NetEase science and technology Cui Yuxian When SpaceX launched the most powerful spaceship since the Apollo era - the hawk heavy rocket since the beginning of this year, CEO Zhang Changwu, a domestic private rocket research and manufacturing enterprise, warned that, on the one hand, SpaceX detonated global attention to commercial space and was a strong stimulus to global commercial space; on the other hand, it was in the middle of the world. Chinas commercial space is a reflection and reference signal. In just 12 years, a purely commercial enterprise can achieve such remarkable achievements. The blue arrow, the third worlds third (and two other SpaceX and BlueOrigin) with liquid oxygen methane rocket engine technology, has also accelerated the thrust chamber test of the 80 ton level liquid oxygen methane engine, which would probably be the largest liquid oxygen methane engine in the world if successful in 2019. Industry enterprises. In addition, the intelligent manufacturing base of blue arrow launch vehicle was put into operation in the first half of this year, and carried out digitalization, intellectualization and general management and transformation. Zhang Chang owes his companys rapid development to the environment of Chinas commercial aerospace industry. Zhang Changwu said that Chinas commercial space power has been developing rapidly from the commercial icebreaking in 2015. First of all, it pointed out the direction from the state policy of the system and encouraged all kinds of capital to participate in the space satellite launch field. Secondly, more and more participants in commercial space, especially the enterprises of satellite development and satellite operation, have already had dozens of enterprises; third, there are some enterprises including central enterprises at the capital level. The industry has been involved in the process of setting up new institutions. Therefore, Chinas commercial space will usher in spring in 2018. For the blue arrow in the industrial chain, there are not many competitors on the R & D track, because the technical threshold of this track is very high. Zhang Changwu said that liquid oxygen methane is the core technology of blue arrow, and it is an independently controllable technology. At present, there are only SpaceX in the world and BlueOrigin and other engines that are developing liquid oxygen methane. Blue arrow is the worlds third commercial enterprises to grasp the technology of liquid oxygen methane engine development. Therefore, the blue arrow not only outputs the liquid engine system, but also outputs the carrier rocket. Speaking of the vision of the company in the future, Zhang Changwu used a very simple sentence: to become a world-class commercial aerospace enterprise like SpaceX or Boeing. The following is a part of NetEases technology interview with Zhang Changwu CEO. Chinas commercial space is in the best times NetEase Technology: blue arrow was founded in 2015, when it was just the so-called commercial space ice breaking year, I think everyone said so. After all these years of development, what changes and developments do you have in our commercial space? Zhang Changwu: the changes in the two years are very big. This change is greatly reflected in several aspects. One is from the level of national policy. The relevant authorities have pointed out some directions to the industry in succession. In December 27th of 2016, the national defense Bureau, the national defense Bureau and the China Space Administrations press conference, made clear the direction of national policy in this field, which is to encourage all kinds of domestic capital to participate in the field of space and satellite launch. This is a very important progress. The other sign is that there are more and more participants in the industry for two years. We can see that we are still a little less in the business of launch vehicle development. At the level of satellite development and satellite operation, dozens of enterprises have been carrying out various kinds of enterprises at home. For satellite manufacturing, satellite application is such an undertaking. In addition to a lot of advantages, very mature enterprise units, now or in transition, or to join the layout of the commercial space, I think these are a very big change in the two years, the more the participants. Including capital level, including R & D product mode level. Because many of the capital level including central enterprises, now in the commercial space, rocket or satellite fields have the layout, from the original system of space development units, also set up a lot of new institutions, or companies, platforms, to layout commercial space. NetEase Technology: is there any data support? Zhang Changwu: now, for example, by the earth orbit satellite constellation, by 2020 there are more than 6000 satellites, and the satellites of the earth orbit constellation need to be launched. Of course, nearly 50% of them are American satellites, and this part may still stay in the United States to launch, and the United States will operate in the future. At a stage. But the rest of this is our future commercial space, whether it is a commercial satellite, or a commercial launch, a market that can be touched, and the whole market is more than $10 billion. I think these are the cities that we can reach and get enough to get enough. Field