Functional camouflage castration of mass production radar, for national defense, although there is no direct benefit, but it can ensure that the current situation is not turbulent, the emergence of the Falcon engine, the deterrence of surrounding countries has been improved, but that is only from the power level, has not yet reached an invincible height, according to the design performance of the J-20, even if it is equipped with the Falcon engine, it is impossible to improve its stealth ability, let alone improve its defense capability against missiles, This is acceptable for neighboring countries, as well as for Western countries.

But if Dongchen's phased array radar is announced, I am afraid that the whole world will be chaotic, and the world's air force strike capability will be greatly reduced in front of Dongchen, and the most important thing is that Dongchen's own fighters, after being equipped with this radar, will have enough preemptive capabilities, and all aircraft have nothing to hide in front of it, which is simply a scientific research achievement that can reverse the entire form of air combat, once released, it will inevitably be pressured from all over the world.

Zhang Wenhao himself is also more inclined to the idea put forward by the high-level, a radar with great potential, in a normal situation, even the pilot himself can not grasp the essence of it, but once it reaches the critical moment, this kind of radar no longer has the need to hide itself, and directly take out the real ability, and fight to the death, who is still hiding.

In line with this idea, Zhang Wenhao asked Xiao Er to redesign the radar, so the redesign is to add a new function, the power of the radar and the perception of radar waves are locked, to ensure that under normal use, there is no obvious gap with the general phased array radar. And so it goes. This greatly reduces the exposure rate of this radar.

Soon. On the basis of the original radar, Xiao Er added a fully functional locking module, the locking module is remote control, all the radars, most of the functions at the time of installation are locked, and the control locking terminal will be manufactured separately and provided to the military high-level, and the military high-level will fundamentally control it. As soon as they enter the authorization code and are sure to unlock it, all phased array radars loaded on the aircraft will reach their true detection capability in an instant.

The military's order for this kind of anti-sky radar is not high, fighter planes, early warning aircraft, ground vehicle-mounted and fixed a total of only more than 100 sets, Zhang Wenhao scheduled the production of radar after the satellite, and after Dongchen manufactured his own stereo positioning satellite, he would manufacture the radar they needed for the military.

Half a month later, Dongchen's positioning satellites have all been offline, and Zhang Wenhao has the ability to launch at the same time in the world, that is, the first round of launches. Dongchen can launch at least 10 satellites into the sky, and can basically build a navigation system covering the entire Asia-Pacific region. However, in Zhang Wenhao's concept, the first stage of launch is only carried out by domestic satellite launch bases, which will launch four satellites for themselves, covering the whole country, so as to carry out the first stage of testing.

The first phase of the launch mission is evenly distributed to the two old satellite launch centers in Xichang and Jiuquan, and the two satellite launch centers will each launch two Dongchen positioning satellites within three days, and the launch mission is China's most technologically complete and highest success rate of the three-stage carrier rocket, the Long March 3A.

The Long March-3A carrier rocket, from 94 to the present, all the launches have been successful, without a single failure, and the launch range also meets the needs of positioning satellites, most of the Beidou positioning satellites are launched into orbit by them, and its various indicators also meet the needs of Dongchen positioning satellites.

When the 40 satellites were ready to be launched in Jiangcheng, Liu Qiyang, chief engineer of the Jiuquan Satellite Launch Center, went to Jiangcheng to meet Zhang Wenhao, and they expected 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 the heaviest task among all the partners of Dongchen to cooperate in launching, and the launch of Dongchen's first satellite will also be undertaken by the Jiuquan Satellite Launch Center.

Liu Qiyang said in surprise after going to Jiangcheng and visiting the positioning satellite that Dongchen was preparing to transport to Jiuquan: "The volume and weight of the satellite are 400 kilograms lighter than that of Beidou, the volume has also been reduced by about 25%, and the surface area of solar cells has been reduced by 30% compared with Beidou. ”

"Of course." Zhang Wenhao said with a smile: "The power conversion efficiency of our solar panels is higher than that of normal panels, and the power volume of our batteries is also larger when they have the same weight and volume, so they can fully meet the needs of operation." ”

