I Have a Little Black Hole

As a senior executive of the company, Xiong Antai is very pleased with the envy of Academician Yang. He was also attracted by the very good research environment in the company.

Yes, your company has hired dozens of experts and researchers from our aerospace department. If the conditions are not good, how could they jump from the State Key Laboratory to your company!

If it weren't for our cooperative relationship, these experts and researchers would see if we would let them go! Get cheap and sell well! Yang Mingliang looked at Xiong Antai with contempt and said.

Ha ha......

His words also made everyone who heard it burst into laughter. Indeed, people from the aerospace department took a look at the laboratory and workshop here, hey! So many acquaintances!

Everyone was talking and laughing while inspecting the detection and monitoring tasks that the two sides cooperated with. There is less than a week left until the launch day. These tasks are the key to whether the rocket can be launched on time within the window time!

What is the launch window? The launch window refers to the appropriate time range for the launch of the launch vehicle, and the size of this range is also called the width of the launch window. For spacecraft, the choice of launch window is critical.

Although the length of the launch window has a certain time, the effect of launching at the front and rear points of the launch window is different. The launch window will not change under normal circumstances, but it is not absolute. If the weather does not help, the time will be adjusted.

According to various constraints, the launch windows of various satellites also have their own rules. Even if the orbits of different satellites are the same, the launch windows may be quite different.

Generally speaking, due to the long voyage of the rocket launch section when launching a geostationary satellite, the angle between the meridian plane where the launch point is located and the main axis of the transfer orbit is relatively large, and the orbit change operations of the satellite are all performed at the apogee of the transfer orbit.

If the apogee should be in the daytime environment in order to meet the constraints of the sun angle and the sun-earth opening angle, then the launch of the geostationary satellite will be carried out at night. The emission window width is generally about 1 hour.

Academician Yang, based on the current observational data, can we achieve a 'zero window' launch? Although our satellites and space telescopes have enough fuel, we can reduce the fuel they consume when changing orbits. OK!

So that they can stay in space for a little longer, especially space telescopes, our company has not yet mastered the technology to refuel them in space.

For them to be able to provide our company with observational data, the longer they stay in space, the more data we get. Zhang Hanxiu asked with a smile.

To be honest, he was under a lot of pressure during this time. He had to consider the performance of the three satellites and two space telescopes, whether they could work normally after they were launched into space, and how long they could work.

As the person in charge of the Deep Space Laboratory, the pressure these things have brought him has caused him to not sleep well for several days, so it is understandable that he is a little nervous now.

Director Zhang, you don't have to worry so much. According to the data we have observed so far, even if we can't launch a 'zero window' launch, we can launch them into space one by one within the specified launch window!

And your choice to launch in winter is also a very correct choice. There is not much rainfall here in the South Island throughout the winter, and there are not too many tropical cyclones, so there are more choices when the wind speed is suitable for the launch.

These conditions, combined with the rain bomb you applied for, should allow your rocket to be launched within the launch window.

Also, as you said, your carrier rocket technology is really advanced, and its payload is nearly double that of a Falcon 9 of the same size.

This allows your satellites and space telescopes to carry more fuel and equipment.

With the fuel remaining, it is not a big problem even if it is not launched in the 'zero window', so don't be so tense all the time, always so tense, it will also have an adverse effect on the mission! Yang Mingliang smiled and comforted him.

He can understand Zhang Hanxiu's nervousness. After all, this is his first time as a leader to launch a rocket satellite.

Moreover, he still launched 5 payloads in a short period of time that his laboratory was responsible for. It was impossible to make him not nervous, so he could only comfort him.

That said, but I still hope that our rockets can be launched in the special window of 'zero window', so that our satellites and space telescopes can stay in space for a few more months, which will also bring benefits to the company. Come for more benefits! Zhang Hanxiu said with a smile.

The reason why he has always wanted the company's satellites and space telescopes to be launched during the zero window launch period is that this launch window is really the most suitable!

In theory, the rocket lifts off in the launch window and puts the satellite into its intended orbit, all successful. The so-called 'zero window' can be seen as the launch within plus or minus one second of the set launch time.

But generally speaking, the 'zero window' actually has a certain time width, and it is necessary to aim at the front edge of the window to launch. Such a punctual launch will be more efficient when the satellite changes orbit after being sent to orbit, save fuel, and the follow-up work will be smoother.

There is almost no room for adjustment of the launch time of the rocket during the launch of the 'zero window'. Usually, the method of timing control of the rocket ignition is used to achieve the launch of the 'zero window'.

The launch of zero window pursues zero errors, zero errors, zero failures, zero defects, and zero omissions. To achieve zero windows, it is necessary to overcome difficulties.

Rocket launch is a complex system engineering, tens of thousands of sets of equipment need to be checked for faults, risk analysis and operation experiments, and thousands of positions need to be coordinated.

If any piece of equipment fails, any position is negligent, and even if some operators sneezed, the zero window will pass by.

In order to ensure that the rocket can be launched in the zero window, the launch center must carry out guarantee work in accordance with the high standards required by the quality system.

The first is the guarantee of personnel, the second is the guarantee of equipment, the third is the specification of experimental documents for various systems, and the guarantee of various software such as command system software, satellite and rocket software.

Our meteorological system is required to carry out accurate and detailed forecasts of meteorological elements such as lightning, precipitation, temperature, wind and wind direction and cloud cover in the launch window.
