Military Technology

　　 When I wake up, the sky is bright. He covered his head and shook his head again and again. This is the reason why Wu Hao is unwilling to get drunk. Even the best wine, the sequelae of drunkenness is really uncomfortable.

　　 took a shower, washed away the smell of alcohol, changed into clean clothes, and went to the base restaurant for a light breakfast, which gave him some energy.

　　 After inquiring, I learned that Yu Chengwu and Zhou Xiangming had already gotten up a long time ago, and they were already engaged in new jobs.

　　 This morning, they will transport the first-level body of the Jianmu-2 rocket on the landing field to the factory building of the base for careful inspection and research.

　　 Although it was a successful launch and landing recovery, it was a brand new model after all, and the first time it was launched, there must be some shortcomings. These places must be found through careful inspection and then researched and improved.

　　 Strictly speaking, the first-stage body of this rocket can no longer be used for a second launch. However, Yu Chengwu and the others still hope that they can repair and improve as much as possible, so as to carry out a second or even third launch.

　　 Because the more launches, the richer the data that can be collected, which is conducive to the research and development of their related technologies and subsequent projects.

　　 drove to the launch site, it was already a busy scene. A huge crane has arrived on the scene, and the nearly 267-meter first-stage rocket body has been successfully hoisted.

　　The technicians are folding the landing gear, and then transport and load the first-level rocket body onto a special multi-wheel transportation vehicle, and then transport it to the base plant.

　　 Mr. Wu. Seeing Wu Hao's arrival, Yu Chengwu, wearing a white helmet, hurriedly greeted him.

　　 Um, Cheng Wu, I wake up so early, so why don't you take a few more days to rest? Wu Hao asked with a smile.

　　 Yu Chengwu looked at Zhou Xiangming who was directing the operation not far away and said with a smile: "Everyone is so excited that they can't sleep. It feels like a model airplane made out of time and effort when I was a child, and finally the test flight succeeded.

　　 Now everyone wants to transport this big guy back urgently, and then analyze and study it to learn from experience.

　　 To be honest, it is difficult for us to determine whether the success of this launch and landing recovery comes from technical strength or luck.

　　 We don't want to bet our success on illusory luck. We hope that through our own efforts, we can copy this success to the next project and even the next project. "

　　Good, ambitious. Wu Hao showed a relieved look upon hearing this, and this was what he expected to see. It seems that the scientific research team, or Yu Chengwu, and Zhou Xiangming, were not dazzled by a single success. Obviously, they were very lucky. This is worthy of recognition.

Thinking of this, he smiled at Yu Chengwu in front of him and said: "While working hard, we must also pay attention to rest. Our company will combine work and rest. So you discuss with Xiang Ming and give everyone a few more days off. Take a good rest, and the same goes for you."

Hearing Wu Hao’s words, Yu Chengwu showed a look of embarrassment and said: "We try our best to arrange for everyone to rest and rest. I have been a bit busy recently. It will be fine after this period. We will give you a few more days of vacation. Let everyone have a good rest."

　　 Wu Hao nodded when he heard the words, and then said to Yu Chengwu: “Although we tactfully rejected Erma yesterday, I will try my best to satisfy you with the funds and resources that should be given, and add them appropriately, so you don’t have to worry about this.

　　 So at this stage of these projects, you have to do some things to make sure that they can develop healthy and steadily.

　　 Also, you need to pay extra attention. The successful launch and recovery of our rocket this time is bound to bring a wave of aerospace boom in China. These are nothing, but we have to be aware that some companies will use their brains to dig our corners.

　　 So you pay more attention to this aspect to ensure that the personnel of each project team are stable and the progress of the project is not affected. "

　　 Yes, I must pay more attention. Yu Chengwu nodded, his expression dignified. The competition among domestic counterparts is very fierce, and the battle for talent between headhunters is even more famous.

　　 This is also the reason why many large foreign companies are not applicable after they come to China, and they have been complaining about the difficulty of doing domestic business.

　　 Therefore, Wu Hao also gave Yu Chengwu a vaccination in advance to make him pay more attention to this aspect.

After asking this, Wu Hao immediately looked at the huge first-stage rocket body that was being hoisted by a crane and said, "How are the preparations for the rocket that will be launched in March? It has not been a few months. "

　　 After hearing his words, Yu Chengwu immediately got up and replied: "The rocket manufacturing has been completed, and the next step is to test and improve.

　　 Compared with our previous generation of low-cost disposable launch vehicles, we have made many improvements and optimizations on this ultra-low-cost disposable launch vehicle.

　　 not only continues to enhance the rocket’s carrying capacity, but also enhances the reliability of the rocket, especially the emergency handling ability of the rocket after a failure.

　　 In addition, compared with the last low-cost disposable rocket, this ultra-low-cost disposable launch vehicle has also been optimized and improved in cost, which has further reduced the cost.

From the data we have obtained so far, the cost of this ultra-low cost disposable launch vehicle has been greatly increased compared with the previous one, and its cost has been reduced by about 20%. . "

　　 Hearing Yu Chengwu's report, Wu Hao nodded involuntarily, UU reading www.uukanshu.com showed a satisfied look. The technology of this rocket cannot be frozen because of the success of the last launch. Instead, it is still undergoing continuous optimization and improvement to make the performance of the rocket more excellent.

　　Upper level, how is the R&D work going on? Wu Hao said with concern.

　　 The so-called upper stage of a rocket refers to the part above the first stage of a multi-stage rocket, usually the second or third stage. The function of the upper stage is between the launch vehicle and the spacecraft. It has the ability to maneuver in autonomous orbit and has a long flight time in orbit. Generally, it can start ignition multiple times to meet the needs of different launch missions.

　　 can send one or more payloads into the designated orbit, which is vividly called "space bus" or "space shuttle bus".

　　 The biggest function of the upper stage is to send the carried satellites and other payloads to different orbits. This is not new, and ordinary rockets can do it.

　　 In fact, the two rockets launched by Wu Hao before have sent three satellites and two satellites to different orbits.

　　 It's just that it relies on the thrust of the secondary rocket, and then releases the satellite at different altitudes to achieve the ability to transport to different orbits.

　　 And the upper level is more free. Its space shuttle bus, and the elegant name of the space bus, illustrate the problem.

　　 It can transport multiple satellites to different orbits very freely and flexibly, which is impossible for ordinary rockets.