opportunities. Compared with foreign countries, Chinas commercial space gap has further expanded. NetEase Technology: what is the gap between Chinas commercial space and foreign countries? Zhang Changwu: actually, compared with Chinas current commercial space and the worlds commercial space, we are a relatively fast moving country. On the one hand, the foundation of our national space is very solid, we are very independent, from our domestic talents, to our industrial system, space ability is very strong. But the gap, I think there are two aspects, one is that we look at a gap in the field of rocket, I think this gap is now in a process of enlarging. Europe and the United States go ahead, especially in the United States. I think this is brought about by openness, or a guide. From 2010 to this year, the United States has been enacting its new space strategy. It has been consciously enhancing their folk forces to participate in the space construction, including the commercial launch area, which has always been in the direction of a new generation of commercial launches in the United States. These include SpaceX and small and medium-sized commercial rocket companies that are overseas in the US and the US. Such a capacity-building has a big push and direction in the country, and it has also led to a direct result that in the past ten years, we have compared our commercial launch capabilities to the United States, or the entire launch capacity, and that our gap is in fact further expanding than the ability to launch business. But I think our domestic commercial space force is in fact very fast, especially in commercial satellite, commercial satellite operation field, relying on a very good foundation, this two years also have a good development. Whether it is a rocket or a satellite, it still faces a problem, that is, how to be more open, and let our domestic business enterprises stand on the same starting line, on the same track, and compete with other international companies, which is a problem we need to face. It is the space enterprise that we do not lose to the other countries in the world technically, but on the system guarantee, in the degree of openness, in the industry admittance and industry standard, how can we reach a state of orderly and healthy development of the industry as soon as possible, this is our domestic supervision Units, or participants from the industry, have to consider a problem. NetEase science and technology: I saw a news today that the United States now has a competition, saying that the defense bureau is asking these rockets to play, and that the time for the launch of the rocket has changed from a few years to a few days. Is that possible? Zhang Changwu: This is very possible. I think the whole technology of human being entering space, including ability, is changing rapidly and developing very fast. In the process, there are not only new models but also new technologies. But looking back, it is a growth of capacity that has been spawned by openness. Technology driven blue arrow to become a similar SpaceX enterprise NetEase science and technology: as a start-up enterprise, will blue arrow have financial and financing pressure? Zhang Changwu: we must also face the common problems of the entrepreneurial enterprises, whether it is the commercial rocket field or other areas. In the process of entrepreneurship, there may be a considerable period of funding support in a considerable period of time. But from the space such as a special track, I think it is also a strong technical guidance of such a entrepreneurial track, on this track, in fact, as long as it can solve its core technology, core competitiveness, in the current domestic whole environment, we still enjoy the whole country. The rapid development of the economy has brought a convenience. In the whole world, we may have such a good environment for China to develop commercial space in addition to the United States. On the one hand, we have people, on the other hand, we have an industrial system, and we have a more powerful capital market all over the world. NetEase Technology: Blue Arrows vision, what products are landing now? Zhang Changwu: our vision is to become a world-class commercial aerospace enterprise. Companies like SpaceX or Boeing. NetEase Technology: what products can be applied to the floor now? Zhang Changwu: at the beginning of the second half of last year to the beginning of this year, the liquid oxygen methane engine completed a series of more than ten hot tests, that is, the experiment of the ignition test, a systematic test and evaluation of the technology of our teams liquid oxygen methane space engine, and the feasibility of our technical scheme. The feasibility of the art route and the completeness of our entire supply chain system. We have the prototype, and in the second half of this year, our full size 80 ton level of the liquid oxygen methane engine will put into production, so this year our core task is to ensure that our liquid oxygen methane engine can be in a fixed state. NetEase science and technology: I know this technology is still a very leading technology, I do not know how long this technology is the leading opponent, or what are our competitors at home at home? Zhang Changwu: liquid oxygen methane is a very unique technology that can be controlled by our technology core in the process of our whole enterprise