Class B base.

On the night of the three-day holiday, all the B+ and above personnel were concentrated in the basement, and there was no other ...... There is also a "waiter".

A "woman" dressed as a secretary slowly brews coffee and tea to everyone's liking, and stands quietly in the corner after putting it away.

Lin Ju glanced at the improved No. 2 robot that had been covered with silicone skin, coughed to make several people present concentrate, and then stretched out his hands in an impatient gaze, and a book that was not too thick appeared in his hand out of thin air.

The simple black cover reads "Introduction to Radiation Propulsion Technology" and the corresponding author's name, not even the publishing house, and there is a "top secret" stamp in the lower right corner.

Ye Changsi, who couldn't wait for a long time, stood up and came over directly, opened the catalog excitedly, and read this book from another world more than twenty years later with several other pairs of eyes.

"Part I: Several Approaches to Fusion Technology

Part II: Mainstream Propulsion Technology Concept

Part III: Prospects for Radiation Propulsion Technology

Part 4: Related Papers (404 internal publications)"

With a total of only 130 pages and only four parts, it is obviously not a heavy technical catalog, but a supplementary book like "Introduction to Interstellar Navigation", most of which is the author Zhao Zongyao's conception of his radiation propulsion theory.

But what attracted engineers the most was the first 17-page introduction to fusion technology, which has three subsections corresponding to the three ways of nuclear fusion that can be achieved in that world.

The most difficult thing in the world today is not knowing which fusion technology is feasible, and these 17 pages can point the way to the future.

Lin Ju, who knew what his level was, naturally gave up his position to Ye Changsi, who had the most knowledge in this area, and watched the latter turn the pages excitedly.

A group of engineers pressed close together and saw the first paragraph of the first part.

"Research into fusion technology has never stopped since the world of atomic energy opened its doors, and this power from the sun is probably the most powerful means that mankind can master and use for a long time.

There are many ways to fuse light nuclear molecules such as hydrogen, deuterium, tritium, and helium, but they can be roughly divided into two categories: inertial confinement fusion and magnetic confinement fusion, which are not mutually exclusive, and more than 30 fusion devices have been built around the world in the past 100 years, basically within the scope of these two methods.

Whether it is laser, plasma or magnetic capture, the principle is to create a high-temperature and high-pressure environment, and at the same time, the more efficient the fusion method, the higher the temperature and pressure, especially the clean helium triple fusion.

The radiation propulsion technology discussed in this book is based on the prospect of laser confinement inertial plasma fusion technology, although this technology is not yet mature, but it has been confirmed by scientists from all over the world to achieve stable helium-3 high-efficiency fusion, with many advantages such as small size, less waste heat, light weight, and high power generation efficiency.

The important breakthrough of laser confinement inertial plasma nuclear fusion is based on the "Yu Qian's formula" proposed by Academician Yu Qian, a famous scientist in China, to further explain the unified equation of Yang Mills's electromagnetic force and weak force, and uses the weak interaction between atoms to realize the normative confinement of plasma......"

Lin Ju read the first high-end word "weak interaction force", and the following is Zhao Zongyao's explanation of "Yu Qian's formula" and the introduction of laser-confined inertial plasma fusion.

Obviously, there is a cow named Yu Qian in that world line who has made important contributions to controlled nuclear fusion, so much so that a theory named after him has appeared, and it can be seen from the exclamation of Ye Changsi Seryov and others that this must be a theory that has not yet existed or been confirmed in the world.

But the part that Lin Ju can understand ends here, and the author of "Introduction to Radiation Propulsion Technology" obviously knows that this book is for people in the internal research institute, and there are not many text explanations, most of which are occupied by formulas and diagrams, which only professionals can understand.

He struggled to make sense of the shortest formula, and then gave up obediently.

In fact, Ye Changsi, Cheng Nankai, Zhao Xiaowen and others know about nuclear technology, and the rest of the engineers are almost not involved, but they can understand some of the content.

"Paper, I need to do the math!"

Ye Changsi said without raising his head, Lin Ju patted the hip skirt of the No. 2 robot that was supported by silicone, and the latter immediately went to get the pen and paper, and soon only a small but rapid discussion and the rustle of the tip of the pen on the paper remained.

The first part of the most concise is all the essence of the current unconfirmed theory, these discoveries are definitely Nobel Prize-level, Ye Changsi can solve many doubts in the past at a glance, only to feel that the front of the fusion road is being illuminated by a street lamp, more and more open.

Although Lin Ju couldn't understand it at all, he was still infected by this excitement and waited silently in the basement.

……

Texas.

First of all, Ami does not have a holiday on May Day.

So Musk can make more than 7,000 employees of SpecaX work overtime for SN11 flight tests, what, isn't it only SN8 in April?

The SN9 and SN10 prototype test spacecraft exploded before they could reach the test altitude of 15,000 meters, and even the SN8 was not as good, and the SN11 was only pulled out of the factory building the day before yesterday, and it was ready to be launched on May 2.

The reason why it was built so quickly is that the interior of the starship spacecraft up to now is extremely rudimentary, and there is nothing inside, just a simple stainless steel shell (no heat insulation tiles), just a sample arrow for testing in the atmosphere.

Of course, more importantly, SpecaX is desperately producing Raptor V1 engines, and now it has exceeded 80 units in stock, and it is only a waste of production capacity of three Raptor V1s (only three sea-level engines are installed, not vacuum engines), which is completely affordable.

In fact, the spaceship in Starship Factory has been numbered to SN19 and is preparing to be blown up.

The test results of SN11 were not unexpected, Musk glanced at the attitude of the starship, it was too oblique, and the position of the center of gravity should be at the edge of the thrust centerline, which could not be saved.

Half a minute later, SN11 was ready to struggle at full power before hitting the ground, but it was still smashed into a mass of steel wreckage, and experienced firefighters swarmed up and quickly extinguished the flames with foam.

The flight data was sent back before the crash, but this will not have much impact on subsequent tests, and both SN13 and SN14 will continue to be launched until May 25, and as for SN12, it has now been transported to the launch pad.

The SN12 and SN11 are built in the same batch, but with three vacuum-powered versions of the Raptor V1 installed and half-sided insulation tiles, which will be combined with the B6 booster for a non-recovery test launch, which will be successfully put into orbit before recovery.

Although seven or eight Starships have been blown up, Musk believes that the success rate of not recovering normal orbit should still be good.

There are a lot of things to do this week, and there are only two more guarantees for the time being......
