Chapter 780 The Feeling Is Coming

In terms of entertainment, Liu Hai did not fall into the awkward situation of other movies in the later stages, that is, the later the movies are, the slower they come out.

However, Transformers and Kung Fu Panda have now become one movie every three years, mainly because of the audience's aesthetic fatigue, and Liu Hai wants to open a new pit.

The animated movies Gundam and Toy Story are now one movie every two years, and Liu Hai has opened another movie Ice Age.

Of course, Liu Hai now has a lot of income in the entertainment field, mainly from the derivative copyrights of several major IPs.

Game consoles now occupy an absolute majority. The price of game consoles has dropped due to the development of semiconductors, but only a part of it, because the game screens are becoming more and more sophisticated, resulting in the price of some game consoles rising instead.

Then there is the videotape market, and videotapes are now the mainstream of the market.

When optical discs come out, optical discs will occupy the mainstream again.

Liu Hai is also working on the optical disc project, which is mainly a decoder.

The reason why domestic VCDs were snatched away by foreign countries in history is that the decoder patents are foreign.

Foreign Blu-ray high-definition DVDs still have a lot of market in 2020.

To be honest, the effect of playing this kind of DVD disc is much better than that of most online playback.

After all, the clarity of online playback depends on your network speed and the resolution of your display.

Now the movie box office ranks third, and the toy peripheral ranks fourth.

The main reason is that the game console market is too hot. As for why Liu Hai did not let others come up with the creative ideas for these cartoons, on the one hand, it is a matter of interest, and on the other hand, most of the content and plots are copied anyway, so it doesn’t matter.

In addition, if you let others come up with the creative ideas, you will have to find time to give others suggestions, which will waste time.

Besides, the interests are so attractive that some people may do something else when they see the interests in such a huge IP.

Anyway, the creativity is done by myself now, and the remaining production departments also have separate box office, and everyone counts their own.

The Flying Motorcycle Research Laboratory, of course, it is called the Flying Motorcycle Research Laboratory, but in fact, many things in it are far from the Flying Motorcycle.

For example, the Flying Motorcycle that flies at subsonic speed and has a range of more than 2,000 kilometers.

This thing is definitely a cruise missile.

Another example is the supersonic anti-sea version of the flying scooter, which is a supersonic anti-ship missile.

And Liu Hai's latest flying scooter with a liquid fuel rocket engine, which researchers don't think looks like a flying scooter.

The liquid fuel rocket engine itself has actually been developed, and the key is its brain.

"What are the test results now?" Liu Hai wanted to do the experiment himself, but there was no way.

This test is not a real ignition test, but a test of the sensitivity of the system.

"The sensitivity is still relatively low." The person in charge said.

"Engineer Liu, on the one hand, it is a chip calculation problem, and on the other hand, it is a sensor accuracy problem. This is still a static test. It is difficult to say whether there is a problem with the engine ignition sensor." The person in charge handed the latest test data to Liu Hai while reporting.

Liu Hai nodded. To be honest, it is a bit ahead of time to do this now.

"How about doing an experiment?" After reading the data, Liu Hai felt that he could do an experiment, and if it failed, it would fail.

"It's okay to do the experiment. There are no big problems with taking off and hovering in the air. The key is landing." The person in charge of this project in the laboratory can roughly see what this project is used for?

The project leader could no longer comment on Mr. Liu's idea because it was too advanced.

However, it was not impossible to do this project in person, but the technical difficulty was relatively high.

"Then do a test. Don't make the height too high. Three to five hundred meters will be enough." Liu Hai knew that the most critical thing was to recover the last shiver.

Max had the last shiver that year and fell on his butt.

This involves the sensors, stabilizers, etc. of the entire system.

Because the sensor controls the liquid rocket fuel pump, and then there is a time difference between the thrust change generated by the liquid fuel ejected by the fuel pump.

And there are also big problems with the accuracy of the sensor. The rocket itself is still one and a half meters away from the ground, but his sensor tells him that it is still one and a half meters away, and the consequence is a butt.