Liu Qiyang nodded and said: "The launch window starts at 8:45 p.m. three days later, and continues to 11 p.m. seven days later, our current launch plan is that the first satellite will be at 10 a.m. in four days, and the second satellite will be at 8 a.m. in six days. As long as there are no surprises, the satellite will be launched on time. ”

Zhang Wenhao thought for a while and asked: "There are four days in the window period, can we take this opportunity to add another satellite to launch?" ”

Liu Qiyang said: "From the hardware point of view, there is not much of a problem, our launch vehicles are enough, but the biggest problem is that we have never carried out such a dense launch mission, and it is already a big challenge for us to launch two in four days, let alone launch three." ”

Zhang Wenhao said: "You don't have to have too much pressure, it's nothing more than to complete every launch in an orderly manner, as long as the satellite is put into orbit, everything will be done by ourselves." ”

Liu Qiyang pondered for a moment and said: "If it is just to undertake the launch mission, then I think it is not a big problem, we can now put a Long March 3A rocket into the state of waiting for launch within 24 hours." ”

Zhang Wenhao nodded and said, "Then prepare according to the frequency of launching three in four days." ”

Liu Qiyang reminded: "If it is according to this launch frequency, the insurance company should not be willing to insure the third satellite." ”

"No problem." Zhang Wenhao waved his hand and said: "If eighty missiles can be launched within four days, half of the loss rate Dongchen can fully bear, what we are pursuing is speed, not cost." ”

Liu Qiyang nodded helplessly, if it is an ordinary commercial launch, the launch entrusting party 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 a long time, and the general enterprise entrusts the development or order to buy an artificial 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 for a long time to be ready, But Dongchen doesn't follow this routine, they are not afraid of dropping satellites, 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 the original two in four days to three in four days, Liu Qiyang did not wait for Dongchen's satellite to start, he took the first step back to Jiuquan to arrange a new launch mission, now the sanitary launch has been much faster than before, the technology of the launch vehicle has matured, especially the Long March 3 series of carrier rockets, not only the technology is mature, but also the launch frequency is high, so the Jiuquan satellite launch base has built its own carrier rocket reserve, so There is no need to transport rockets by train to the launch base for each launch, and once there is a launch mission, the base will assemble and debug the carrier rocket in reserve, and then fill the fuel before launch to launch.

As soon as Liu Qiyang left on the front foot, Zhang Wenhao arranged for Dongchen's own 747-8 transport plane to go to Jiangcheng, two 747-8s, one carrying three satellites and the other carrying two, took off successively in the evening of the same day, and flew to the two satellite launch centers of Jiuquan and Xichang, and Zhang Wenhao's BBJ-2 business plane flew directly to the Jiuquan launch center.

When we arrived in Jiuquan, a Long March-3A carrier rocket had already been erected on the launch stand, and all the other three-stage rockets had been installed except for the satellite fairing, which had not yet been installed.

A satellite launch, in detail, has countless important links, but, roughly speaking, there are only two links, one is the launch stage, and the other is the satellite into orbit.

Take the Long March-3A launch vehicle as an example, the structure of the three-stage rocket makes each stage an independent working unit, and each stage rocket has its own task, pushing the rocket to a fixed height, then disintegrating and igniting the next stage of the rocket until it finally reaches the predetermined orbital altitude, and then the satellite fairing opens to release the satellite.

The satellite is successfully released in the predetermined orbit, the launch link is successfully completed, the rest is the satellite's orbit and joint commissioning, the satellite reaches the orbit, must be in the orbit to unfold the solar panels, which is the core energy of the satellite in outer space, if the satellite reaches the orbit but can not deploy the solar panels, then the satellite is basically scrapped, and if the satellite reaches the predetermined height and the solar panels have been deployed, the energy problem is guaranteed, but the ground can not be contacted or controlled, which is also a great tragedy, South Koreans often make this kind of mistake, when the satellite is in the sky, they are either unwilling to stop when they reach the orbit, and continue to send the satellite to a higher position, and after sending it up, they lose contact at every turn, and in the end it is completely equivalent to spending a lot of money to send a bunch of scrap metal to the sky.

Tungchen's satellites are all high-end technologies of the future, and the technology is extremely stable and reliable, and for Tungchen, as long as there are no problems with the launch, the success rate is almost 100%. (To be continued.) )
