Ultra-Dimensional Technology Era

[120 km/s...11 seconds]

[567 kilometers...]

The final speed stayed around 1170 kilometers per second.

After entering the constant speed flight, the interior of the spacecraft will not be affected by the acceleration, and the engine will gradually reduce the injection of antimatter, and enter the state of constant speed inertial flight.

After flying at this speed for two hours, the Deep Space has traveled more than 800 million kilometers.

[Enter turning course. ] Ren Yingwu ordered.

[receive. ]

The spacecraft's engine enters vector control and begins to adjust the flight direction.

When the spaceship reaches the position of the turning angle of 1000 kilometers, the spaceship is already flying parallel to the sun's ecliptic plane.

This is an empty waterway, without dense celestial bodies and spaceships passing by, the Deep Space can roam the void unscrupulously.

[Range 2673/0267/2411, target Cooper belt - NM36 satellite city, advance at full speed. ]

[receive. ]

The power of the three photon engines of Deep Space is gradually increased, and the outrageous flow of photons and neutrinos pushes Deep Space to sprint forward.

The speed on the virtual display is crazily beating 2760...5027...8391...

[alarm!Encountered a free particle cloud...]

If someone could see the Deep Space, they would observe that the front half of the Deep Space was experiencing a terrible impact, countless free particles in the void, and the surface of the Deep Space had sparks.

Ren Yingwu looked calm, this was expected, as long as the speed is fast enough, there will be a reaction when it hits an atom.

When the speed exceeds 1.8 kilometers per second.

[Alarm, photon pressure 0.0214...]

The so-called photon pressure is a kind of resistance that the spacecraft will inevitably encounter when it enters the sublight speed flight state. It can be understood as something similar to air resistance.

The closer the speed is to the speed of light, the greater the light pressure on the front of the spacecraft. Once the spacecraft enters 90% of the speed of light, it will be like being in the collision chamber all the time.

Ren Yingwu stepped on the accelerator to the bottom, and after 3.7 hours of continuous acceleration, the Deep Space finally reached the limit.

At this time, the flight speed of Shenkong was 2.34 kilometers per second, equivalent to 7.8% of the speed of light.

This speed is about 8% slower than the estimated 0.2% of the speed of light.

After reaching the limit speed of 2.34 kilometers per second, the spacecraft engine enters a low-power inertial flight mode.

Deep Space only needs to use part of the power to offset the free particles and light pressure.

Of course, this flight speed can actually be increased, but if it continues to accelerate, it will cause the spacecraft to lose braking and return fuel, and become a lone ship drifting in the universe forever.

24小时之后，深空号已经前进了20亿公里，距离NM36卫星城不足157亿公里，8天左右便可以达到NM36卫星。

Compared with the previous flight range of five or six hundred days, it took nine days to cover 9 billion kilometers, which is almost boundless.

This speed is almost enough for use in the solar system.

……

New Constantinople satellite city.

The data sent back by the neutrino communication made Gao Zishang excited: "It really is an antimatter fuel, which is a perfect match for a photon engine."

"It seems that there are no major problems with the prototype machine. After some improvement, the first-generation photon engine can be launched." Yang Tiansheng said while browsing the data.

The people of the Spaceship Research Institute also became happy, and the low-sublight speed spacecraft can finally enter the development stage.

［注：低亚光速是指飞行速度低于光速30%，另外还有中亚光速（光速30%～59%）、高亚光速（光速60%～89%）、极亚光速（90%～99%）］

Gao Zishang flipped through the data, and suddenly turned his head to the people of the Spaceship Research Institute and said, "Shen Kong has some stress damage, take a look."

Why? They hurriedly browsed the data fed back from the Deep Space. After reading the data, Mi Wanli, the spacecraft design engineer, replied helplessly:

"The acceleration of the photon engine is too fast, and a part of the Deep Space structure cannot withstand this acceleration. We will improve it."

"Degenerate materials can be used as the skeleton of the spacecraft." Gao Zishang suggested.

Regarding this suggestion, Mi Wanli shook his head: "Our degenerate material processing technology is not good. If a large number of degenerate material parts are used, the spacecraft will be overweight."

"That's it!" Gao Zishang frowned.

This is a very helpless reality. Nibelon can use a large number of degenerate materials as spacecraft parts because the degenerate processing technology of the other side is better than that of new humans.

For example, the N16-N-2 shell of the Nibelung spacecraft has only one layer, but the new humans need three layers, resulting in a weight 3 times higher than that of the opponent under the same area.

The degenerate material itself is overweight. If it is applied in large quantities, the dead weight of the Tianzhou-class spacecraft made of ordinary materials is about 670 tons, while the degenerate materials may reach more than 1 tons.

Faced with this situation, the Spacecraft Research Institute can only reduce unnecessary parts and use degenerate materials as much as possible to prevent the spacecraft from being overweight.

The design of a spacecraft must balance the power of the engine and the dead weight of the spacecraft.

3 Chapter [-] Return and Improvement

New Era 4, April 5th.

11:34 a.m. Blue Star time.

The three photon engines that have rotated 180 degrees eject photons and neutrinos forward and backward, and brake through the reaction force.

In space navigation, it is not only necessary to be able to fly at high speed, but also to be able to perform high-speed braking. If the spacecraft can only fly but not brake, it will never return.

Cannonballs or missiles can choose the way of no return, but the spaceship definitely cannot use this way.

When the last ray of photon was ejected, the spaceship docked firmly at the spaceport next to the satellite city of NM36.

This is an unmanned satellite city, a factory-type satellite city dedicated to the production of Luban-class transport ships.

Levi exited the anti-G survival cabin, took out a nano-robot reserve bag from the cabin, and his own spacesuit can be used in outer space.

After the airlock was opened, he activated the nano-robot to take charge, and drifted to the interior of the NM36 satellite city.

Since it is an unmanned satellite city, there is no standard cabin for human use, not even an airtight passage.

On the empty satellite city, Li Wei is the only human being active.

While Ren Yingwu and Park Quandao were inspecting the spaceship, the continuous acceleration and deceleration caused considerable damage to the hull structure of the Deep Space. For safety reasons, they now plan to use the spaceship on the satellite city to build a dock for maintenance.
