Vol 2 Chapter 504: The importance of cooperation with the national space agency

In addition to the help of rich experience, the help of various detection equipment and telemetry equipment is also very important to Infinite Gravity Group.
While the launch vehicle and spacecraft are undergoing technical testing, the measurement and control communication system in the launch site must be tested for equipment.
First, carry out joint test of equipment in the field, and then joint test with measurement and control stations, measurement and control centers, and measurement ships distributed throughout the country, even the world, and the ocean.
The measurement and control stations and survey ships deployed by Infinite Gravity Group are still under construction and manufacturing. Without the help of the national aerospace department, the launch mission will be delayed at least 6 months later!
Even if the company spends money, the manufacturing and construction time of these things can't be accelerated. After all, the construction and manufacturing 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 be carried out. Neither the company nor Lei Tiantang would allow it to be delayed for half a year before launching!
Therefore, cooperation with the national aerospace department has become very necessary. Anyway, for the company’s current recyclable rockets, in addition to the use of new materials and new manufacturing processes, the performance of the rocket far exceeds the Falcon 9. There is not much technology that can completely explode rockets manufactured by the country.
After all, the foundation of a country cannot be surpassed by a company in just two years of development, especially in terms of experience.
Just like now, the two laboratory directors and the leaders sent by the space department to cooperate are watching the researchers of Infinite Gravity Group carefully, and the meteorological experts sent by the space department are learning to set up weather reconnaissance balloons.
If this work is done entirely by the experts of Infinite Gravity Group, it will definitely be possible in the end. After all, the company also recruits many meteorological experts.
However, few of them have the meteorological observation experience required for rocket launches. If they were to do this alone, it would be impossible to launch them years ago.
In many cases, we can see that the launch forecast is pushed up again and again because of the weather. However, it is clear that the weather is clear and there is no wind. Why is it delayed because of the wind?
In the process of space launches of all countries in the world, they must strictly abide by a set of rules called "weatherlaunchcommitcriteria". This set of rules stipulates various weather conditions. If there are no special mission requirements, the launch of the rocket must be postponed if any of them is not met.
In the mission history of the space shuttle, nearly half of the delayed launches are related to weather factors.
The same is true for my country's manned space launch. During the live broadcast, Yang Ma will definitely interview the weather station of the Space City.
The weather station will definitely report detailed information such as wind speed, wind direction, temperature, humidity, cloud cover, and so on. Finally, it will be summarized in one sentence: "The weather conditions can meet the launch requirements" before proceeding to the next step.
It cannot be launched on rainy days. The rocket is composed of many sophisticated electronic instruments and requires a large number of ground radar telemetry signals during the flight.
Thunder and lightning can easily cause short circuits and failures of electronic instruments. Thunderstorms also greatly interfere with ground telemetry signals, making rocket guidance and control difficult. The powerful energy of lightning can even destroy rockets.
On March 26, 1987, the old American cosmic god-Centaur rocket encountered this situation unfortunately when it launched a US Navy communications satellite worth more than $1 billion.
Only 48 seconds after launch, strong lightning hit the rocket. Many devices including the rocket yaw control components failed. The rocket exploded in the air and the mission failed.
The impact of wind on rocket launch is also very large! The rocket launch does not fly straight to the sky. When it reaches a certain altitude, it starts to turn to meet the mission's orbital inclination requirements.
During this period, the rocket needs to undergo complicated steering and attitude control. Excessive wind speed, even drastic changes in wind speed and wind shear, will obviously affect this control accuracy.
The so-called "to lose a little bit is a thousand miles away", the rocket in the initial stage requires extremely high control accuracy, so it is necessary to minimize the impact of strong winds on the rocket.
The atmosphere in the rocket's flight area is a complex of up to 100 kilometers composed of the troposphere, stratosphere, thermosphere, and ionosphere.
On each floor, there are different weather conditions and wind speeds. Abnormal wind speeds on any of them will cause the rocket control to be greatly compromised and even cause the mission to fail.
Humans live at the bottom of the troposphere, but the wind we feel here cannot represent the high-altitude atmosphere. To understand the latter, it is necessary to integrate professional launch site meteorological observation stations, sounding balloons, meteorological satellites and other factors to detect.
The Infinite Gravity Group has almost no experience in this area. Without the help of the national aerospace department, the company would take a long time to explore it on its own.
"Director Liu, we want 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 the rocket!" Zhang Hanxiu sighed and followed the person standing next to him. Said Liu Jingwen, head of the space department.
"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, much better than the 80,000-ton one used before!
Moreover, the forging tasks given to us by your company are all arranged with the highest priority~EbookFREE.me~ There is no need to queue for a long time as before. For this, our department is very grateful.
You must know that the production tasks of these large die forging hydraulic presses can even be scheduled for one 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 would take a long time to report and coordinate.
Now that you have a big man in your company, it really provides us with too much convenience!
In addition, the various high-performance materials provided by your company also give us a greater margin for our rocket design, allowing our rocket design to be more advanced.
Not to mention that your company has also shared the current technology of recoverable rockets with our department. Of course, our department must attach great importance to such technical cooperation!
Therefore, our aerospace department is very happy to provide help to your company. Only when we cooperate together, can our country's rocket technology advance faster! "Liu Jingwen said with a smile.
