Military Technology

　　 "Have an idea?" Lao Ma's eyes flashed for a moment, and said excitedly.

　　 "Hehe, there are some immature ideas, but these are just ideas. How to implement it depends on the opinions and decisions of the relevant team." Wu Hao said with a smile.

　　 Seeing that Wu Hao was unwilling to say more in this regard, Lao Ma nodded and did not ask any more questions. After all, for such a major core project, no one would confess it at will, and it was still in front of so many people.

　　 As for Brother Xiao Ma, at this time, he was stuck in the needle, and another question was raised: "When can the second-stage rocket body be successfully recovered, that would be too awesome."

　　 Wu Hao smiled and said, "The second-level rocket probably stands at about 20-25% of the cost of the entire rocket, which is not a high proportion.

　　 And the recovery of the second-level rocket is more difficult, because the second-level rocket has already rushed out of the atmosphere, and it is no less difficult than the current manned spacecraft to return to the atmosphere and achieve a safe landing.

　　There are so many reasons, no company has implemented this technology yet. However, many similar ideas and plans have been put forward, and many of them have constructive opinions and ideas.

　　 For example, an expert put forward an eye-catching plan, refer to Musk's interstellar spacecraft structure plan. The two-stage rocket body of the rocket and the fairing part of the load compartment are joined together to design an aircraft that can be reused many times, or the body of the rocket, to perform tasks.

　　The expert’s proposal is to design the second-stage rocket body and load compartment fairing to resemble a space shuttle or X37B.

　　 Relying on the retractable first-stage rocket body to send the aircraft to the critical space altitude, and then the aircraft engine starts to fly to the target orbit for on-orbit flight.

　　 During the orbit flight, it can perform a variety of missions, and its functions are similar to those of the space shuttle, such as releasing satellites from the aviator’s payload bay, etc.

　　 After completing the mission in orbit, the aircraft will return to the atmosphere and use the wings on both sides to glide, then open the landing gear and land on the scheduled runway.

　　 In this way, the entire rocket part can be reused, the cost will be further reduced, and the executable tasks are also very diverse. "

　　 "A great idea, if it can be realized, may become an important means of transportation for humans to go to space in the future. Its significance must not be the same as that of human inventing the passenger plane." Lao Ma praised.

　　 As for Brother Xiao Ma, he looked at Wu Hao and asked, "Has this project been approved?"

　　 Wu Hao shook his head: "Not yet, the preliminary technical demonstration work is in progress."

　　 "Oh, is there any question?" Old Ma asked involuntarily.

　　 "The problem is very big. This is a brand-new structural method. There are a series of problems that need to be solved." Wu Hao said with a helpless expression.

　　 Although he said so, in fact this project has already started, and the project code is "Space Bus".

　　 From the project code point of view, the name "Space Bus" is to hope that this aircraft can send more people and payloads into space like a bus, and become a bridge and ladder connecting space and the earth.

　　 Although the project was established, as Wu Hao said, the difficulties and problems encountered were particularly large and the differences were relatively large.

　　 Some technical experts believe that we should design and develop the ‘Space Bus’ spacecraft based on our mature Jianmu-1 or Jianmu-2 first-stage rocket.

　　 The advantage of this is that it is robust, there are many mature technologies to learn from, and the R&D investment is relatively small. As for the shortcomings, it is naturally also obvious. Whether it is Jianmu 1 or 2, the carrying capacity is very limited, and it is difficult to transport an overweight spacecraft to the sky, let alone a load.

　　 Moreover, the diameter of the rocket body is limited, and the volume of the aircraft that can be carried is also very limited, so the use of this type of aircraft is very limited.

　　 Therefore, some experts believe that we can not be limited to our own rockets, but can design and manufacture ‘space buses’ space vehicles that can be mounted on other rockets.

　　 For example, the Long 5 rocket, which has gradually matured, has a large enough diameter of the first-stage rocket body and a booster to transport heavier loads. Based on this, then the project team can develop and manufacture an aircraft about the size of a real bus. In this way, whether it is carrying objects or manned, the purpose is very obvious.

　　 This plan is naturally very good, but it also has shortcomings. First of all, the investment in research and development. The research and development costs of such a large spacecraft are beyond estimation.

　　 Next is the technical difficulty. No matter the load or volume is not a large amount, the difficulty will increase exponentially.

　　 So this expert worried that it would be too risky to invest in such a huge project all at once.

　　 Finally, after intense discussions and combining everyone’s opinions, Wu Hao finally made the decision to first invest in research and development of small and medium-sized spacecraft that can be launched on Jianmu 1 and 2.

　　After the subsequent technologies are verified and mature, these technologies will be applied to larger-scale spacecraft.

　　 And after the technology of this kind of spacecraft becomes mature, then this kind of spacecraft will have huge advantages in the exploration and flight of alien planets.

　　 Of course, UU reading www. Uukanshu.com For Wu Hao and others, whether it is a large space vehicle or a small space vehicle, if it is successfully developed, history will be written.

At this time, Zhou Xiangming, who came out of the cordon at the scene, walked towards Wu Hao and the others with joy and said: “From the preliminary inspections on the scene, the landing and landing of the rocket's first-level rocket is very successful. good.

In the next step, we will transport the first-level body of this rocket to the factory, and conduct a careful inspection. After confirming that there is no problem, the first-level body of the rocket will be refilled with parachutes and refueled. Then a second launch. "

　　 "Great, everyone's hard work is finally in vain." Let's announce to everyone, they are also waiting. Wu Hao said with a smile.

　　 Yu Chengwu nodded when he heard the words, and then walked to the reporters.

　　 At this moment, the Internet has been dominated by news of this rocket. Basically all domestic media reported this incident on their front page.

　　A group of aerospace and military enthusiasts are very excited, and even many people have begun to ask if there are any related models.

　　 For more ordinary people, the multiple firsts and honors of this launch also make these ordinary people very happy.

　　 After all, such a competitive project, in such a format and environment, is really commendable and commendable.