development. Liquid oxygen methane is not a new propellant in the history of the launch vehicle, but in the last few years, because we have a higher expectation and pursuit of the reusable launch vehicle, we have come back to see if there is a better propellant, better than the liquid oxygen kerosene, better than the liquid oxygen. Liquid hydrogen liquid oxygen, including our traditional toxic propellant medium, can serve the future repeatable and then focus on liquid oxygen methane. At present, there are only SpaceX and BlueOrigin in the world. We are the third commercial enterprises in the world to master the technology of liquid oxygen methane engine development. If our 80 ton engine is successfully carried out this year, next year it will probably be the worlds largest commercial company with liquid oxygen methane engine. Of course, in 2020, the more large-scale SpaceX engines will come out in 2020, but in general, the liquid oxygen methane engine ensures a core competitiveness in the system. For the time being, we are still competing in the international market. NetEase Technology: you just said that there will be products launched in the second half of this year. What are the users we are facing? Zhang Changwu: our user oriented, launch vehicle as a carrier, the only object it serves is the users of satellite launch needs. So in the future, our users will also include the international and domestic users who need this kind of commercial satellite launch. Of course, our liquid engine itself as a product sequence will also become a core product line of our company. In the future, no matter at home and abroad, some power systems needed on launch vehicles will become a service target for us. NetEase science and technology: so we are both the upstream of the industrial chain and the link of rocket development. Zhang Changwu: Yes, we export both the liquid engine system and the launch vehicle. NetEase Technology: just listen to you, more is a technology driven enterprise. If a commercial rocket enterprise wants to succeed, it needs more technical reserves. Zhang Changwu: I think the only prerequisite is that it can guarantee that the enterprise can survive in this field, and the long-term development is technology. If I go back to the technology of carrier rocket, I think we need to have our own power system or our own liquid power system. Because from the inherent properties of the launch vehicle, including the accepted choice of business space, only the liquid power system can support commercial space and commercial rocket development, because liquid has a good expansibility on the one hand, and the technical barriers that can be set up in this process are also deeper. In terms of control and safety in the field, the liquid is also a choice, including compliance with international conventions. So how to master a unique competitiveness of the liquid engine system, this is the most core, the most fundamental guarantee of the competitiveness of the launch vehicle enterprise. NetEase Technology: are there many commercial enterprises for launch vehicles? Zhang Changwu: I think there are not more than five commercial enterprises in the world who really master the power system of liquid engine. In the future, in the future competition, the field is a subdivision of the field, in the future, in the future, whether the state-owned enterprises or the state-owned competitive market, or the commercial competition market, is actually a small number of participants, 20% of the participants can get a market share of 80%. Such a situation. NetEase Technology: so is it a relatively high technology threshold? Zhang Changwu: Yes. Zhang Changwu: one of our own core milestones, I think it is our own liquid oxygen methane engine, 10 ton scale contraction, a series of ignition tests, very successful implementation. In fact, the future is not only a core milestone for our own own enterprise development, but also a very core milestone in the future of the commercial rocket field throughout the country. Because it opened a window. In the future, along this technical line, the output of our series of power systems will guarantee a guarantee of the continuous power of our domestic commercial space. But in this process we must have encountered many difficulties, in the early stage of our own technical lines are constantly iterating, constantly reaware of a process. Including the first blue arrow to try, whether we can use solid rocket, faster to verify their ability, with solid rockets can open the situation in this market in the early stage. But also after more than a year of exploration, we feel that on the one hand, we are still to take the worlds most mainstream commercial carrier rocket enterprises a technical line, to be able to bid for the worlds first-class launch vehicle enterprises, including SpaceX. In addition, we are also in the process of development, the whole external environment, in fact, is also changing, including the future of the national team for the commercial market of small solid launch vehicles, in constant force, constantly to have new milestones, and in turn, to further the trend of the whole market, We have a new understanding of our own position, I think in this process, it can be said to have encountered many difficulties, but also can be said to be a lot of opportunities to press us to iterate our own cognition.
