Rebirth 99 to become a car giant

Granfen is in a complicated mood now.

Whether the United States really landed on the moon is not a topic that has only emerged in the past few days. It has been hotly discussed in the United States for a long time.

Even every once in a while, the popularity of this topic will increase.

Since Venus Technology started the journey to the moon, this topic has also become a lot hotter in the United States.

It would be a lie to say that Granfen has no pressure at all.

But he did not expect Venus Technology to come out to refute the rumor, saying that NASA did not fake it, and that they really achieved the moon landing that year.

However, she did not have much time to worry about it.

Because the spacecraft carrying lunar soil from Venus Technology will soon return to Earth.

At that time, the large amount of lunar soil they carry will be deeply studied in many subsidiaries of Venus Technology.

Combined with these research results, there will definitely be a lot of news.

But what Granfen did not expect was that the first news was actually the way Venus Technology's spacecraft returned to Earth.

On May 22, 2016, the lunar spacecraft of Venusstar Technology, which had been "traveling" in space for 53 days, returned home.

This time, it not only brought the "lunar soil" that many countries had lined up to receive, but also put on a "performance show" on the way home.

The "skipping stones" landing method adopted by Venusstar Technology this time is a "unique secret" that only China has mastered so far.

This technology not only makes many Western countries envious, but also makes some countries panic.

According to the technology used by the return of aircraft in the past, most of them rely on their own rocket thrusters to "reverse propulsion" after entering the atmosphere, thereby reducing the speed generated during the fall.

When it drops to a certain speed and altitude, the engine is shut down, the aircraft opens the parachute for deceleration, and finally lands in the designated area.

This method can be said to be the technology used by all aircraft except Venusstar Technology so far, but this technology has very high requirements for carrying fuel.

But it actually has obvious disadvantages.

During descent, the intense air friction and the tail flame of the rocket will also bring the outer shell of the aircraft to a high temperature of up to 1000 or even 2000 degrees, and at the same time, the "black barrier" phenomenon of communication failure will occur, which will increase the danger of the aircraft invisibly.

However, this time, Venus Technology adopted a special "skipping stone" landing method.

Although many people have played the game of "skipping stone" when they were young, few people can hit the target as accurately as throwing darts.

But Venus Technology can adjust the flight route while maintaining high-speed landing, and finally land accurately at the landing point in the grassland province.

This is a technical requirement that scientists in many countries currently find difficult to achieve.

The "skipping stone" landing is to increase the resistance by friction with the atmosphere after entering the atmosphere for the first time, and then "drill out" of the atmosphere by adjusting the flight trajectory.

At this time, the flight speed has basically been reduced to the first cosmic speed, and then enter the atmosphere for the second time from outer space, gradually slow down during the gradual descent, and finally achieve a smooth landing.

This process is simple to say, but it has extremely high operating technology and technological content.

For example, how to maintain stable flight and effective communication under the high temperature generated by friction, how to choose to change the route at the right time, and at what angle to return to the atmosphere, all of these require precise calculations and accurate control.

The beautiful "performance show" of Venusstar Technology this time allowed Western countries to see that China can master this technology proficiently and can accurately land at a designated location.

If this technology is used in the military, there will be more "missiles" that can accurately destroy targets at more tricky angles and faster speeds.

You know, the hypersonic interceptor missiles used by various countries so far can intercept missiles below Mach 10 at most, and they also need a certain amount of luck. For this kind of "water skipping from the sky", there is currently no effective interception technology and method.

This is why a simple landing caused such a big wave.

"Mr. Cao, you gave us a surprise."

Qian Junfeng called immediately.

To be honest, he only knew that Venusstar Technology's aircraft returned to the earth in this way after watching the video today.

Aerospace technology also knows how to "skip water".

One of the missiles they developed used this special technology.

Aerospace Science and Technology has conducted tests before, and it is difficult for the current anti-missile system to imitate the attack of this "skipping" missile.

Originally, Qian Junfeng thought that this was the unique skill of Aerospace Science and Technology, and no other manufacturer in the world had this level.

But now seeing the scene of the spacecraft of Venusstar Technology returning to the earth, he knew that he had thought too much.

It turned out that Venusstar Technology had mastered this technology unknowingly.

Even from the current situation, it can be speculated that the other party may have mastered it better than Aerospace Science and Technology.

They dared to use this method to recover spacecraft from space.

The most important thing is that the final landing accuracy is surprisingly high, with an error of only about 50 meters.

Not to mention that for intercontinental ballistic missiles carrying nuclear weapons, the error of 50 meters can be ignored.

Even for conventional missiles with large ammunition loads, this error is completely acceptable.

After all, it is a thing launched directly from space.

"Every action we take is to bring various surprises to the world."

"It can't be the Americans who bring us surprises every time. Occasionally we should also give them a little blow."

Cao Yang is very calm now.

They will not admit that they have mastered this special missile technology, but they have demonstrated this technology to everyone.

This is very interesting.

"Isn't your long-term plan for landing on the moon in the future to use starship spacecraft to transport personnel and goods?"

"Why did you use a completely different plan this time?"

Qian Junfeng's question should represent the questions of many people.

The two completely different technical solutions before and after do not seem to come from the same company at all.

The key is that no matter which solution it is, it will bring a huge impact to the world.

The way Venusstar Technology does things is becoming more and more difficult to figure out.

"Different methods have different uses, and we must have multiple options."

"Besides, as the first choice for the moon landing, this method is the most suitable at present. Otherwise, we still need to wait for the test of the starship spacecraft to be completed before we can embark on the moon landing journey."

