Chapter 1608 Moon Landing Plan

The transfer orbit between Blue Star and the Moon is a large elliptical orbit. After the probe separates from the rocket and enters this orbit, the probe does not need to accelerate itself. It only needs to fly along the Earth-Moon transfer orbit. It can reach the vicinity of the perigee. After the probe implements braking and deceleration near the perigee, it enters the orbit around the moon and can then perform a series of tasks such as subsequent descent, ascent, and return.

According to the information provided by Daxia Aerospace Group to Jiuzhou Technology, just to launch the lunar probe, the rocket flight requires take-off, booster separation, fairing separation, rocket separation, and rocket separation... …wait for 10 flight phases.

Not only that, from the rocket ignition to the separation from the detector, the rocket also needs to perform more than 70 sequential steps and actions. Each action involves a number of key products and key parameters, such as control Commands, unlocking devices, and more.

It is precisely because there are too many key products and parameters involved that when Jiuzhou Technology proposed to establish the Lunar Development Science and Technology Association, many people within the Daxia Aerospace Group felt that Jiuzhou Technology was a bit "arrogant" ".

After all, although everyone admits that Jiuzhou Technology is very powerful in the field of technology manufacturing, in the field of aerospace, Jiuzhou Technology is still too "young". With the aerospace technology and data mastered within the Daxia Aerospace Group, as long as they are willing, they can immediately The Lunar Development Science and Technology Association has a very high right to speak.

It is just that this technical association has not yet generated any income and value, so everyone regards it as a project docking organization established by Jiuzhou Technology.

However, one thing that makes all the aerospace personnel of Jiuzhou Technology feel heart-warming is that among the data that Daxia Aerospace Group half donated and half cooperated with, although some of them did not give specific data due to confidentiality rights, as long as It was a project that gave out specific data. There was no fraud or any trap deliberately set in it.

Perhaps it is because the engineers of Polar Bear had similar misdeeds in the past, so when communicating, the older engineers of Daxia Aerospace Group would also say in a serious tone: "Is there anything you don't understand?" , as long as it doesn't violate the relevant regulations, just take the initiative to ask us. Family, don’t talk about two things.”

It is in this atmosphere of sincere cooperation that Kyushu Technology’s aerospace projects can progress so quickly. Otherwise, every important project needs to be done in various ways. Detection and data collection not only waste time, but also waste a lot of manpower and material resources.

When Zhang Tianhao, Zhan Kunhu, Zhang Panyang, Li Jian and others learned of Gu Qing's arrival, they did not restrain their discussions like the technical staff of other companies, but continued to interact as before. However, during the interaction, From time to time, they will raise issues to their own bosses, instead of going around in circles like before.

“If we adopt the direct lunar landing method, then we need the rocket thrust to be powerful enough and to have precise enough control capabilities. After all, after the aircraft flies to the moon driven by the rocket, once it enters the lunar orbit, It is necessary to use the braking rocket between the landing legs to achieve a soft landing on the moon

This. The advantage of this plan is that the flight process is simple enough, but it requires a launch vehicle with a large thrust.

If it is a five-stage rocket, the high-thrust stage will have thousands of tons of thrust. The first stage also requires hundreds of tons of thrust, but we must solve the control system, as well as the inherent safety issues and equipment reliability issues of the five-stage rocket model. After all, manned landing on the moon is different from landing on the moon with a probe. If something goes wrong during the launch process, the chance of the astronauts surviving is extremely low."

"The more sophisticated the technology product, the harder it is. It is inevitable that failure problems will occur, but if we do not use multi-stage rockets, the thrust of the rocket cannot be accurately controlled. In order to launch directly from Blue Star to the moon, the rocket's drug load must exceed that of ordinary space launch vehicles. The JZ-404 rocket and its improved rocket are optimized versions of a certain Long March model. Its drug load may be up to It supports about 70% of the total round trip mileage, and the remaining 30%, do we need to add another level?”

"No, the JZ-404's engine is not good enough. It carries a lot of medicine and is prone to various minor problems over a long journey. The reason is that although the energy source and engine are advanced enough, they are not enough to support landing. Monthly round trip." "This doesn't work, that doesn't work, then how do we calculate it? Orbit? NASA does have ideas in this regard. Our Blue Star is a full 384,000 kilometers away from the moon. Even if we have the help of the Zhoutian Star Project, there will definitely be a delay in communication between the ground and the moon.


NASA proposes to use several launch vehicles The arrow sent the spacecraft and the escape rocket loaded with propellant into low-Earth orbit respectively, docked in low-Earth orbit, and the docked lunar landing assembly flew to the moon.

But this also faced a problem, they also faced a problem. There are no suitable rockets available.”

“Forget about NASA. I'm angry, they can't even build a space station. The most we can do is look at their research direction. It's impossible to really follow their ideas. After all, according to the level of technical reserves, in a sense, we have surpassed With NASA, some equipment is completely incomparable.”

"Old Li, what you said makes sense. I think of our former classmates who worked for NASA. A while ago, they wanted to use my channel to find our company to explore the possibility of cooperation in launching spacecraft.

But they were all rejected by me. They don’t even think about it now. There is no mature high-tech manufacturing industry. Just listen to the theory. If we really want to do it, we might as well cooperate with our Jiuzhou Aerospace Group."

Gu Qing was not surprised when he heard this little information. After all, it is impossible for people to change their diversity because of their profession.

He knows that there are similar circles of relationships and channels in academia and finance.

But after listening to several plans, the atmosphere in the conference room suddenly cooled down.

After a relatively young engineer saw that his teacher, several uncles, and several senior executives of the company had all stopped, he mustered up the courage to say: "Why don't we wait for the breakthrough of the rocket branch's project? After all, No matter how many plans we design, in the end we still have to rely on equipment such as rockets and lunar landers. "

But when he finished speaking, an engineer immediately retorted: "If we don't make a plan in advance and wait until then, we will waste a lot of time and resources!"
