If you have to use a metaphor to describe the difference between flying a spaceship and other spacecraft, Lin Ju believes that the most similar experience should be on a roller coaster.

Unlike rockets and airplanes, the way the Chapter 9 fights gravity is with four air-tip engines at the bottom, and the two engines at the tail mainly provide thrust for horizontal movement, but both can also be obtained at the same time through attitude conversion.

The conventional space shuttle and rocket thrust source is roughly unchanged, and the trajectory of movement also needs to follow certain rules, and most of the time Lin Ju can know how the attitude will change in the next second.

But the Jiuzhan is different, it is more similar to a quadcopter rotor, and the thrust vector adjustment range of the four air tip engines is also extremely wide, and it can flexibly switch attitudes under the control of AI.

Although the Chapter 9 is a flying machine that works in a vacuum environment, it inherits the design shape of the XN90, and has considerable aerodynamic performance even without wings, and the fuselage and propulsion modules on both sides just form the central lift body layout, and the overall lift is quite considerable at a certain angle of attack and speed.

The XN90 has been designed with sudden failure (non-human) in mind, and its aerodynamic performance can be seen as long as the initial altitude or speed is sufficient to support even unpowered forced landing.

During the take-off of the Jiuzhang to the Renshou supply point, it will maintain a flight altitude of more than 3,000 meters, and fly at a supersonic speed of more than 10 degrees of attack, during which the top speed will exceed Mach 2.

Sitting in the cockpit of the spaceship, Lin Ju could only see the sky rapidly retreating behind the porthole, and at the same time, he could feel the alarmingly loud noise in the cabin.

One of the unavoidable problems of polyhedral shape supersonic is the strong body vibration, because the cross-sectional area is larger, and the movement is much more terrifying than that of aircraft of the same class, obviously the six engines together are only 180 tons of thrust, but the intuitive feeling on the ground is comparable to that of a thousand-ton heavy rocket.

At the Renshou supply point next to the Min River, the engineers of the base have been waiting here since the Jiuzhang took off.

They temporarily borrowed an abandoned factory building by the river and cleared a large area with concrete and steel plates.

In fact, the thrust of the engine of the Jiuzhang is only 25 to 30 tons, and the concrete ground is fully able to withstand it, but the aging factor needs to be considered here to prevent the ground from being washed into pieces and flying up and hitting the spacecraft.

Almost two minutes later, the supply point saw a black irregular flying object appearing in the sky, and at an altitude of 3,000 meters, the size of the Jiuzhang was not small when seen from the ground.

Hu Dong, who was standing in the open space, was holding soundproof earmuffs in his hand and ready to put them on at any time, silently calculating the time when the supersonic shock wave would arrive on the ground.

But the first thing that came into the ears than the sonic boom were the loud and small voices in the distance, those were fishermen or locals walking near the Minjiang River, and they also spotted UFOs suddenly appearing in the sky, and they all held up their mobile phones to try to take pictures.

Hu Dong finally counted five silently, then immediately put on the earmuffs, and in a few seconds, he felt that the ground began to vibrate strongly, and the shock wave had already reached the ground.

The citizens who did not wear earmuffs only felt a steady stream of thunderstorms in their ears, and the originally calm river surface was also broken, and the scolding of the fishermen immediately sounded, but they were all covered by the detonation of the air.

On the contrary, they are already a little accustomed to sonic booms, after all, the frequent flight of Tengyun often produces such movements, and they can hear them every few days.

The most interesting thing is, of course, the UFO in the sky that doesn't look like an airplane, just when people are watching the noise video, they find that the UFO has begun to gradually reduce its altitude, and it seems that it is actually going to make a forced landing?

But the Nine Chapters moved faster than they could think, after all, its fuel was only enough for 6 minutes at most, and 150 kilometers was the maximum distance of a single jump flight in the atmosphere, and before people could fully understand it, it spun down in an oblique attitude in the air, barely hovering and constantly lowering the altitude, and the hot gas diffused by the tail flame dispersed in all directions, forming a gale.

The spaceship, which seemed to have crossed out of a science fiction movie, landed in the middle of the abandoned factory, wrapped in a cloud of dust, as if it had just experienced a fierce battle.

The fire truck, prepared in advance, hurriedly dispatched to spray water mist above the spacecraft to cool down, and when the water vapor and dust fog that enveloped the spacecraft dissipated, the hatch on the side of the cockpit spread downward, and a figure in a spacesuit climbed down, pulled open the mask and breathed in the fresh air.

Of course, this is Lin Ju himself, although he is also a skilled pilot, but the overload direction of the Jiuzhang is not simply backward but irregular, and it is still easy to make people feel dizzy when they dangle around.

The five-minute flight is comparable to a roller coaster with a rotating mechanism, accelerating and decelerating too violently.

The engineers gathered around to inspect the ship and refuel, but Lin Ju suddenly heard his phone vibrating.

