Vol 2 Chapter 836: unbelievable!

Sriharikota launch site is the most important space launch center of the three countries. The Sriharikota launch site covers an area of ​​145 square kilometers and covers 27 kilometers of coastline.
The launch site has test, assembly and launch facilities for large-scale multi-stage rockets and satellite launch vehicles, as well as satellite tracking, telemetry and communication stations for the three countries. Sange's space agency also expanded its solid booster factory here to produce large-size propellant grains for multi-stage rocket engines.
According to the news released by the Sange Space Administration, this latest polar-orbiting satellite carrier rocket is 44 meters tall, slightly shorter than the H-2B and China Long March 3B rockets.
This latest type of polar-orbiting satellite launch vehicle is still a four-section rocket, which has the same solid and liquid fuel system as the previous rocket.
The first section is a solid-state propellant rocket with 138 tons of fuel (HTPB), a diameter of 2.8 meters, and the shell is made of horse nail steel; the second section of fuel is injected into two aluminum alloy tanks, and the fuel is dioxide tetroxide Nitrogen and hydrazine, weighing 41.5 tons, also use asphalt to prevent rolling;
The third section has seven tons of fuel, uses solid propellant (HTPB), uses low-angle nozzles and gyroscopes (within +2 to -2 degrees) made of Kellaf synthetic fibers to control deviation;
The fourth section of the polar-orbiting satellite launch vehicle is designed with two engines and uses liquid propellant (methylhydrazine/nitrogen oxide can release oxygen liquid). The polar-orbiting satellite launch vehicle is controlled by the reaction control system.
The shell of the payload is made of carbon nano-fiber tubes and can send satellites to geosynchronous orbit, but the 130 satellites they will launch this time are all low-orbit satellites.
Due to some improvements in the design, the low-orbit payload of this latest machine-orbited launch vehicle has increased from a little more than 3.2 tons before to 4.2 tons now. It is with this increase in load that they have confidence to come. Launch 130 satellites at once.
Although the largest mass of these satellites is only 230 kilograms and the smallest weight is only 25 kilograms, there are 4 large satellites, and the rest are small satellites. These satellites will form a satellite network in orbit for mobile phone users in the three countries. To provide high-speed Internet services, people don’t have money and nowhere to spend. The hype is just the hype.
This launch has the mentality of watching the excitement. There are still many media in many countries that live broadcast this launch. The current 5G high-speed network also makes ultra-clear live broadcast a normal news broadcast mode. Everyone Also love to watch such content.
"My God! It's really hard to believe that the third brother's launch base is so backward. Look at the equipment here. Compared with our company's'Gaia' launch base, it is almost two eras away!" Infinite Gravity Group sent An employee complained while visiting.
"You can't say that. Not only does our company have a latecomer advantage, but the investment in building a launch base has to exceed this base several times, so the difference is understandable."
"Hi! If your focus is placed on the surrounding environment, the difference will be more visible. It is hard to imagine that they can assemble the rocket and satellite in such a poor sanitary condition!"
"The national conditions are like this! Not a black man! We are going to the control center, and it seems that the launch is about to begin!"
After following the visiting troops to their control center, the countdown to launch was about to enter, and everyone was chatting quietly while waiting for the final moment to come.
However, people sent by various countries and some private space companies were obviously absent. Everyone paid little attention to this launch, because even the third brother’s space agency emphatically promoted this latest polar orbiting launch vehicle. But everyone is in this business, and they are very disdainful of the performance of this rocket.
Because such rocket data really can’t say how advanced it is. Compared with the current mainstream rockets in the world, its performance is not superior in any way, let alone the infinite gravity that now occupies the leading position. Compared with the group, I don’t know where their confidence is better than others.
And although the number of satellites launched this time has reached 130, 126 of them are all small satellites of the same type, and they are still deployed at the same orbital height. This difficulty in launching is also difficult to make everyone interested.
The main reason why I came here was to give the three countries a face, and also to be able to discuss some cooperation intentions in the exchanges of so many peers, so now everyone sits down and exchanges enthusiastically with the peers next to them.
In such an atmosphere, with the iconic curry-flavored English countdown, the rocket successfully ignited into the air. 4 of the 6 bundled auxiliary thrusters and the first section of the rocket ignited with a huge roar and began to rise. empty!
After 25 seconds, the remaining two boosters were successfully ignited~EbookFREE.me~ and continued to provide lift for the rocket. After completing the mission, all auxiliary thrusters were also successfully separated.
As time passed by one minute and one second, the entire rocket's flight was also very smooth. The first, second and third rockets, including the fairing, were all successfully separated.
The rocket was also successfully ignited in the fourth quarter, pushing the satellite to the predetermined orbit. At this point, it is reasonable to say that the basic problem is not big, but this is reasonable.
The third brother staff in the control center all smiled and prepared for the final celebration, at this moment an accident happened!
In the fourth quarter, after the rocket pushed all the satellites to the predetermined orbit, the satellites on it were not successfully separated!
Just when the staff in the control hall changed their faces and were nervously looking for the cause, something that caused them to collapse even more happened. I don’t know why, the remaining four rockets in the fourth quarter had to give the 4 large-mass satellites higher. Some of the fuel for orbital propulsion suddenly leaked!
Just 2 seconds after the white fuel leaked, a violent explosion occurred. The last picture seen by the control center was the explosion picture from the camera on the rocket in the fourth quarter!
The most critical trembling failure made the staff who control the hall directly dumbfounded. Many people covered their eyes in disbelief. The visitors also stood up in surprise. No one thought they had reached this point. Can go wrong!
We must know that in everyone’s perception, since the space agency of the three countries dares to openly invite so many colleagues and the media to visit and report on this launch mission, it must have 100% confidence in this launch. Yes, otherwise, wouldn't it be a loss of adults!
