- Looking at the highly recognizable double-section conical warhead and Professor Yu's introduction, the faces of the military leaders all showed unconcealable excitement.
As Professor Yu said, this high-altitude "M"-type ballistics can directly break the missile interception systems of foreign countries and achieve more effective penetration strikes.
Once it takes shape, the country will have an advanced attack method that is no less than Russia's Iskander missile.
No It should be said that the jszb-08 hypersonic warhead led by Professor Yu is more flexible and efficient than the Iskander missile.
Because Russia's Iskander missile is an integrated missile system with a non-separable missile body, although the ballistic trajectory of the penetration is also an "M" type water-floating mobile ballistics, which can be separated from the body of the jszb-08 hypersonic warhead The system is different. The integrated design of the Iskander missile allows the entire missile to perform an "M" type water-floating maneuver at high altitudes.
The advantage of this is that it is more convenient in design and more powerful in attack.
However, the shortcomings are also obvious. The first is speed. Iskander claims that the maximum speed can reach Mach 10, but in fact, except for being able to maintain a speed of Mach 10 when performing water-floating maneuvers while falling at an altitude of 50 kilometers, the rest can only reach Mach 10 at most. Maintained at around Mach 5.
The speed is much smaller than the Mach 7 attack speed of the jszb-08 hypersonic warhead.
Of course, the most important point is that Iskander is not flexible enough. Except for the Iskander missile, similar technology cannot be replicated on other Russian missiles.
The jszb-08 hypersonic warhead is different. After all, the jszb-08 hypersonic warhead is just a warhead, just like a custom-installed ammunition. It can be installed and used as long as the launcher is adapted.
The same goes for the jszb-08 hypersonic warhead, which can be adapted to various domestic M-family ballistic missiles according to different needs.
Even more powerful medium-range missiles can be assembled as long as conditions permit.
By then, domestic M-family missiles will not only have a significantly increased range, but also a qualitative improvement in defense penetration capabilities. From this perspective, the jszb-08 hypersonic warhead is far more forward-looking than Iskander.
Of course, the jszb-08 hypersonic warhead has advantages and disadvantages. The biggest one is that the control of the warhead when it is separated from the projectile body is an unavoidable problem.
Iskander is not flexible enough, but the missile body is integrated, which means that there is enough space for the relevant control system to be installed. The jszb-08 hypersonic warhead is flexible, but the total length is only two-fifths of the entire missile. , after excluding the nearly 500 kilograms of warhead, there is not much space left.
Although the military leaders and the head of the headquarters were excited about the jszb-08 hypersonic warhead, they quickly saw the problems and calmed down quickly. After the two exchanged words in a low voice, the head of the headquarters asked Said: "Professor Yu, as far as I know, the biggest difficulty in Sanger's ballistics is attitude control. Although the jszb-08 hypersonic warhead has sufficient theoretical demonstration of aerodynamics, is there any feasible solution in terms of control?"
Professor Yu heard this and looked at Zhuang Jianye, who was not far away. He meant that Mr. Zhuang should answer this question.
Zhuang Jianye, however, cast an encouraging look at Professor Yu, silently indicating that he was not professional in this area, so you should do it yourself.
Professor Yu saw that he could only do it himself, so he explained: "As for the control problem, the method we currently use is to use satellites to control the attitude of the warhead."
"Relay satellite?"
After listening to Professor Yu's words, the military leaders immediately thought of the three in-orbit relay satellites owned by China Ascendas. Now they have developed to the second generation. In addition to transmitting relay signals, one of the most important activities is It is equipped with two sets of domestically produced cesium atomic clocks, thus having a certain satellite navigation function.
Because of this, in addition to verifying space signal transmission and control, thereby reducing dependence on ground stations, the most important thing for this second-generation relay satellite is to verify the feasibility of satellite navigation.
Judging from the current results, there is no problem in signal transmission between satellites or air-to-ground communication between satellites and the ground. In theory, it can replace some ground stations and realize the control and information exchange of satellites around the world.
But the effect of domestic cesium atomic clocks is not very ideal, because the delay and error in timing are extremely large, resulting in extremely inaccurate positioning accuracy.
The reason is not a problem with China's takeoff satellite, but a process problem with the cesium atomic clock manufacturer. In other words, the process of domestic manufacturers producing cesium atomic clocks is not precise enough, resulting in excessive internal errors.
Because of this, it is most important for China to join the European-led Galileo satellite navigation program.The main purpose is to introduce European cesium atomic clock production technology to achieve leapfrog development in related fields.
¡°It¡¯s just that these matters are not something that China Ascendas can lead, not to mention that even if the navigation verification is unsuccessful, it will not affect the transmission and control functions of the relay satellite.
As long as a relay module is installed on the warhead, real-time control of the warhead can be achieved through relay satellites.
but¡¡
"Even if relay satellites are used, the orbits of the three relay satellites are all very high. In this state, can the connection between the warhead and the satellites be guaranteed to be smooth?"
At this time, the head of the headquarters raised a sharp and realistic question. Relay satellites can indeed solve the problem of warhead control, but the orbital altitude of China's takeoff relay satellite is more than 100 kilometers, and it is still in orbit. The three satellites are in contact with each other. It's all barely possible. It's not easy for a high-speed flying warhead to establish contact.
After hearing this, Professor Yu did not appear panicked, but still calmly replied: "We can change the orbit of the required satellites!"
"It is not difficult to change orbits, but it has a great impact on the life of the satellite. How many times can your satellite support orbit changes?" At this time, a technical leader from the aerospace department spoke up, pointing directly to the core of the problem.
You must know that the small rocket engines and fuel loaded inside the satellite are not used casually, but are attitude adjustments made to resist the gravity of the earth, or forced to maneuver to avoid the impact of space debris.
Endless use is equivalent to completely depleting the potential of the satellite. After all, no one can guarantee that the satellite will not encounter space junk in orbit and will not gradually fall into the atmosphere due to the gravity of the earth. When the time comes to prepare for intervention, it will be found that there is no fuel. , do you want to watch the satellite become scrapped?
Of course Professor Yu understood the subtext of the technical leader who came from the aerospace sector, and did not explain too much. He just said lightly: "How many times can the third-generation relay satellite we just developed make orbit changes?" We haven¡¯t really calculated it yet, because 15,000 hours of uninterrupted kinetic energy output is really difficult to quantify into several times. After all, the quantitative index of our dpz-06 Hall thruster can only be calculated in hours.¡±
When he said this, Professor Yu frowned, as if he was annoyed that he could not answer satisfactorily, but after hearing this, the technical leader in the aerospace field froze there, and in his heart he directly said FUCK~~~Hall Thruster , Nima, why didn¡¯t you tell me earlier!
