The asteroid belt, the summer region.

Satellite city of New Constantinople.

A new satellite city built in the ruined area after the destruction of the HRE Federation.

It is one of the aerospace research bases jointly established by the Ministry of Aerospace and the Science Committee, which contains research institutes for spacecraft, artificial satellites, satellite cities, and deep space probes.

Among them, the Photonic Engine Research Institute is located in the third annex city of New Constantinople, and the Photonic Engine Research Institute is a scientific research institution affiliated to the Engine Research Institute, specializing in the research and development of photonic engines.

The chief researcher of the institute is Yang Tiansheng of the Great School of Mathematics, and the second researcher is also Gao Zishang of the School of Great Mathematics.

Yang Tiansheng is a mathematician, physicist, and engine engineer, while Gao Zishang is a mathematician, high-energy physicist, antimatterist, and senior engineer.

Now the new era does not have a few names, and they are embarrassed to say that they are the head of the institute, and now the scientific research community has special institutions and provisions for the evaluation of the chief researcher and the like.

Don't even think about fishing in the research institute or eating a big pot of rice, as soon as you are discovered, you may have to sing "Tears Behind Bars", even if you don't go in, this society will indirectly die socially for those who cheat.

……

Zhang Yanghao, director of the Photon Engine Research Institute, hurriedly came to Yang Tiansheng's office with a bill of lading.

"Innately, here comes what you wanted."

Yang Tiansheng grabbed the bill of lading, glanced at the contents on it, and suddenly smiled:

"Okay, the east wind has finally arrived."

He hurriedly floated towards the engine lab.

The two of them came to the engine laboratory, where Gao Zishang was busy with the improvement of the three engines with the researchers and engineers.

"Zishang, good news."

Well? Gao Zishang, who raised his head, looked fixedly: "Born, what good news?"

"The batch of parts we customized came over."

"Isn't it just ......" Gao Zishang just blurted out, and immediately reacted: "That batch of parts has arrived?"

"Yes." Yang Tiansheng handed over the bill of lading.

Gao Zishang, who hurriedly picked it up, immediately said hurriedly: "Lao Zhang, don't grind, pull things over quickly, my big knife is already hungry and thirsty!" ”

For these mantras of secondary and secondary diseases, Zhang Yanghao selectively filtered: "The things are already in Port No. 3, and the personnel of the research institute have already gone over to pull it, and it will arrive in about half an hour." ”

"Good!" Gao Zishang turned his head to Yang Tiansheng and said, "Let's have a big fight!" ”

I really can't stand this guy's secondary two disease, Yang Tiansheng stroked his forehead with his hand.

The Photonic Engine Research Institute, which has more than 300 people, took action, and as the degenerate material parts were in place, they each performed their duties to assemble these parts on the three engines.

Like the nuclear fusion engine, the photonic engine was established in the first year of the new era, and at least compared with the nuclear fusion engine, the photonic engine has three fatal flaws that have not been solved.

The defects of the photonic engine are: low fuel photon generation or photon conversion rate, extremely high gamma ray penetration, and low reflectivity of the engine's photon action plate.

These three defects are the fatal problems that plague the photonic engine, and Yang Tiansheng, Gao Zishang and others developed the first generation of photonic engines by using nuclear fusion reactions to produce high-energy photon streams and reflectors made of gamma-ray passivation materials.

The engine was developed, but the engine itself was structurally overweight, with a fuel load ratio of 34 at a speed of 500 km/s, and a lower fuel utilization rate than a fusion direct-injection engine.

Obviously, such an engine will not be accepted by the Spacecraft Research Institute.

Until the advent of degenerate materials and the mass production of antimatter, the three defects of the photonic engine were solved.

Degenerate materials can generally block photons, and even gamma rays cannot penetrate degenerate materials.

As an engine fuel, 96% of the products are various photons, and 4% are pure thermal energy, which means that the photon conversion rate of antimatter fuel is 96%, which is hundreds of times higher than that of nuclear fusion fuel.

According to the photonic engine research data on the Nibelon spacecraft, accelerating the spacecraft to 10% of the speed of light results in a fuel-to-load ratio of about 0.4, or about 1 if braking and other needs are added.

With a fuel-to-load ratio of 1, a 1,000-ton spacecraft can fly at 10% of the speed of light with 1,000 tons of fuel on its board.

……

Custom degenerate parts are assembled on the engine, although they are less performant than the Nibelon photonic engine (degenerate materials cannot be molded in one piece, resulting in reduced performance).

The engine of the same class, the engine of the new human, brings a fuel load ratio of about 1.2, and the fastest speed is about 8.5% of the speed of light.

Looking at the engine that had been formed about 80%, Yang Tiansheng turned his head and ordered: "Lao Zhang, you go to prepare the spacecraft for the experiment, and the day after tomorrow we will install the engine and take a walk." ”

"No problem."

May 1, 4th year of the new era.

Port 4 of the satellite city of New Constantinople.

Not only people from the Photonic Engine Research Institute, but also people from the Spacecraft Research Institute were also there.

The spacecraft for the experimental photonic engine was provided by the Spaceship Research Institute.

The spacecraft is transformed from the Tianzhou-class, and the main body of the spacecraft still adheres to the format of the Huo Quzhi-class, but the three photon engines added this time are different from the previous tail-mounted engines.

Three photon engines are installed in the middle of the spacecraft, which is somewhat similar to the core first-stage booster child body in the space rocket, the engine child body is hung in the middle of the spacecraft, which can rotate 360 degrees, plus the engine nozzle can be vector controlled, which can quickly realize braking and orbit change.

The use of this kind of mid-mounted rotary external engine can not only quickly brake and change orbit, but also facilitate the upgrading of old spacecraft.

Inside the control tower of the port, Gao Zishang asked with some anxiety: "Is this spaceship reliable?"

After all, anyone who sees a spaceship full of rivets has to beat a drum in their hearts.

The researchers of the spaceship research institute on the side were also embarrassed, and they had no choice but to use it before the integrated molding technology of degenerate materials.

Yang Tiansheng hurriedly alleviated the embarrassing atmosphere at the scene: "There shouldn't be much of a problem, after all, it is the shell of degenerate materials." ”

Three spacecraft testers boarded the spacecraft, and because it was a modified version of the Tianzhou-class, the testers easily entered the anti-load support chamber.

[Deep Space is ready.] ］

[Tower received.] ］

A tugboat pulls the Deep Space and flies into the distance, the vents of the photonic engine are no more than those of a laser.

Although the engine's action plate can effectively passivate a part of the gamma rays, once the engine is running at full load, the gamma ray flow emitted by the engine can severely damage unprotected targets within 5,000 kilometers.

If the passivation grid is removed, the maximum range of the gamma ray stream emitted by the engine is 700,000 km, and within 100,000 km, the old gamma ray protection technology will not help at all.

This is a proper high-power laser, and the photonic engine can be used as a weapon at critical moments.

Therefore, you must not fly casually near the satellite city, otherwise if you are not careful, you may have a big accident if you wipe your own satellite city or other spacecraft.

The tugboat pulled Deep Space 100,000 kilometers away from the new Constantinople satellite city before the tests officially began.
