Countdown to four o’clock, another big screen, which broadcast the real-time location of the Hercules rocket, Zhao Huasheng saw a reddish flame at the tail of the Hercules rocket, which was not strong but looked full of power.
This rocket quickly strengthened in just four seconds and finally became a vertical jet. At the same time, the flame of Hercules rocket was strengthened and four boosters were installed. At the same time, the flames of the boosters and the main engine of the rocket blended together and finally became extremely bright, which made people almost look straight.
“！”
"launch!" Wang Tangli roared out the word launch.
At this time, the jet fire from the tail of the Hercules rocket was strengthened again. These flames turned into a color-transparent shape just after leaving the rocket. The gas around them was distorted because of the high temperature. It was said that they were strong and they showed a strong crimson rolling after several meters from the tail of the rocket.
A large amount of white fog transpired at the tail of the rocket, which almost covered dozens of meters in Fiona Fang. Zhao Huasheng knew that it was formed when the flame from mega launch was led out by the diversion tank and then cooled down and the liquid evaporated rapidly.
At this time, even if the distance from the Hercules rocket was less than 1000 meters, Zhao Huasheng felt the earth shaking, which was very slight but very dull, like an earthquake but not quite the same as an earthquake.
Zhao Huasheng looked up and saw from the real-time location screen that the Hercules heavy-duty rocket, which was 70 meters high and weighed more than 4,000 tons, was slowly rising. At one time, it was very slow, just like a rope slowly rising, but after only ten seconds, its speed rose to a height that made people feel a little shocked.
In the extremely rapid acceleration, the gravity of the rocket part is more than ten times that of the earth, which can be seen from the twisted faces of the five astronauts in the flat storage.
Astronauts with such great gravity can’t even raise their arms. They can lie quietly in the warehouse and do their best to fight against this great gravity beyond ordinary people’s imagination.
A large number of things that seem to be fragments are peeled off from the rocket body and splashed on the ground like rain. Zhao Huasheng knows that those fragments are rocket insulation layers, but they are actually some foam plastics.
When the rocket is still on the ground, it is necessary to prevent the low temperature on the ground from affecting the material structure of the rocket body. Engineers have attached these things to the shell of the rocket body. When the rocket rises, it will peel off these plastic foams by violent friction with the atmosphere, which forms the fragments we see at the moment.
There is a constant report in the control hall. Listening to the "normal" and "normal" Zhao Huasheng’s slightly nervous mood has also calmed down.
After the rocket rose for more than 20 seconds, the rocket’s rising direction changed a little. Instead of pointing vertically at the sky, it shifted slightly to the east. Because the earth’s rotation shifted from west to east, it can increase its speed by means of the earth’s rotation.
After more than a minute, the four boosters of the Hercules rocket body were installed and separated from the rocket at the same time. They have done their duty, and it is time to leave. At this moment, the rocket speed is not up to the first cosmic speed of the earth. Those separated boosters will fall to the earth at a very high speed and then be damaged by intense friction with the atmosphere. If the combustion is not sufficient, it is possible that some debris will fall to the ground.
After the booster is separated, it’s time to separate the first-stage engine, so as to ensure a strong driving force. The Hercules rocket has a total of three-stage structure, in which the first-stage engine bears the most important and arduous task, and its volume is also the largest. The total length of the Hercules rocket is 70 meters, and the length of the first-stage engine has reached nearly 30 meters.
The Hercules rocket is still flying at a high speed, but at this moment, the flame at its tail suddenly disappeared for a moment, and the first-class engine crashed away from the rocket for 30 meters. It also fell to the earth like a pre-separated booster, and then disappeared in fierce friction with the atmosphere.
The first-stage engine is separated from the second-stage engine for ignition, and it will bear the burden of sending the rocket into orbit.
It took less than a minute for the second-stage engine igniter to follow the footsteps of the first-stage engine, and it also fell off the rocket and fell into the atmosphere.
At the moment, the Hercules rocket is more than 300 kilometers above the surface of the earth, and it has reached the altitude of low earth orbit, but this altitude is not enough, and it will continue to rise.
The gas here is extremely thin, and the fairing at the tip of the rocket arrow is gone. It was also thrown by the rocket and fell into the atmosphere.
The storage of materials will completely expose the environment, but the storage of materials also has a perfect life support system, which will not affect the astronauts in the warehouse
The third-stage engine was completed after working for more than half a minute, but it will not be thrown off the rocket. At this time, it is necessary to leave the rocket for material storage.
This step is the separation of the ship and the arrow. After the acceleration of the three-stage rocket engine, the material reserve has enough speed. After it has entered the orbit around the earth, it will travel alone.
