Take Off My Aviation Era

"Take off my aviation era (!

Looking at the highly recognizable double-section conical warhead and Professor Yu's introduction, the faces of the military leaders all showed excitement that could not be concealed.

As Professor Yu said, this type of high-altitude "M" ballistic can directly break the missile interception systems of countries outside the territory and achieve a more effective penetration attack.

Once formed, the country will have an advanced attack method no less than the Russian 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 the Russian Iskander missile is an integrated missile system with a non-separable missile body, although the ballistic trajectory for penetration is also the "M" type water-floating mobile trajectory, it can be separated from the body of the JSZB-08 hypersonic warhead. The system is different, the integrated design of the Iskander missile makes the entire missile do "M" type water drift maneuver at high altitude.

The advantage of this is that it is more convenient in design and more powerful when attacking.

However, the shortcomings are also obvious. The first is speed. Iskander claims that the maximum speed can reach Mach 10, but in fact, in addition to being able to maintain a speed of Mach 10 when falling at an altitude of 50 kilometers, the rest can only be at most. Maintained at around Mach 5.

The speed is much lower than the Mach 7 attack speed of the JSZB-08 hypersonic warhead.

Of course, the most important point is the lack of flexibility of Iskander. With the exception of the Iskander missile, similar technologies 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, which is like a fixed ammunition. It can be installed and used as long as the launcher is adapted.

The same is true for the JSZB-08 hypersonic warhead, which can be adapted to various types of domestic M ballistic missiles according to different needs.

Even more powerful medium-range missiles can be assembled as long as conditions permit.

At that time, the range of domestic M missiles will not only be greatly increased, but also the penetration capability will be qualitatively improved. 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 when the warhead is separated from the body is an unavoidable problem.

Iskander's flexibility is insufficient, but the missile body is integrated, which means that the relevant control system has enough space to install. The JSZB-08 hypersonic warhead is flexible, but the total length is only two-fifths of the total length of the entire missile. After removing 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 noticed the problems, so they calmed down quickly, so after the two exchanged in a low voice, the head of the headquarters asked Said: "Professor Yu, as far as I know, the biggest difficulty of Sanger's trajectory is attitude control. Although the JSZB-08 hypersonic warhead has sufficient demonstration in aerodynamic theory, is there any feasible solution for control?"

When Professor Yu heard this, he looked at Zhuang Jianye not far away, meaning that this issue is still yours for Mr. Zhuang.

However, Zhuang Jianye cast an encouraging look at Professor Yu, silently saying that he was unprofessional in this respect, and you should always come by yourself.

When Professor Yu saw it, he could only come on his own, so he explained: "For control issues, the method we currently use is to use satellites to control the warhead's attitude."

"Relay satellite?"

After listening to Professor Yu’s words, the military leaders immediately thought of the three relay satellites in orbit belonging to China Ascendas. Now it has developed to the second generation. In addition to the transmission of relay signals, it is the most important activity. It is equipped with two sets of domestically made cesium atomic clocks, which have certain satellite navigation functions.

Because of this, in addition to verifying space signal transmission and control, thereby reducing dependence on ground stations, the most important item of this second-generation relay satellite is to verify the feasibility of satellite navigation.

Judging from the current results, no matter whether it is the signal transmission between satellites or the air-to-ground communication between satellites and the ground, there is no problem. In theory, it can replace some ground stations to achieve global satellite control and information exchange.

However, the effect of the domestic cesium atomic clock is not very satisfactory, because the delay and error of the time service are extremely large, resulting in extremely inaccurate positioning accuracy.

The reason is not the satellite problem of China's take-off, but the process problem of the cesium atomic clock manufacturer. In other words, the process of producing cesium atomic clocks by domestic manufacturers is not precise enough, resulting in excessive internal errors.

Because of this, the most important purpose of China's participation in the European-led Galileo satellite navigation program is to introduce European cesium atomic clock production technology, so as to achieve leapfrog development in related fields.

It's just that these things are not something that China Ascendas can dominate. Moreover, even if the navigation verification is not successful, it will not affect the transmission and control of the relay satellite.

As long as the relay module is installed on the warhead, the real-time control of the warhead can be realized through the relay satellite.

but……

"Even if a relay satellite is used, the orbits of the three relay satellites are all very high. In this state, can the communication between the warhead and the satellite be kept 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. However, the relay satellites that China took off have an orbital altitude of more than 100 kilometers and are still in a stationary orbit. The three satellites are in contact with each other. All are reluctant. It is not easy for a high-speed warhead to establish contact.

After hearing this, Professor Yu did not appear to be flustered, but still calmly replied: "We can change the orbit of the required satellite!"

"It is not difficult to change the orbit, but it has a great impact on the life of the satellite. How many orbit changes can your satellite support?" At this time, a technical leader from the aerospace department opened his mouth and pointed to the core of the problem.

It is important to know that the small rocket motors and fuel loaded inside the satellite are not used casually, but are adjusted to resist the gravity of the earth, or forced to maneuver to avoid the impact of space junk.

Endless use is equivalent to completely depleting the potential of the satellite~www.readwn.com~ 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. The intervention found that there was no fuel. Should the satellite be scrapped?

Of course, Professor Yu understood the subtext of the technical leader from the aerospace department, and did not give too much explanation. He just said indifferently: "How many times can the third-generation relay satellite that we have just developed? We haven't calculated it yet, because 15,000 hours of uninterrupted kinetic energy output is really difficult to quantify 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 could not answer satisfactorily, he was very annoyed, but the technical leader in the aerospace field stood there stupefied after hearing this, and he wrote me in his heart directly~~~Hall Propeller , Nima, why didn't you say it earlier!
