Chapter 786: Launch vehicle

Dongfeng Aerospace City in the west of Han State.
Surrounded by deserts, the Gobi looks like a barren scene, but this space city happens to be located in an oasis in the desert. It is surrounded by mountains to the west and river to the east. It was a geomantic treasure that Nie Shuai personally selected back then. .
This is the satellite launch base of Han State and the largest space city in Han State.
As the earliest and largest satellite launch center in Han, it is also a comprehensive launch site for various types of carrier rockets and airborne elephant rockets. It has complete and reliable launch facilities and can launch medium- and low-orbit satellites with relatively large inclination angles. In the later period, it is also the only manned space launch site.
If you want to be a launch base, it certainly has its unique advantages. It has an inland and desert climate, flat terrain, sparsely populated, little rain throughout the year, and long daylight hours. There are about 300 days for launch tests each year.
It can be said that you don't have to wait for a launch window, you can just hit it.
At the same time, because it is inland, it can make full use of the land-based aerospace measurement and control network, which has a distance of thousands of kilometers from east to west. It has been established in 1958 and has been more than 20 years now. The entire base has basically complete living facilities, technical support, and measurement and control. Communication, railway transportation, power generation and distribution and other supporting facilities are complete, and the conditions are very suitable for the launch of satellites and manned space vehicles.
Now, the atmosphere inside Dongfeng Aerospace City is very tense. On the launch pad outside, a launch vehicle is preparing to launch.
This launch vehicle looks like a big jujube nucleus. It is pointed and long. It becomes thicker from top to bottom. The entire launch vehicle is white. At this time, the upper five-story console is slowly letting go.
"Fuel filling is complete and the last self-check starts."
This launch vehicle uses liquid power, so it must be filled with fuel in advance. At this time, a chemical defense soldier wearing a gas mask is evacuating from the launch tower. From the moment of refueling, the rocket has entered The irreversible process of launching.
In the control hall not far away, everyone was staring nervously at the big screen.
A famous operator kept reporting.
"Program injection is normal."
"The self-check of the projectile is normal."
"The engine is normal."
With the sound of one by one, the atmosphere at the launch site became more tense, and the launch of the carrier rocket was right in front of us.
"Five-minute countdown to launch."
One by one, the orders were continuously conveyed.
There was a huge clock hanging in front of it, and it was ten o'clock just five minutes away.
"Three minutes countdown."
"One minute countdown."
In the control hall of the launch site, the countdown has already begun. When it counts from ten to zero, a command to fire is heard.
The operator's hand pressed on the ignition button.
In an instant, the missile standing outside, with four engines below it, emitted a thick white smoke.
Unsymmetrical dimethyl hydrazine and dinitrogen tetroxide have begun to volatilize when they are mixed into the combustion chamber of the engine. Then, the white smoke suddenly turned into a hot flame, and the ignition was successful!
The four engines all began to burn hot. The carrier rocket stayed on the ground launch pad for a second, the projectile hummed, and then the carrier rocket began to rise.
At the beginning, it did not climb slowly, and could be seen with the naked eye, but as it continued to accelerate, it finally got faster and faster.
The thick smoke enveloped the entire launcher, and nothing was visible, except that there was a hot flame on the thick smoke. On the upper part of the flame, there was the milky white rocket. The rocket was rapidly climbing towards the sky. Then, Disappeared in everyone's sight, only the burning firelight remained.
"Successful launch!"
Suddenly, the base boiled.
Of course, just a successful ignition is not considered a successful launch. After continuing to climb upward, exciting news came out one after another.
"The first-stage rocket falls off normally."
"Secondary ignition is successful." This launch vehicle is a second-level rocket with a newly designed engine. At this time, when the second-level rocket has successfully ignited, it indicates that the launch is basically close to success.
At this time, the carrier rocket has begun to turn and fly towards the eastern space. The measurement and control substations in the east of Dongfeng Aerospace City continue to send good news to the flight control center of the launch site, and the horn keeps shouting: "Good tracking!" Working normally!" "Flying normally!"
Finally, the launch vehicle left the land and entered the sea. The measurement and control station on the ground could no longer find its trace. The launch vehicle only had the warhead in front, and started its inertial flight according to the predetermined trajectory.
The Yuanwang-1 and Yuanwang-2 spacecraft measurement and control ships have already entered full-speed work at this time. The computer system is operating at high speed, receiving data from the ground measurement and control network to calculate accurate trajectories.
Several huge antennas in the middle of the measurement and control ship also began to stand up high, pointing to the direction of the flying. For them, tracking once took only a few minutes, and for these few minutes, they had already practiced. long time.
At the same time, the salvage ship is also ready.
"Push the helicopter!"
Following the order, in the helicopter hangar of the salvage ship, the Super Hornet helicopter has been launched. Lu Yunxing is neatly dressed and waiting on the deck.
From them, you can see the warships of Sheepback Country not far away.
Sheep's warships and salvage ships have been squeezed out. The 18 Han warships surrounded the city in a circle, firmly controlling their splash zone.
However, when sailing on the sea, the space between ships is very large. At the same time, there are still risks due to the use of helicopters to salvage.
For example, right now, on their side, there is a Yangbei country salvage ship in place on the periphery. After seeing their helicopters launched, the Yangbei country salvage ship helicopter has also been launched.
The crew of the Han country stood by the side of the helicopter, with a stiff body. In contrast, the people from the Sheep Back country were much more free and easy.
Now, it is quite hot in the Heping Ocean, and these pilots are also very afraid of heat. They don't pay attention to clothing at all. In order to be cool, they took off their full-body flight suits and dropped them below their belly buttons.
"board the plane!"
Following the command from the superior, Lu Yunxing and other crew members boarded the helicopter and sat in their seats.
Seen from afar by foreign pilots, those guys hurriedly put on the one-piece flight suits and entered the cockpit. Then, they saw their propellers spinning.
They are moving so fast!
Lu Yunxing couldn't help but chuckle in his heart, turning on the various switches on his own to prepare for takeoff, but the engine on the top did not spin.
This is half an hour to prepare, it is still early to take off!
