I Have a Little Black Hole

In addition to the help of rich experience, the help of various detection equipment and telemetry equipment is also very important to the Infinite Gravity Group.

While the technical test of the launch vehicle and the spacecraft is carried out, the measurement and control communication system in the launch site shall be subject to the joint test of equipment.

First, the joint test of equipment in the field is carried out, and then the joint test is carried out with the measurement and control stations, measurement and control centers, and surveying ship equipment distributed all over the country, even around the world, and on the ocean.

And the measurement and control station and the measurement ship arranged by the Infinite Gravity Group are still under construction and manufacturing. Without the help of the national aerospace department, this launch mission will be delayed for at least 6 months!

Even if the company spends money, the manufacturing and construction time of these things cannot be accelerated much. After all, the construction and manufacture of these things cannot be completed all at once.

Without the help of these measurement and control stations and survey ships, the launch of the rocket would never have been possible. Neither the company nor Lei Tiantang would allow the launch to be delayed for half a year!

Therefore, the cooperation with the national aerospace department has become very necessary. Anyway, for the recyclable rockets currently used by the company, in addition to the use of new materials and new manufacturing processes, the performance of the rockets far exceeds that of the Falcon 9. There are not many technologies that completely explode state-made rockets.

After all, the heritage of a country is not something that a company can easily surpass in just two years, especially in terms of experience.

Just like now, the two laboratory directors and the cooperative leaders sent by the aerospace department are watching the researchers of the Infinite Gravity Group seriously, and they are learning to release the meteorological reconnaissance balloons with the meteorological experts sent by the aerospace department.

If this work is done entirely by the experts of the Infinite Gravity Group, it can definitely be done well in the end. After all, the company also recruits a lot of meteorological experts.

But few of them have the experience of meteorological observation required for rocket launch. If they were asked to do this alone, it would have been impossible to launch a year ago.

Many times, we can see that the launch forecast has been pushed and pushed again and again due to weather. However, it is clear that the weather is clear and no wind. Why is it that the wind is too strong to delay it?

In the process of space launch in all countries in the world, a set of rules called weather launch commit criteria must be strictly followed. This set of rules prescribes various meteorological conditions. If there are no special mission requirements, failure to meet any of them would have to delay the launch of the rocket.

In the space shuttle's mission history, nearly half of delayed launches have been weather-related.

The same is true of my country's manned space launch. During the live broadcast of the launch, Mother Yang will definitely go to interview the weather station in the aerospace city.

The weather station will definitely report the wind speed, wind direction, temperature, humidity, cloud cover and other detailed information, and finally will be summed up in one sentence: The weather conditions can meet the launch requirements, and then we can go to the next step.

It cannot be launched in rainy days. The rocket is composed of many sophisticated electronic instruments and requires a large number of ground radar telemetry signals during the flight.

Lightning can easily lead to short-circuit and failure of electronic instruments. Thunderstorm clouds also greatly interfere with ground telemetry signals, making rocket guidance and control difficult. The powerful energy of lightning strikes can even destroy rockets.

On March 26, 1987, the old American Atlas-Centaur rocket encountered this situation when it launched a US Navy communication satellite worth more than $1 billion.

Just 48 seconds after the launch, strong lightning struck the rocket, many components including the rocket yaw control element failed, the rocket self-detonated in the air, and the mission failed.

And the impact of wind on rocket launch is also very large! The launch of the rocket does not fly straight into the sky. When it reaches a certain height, it starts to turn to meet the orbital inclination requirements of the mission.

During this period, the rocket needs to undergo complex steering and attitude control, and excessive wind speed, or even wind shear that drastically changes the wind speed and direction, will obviously affect the control accuracy.

The so-called missing a tiny bit is a thousand miles away. The rocket in the initial stage requires extremely high control accuracy, so the impact of strong winds on the rocket must be minimized.

The atmosphere of the rocket flight area is a composite of up to 100 kilometers consisting of the troposphere, stratosphere, thermosphere, and ionosphere.

There are different meteorological conditions and wind speeds in each layer, and abnormal wind speeds in any of them will greatly reduce the control of the rocket and even cause the failure of the mission.

Humans live at the bottom of the troposphere, but the winds felt here are not at all representative of the upper atmosphere. The understanding of the latter requires a combination of professional launch site meteorological observation stations, sounding balloons, meteorological satellites and other factors to detect.

In this regard, the Infinite Gravity Group can be said to have almost no experience. Without the help of the national aerospace department, it would take a long time for the company to explore on its own.

Director Liu, we would like to thank you for your full support to our company! Without the equipment and personnel you support, our company would have to wait at least half a year to launch a rocket! Zhang Hanxiu sighed and stood beside him. Liu Jingwen, head of the aerospace department, said.

Haha! Director Zhang, I don't agree with you saying that, our aerospace department has received a lot of help from your company!

Your company's 100,000-ton die forging hydraulic press alone has helped us a lot. The overall strength of our rockets has all been improved qualitatively, which is much better than the 80,000-ton hydraulic press we used before!

Moreover, the forging tasks given to us by your company are the highest priority, and there is no need to queue for a long time as before, which makes our department very grateful.

You must know that the production tasks of these large die forging hydraulic presses can even be scheduled for a year later, and each task is a very important task.

The country needs it, and some companies also need it, so before we wanted to use such a big guy in advance, it took a long time to report and coordinate.

Now that you have the big man in your company, it really provides us with so much convenience!

And the various high-performance materials that your company has provided us has also given us more margin in the design of our rockets, allowing our rockets to be designed more advanced.

Not to mention that your company has also shared the current technology of recyclable rockets with our department. Of course, our department must attach great importance to such technical cooperation!

Therefore, we can provide help to your company, and our aerospace department is also very happy. By working together, our country's rocket technology can progress faster! Liu Jingwen said with a smile.
