.Japan Kashou radar station monitored mainland China yesterday. An unknown aircraft of different types from China took off from the southwest inland area, hovered at an altitude of more than half an hour at an altitude of 8,000 meters, accelerated to fifteen g, and reached dozens of kilometers, directly rushing out of the atmosphere. Since then, the aircraft used rocket boosting to fly to a low orbit more than 600 kilometers from the ground. During this period, the rocket shut down many times and used gliding flights. This is the first time that humans have a vehicle that flew directly from the ground to space and reach a low orbit..."

"The International Space Station confirmed that yesterday, a new cross-space vehicle from China entered low orbit and flew around the earth three times along orbit. After that, the aircraft's rocket engine was started and returned to the atmosphere. Russian astronaut Joelkin believed that it was time for China to join the space club and that politics should not be allowed to become a stumbling block that hindered countries from launching space exploration."

"The Houston Space Center confirmed that China's new model aircraft did take off from the ground and enter space directly. Whether it is provoking the United States or something, it is not yet clear."

"The US President spoke on the phone with the Chinese leader last night, and the two sides exchanged views on the international situation. The US President congratulated the Chinese leaders on their success in the development of cross-space aircraft, and said that China and the United States are world powers and should join hands to jointly maintain world peace. The Chinese leader agrees with his point of view, saying that China has always been based on peacefully developing space resources and will never engage in arms races. Both China and the United States have common interests and should communicate more on international affairs for world peace and prosperity."

"The European Space Agency said today that yesterday China conducted the first cross-atmosphere flight in human history and achieved success. After hearing this news, many scientists came from China's scientific and technological progress, which was both unexpected and reasonable. China has a population of 1.3 billion. It graduated millions of college students every year and has the richest talent reserve in the world. From the technological development in recent years, it can be seen that China will become a world power. The 21st century is destined to be the Chinese century. Europe is willing to work with China to jointly carry out broader cooperation for the progress of human civilization. An official from the European Space Agency who did not want to be named said that Europe is interested in renting China's cross-atmosphere spacecraft to build a new scientific research space station."

"Sleeping dragons have been out of control since they woke up in 1979. Their transatlantic aircraft will become a nightmare for all peacemakers. We should..."

"Products made in China have seized many jobs for workers. Since yesterday, people have to worry not only about their own jobs, but also be more wary of bombs falling over their heads..."

"We must think clearly about this issue whether China is a threat or an opportunity. The Japanese government said that the situation of government and hot economy should be completely corrected. China and Japan are neighbors with a strip of water. The two countries have a history of friendship for thousands of years. It is a stupid act to encircle China. We should change our course..."

"The Korean Daily reported that the Chinese have come to the Korean Peninsula more than two thousand years ago. The earliest ancient kingdom of Korea was established by people from the Central Plains..."

...

Han Kun was pressed tightly into the seat with a huge overload. His hands were almost unable to move. He felt that the skin on his face seemed to be under a huge overload. He pulled and deformed, as if he was about to fall off his face.

This is their 41st test flight. The previous few times were tested for ground take-off and landing and low-altitude flight capabilities, and did not fly to high altitudes.

The aerospace plane is indeed not a good atmospheric aircraft, and it is quite difficult to operate in the atmosphere. Although it has the Hongjun intelligent system to assist in the control, it still makes him feel nervous every time he takes off and lands.

In order to ensure the safety of the pilots, the engines of the aerospace plane only took 500 hours each time and were replaced immediately. Usually, every time they returned from a test flight, they would also undergo strict engine maintenance. Han Kun and the other pilots were the company's treasures, and no one dared to let them have any surprises.

Today, a series of tests in the previous area have been completed, and all the data indicators in the area are consistent with the predictions.

This also greatly encouraged all researchers' confidence. After research, it was decided to conduct the last test to complete the test of flying directly from the ground to outer space.

To ensure the test success, all pilots took a two-week break.

The researchers also conducted the highest standards of tests on the aerospace plane, every component, every instrument, and even every screw. They wanted to ensure that when Han Kun and others conducted this dangerous flight test, the prototype of the aerospace plane was in the best condition.

The base also specially allocated a new engine to allow them to have sufficient power support.

The aerodynamic performance of the aerospace plane is too poor. Takeoff and landing are all tortures that test the pilot's nerves. They are trying to believe in the Hongjun assisted driving system, which seems that the intelligent driving system is more adaptable to sensitive airflow than them.

However, they never dared to give their lives completely to the cold light brain.

Although this thing reacts quickly, it relies on data transmitted by various sensors when it is flying an aircraft. If any sensor fails, it will still drive in the normal way. If you believe it completely, you can only sit and wait for death.

