June 9th was the day for the test flight of the Colorful Stone Group's "Overlord Gun" aerospace aircraft. At this time, the "Overlord Gun" aerospace aircraft had already stopped at the starting point of the flight runway with the busy ground crew.

Chen Zhichao and Ren Hongying walked to the side of the aerospace plane amidst the envy of everyone. Although many of the ground staff present at this time were members of the Dahua Empire's aerospace force, and many of them had also received professional training.

The astronauts were training, but no one was emotional because they clearly knew the importance of this test flight.

And although they say that many of them have received training as astronauts, it was only a few years ago, before they came to the Aerospace Forces, and now they are no longer able to do so.

Of course, since this test flight was a manned test flight, there were more people in the observation group than in the last unmanned test flight. There were hundreds of people from Dahua Imperial alone. In addition, there were also Dahua Imperial

Many high-level personnel also came to the scene to watch the test flight of their Colorful Stone Group.

Because both the military and high-level leaders of the Dahua Empire know that once their test flight of the "Overlord Gun" is successful, it will definitely be the biggest opportunity for the Dahua Empire, and the country may even adjust the state

strategic direction.

At the same time, this time is not the same as last time. Except for the official media of the Dahua Empire, there is no media. On the contrary, this time there was a test flight. Zhang Yi and his Colorful Stone Group asked many domestic news media

Come to participate, there are many unofficial media reporters and self-media people.

With the help of the ground crew, Chen Zhichao and Ren Hongying put on the mechanical outer armor spacesuits that had been developed by Colorful Stone Group.

After putting on the space suit, Chen Zhichao moved around for a while and felt very good. Although the mechanical exoskeleton armored space suit looks very clumsy from the outside, in fact, the mechanical exoskeleton armored space suit is both flexible and flexible.

In terms of resisting strikes or protecting the safety of internal personnel, exoskeleton spacesuits are incomparable to traditional spacesuits.

"Chen Zhichao! Ren Hongying! Are you two ready? The aerospace plane is about to conduct a test flight. If it is ready, please board the plane immediately." At this time, as the commander-in-chief of the manned test flight of the aerospace plane,

, Xiang Juncai’s voice came from the headset of the exoskeleton spacesuit.

"Report to the commander-in-chief! We are ready to board the plane at any time." Chen Zhichao, who has been appointed as the captain of the "Overlord Gun" space shuttle, replied.

"Okay! Then board the plane right away."

After finishing speaking, Chen Zhichao and Ren Hongying boarded the "Overlord Gun" aerospace plane, and began to further familiarize themselves with the internal structure of the aerospace plane and various function buttons with the cooperation of the command center.

After all, although an aerospace plane is also called an airplane, it is still very different from the operation of an atmospheric hiccup aircraft. At the same time, the operation method of a spacecraft is also very different from what they learned at the astronaut training base. Although it has been

After these two days of familiarization, they already have a general understanding of the operation methods of aerospace aircraft, but they are not very familiar with it yet.

"Chen Zhichao! Ren Hongying! Order you to start the self-inspection procedure of the aerospace aircraft and begin the final self-inspection of the aerospace aircraft!" Xiang Juncai's voice came from the headset again.

"yes!"

"The fuel system is OK!"

"The power system is normal!"

"The engine is fine!"

""

"Everything on the aerospace plane is operating normally and can take off at any time."

"Permission to take off!"

Under everyone's attention, the aerospace plane began to glide slowly. Blue flames were sprayed out from the engine behind the aerospace plane. It can be seen from the color of the jet flame that the temperature of the flame is at least 2000 degrees.

above.

As the engine started to work, the aerospace plane began to accelerate. Since the aerospace plane was carrying two space station sections and was close to the maximum load capacity of the aerospace plane, the taxiing distance of the aerospace plane was very long.

After taxiing for 7 kilometers, the nose of the aerospace plane was raised, and the entire aerospace plane slowly left the ground.

After leaving the ground, the aerospace plane did not accelerate. Instead, it circled over the base and began to perform some more complex actions to test the performance of the aerospace plane. However, this is a large aircraft after all. Even if

No matter how complicated the action is, there is still a certain gap between it and a real fighter jet.

After this period of hard work, the various equipment in the command center of the base have become very advanced. At the same time, in the base of Colorful Stone Group, their group has also built its own space observation station, so at this time, in the base

In the center of the command center, a huge virtual display is displaying various actions of the aerospace plane and various data of the aircraft.

"The telemetry signal is normal, the radar is normal!"

"The flight attitude is normal,"

"Report to the command center, this is the "Overlord Gun", everything on the aircraft is normal, request for acceleration, request for acceleration."

"You can accelerate, but the maximum speed must not exceed Mach 45!

repeat!"

After receiving permission from the command center, Chen Zhichao began to increase the throttle, and the aerospace plane began to increase speed. After 20 seconds, the aerospace plane directly broke through the sound barrier. Because the aerospace plane is very large, when the speed breaks through the sound barrier, it emits a sound in the sky.

A terrifying scream.

"This is the command center. This is the command center. Chen Zhichao asks you to report the current situation!"

"All conditions are good, fuel remaining 90%, altitude 20,000 meters, speed Mach 4."

"Continue to accelerate and maintain the climbing speed. At the same time, please pay attention to your own condition. If you feel unwell, please return immediately!" Xiang Juncai said to the communication device.

In fact, this is the advantage of the aerospace plane. If it is a rocket, if the astronauts feel unwell during the launch, there is nothing that can be done. However, the aerospace plane is different. Once the astronauts become unwell during the process of entering space, the astronauts may become unwell.

If you feel unwell or otherwise encounter an accident, you can abandon the mission at any time, and the aerospace plane can return at any time. At most, it will only waste some fuel.

After all, compared to the lives of astronauts, the little bit of fuel consumed by the aerospace plane is nothing. The most important thing is that the aerospace plane uses water as fuel. Ten tons of water is not worth it at all.

A few dollars, wasted.

"receive!"

After finishing speaking, Chen Zhichao and the others operated the aerospace plane and continued to fly to higher altitudes. At the same time, the speed of the plane also gradually increased.

Although the speed of the aerospace plane has reached Mach 5 at this time, the overload force experienced by Chen Zhichao and others has also reached more than 4g. Since they wear mechanical exoskeleton armor, it protects their bodies very well, so although they have already
