Chapter 931: Group Anxiety Before Launch

Among the meteorological factors that affect rocket launch, the most influential one should be wind speed. If the wind speed is too high, it will affect the flight attitude of the rocket, causing the rocket flight to deviate and even cause the launch to fail. Even if you are lucky and the launch is successful,

Satellites and other payloads may be transported to the wrong orbit.

Such consequences may range from satellite function failure, or failure to achieve expected goals, reduced lifespan, etc. To serious consequences, the satellite may collide with other orbiting satellites or spacecraft due to incorrect transportation orbits, which may cause a chain reaction and cause

lead to serious consequences.

The weather forecast system will give relatively accurate forecasts for major weather conditions, but the special microclimate or small air circulation formed in the area, which is what we call gusty weather, is difficult to predict accurately.

Especially in this sparsely populated and vast desert, the meteorological department has relatively few weather stations, so it is difficult to capture the weather conditions in this area.

As for sand and dust, it can be said to be the number one enemy of many precision equipment. Tiny particles in the sand and dust may enter the precision equipment in the rocket body, causing some sensors to fail, or some precision instruments to short-circuit and malfunction, etc.

In comparison, the impact of low temperature is relatively small. Especially for some "ice arrows", that is, hydrogen and oxygen fuel low-temperature rockets, the impact is relatively small.

However, this type of rocket has been specially designed, so it has no impact.

This time, the second stage of the Jianmu-2 recyclable rocket uses a hydrogen-oxygen engine and hydrogen-oxygen fuel.

The first-level recyclable part is Wu Hao's new mixed liquid fuel. This is a rocket propulsion fuel developed by Wu Hao and others, and has obtained relevant patents. Although this fuel is in a liquid state, it is not a pure liquid.

, on the contrary, it is like thicker milk, thus making the engine thrust greater.

Although the fuel is not affected by low temperatures, some catalysts after the fuel is mixed are not resistant to low temperatures, so if the temperature is too low, it will affect the performance of the rocket.

Therefore, there are certain requirements for the temperature of the launch site, especially the ignition stage before takeoff. During these two days, a cold wave from Siberia passed through, so Yu Chengwu and Zhou Xiangming were worried.

In fact, as early as the establishment of the launch site, Yu Chengwu and Zhou Xiangming planned to establish a meteorological observation system within a radius of several hundred miles.

In the vast and sparsely populated desert, automatic weather observation stations using solar energy or wind energy are set up to collect relevant meteorological information. This meteorological information is then integrated with data from the meteorological system in the nearby area and the national meteorological system, so that it can be more accurate.

Forecast meteorological conditions at the launch site.

At present, this system has been initially built and has played a great role.

But this launch not only requires a launch window, and then successfully launches the rocket into space, but also requires a landing time for the rocket.

Especially when landing, the rocket will release three large deceleration parachutes, which are more sensitive to the influence of meteorological information, especially wind speed.

So until the last moment, Yu Chengwu and Zhou Xiangming had no idea.

When we arrived at the launch site command and control center, it was brightly lit and a busy scene. Compared to the last rocket launch, everyone was obviously busier this time.

Not only because the launch process of this recyclable rocket is more complicated, but also because this is their first recyclable commercial launch vehicle to be officially launched.

This recyclable commercial launch vehicle is technically more difficult, so everyone has no confidence. Therefore, everyone hopes to be foolproof before the rocket is launched to ensure the success of the rocket launch and return.

Especially for all members of the entire project team, what is even more critical is the two satellites carried on the rocket this time. One is a scientific experiment satellite from a certain research institute, and the other is from a commercial company.

Ground-based remote sensing observation satellites.

The value of these two satellites is relatively high. Although they are insured, everyone is still quite uneasy.

After all, this is the first round of cooperation with these institutions and companies. If it fails, although there is insurance to compensate, it will delay the project development process. As a result, it will be more difficult to cooperate in the future.

The second thing that everyone is worried about is that this time not only Wu Hao came to take charge of the event in person, but also invited big celebrities like Lao Ma and Xiao Ma to watch on the spot.

If something goes wrong and the launch fails, it will have a great impact on future projects. Thinking about the days to come, everyone couldn't help but smile bitterly.

Wu Hao walked to his seat and sat down, then waved his hands to Yu Chengwu, Zhou Xiangming and others and said, "Okay, you all go and do your work, don't worry about me, I'll just take a look."

Seeing what Wu Hao said, everyone was not polite and immediately started to get busy. Zhou Xiangming nodded to Yu Chengwu, then said hello to Wu Hao, and hurried to get busy.

Wu Hao looked at Yu Chengwu who was sitting next to him and said, "How are you doing? Are you confident?"

Yu Chengwu smiled and shook his head: "I have confidence, but I'm just not sure."

"What are these words?" Wu Hao laughed after hearing this.

"Recoverable rockets are much more structurally complex than disposable rockets, and there are too many factors that can affect rocket launch. There is definitely no absolute certainty, but we will go all out."

Looking at Yu Chengwu's prematurely aging hair with some gray hair on his temples, Wu Hao smiled and comforted him: "Just work hard, don't put too much pressure on yourself.

I heard that you haven't rested for a long time. After this launch, no matter whether it is successful or not, you should take a good rest for a while and wait until the new year is over."

Yu Chengwu smiled bitterly and shook his head and said: "Success is good, I can rest for a few days. But if it fails, how can I rest peacefully if I don't find out the reason and solve it."

"Don't put so much pressure on yourself." Wu Hao looked at him and advised: "This project cannot be completed in a day or two. There is a long way to go, and you still have many tasks to do. You have to take care of yourself."

"Don't worry, Mr. Wu, a group of us are running and exercising around the base every morning. Our bodies can handle it." Yu Chengwu said with a smile.

"After the launch mission in March is completed, we will take a short break. The weather will also be warm by then, and we can also take a good vacation."

Hearing this, Wu Hao nodded and said with a smile: "That's good. Anyway, you can make your own arrangements and coordinate the relationship between work and life.

Work is important, but life is equally important. Don’t forget life for work.”

"Um, Mr. Wu, I'm afraid you are not qualified to criticize me in this regard. I heard that your longest record was that you were stuck in the laboratory for more than ten days without coming out."

Wu Hao:......