The outside of the aerospace plane is coated with stealth paint, which can effectively reduce the reflection area of ​​the radar wave. From the radar, people will feel that this is a small aircraft. Of course, this is when flying at low altitude and low speed. As long as the speed is increased, fools can tell that it is an ultra-high-sonic aircraft.

And the size of the reflected waves from the radar is reflected, many people will regard it as an ultra-high-sonic fighter.

Han Kun and his crew used the turbine engine first and circled at low altitude for a while. The airflow in the mountains was very unstable, and the crew members were all wary, fearing that the plane would wipe the mountain.

After that, under the command of the ground, Han Kun and his team began to fly the space plane to hover upward, and their speed gradually increased to Mach 3.

As for turbine engines, such speed is close to the limit of this model. Because it is a combined engine, no one dares to raise it to a theoretical limit like Mach 5.

They prefer to use rocket boosters.

The scientists at the base have improved the rocket engine, which can start and shut down multiple times, thereby bringing the efficiency of the rocket engine to the maximum efficiency. Instead of wasting valuable fuel during the acceleration process, they can use taxiing to increase the range.

The overload is no longer small at this time, and ordinary people may not even be able to bear this level of pressure. But for Han Kun and the others, this is just a piece of cake, with anti-duty compensation service protection, and this overload just makes them feel a little uncomfortable.

But the Rockets boosted

They felt a heavy pressure on their chairs

The overload of Mach 5 has reached their human body's limit. Many movements are extremely difficult to do. It is entirely due to the help of the anti-duty server that they can resist the increasing overload and continue to control the sky plane to climb upwards.

The rocket booster was turned on for only a short while and then stopped.

Because the transcendent ramjet engine has been ignited and started. The huge roar, although it was in the closed cockpit, was clearly transmitted to the cockpit.

The aerospace plane has already flown to an altitude of 12,000 meters.

With the assistance of the co-pilot, Han Kun slowly increased the speed of the aerospace plane.

Mach 5, Mach 6, Mach 7. He stopped to continue to accelerate.

He felt that at a high altitude, the heavy aerospace plane became much lighter and could be done more easily. Although the anti-duty service made him slow, the lightness of the operation also made him control the aerospace plane more convenient.

It is indeed a transatlantic aircraft. Only at this thin altitude can its value be reflected!

"The special service team of the Kongyi Special Service Team is paying attention. Let's conduct the last subject test: fly across the atmosphere!" The sound in the headphones became a bit strange because of the ultra-high speed flight and the signal reception was unstable.

"The special service team of the Kongyi team understood that this would be transferred to the last test subject." Han Kun repeated the instructions to the ground command, then turned on the internal telephone, "Everyone checked the fixture. We are about to accelerate to Mach 15 and enter a transatlantic flight."

"receive!"

The members of the air crew all checked their fixtures.

Everyone knows what it will be like to fall off from the flight seat during a high overload flight of Mach 15. Everyone does not want to become a pile of flesh, nor does they want their flesh and blood to destroy the internal instruments of the cabin.

"After the inspection, all crew members have been fixed." The co-pilot's voice was a bit muffled. He was the second commander of the team. He was usually responsible for assisting Han Kun in managing the entire flight team. If necessary, he would take over Han Kun's position.

Just like a conscientious butler, Han Kun doesn't need to worry too much about all trivial matters.

Han Kun also checked his own fixture. He took a deep breath and turned on the driving button of the Hongjun Assistance System: "Hongjun Intelligent Assistance System, take over the driving. Command: Get out of the atmosphere! The ultimate goal: reach the 600-kilometer track!"

With a huge overload of Mach 15, he could not control the aerospace planes flexibly and fly correctly, especially at the moment of engine conversion. Someone operates it, and computers control it. At high altitudes, he is still willing to believe in Hongjun's intelligent value system. This is based on the established route, flying directly upward. In the power conversion, the light brain does not have the pain of overloading them, and can always maintain awakeness and extremely high sensitivity. As long as it is not complicated to fly, the intelligent driving system is still very useful.

On the pilot, the red light flashed and went out, and the electronic sound spread to all crew members.

"Hongjun Intelligent System, officially takes over flight control, command, breaks away from the atmosphere. The ultimate goal: reach a 600-kilometer orbit and fly around the earth. Please confirm the command!"

"Confirm the order!" Han Kun held the handrail tightly with both hands.

"The acceleration is turned on, and the aircraft will reach a maximum speed of Mach 15 within one minute. Please all crew members to protect themselves from their safety." Although Hongjun's intelligent system said a reminder of concern, the cold electronic sound had no feelings.

He suddenly felt a heavy body, and a huge pressure came from the front, pressing him on the back of the chair, unable to move.

The seats are automatically adjusted with overload and tilted to 63 degrees, almost parallel to the deck floor.

