Invincible Smart-Guy System - Chapter 418

The camouflage and castration of mass production radar function, although not directly beneficial to national defense, can ensure that the current situation will not be turbulent. The appearance of Falcon engine has improved the deterrence of surrounding countries, but it is only from the power level, it has not reached an invincible height, according to the design performance of the j-20, even if it is attached The Falcon engine can not improve its stealth ability, let alone its defense capability against missiles, which is acceptable for neighboring countries and Western countries.

But if the phased array radar of Dongchen is released, I’m afraid that the whole world will be in a mess. The Air Force combat capability of the whole world will be greatly reduced in front of Dongchen. The most important thing is that after Dongchen’s own fighter is equipped with this kind of radar, it will have enough first mover capability, and all the aircraft will have no way to hide in front of it, which can reverse the whole Once the scientific research achievements in the form of air combat are released, they will inevitably be under pressure from all over the world.

Zhang Yunfeng himself is also more inclined to the idea put forward by the senior management. In a normal situation, even the pilot himself can not grasp the essence of a radar with great potential. However, once the critical moment is reached, the radar no longer has the need to hide itself, and directly takes out the real ability. To fight with Ya is to fight, who is still hiding.

In line with this idea, Zhang Yunfeng asked Xiaoer to redesign the radar, so the redesign is to add a new function, the power of the radar and the perception ability of the radar wave are locked to ensure that under normal use, there is no obvious gap with the general phased array radar, so that the exposure probability of the radar is greatly reduced.

Soon, the waiter added a locking module with complete functions on the basis of the original radar. The locking module is remote control. Most of the functions of all radars are locked when they are installed. The terminal for controlling locking will be manufactured separately and provided to the high-level military, and the high-level military will control it fundamentally as long as they input the authorization code and And confirm to unlock, all phased array radars loaded on the fighters will achieve their real detection capability in an instant.

The military’s orders for this kind of anti sky radar are not high. The total number of fighter aircraft, early warning aircraft, ground vehicle and fixed vehicles is no more than 100. Zhang Yunfeng has scheduled the production of the radar after the satellite. After Dongchen has manufactured its own three-dimensional positioning satellite, he will manufacture the radar they need for the military.

More than half a month later, Dongchen’s positioning satellites have all been offline. Zhang Yunfeng has the ability to launch at the same time in the world, that is to say, the first round of launch, Dongchen can launch at least ten satellites into the sky, and basically build a navigation system covering the entire Asia Pacific region. However, in Zhang Yunfeng’s concept, the first phase of launch is only from domestic satellites The launch base will launch four satellites for itself, covering the whole country, so as to carry out the first phase of the test.

In the first phase, the launch task is equally assigned to Xichang and Jiuquan, two old satellite launch centers. Within three days, two Dongchen positioning satellites will be launched one after another. The three-stage launch vehicle with the most complete technology and the highest success rate in China, long march 3a, will be responsible for the launch task.

The launch of the long march 3A carrier rocket has been successful since 1994, without any failure. Moreover, the launch range also meets the needs of positioning satellites. Most of the Beidou positioning satellites are launched into orbit by Beidou, and all of its indicators meet the needs of the Dongchen positioning satellite.

When 40 satellites are ready to be launched in Jiangcheng, Liu Qiyang, chief engineer of Jiuquan Satellite Launch Center, went to Jiangcheng to meet with Zhang Yunfeng. They expect to launch at least five positioning satellites for Dongchen in a limited period of several months in the second half of this year, which is also one of the partners of all cooperative launches of Dongchen. Moreover, the first satellite of Dongchen The Jiuquan Satellite Launch Center is also responsible for the launch of the satellite.

Liu Qiyang went to Jiangcheng in person and visited the positioning satellite that Dongchen was going to deliver to Jiuquan. He was surprised to say, “the volume and weight of the satellite are 400 kg lighter than Beidou, and the volume is reduced by about 25%. The surface area of the solar cell is also reduced by 30% compared with Beidou. In this case, can the satellite ensure sufficient power operation?”

“Of course.” Zhang Yunfeng said with a smile, “our solar panel’s electric energy conversion efficiency is higher than that of the normal panel. In addition, under the condition of the same weight and volume of our battery, the electric capacity is also larger, so it can fully meet the operation requirements.”

Liu Qiyang nodded and said: “the launch window starts at 8:45 p.m. three days later and ends at 11:00 p.m. seven days later. Our current launch plan is that the first satellite will be launched at 10:00 a.m. four days later, and the second satellite will be launched at 8:00 a.m. six days later. The launch vehicle is ready. According to your requirements, we will only launch and enter the orbit It is controlled by Dongchen himself, so after the satellite arrives in Jiuquan, it can be loaded into the carrier rocket, and then it will be launched on time as soon as the launch opportunity arrives, as long as there is no accident. ”

Zhang Yunfeng thought for a moment and asked, “there is a window period of four days. Can we take this opportunity to add another satellite launch?”

