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

Whether it is the explosives section or the radar section, for Wu Tong, they are the scope of the missile re-optimization topic she is currently studying.

After communicating with the two elders, Wu Tong's mind suddenly became clear where there were some slight lags, and he had a clearer direction for improvement.The wisps of understanding turned into a step of assistance for her to move forward firmly again.

When developing hypersonic missiles, the first thing that cannot be ignored is the definition of hypersonic missiles.

Hypersonic missiles refer, broadly speaking, to missiles with a maximum speed exceeding Mach 5.The maximum speed of most ballistic missiles exceeds Mach 5, and they are considered hypersonic missiles in a broad sense.

However, when hypersonic missiles are mentioned now, they are usually only hypersonic missiles in a narrow sense, that is, missiles with the main mission of ground strike, mainly flying in the atmosphere, with a maximum speed exceeding Mach 5 and capable of large-scale maneuvers.

Mach is a unit of speed, and 1 Mach is equal to 1 times the speed of sound. In other words, in the earth's atmosphere, the flight speed of a hypersonic missile is 5 times the speed of sound, which is almost 6000 kilometers per hour.

In fact, the hypersonic weapons they will develop in the future are not only hypersonic missiles, but also hypersonic aircraft and aerospace aircraft. These weapons are collectively called hypersonic aircraft.

In addition, there is another type of hypersonic weapon called kinetic energy weapon, also called hypersonic projectile weapon.

This weapon can increase the speed of projectiles to over Mach 5.At this speed, the projectiles do not even need to be loaded with gunpowder, and can destroy many targets just by relying on huge kinetic energy.

Of course, the meal must be eaten one bite at a time, and the technology must be upgraded step by step. Wu Tong is very clear about his positioning. Now he will focus on developing PL-17 and DF-17 and provide them to the superiors as soon as possible for national promotion. Chinese weapon, adds a new chapter!
UI.Across the sea, on top of hypersonic missiles, the space agency on the ground has also proposed the concept of extremely hypersonic missiles. The speed of this missile is even more amazing and can reach a Mach number of 10 or more!

However, at present, only a handful 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 the PL-17 is to break 17, and the basic requirement for the DF-8 is to break Mach 10-[-]. She thought, go and touch it, the so-called extremely superb. The range of sonic missiles!

After all, in order to deter Xiaoxiao from peeking at the country, we still have to widen the gap so deeply that it makes people flinch!
Hypersonic missiles can hit the target even before the target has time to respond defensively. It must not only be fast, but also have a special flight trajectory. The combination of speed and flight trajectory can greatly increase the effectiveness of the target's air and space defense system. Identify and intercept difficulty to ensure effective target hitting.

To put it more exaggeratedly, Wu Tong hopes that the big guy she conquered is fast enough. Hypersonic missiles or ultra-hypersonic missiles can ignore the defense power of the target and directly attack the most important target, so that the rising China can... Have enough foundation and become more confident and self-reliant!
As long as they have enough ability, everyone has the ambition to strengthen the country, and Wu Tong is no exception. She also, just like her own beliefs,
Spreading out the notebook she carried with her, Wu Tong carefully wrote on it and added the difficulties she needed to overcome if she wanted to achieve her goal.After further research, Wu Tong likes this kind of breakthrough.

Looking at the data, the problems she has to face are roughly thermal protection, high-temperature communication ionization, positioning, navigation and timing, mobility, aerodynamics, component integration, rapid kill chain... etc. aspect.

How to solve and overcome these problems, Wu Tong's mind was running rapidly, and his men were following her thoughts like a storm, taking shorthand notes.Structural design, coupled with the 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.

Broken down, the technical sectors and purposes she needs can be broken down into:
Digital array radar, high-temperature-resistant warhead materials, hypersonic penetration, terminal change maneuvers, and Qian's ballistics, waverider technology, and accuracy must be controlled within 50 meters...

Wu Tong listed one by one the technologies they need to overcome, or the goals she wants to achieve. If these needs can be achieved, then she is confident that she can build the DF-17 into a real aircraft carrier-killer and serve Ningliao The number adds a big weapon.

Heat-resistant materials are Wu Tong’s specialty. They have profound experience in this sector. If the previous research and development materials cannot be used, they can just take one step closer on this basis!

High-temperature-resistant materials, high-temperature-resistant coatings, excellent missile outer body materials... In fact, judging from the counting, they already have a lot of technical reserves.As for the burning heat-dissipation coating section, high-temperature resistant coatings have been made in the past and are widely used. This can be used just now.

Innovating with the old and bringing forth the new is something she should be fully prepared for.The areas that need improvement in materials have never been something Wu Tong needs to worry about.

For the derivation direction, Wu Tong confirmed the general direction, kept up with the mathematical calculations, derived detailed parameters and data, and then used the derivation space to simulate, find loopholes, and make modifications...
Transportation technology, engine technology..., although there are many fields involved, Wu Tong has more or less mastered them.

Now that she is really on the line, Wu Tong feels that she still needs to stretch and improve all the relatively weak areas.The highest water level that a wooden barrel can carry has always been based on the position of the shortest board as the bottom line.

The breakthrough direction of materials, the breakthrough direction of design... are reflected in Wu Tong's mind one by one. Wu Tong's eyes turn deep. When encountering mountains and mountains, and sea reclamation, Wu Tong is never afraid of encountering problems.

Technical difficulties, problems encountered.If there is a problem, it means that a certain job is not done properly. This is the best way to self-check.Although, Wu Tong basically has no risk of making mistakes.

"Mr. Wu, we're home!" While Wu Tong was driving in the wind and rain, the car drove Wu Tong into the basement of Yanyuan's home smoothly and without any bumps. When Wu Tong paused his writing and clearly finished thinking, An Wenshu reminded him softly. .

The first problem Wu Tong faced was that the missile flew in a dense atmosphere at an astonishing speed of almost 1.7 kilometers per second or even higher. It would rub violently with the air and generate a large amount of heat, causing the surface temperature of the projectile to reach 2200°C. , which is better than that of a fighter jet.If a simple metal heat shield is used, it will increase the mass of the missile, thereby limiting the range and maneuverability, so more advanced means are required.

In addition, the various electronic components inside the monomer generate heat themselves and are inconvenient to dissipate heat. How to prevent them from spontaneous combustion or melting is also a problem.