The corresponding pressure came from the abdomen and lower limbs, causing the blood to rise to the head. Even so, he felt that his brain was gradually deficient in oxygen and his thinking became erratic. The images in front of him seemed to be blurred. www.piaotian.com.com    In a trance, the violent shaking of the sky plane became less intense, and his body was as light as if he had no weight, floating in the endless universe.

The space plane has accelerated to Mach 15 now, so it will soon rush out of the troposphere...

He opened his eyes and looked at the dashboard. He found that the speed was only Mach 13, and it had not accelerated to the highest level. At this time, the altitude was only 15,000 meters above the ground, and there was no conflict with the troposphere.

There is a little freezing outside the cabin. This is because the air in the upper troposphere is very cold and is always below zero. It is filled with ice crystals and cooling water droplets. Due to the very unstable airflow, the shaking of the aerospace plane during this flight is even more intense.

Finally, in the painful torture, the space plane broke through the thick clouds and came to the stratosphere.

The air in the stratosphere is very thin, and the shaking caused by the airplane due to atmospheric resistance suddenly becomes calm. Below is a continuous cloud layer, boundless. The air above is very thin. It can be seen without any concealment. The sunlight shines from above, turning the entire cloud layer into a golden ocean.

Entering a height of 60 kilometers, starting from here. Being affected by solar rays, x-rays and high-energy particles, all the way to the atmosphere of 1,000 kilometers, it is affected by partial ionization and complete ionization. Therefore, this strata is also called the ionosphere.

The ionosphere has a great impact on the instruments and instruments of aircraft and can easily destroy some precision instruments.

Han Kun and others endured the aerospace plane flying at the second cosmic speed. They didn't care about all the changes in the scenery outside the window. Even the dazzling aurora belt that traveled through a hundred kilometers, the dazzling aurora could not arouse their interest.

The rocket engine starts, stops, starts, stops, and reciprocates several times. Each time, after the speed exceeds the second cosmic speed of eleven kilometers per second, the engine stops its operation and continues to glide forward using inertia. When the speed decreases, the engine is started and the acceleration is accelerated again.

Finally, Han Kun and his friends suffered to the end. The speed of the aerospace plane slowly dropped and slowly entered the low-Earth orbit of 600 kilometers.

Here, they only need to fly around the ground with the first cosmic speed (7 kilometers per second).

Because the flight speed just offset the suction force of the earth's center, Han Kun and others felt relaxed and gradually floated up. They were just bound to the seat and did not float away.

In fact, the gravity cup at the center of the earth is not completely offset, and this is not a completely weightless environment, but a microgravity environment.

They only need to use a small force to apply a forward motion.

However, Han Kun and others could no longer notice this tiny difference. In front of them, there was a brilliant starry sky. The light of the sun was so dazzling that it was hard to look at it directly.

This is outer space, we flew from the ground to outer space!

On the ground, the stars with faint starlight were so shining at this time. The sky was full of stars scattered in the sky, forming

The sea is like a dazzling gem, inlaid on a pitch-black curtain, and needs to be picked out with one hand.

"It's so charming!" A heartfelt admiration sounded from the inside phone in Han Kun.

Everyone was intoxicated by the stars outside the window.

Under the influence of the earth's rotation, aerospace planes circled the earth and flew in an elliptical orbit with inertia. At the closest time, they were only 600 kilometers away from the earth, while at a distance, they reached 240,000 kilometers.

Therefore, only when orbiting, you need to change the orbit through the rocket engine to pass through the orbit, reach the geostationary orbit, fly around the equator, and become a geostationary satellite.

If you continue to stay in an elliptical orbit, due to the multiple gravity of the sun, the moon and the earth, coupled with the atmospheric resistance, the perigee will slowly decrease. The apogee will decrease at a faster speed. Finally, a circular orbit will be formed, and gradually lower the height, fall into the atmosphere, and return to the embrace of the earth.

This time can be several years long, while the shortest may be only a few days.

This requires aircraft or satellites to continuously pass through rockets and adjust their flight attitude to stay in space longer.

However, for satellites with a theoretical lifespan of more than 1,000 kilometers, it can reach more than 1,000 years. For human scientific research and life needs, it is almost a permanent satellite.

Han Kun and the others only stayed in space for a few hours, took a lot of photos, and then they had already flew around the earth for three times.

While they are studying the earth. While collecting relevant data through a large number of equipment carried by aerospace planes, they themselves have become the target of research around the world.

When they were flying at low altitudes, they had not been discovered because of the small radar reflection area and were far away from foreign ultra-long-range radar stations.

However, when they jumped to a high altitude, there was no large amount of clutter interference. There were countless ground radar stations, space detection devices, astronomical stations, space stations and satellites in space, and their traces were discovered.

Countless eyes focused on their aerospace plane.

When they saw them moving up with all their might, many people were frightened. Is this a suicide shock or a cross-atmosphere flight?