After Cao Yang's explanation, Qian Junfeng understood a little.

Although Venus Technology is a private enterprise, its requirements for schedule are actually no lower than those of Aerospace Technology.

As long as Cao Yang sets goals for the people below, unless they encounter completely insurmountable difficulties, they must be completed according to the goals.

That kind of situation of just messing around is impossible.

The average age of the entire Venus Technology research team is only in the early thirties.

Whether it is NASA, Polar Bear United Rocket and Space Company, or the European Space Agency and the Indian Space Research Organization, this age is very exaggerated.

Although being young does not necessarily mean that you have enough experience, your drive is very strong.

With the help of the correct direction and the leadership of some experienced old engineers, the achievements of Venus Technology are naturally more and more exaggerated.

"Now that you put it, it seems to make sense."

"I'm looking forward to the moment when your Starship spacecraft lands on the moon."

Qian Junfeng roughly understood what Cao Yang meant, and couldn't help but recall the development of the Starship spacecraft.

According to the plan of Venusstar Technology, they need to conduct at least three tests this year.

Only in this way can they be equipped for formal manned space flight tests.

Compared to the shock on the side of Aerospace Technology, the United States was shocked.

John personally called David from Boeing and Griffin from NASA together, and everyone held a meeting to discuss the impact of this matter.

"David, Boeing is the most important defense contractor in the United States, and many of our missiles are also produced by Boeing."

"There is news that China has successfully tested a certain type of ballistics of "skipping stones" before, and now Venusstar Technology has used this technology to realize the return of the spacecraft to Earth for the first time."

"What this means, I think I don't need to say more, everyone knows it very well."

"When will Boeing be able to come up with similar missile technology?"

John's tone was more serious.

Facing this situation, he was really a little worried.

China has already deployed the air defense missile system produced by Venusstar Technology, which is said to have the world's leading performance.

This means that it will be very difficult for American missiles to shoot at China in the future.

However, China can use the "skipping ball" method to shoot missiles at American territory, but they have no way to intercept it for the time being.

"In the field of hypersonic missiles, we are not completely inactive."

"We also have the technology of skipping balls, but China uses the Qian Xuesen trajectory, while our country uses the Sanger trajectory."

"The main principle of the Sanger trajectory is to let the missile repeatedly jump and skip balls at the edge of the atmosphere, thereby achieving the effect of unpredictable trajectory."

"After multiple jumps, the Sanger trajectory allows the missile to achieve a faster flight speed, but because its trajectory is at the edge of the atmosphere for a long time, it makes it easier for radar to detect and calculate its trajectory, and its concealment is much worse than the Qian Xuesen trajectory used by China."

" Qian Xuesen's trajectory does not strictly follow a parabolic trajectory. "

"Its design principle is that the missile is first boosted by a rocket like a ballistic missile, and after reaching the height of near space, the engine is turned off and the inertia is used for free flight. "

"This mode makes the missile's flight trajectory unpredictable, and the opponent cannot predict the missile's falling direction, so it is not easy to be intercepted. "

"This mode creates a very troublesome situation, that is, the launch site is known, the target is known, but no one knows the running trajectory. "

David felt that he still had to make things clear, otherwise it seemed that Boeing's missile technology was very backward.

In fact, it was not like this.

However, John wanted to know the result now, and he was not particularly interested in the process.

Glenfin, who was standing next to him, knew that John had called him here today, which would definitely not be beneficial.

So he must stand in David's shoes and help a little.

"Why is the Qian Xuesen trajectory adopted by China so difficult to prevent?"

Glenfin's question gave David another chance to explain.

"Traditional ballistic missiles follow parabolic trajectories. They only need to detect a few points in the flight process by early warning radars, and then analyze them with supercomputers to accurately intercept the missiles."

"Although cruise missiles avoid parabolic trajectories, their range is greatly limited due to their excessive reliance on aerodynamics for maneuvering flight."

"Qian Xuesen combined the characteristics of ballistic missiles and cruise missiles and creatively designed the 'boost-glide' trajectory mode."

"This theory was actually proposed in the 1940s, and it is not something innovative."

"It's just that everyone thought there was no way to apply this theory to practice, but China recently broke through this technology."

David sighed helplessly.

His statement is really in line with the facts.

If Boeing knew that this kind of missile could be produced, it would have arranged a large number of people to study it in the early years, and it would not be in a passive situation now.

But there are not so many ifs in this world.

"China's missiles can hit our territory, but our missiles can be prevented by the other side."

"This is completely unacceptable. How long will it take Boeing to produce similar products?"

Obviously, this is the important reason why John called Boeing and Griffin here today.

Find the problem, analyze the problem, and then solve it.

The technical principle of China's "skipping" missile does not seem to be a secret, and many people can easily obtain the relevant research theories.

But it is not so easy to produce it.

David was really a little unsure about John's question.

So he was silent for a long time.

"John, the theoretical direction adopted by China is different from ours. If we want to switch to the same plan as China, we still need to evaluate it internally."

"But conservatively estimated, it will take at least three years."

David knew that he couldn't not reply.

But he didn't want to answer a schedule that Boeing couldn't do at all, because that would lead to endless trouble.

"Venus Technology has caused us too much trouble over the years. We really need to think about how to get along with them."

Granfin sighed beside him, his face full of helplessness.

Fighting doesn't necessarily mean you can win, and even if you win, both sides will suffer.

So what to do in the future, you have to think carefully.