At this point, the launch has been successful, and the workers in the control hall have recovered from their nervousness. The real-time images of the astronauts are still broadcast on the display screen. Zhao Huasheng saw that the astronauts have escaped from the huge gravity. At this moment, they are in a weightless environment. Zhao Huasheng saw that their cabins floated spontaneously, just like water.
"Finally, nothing happened." Zhao Huasheng breathed a sigh of relief and threw out that ominous premonition in his mind.
The material reserve warehouse also has its own propulsion engines. When the cabin orbit and speed adjustment come, the material reserve warehouse will orbit the earth twice at a speed of 17 minutes, and adjust its attitude, angle and speed during this period, and finally dock with the Red Heart rocket.
Zhao Huasheng has been waiting for the materials to be stored here, where the sun rises and falls, and it rises and falls twice. The figure of the latosolic red heart solar probe spacecraft finally appeared in the field of vision.
The speed of the material reserve warehouse and the spacecraft Chihongxin is 9.3 kilometers per second at the moment, which is incredible high speed, but both of them maintain the same speed, so they look like they are at rest, so they are almost at rest. Finally, the ground workers help to dock and fix the interface smoothly, and the steel claws of the docking are also smoothly extended to firmly connect the two.
Five astronauts came to the control room of the red heart spacecraft from the material storage through the docking interface.
Chapter 31 Busy Equator City
The launching process has come to an end here, and then the Red Heart spacecraft will orbit the earth for about 70 times in three days. During this process, the orbit of the Red Heart spacecraft will become flatter and flatter, and the apogee will get farther and farther, and the perigee will get closer and closer. Eventually, the Red Heart spacecraft will break away from the orbit around the earth and step into the vast space to spend six to six months.
During these three days, five astronauts will help the ground crew to carry out the final test and debugging of the spacecraft. After all, the spacecraft is still in Earth orbit. If there is an accident, it can be repaired by launching a rocket. If there is another accident when you step into the vast space, there is really no way.
Tang Wang introduced to Zhao Huasheng that "the spacecraft uses conventional engine and off-engine power sources". "When it needs to accelerate and decelerate for a short time to adjust its orbit and attitude, it uses conventional engine to fly to the sun, and the spacecraft takes off the engine without too much orbit adjustment".
The power source of high-temperature gas produced by chemical fuel combustion in conventional engines is that it is powerful and can exert great power on spacecraft in a short time, but it consumes a lot of fuel, which is different from leaving the engine. It first separates the propellant, then picks up the strong field to accelerate and let them spray from the rear to obtain the driving force.
From the engine, the acceleration is also obtained through the reverse thrust, but its efficiency of working fluid is fifteen times higher than that of the conventional engine, which means that the spacecraft can save a lot of fuel. With the same fuel, the spacecraft can fly farther away from the engine, and the speed will be faster if it is long enough.
However, there is a fatal disadvantage from the engine, that is, the thrust is too small, just like the situation that the spacecraft is equipped without the engine power. It can only increase the speed of the spacecraft by 0.5 cm per second, but every little makes a mickle, and the spacecraft can accelerate more than 400 meters per second in one day. Compared with the engine, it is still an efficient propulsion method.
Zhao Huasheng nodded his head after knowing what he heard from Tang Wang.
In space flight, the spacecraft will accelerate with the help of Venus’ gravity. After more than two months’ flight, it will enter an orbit 30 million kilometers away from the surface of the sun, and then collect solar data in detail when it orbits the sun for two to four months to determine what is going on in the anti-fusion layer.
The planet closest to the sun is mercury, but even though the distance between mercury and the sun is nearly 60 million kilometers, the distance between the red heart and the red heart is 30 million kilometers, which is almost half that of mercury.
"Personally, I don’t have much confidence in changing the sun by relying on our human scientific and technological strength," Tang Wang said faintly. "I hope that the data received by the Red Heart spacecraft will be launched soon, but you can solve some clues and inspirations."
Zhao Huasheng nodded silently.
"No one said these words, but I know that all insiders, including the Fuehrer, think so. We have indeed made a breakthrough during this period, but the more we know, the more desperate we are." Tang Wang’s hand trembled slightly. "That is the anti-fusion layer that wraps the whole sun … How can we humans have the power to break them?"
"I’m sorry I was a little rude," Tang Wang said. "What are you going to do next?"
"I’m going to the equatorial city," Zhao Huasheng said. "I have some vague ideas at the moment. Believe me, I will soon find out what this is all about."
"Very good, very good" Tang Wang nodded. "Aren’t you going to Life City? There is still order and stability, and Equator City is now in some confusion. "
"No, let’s go to Equator City first," said Zhao Huasheng.
