal. In-depth research, Wu Tong really enjoyed this kind of challenge.
Looking at the data, the problems she has to face are roughly in the areas of thermal protection, high-temperature communication ionization, positioning navigation and timing, maneuverability, aerodynamics, component integration, rapid kill chain, etc.
Wu Tong's mind was working quickly as to how to solve these problems, and her subordinates were following her thoughts and taking notes like a storm.
Structural design, research and development of materials with excellent performance, and powerful radar, these three major sections have been optimized, and her PL-17 and DF-17 have been completed as expected.
In detail, the technical sections and purposes she needs can be broken down into:
Digital array radar, high temperature resistant warhead materials, hypersonic penetration, terminal trajectory maneuvering, Qian's ballistics, waverider technology, and accuracy must be controlled within 50 meters...
Wu Tong listed one by one the technologies that needed to be conquered, or the goals she wanted to achieve. If these requirements could be met, then she was confident that she could make the DF-17 a true aircraft carrier-killer and add a powerful weapon to the Ningliao.
Heat-resistant materials are Wu Tong's forte. They have extensive experience in this area. If the previously developed materials cannot be used, they can take a step further on this basis!
High temperature resistant materials, high temperature resistant coatings, excellent missile outer body materials... In fact, judging by the number, they already have a lot of technical reserves. In the field of heat dissipation coatings, the high temperature resistant coatings they made before are widely applicable, which can be used at this time.
She should be fully prepared for innovation. Wu Tong had never worried about the need for improvement in materials.
Derivation direction, Wu Tong confirmed the general direction, followed up with mathematical calculations, derived detailed parameters and data, and then used the derivation space for simulation, found loopholes, and made modifications...
Transportation technology, engine technology... Although Wu Tong has more or less mastered many areas, he has dabbled in them.
Now that things have really gotten serious, Wu Tong feels that she still needs to stretch and improve the relatively weak areas. The highest water level that a wooden barrel can bear is always based on the shortest board position as the bottom line.
The breakthrough direction of materials, the breakthrough direction of design... one by one is reflected in Wu Tong's mind. Wu Tong's eyes turned deep. He would move mountains when encountering mountains and fill the sea when encountering sea. Wu Tong was never afraid of encountering problems.
Technical difficulties, problems. If there are problems, it means that a certain work has not been done properly. This is the best way to self-check. Although, Wu Tong has basically no risk of making mistakes.
"Mr. Wu, we're home!" While Wu Tong was writing at full speed, the car drove Wu Tong to the basement of his home in Yanyuan smoothly with almost no bumps. After Wu Tong put down his pen and obviously finished thinking, An Wenshu reminded him softly.
The first problem Wu Tong faced was that the missile flew at an astonishing speed of about 1.7 kilometers per second or even higher in the dense atmosphere, which would cause intense friction with the air, generating a large amount of heat, causing the surface temperature of the missile to reach 2200°C, which is higher than that of a fighter plane. If a simple metal heat shield is used, it will increase the mass of the missile, thereby limiting its range and maneuverability, so more advanced means are needed.
In addition, the electronic components inside the monomer generate heat and are difficult to dissipate, so how to prevent them from spontaneously combusting or melting is also a problem.
