Chapter 1311

The reason why Zhuang Jianye and others are so sure is very simple. They are not unfamiliar with the target discovery and command and control system, from the yun-6 command plane that was originally provided to the airborne troops for tactical command to the trj-500 radar warning plane that was bidding for the air search of the Navy and air force in the early 1990s.

After careful calculation, from Tengfei group to now China Tengfei has developed three generations of products on this technology line.

Yes, China's take-off in this respect has indeed developed for three generations, but the third generation products have broken away from the shackles of the atmosphere and rushed into outer space. At this point, they have broken away from aviation and become genuine aerospace technology.

Because a synthetic aperture radar imaging module developed by China Tengfei is installed on the No. 3 satellite in the second generation of test satellite constellation, which replaces the first generation of inter satellite communication.

Thus, the feasibility and adaptability of synthetic aperture radar imaging technology developed by China Tengfei will be verified while the 3rd satellite completes the encrypted communication between satellites and completes the global satellite data sharing test with the ground station.

To this end, China Tengfei has invested 600 million yuan in related research and manufacturing, and has prepared one test satellite and two spare replacement satellites for this purpose.

When the No. 3 test satellite in low earth orbit accelerates to the atmosphere according to the test requirements, the constellation gap left must not be filled. After all, the information transmission between satellites, which has invested more than 2 billion yuan, can not be abandoned halfway.

Some people will ask, since the general direction is inconvenient, why should the well-lived No.3 satellite be dropped into the atmosphere?

The reason is very simple, but the anti-ship ballistic missile in the "killer's mace" plan has been steadily advancing. The overall size, range and attack range have been roughly determined, and the corresponding materials and guidance mechanisms have also been conquered one by one.

If not, the headquarters will not be able to require the relevant live ammunition tests to be completed in the first five years of the new century and combat effectiveness to be formed in the first ten years.

However, the smooth development of the whole does not mean that all the details are perfect. Compared with the precision attack system, the precision of the anti-ship ballistic missile warhead is only 8 meters.

If you attack a fixed target on land, the accuracy of 8 meters is enough to kill everything. The problem is that the anti-ship ballistic missile strikes a moving target on the sea. The error of 8 meters is not much, but it is very easy to make a deviation on the vast sea. The absolute error is a thousand li.

Of course, the best way to solve this problem is to install a set of satellite positioning module to ensure the strike accuracy of the reentry warhead with a high-precision satellite positioning system, which is usually within 1 meter.

The problem is that at this time, not to mention the domestic satellite positioning system, our own satellite communication system is not enough, and it is even more impractical to buy foreign related components. Anti ship ballistic missile is a powerful weapon of our country, the killer of conventional equipment. In any case, it is impossible for such important equipment to use equipment that cannot be controlled independently.

At ordinary times, what if foreign countries shut down their satellite positioning system at a critical moment? Is this battle still going to be fought?

So we can only use other methods.

For this reason, China Tengfei, which is leading the work, has tried several high-precision guidance systems, such as laser imaging, starlight guidance and so on, but no matter which guidance system has such and such defects.

For example, the accuracy of laser imaging can reach 0.5 meters, almost reaching the level of "where to go, where to go". However, the effect of laser in bad weather conditions is really touching, the accuracy is plummeting, and the stability is not good.

However, the whole structure of starlight guidance is too complex, which requires not only the integration of inertial navigation and laser gyroscope, but also the setting of complex optical window on the warhead.

In order to achieve hypersonic attack, the reentry warhead of anti-ship ballistic missile is optimized by start-up, which will inevitably sacrifice a certain amount of space, which makes it difficult to integrate the complex starlight guidance into the warhead.

When the precision strike mode of anti-ship ballistic missile is in a bottleneck, the kinetic energy impact warhead used by anti missile and anti satellite system has made great progress.

The kinetic energy warhead uses a kind of synthetic aperture radar technology to realize the accurate tracking and real-time imaging of the incoming ballistic missile, so as to ensure the accuracy of the attack accuracy.

China's take-off is different from other units. It is a high-tech enterprise that has been emphasizing internal technology sharing and deeply tapping technology potential since the 23rd branch.

As Zhuang Jianye often said in China Tengfei group, "after a certain new material and a certain new technology are determined to be mature, the application department should popularize these new materials and new technologies to our product line as far as possible, even if they can be applied on one screw, it can not be wasted. If such screws can be iterated, it can also make a lot of money, Of course, universal application is the best way to dilute our R & D costs, speed up the efficiency of our product upgrading, and then beat our competitors, occupy more markets and grab more profits... "

These words are still on the outside. Zhuang Jianye is expected to be scolded as an inhuman capitalist by those public intellectuals and Notre Dame whores. There is nothing in his eyes but profit and making money.

But the problem is that despite these money factors, China's take-off is indeed the enterprise that has done the best technology transformation in China and the fastest product technology iteration.

Take China's take-off as an example, which is envied and envied by many friends and businessmen. So many domestic manufacturers and supporting plants have not formed a complete pedigree of China's take-off. However, China's take-off has spent a short period of 20 years, from scratch, making three directions including large, medium and small; There are 23 types of WD series aero engines in four categories: turboprop, turboshaft, turbojet and turbofan. On this basis, we have developed gas turbines with competitive advantages.

Especially in recent years, China's take-off has become more and more detached in the domestic aero-engine and gas turbine industry. The reason for this is very simple. The iteration and performance improvement of China's take-off's aero-engine products are very well done. Often, a new material comes out and immediately spreads out in the whole spectrum of aero-engine products, and then the upgraded version of new aero-engine comes out, While the performance is improved, the product line does not change, so we can continue to make money by relying on the original product line without additional investment.

In this way, we can work together to make a group impact, and those single air power plants simply can't resist it.

Because this kind of efficient technology transformation and application can't be learned by any other company. It's true in the air launch business, and the same is true in other businesses of China Tengfei. Since anti missile and anti satellite can use millimeter wave synthetic aperture radar to locate incoming warheads in the vast space, why can't the reentry warheads of anti-ship ballistic missiles follow the same pattern, How to install this set of synthetic aperture radar to locate large water surface targets in the vast sea?