"Hello?"

"Where are you now, are you on the ship?"

"Huh? Elder She, I'm shopping in the city. ”

"Fart! You've been photographed on Douyin! ”

Lin Ju saw that many citizens and vehicles had gathered outside the abandoned factory, and kept raising their mobile phones to take pictures here, and at this distance they could already see the gray "XAP" sign on the side of the spacecraft.

Many people even recognized Lin Ju's figure, he turned around and waved his hand to say hello, and then stood a little farther away from the spaceship.

"Don't worry, Old She, next time I invite you to sit too, the kind that goes directly to space, and even goes to the moon.

Needless to say, the phone is out of liquid hydrogen. ”

After hanging up the phone, Lin Ju also turned on the front camera and took a selfie of himself and Jiuzhanghao, one on Weibo and one on Twitter.

……

507.

For the joint mining exploration operation at the end of the year, five astronauts and payload specialists were selected to arrive here for adaptation training.

Among them were Rowe Rowe nuclear expert Jamie Stevenson and aerospace expert Anthony Hopkins, who had been involved in the negotiations for a while, and then moved here after a period of theoretical training at ESA.

In fact, they are only required to master the most basic space knowledge, and the main thing is to get to know the crew of their mission and get acquainted with each other to facilitate communication.

Such a short time is not enough for them to master Chinese, but Jingwei Information Communication provides a synchronous translator that does not exist on the market, and can also collect personal timbre, which is very good to use.

Now Stevenson is communicating with Academician Zhou, who also plans to go to the moon, about the structure of the moon's geological layer, which is an important basis for making plans in the early stage.

The two were exchanging ideas in full swing, and then they leaned over to Hopkins cheering and walking over with a cup of coffee.

"Jamie, we're going to get on a real spaceship!"

"Hiss~"

Stevenson and Academician Zhou both watched the short videos shot by the citizens of Renshou with wide eyes, especially the scene where the Nine Chapters fell from the sky and then Lin Ju jumped off the spaceship.

Anyone who has watched a science fiction movie can almost make up a picture of a future human spaceship arriving on a new planet, and then piloting an advanced landing spacecraft to the ground and begin to investigate.

This kind of thing actually happened in reality, and after more than an hour, the Jiuzhang took off again and flew to the dock in Yizhou, which was more shocking than landing, and it was hard to believe that what happened in front of me was the truth.

Stevenson and others can naturally recognize that this is the landing ship that United Mining will use, and the 507 Institute has built a wooden model based on its structure for drills, which everyone is familiar with.

But looking at the picture is one thing, the real flight process is a completely different feeling, and the impact of the Jiuzhang is even stronger than that of a 10,000-ton super rocket.

If it weren't for the fact that the experts knew very well that the technology used by the Nine Chapters was not too advanced black technology, they would even be tempted to suspect that this was a UFO.

"Damn, I even doubted its authenticity."

Hopkins has even publicly criticized the Chapter 9 before, because according to traditional astronautics, its ideal design method should be a cylinder like a rocket, with a simple structure and high mass utilization, and the empty weight will only be less than half of the Chapter 9.

But after seeing this non-"scientific" creation with his own eyes, he immediately rejected his previous ideas, and he had become a loyal supporter of the Spaceship Party based on his appearance and landing attitude alone.

Stevenson: "It looks like the CZ-18 will launch in half a month, and we should rent a helicopter and see what that super rocket looks like to send this spacecraft into space." ”

Hopkins: "But I have a feeling that the wake of a rocket could tip a helicopter over or even cause a tsunami." ”

"You're worrying too much about Anthony."

Although Stevenson does not understand astronautics, he is well aware of the power of underwater nuclear bomb explosions, at least the impact of rockets will not be stronger than nuclear bombs.

A lot of nuclear information is shared with Aramco, and the experience is not small.

Hopkins: "Okay then...... But we should go to Qiongzhou tomorrow, where a new spacecraft is about to be launched, and I want to go and see it.

It seems to be a passenger spacecraft used between the Tiangong space station and the Wutu space station, and it is called ...... Forehead ......"

"Dawn One."

Academician Zhou added the name for him, "Dawn" is the name of the Dawning spacecraft with the A100 nuclear engine, its name is derived from the Dawning, and the overall look is longer than the Dawning spacecraft, but the mass is much larger and close to 30 tons.

The Dawn spacecraft will be launched from Yifa Xinyuan-2 in Qiongzhou on November 19, and will conduct the first manned round-trip test after receiving the Tiangong space station, sending 1.5 tons of supplies and three astronauts to the space station in lunar orbit.

Hopkins: "Yes, Dawn One, I thought I could get on the Storm." ”

Stevenson: "I'd rather go to Advance, which is much cooler than the Space Shuttle." ”

It's been a long time since I've asked for a monthly pass~(●''●)
