Chapter 786

Dongfeng Aerospace City, Western Han Dynasty.

Surrounded by deserts and Gobi, it looks like a barren scene. However, the space city is just in an oasis in the desert. It is close to the mountain in the West and the river in the East. It was a geomantic treasure land selected by Nie Shuai in those years.

This is the satellite launch base of Han and the largest space city of Han.

As the earliest and largest satellite launch center built by Han, it is also a comprehensive launch site for various types of launch vehicles and sounding meteorological rockets. It has complete and reliable launch facilities and can launch medium and low orbit satellites with large inclination. Later, it is also the only manned space launch site.

If you want to be a launch base, of course, it has its unique advantages. It has an inland and desert climate, flat terrain, sparsely populated, little rain throughout the year and long daytime. About 300 days a year can be used for launch tests.

It can be said that you don't have to wait for any launch window, just call if you want.

At the same time, inland, it can make full use of the land aerospace measurement and control network thousands of kilometers from east to west. It has been more than 20 years since it was established in 1958. The living facilities of the whole base are basically complete, and the supporting facilities such as technical support, measurement and control communication, railway transportation, power generation and distribution are perfect. The conditions are very suitable for the launch of satellites and manned space vehicles.

Now, the atmosphere in Dongfeng aerospace city is very tense. Just outside the launch pad, a carrier rocket is preparing for launch.

The launch vehicle looks like a jujube core. It is sharp and long. It thickens from top to bottom. The whole launch vehicle is white. At this time, the five storey console above is slowly releasing.

"After fuel filling, the last self-test begins."

The 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 filling fuel, the rocket has entered an irreversible process of launch.

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 bullet body self-test is normal."

"Engine OK."

As the voices came, the atmosphere at the launch site became more tense, and the launch of the launch vehicle was in front of us.

"Five minute countdown to launch."

Orders are constantly conveyed.

There is a huge clock hanging in front. It's five minutes to ten o'clock.

"Three minute countdown."

"One minute countdown."

In the control Hall of the launch site, the countdown has begun. When the count from ten to zero, a password for ignition came

The operator's hand pressed on the ignition button.

In an instant, the missile standing outside, with four engines below, emitted a thick white smoke.

When unsymmetrical dimethylhydrazine and nitrous oxide are mixed into the engine combustion chamber, they have begun to volatilize. Then, the white smoke suddenly becomes a hot flame. The ignition is successful!

The four engines began to burn hot. The launch vehicle stayed on the ground launch pad for one second, and the missile body was buzzing. Then, the launch vehicle began to rise.

At the beginning, it didn't climb slowly, and the naked eye could follow it, but as it continued to accelerate, it finally became faster and faster.

Thick smoke shrouded the whole launch pad, and nothing could be seen. Only the hot flame was seen above the thick smoke, and the milky white rocket was in the upper part of the flame. The rocket was climbing rapidly towards the sky, and then disappeared into everyone's sight, leaving only the burning flame.

"Launch succeeded!"

Suddenly, the base was boiling.

Of course, only the successful ignition is not a successful launch. After continuing to climb up, exciting news came out one after another.

"The first stage rocket falls off normally."

"Two stage ignition succeeded." this launch vehicle is a two-stage rocket, and the engine is newly designed. At this time, when the two-stage rocket has been successfully ignited, it indicates that the launch is basically close to success.

At this time, the launch vehicle has begun to turn and fly towards the eastern space. The measurement and control sub stations in the east of Dongfeng aerospace city continue to send good news to the flight control center in the launch site area. The horn kept shouting: "good tracking!" "normal operation!" "normal flight!"

Finally, the launch vehicle left the land and entered the sea. The ground measurement and control station could not find its trace. The launch vehicle only left the warhead in front and began inertial flight according to the predetermined trajectory.

Yuanwang-1 and yuanwang-2 Space TT & C ships have entered full speed work at this time. The computer system is running at high speed, receiving data from the ground TT & C network and calculating accurate trajectory.

Several huge antennas in the middle of the measurement and control ship also began to stand high and point to the flying direction. For them, tracking once only takes a few minutes, and for these minutes, they have practiced for a long time.

At the same time, the salvage ship began to be ready.

"Push the helicopter!"

With the order, in the helicopter hangar of the salvage ship, the Super Hornet helicopter has been pushed out. LV Yunxing dressed up and waited for orders on the deck.

From them, you can see the warships of yangbei country not far away.

Yangbei's warships and salvage ships have been crowded out. 18 Han warships have surrounded the city and firmly controlled their splash area.

However, when sailing at sea, the distance between ships is very large. At the same time, there are still risks due to the salvage by helicopter.

For example, right now, on their side, there is a yangbeiguo salvage ship in place outside. When they see their helicopter pushed out, the helicopter of yangbeiguo salvage ship has also been pushed out.

The Chinese crew, standing by the side of the helicopter, stood upright. In contrast, the people in yangbei country were much more free and easy.

Now, the peace ocean is quite hot, and these pilots are also very afraid of heat. They don't pay attention to their clothes at all. In order to cool, they take off the upper part of their one-piece flight suit and hang below their navel.

"Get on the plane!"

With the order from the superior, LV Yunxing and other crew members stepped on the helicopter and sat in their own position.

Seen by foreign pilots from a distance, those guys quickly put on their one-piece flight suits and entered the cockpit. Then, they saw their propeller turning.

How fast they move!

LV Yunxing couldn't help laughing in his heart. He turned on all the switches to prepare for takeoff. However, the engine on the top didn't rotate all the time.

It's half an hour to prepare. It's still early to take off!