Liu Qiyang said: “from the perspective of hardware, the problem is not big. Our launch vehicles are enough, but the biggest problem is that we have never carried out such a dense launch mission. Launching two in four days is already a big challenge for us, let alone three.”

Zhang Yunfeng said: “you don’t have to have too much pressure. You just need to complete every launch in an orderly way. As long as the satellite is put into orbit, all things will be done by ourselves.”

Liu Qiyang thought for a moment and said, “if we just undertake the launch task, then I don’t think it’s a big problem. Now we can put a long march type 3A rocket into the launch state within 24 hours.”

Zhang Yunfeng nodded and said, “then prepare according to the frequency of launching three in four days.”

“If it is based on this launch frequency, insurance companies should not be willing to underwrite the third satellite,” Liu reminded

“No problem.” Zhang Yunfeng waved his hand and said: “if we can launch 80 in four days, half of the loss rate can be borne by Dongchen. We are pursuing speed, not cost.”

Liu Qiyang nodded helplessly on his face. If he undertakes commercial launch under normal circumstances, the entrusting party of launch will generally be entangled in liability and insurance for a long time, because the cost of such a huge launch, once it fails, the insurance company’s compensation will take quite a long time. Moreover, the general enterprise entrusts development or orders to buy a man-made product Satellite, it takes a long time and cost, a failure, even if the insurance company pays in full, their second launch will have to wait a long time before they are ready, but Dongchen doesn’t follow this pattern, they are not afraid to drop the satellite, even if there is no insurance company willing to contract, they are not worried, this kind of wealth, even state-owned enterprises, central enterprises are far from reaching.

Due to the temporary change of the launch plan, from two in four days to three in four days. Liu Qiyang didn’t wait for Dongchen’s satellite to leave. He first flew back to Jiuquan to arrange a new launch mission. Now, the health launch has been much faster than before. The technology of the launch vehicle has been mature, especially the long march three series launch vehicle, which is not only technically mature, but also And the launch frequency is high, so Jiuquan satellite launch base has built its own carrier rocket storage base, so that each launch does not need to use a train transport rocket to enter the launch base. Once there is a launch mission, the base will assemble and debug the reserved carrier rocket, and then the launch can be carried out with fuel before launch.

Liu Qiyang just left, Zhang Yunfeng arranged Dongchen’s own 7478 transport plane to Jiangcheng, two 7478, one carrying three satellites, the other carrying two. In the evening of the same day, they took off successively to Jiuquan and Xichang Satellite Launch centers, while Zhang Yunfeng’s bbj2 business plane flew directly to Jiuquan launch center.

When we arrived in Jiuquan, a long march 3A carrier rocket had been erected on the launch frame. Except for the satellite fairing, the other three-stage rockets had been installed. As soon as Dongchen’s plane landed, the staff immediately transported the three satellites to the assembly room and installed the satellite in the fairing.

There are countless important links in a satellite launch, if it is refined, but generally speaking, there are only two links, one is the launch stage, the other is the satellite into orbit.

Take the long march 3A carrier rocket as an example. The structure of the three-stage rocket makes each stage an independent work unit. Each stage rocket has its own mission to push the rocket to a fixed altitude, then break away from the disintegration, and then ignite the next stage rocket until it finally reaches the predetermined orbit altitude. Then the satellite fairing is opened to release the satellite.

The satellite is successfully released in the predetermined orbit. Even if the launch link is completed successfully, the rest is the satellite’s orbit entry and joint debugging. When the satellite reaches the orbit, it must deploy solar panels in the orbit. This is the core energy of the satellite’s work in outer space. If the satellite reaches the orbit and cannot deploy solar panels, then the satellite is basically abandoned. If the satellite arrives It is a great tragedy that solar panels have been launched and energy problems have been guaranteed, but the ground is unable to contact or control. The people of cold country often make this mistake. When the satellite is in the sky, or they are unwilling to stop when they arrive at the orbit, they continue to send the satellite to a higher position. After sending it up, they lose contact when they can’t move. Finally, it’s over It’s equivalent to spending a lot of money to send a pile of scrap iron to the sky.

Dongchen’s satellite adopts all the high-end technologies in the future, and the technology is extremely stable and reliable. For Dongchen, as long as the launch can not alleviate the problem, the success rate is almost 100%.