Don't underestimate these tens of centimeters. If a rocket is so big and squats on it, it is very dangerous for the various fuel pipelines inside to be damaged.

"What about the anti-buffer system of the landing rack?"

"This also needs to be tested in practice to test the force data that the system can withstand. If the data is too large, it may cause the center of gravity of the entire rocket to shift..." The person in charge spoke again.

"Then we will follow the current design version and find a place to test it. I will report to the factory manager right away."

"But you must be prepared for failure. This is just a small matter now. Later, the rocket will return to the ground from a height of tens of kilometers, which is more difficult." Liu Hai said now, the ultimate goal in the future.

"Engineer Liu, don't worry." The person in charge heard Liu Hai confirm the role of this system and patted his chest to guarantee.

"Okay, you prepare here, remember safety first, and directly start the self-destruction program if there is any danger."

"Yes." The project leader nodded.

Some things need to be tested even though they are known to fail, because the data obtained from actual tests are much more reliable than those in the laboratory.

Of course, this can only be said to be a small gadget now, with a rocket nozzle, and then flying three to five hundred meters high. The overall weight, length, and landing height are very different from the final target.

Generally speaking, rocket recovery is basically at an altitude of about 80 kilometers, and the speed must be controlled when returning from 80 kilometers to the ground.

"Director." Liu Hai came to Sun Aiguo's office.

"Sit down, what do you want to see me for?" Sun Aiguo asked directly.

"The liquid rocket engine project team needs to do an actual test, find a safe place, and find someone to operate it." Liu Hai took a bottle of black tea in the director's office and sat down, then spoke.

"What kind of test site is needed?"

"It's best to be the kind in the ravine, because this thing is quite dangerous. It's mainly a liquid fuel rocket engine motorcycle. I changed the plan halfway." Liu Hai took the responsibility on himself.

"Liquid fuel rocket engines have many shortcomings, and the fuel is very dangerous, which runs counter to the general development direction of flying motorcycles. In addition, the preparation time of the liquid fuel version is relatively long. The filling of liquid fuel is not something that ordinary staff can do. In addition, there are problems with storage."

"What do you plan to change to?"

"I just have a whimsical idea, which is to recover the launch vehicle."

"Ahem, ahem!" Sun Aiguo knew that the launch vehicle, which was dozens of meters high and several meters thick, had to be recovered, and he was so scared that he choked on the water.

"Look at how scared you are." Liu Hai stood up and patted Sun Aiguo on the back.

"How do you say to recover it? Collect waste?" Sun Aiguo still couldn't understand this, although he knew that the rocket debris would fall to the ground, because the motorcycle factory had previously produced these helicopters specifically to find and recover rocket debris, because these things usually fell in sparsely populated areas, and were brought back by helicopter after being found.

In addition, the thing looked big, but it was very light, so it was quite dangerous when the helicopter was hoisted.

"The launch vehicle is generally a three-stage structure. The first stage is mainly responsible for sending the second stage and the third stage of the cargo compartment to an altitude of more than 80 kilometers, and making the second and third stages reach a speed that escapes the earth's gravity."

"The main cost of the rocket is the first stage. What I mean is that the first stage sends the upper part to 80 kilometers, then comes back and lands at our recovery site, and then the recovered part is inspected and maintained and used for the second time."

Hearing Liu Hai say this, Sun Aiguo immediately found the feeling, that is, the feeling that he seems to understand after listening, but does not fully understand. Every time Liu Hai says this, it is definitely a big deal.

"Oh, oh, that is to say, it is equivalent to recovering the most valuable part, and then using it twice or three times later?" Sun Aiguo looked like he understood.

"That's the ultimate goal, but now it's just a preliminary test. It can only fly 300-500 meters high and then fall down, and it still fails 100%. The main purpose is to collect some data."

"That means your current experiment is to send this thing to 300-500 meters high and then recover it?"

"It's probably like this, but because of the data problems of the controller and the control system, as well as the accuracy problems, it may fall to the ground and explode when it is recovered."

"So a safe test environment is needed, and professional personnel are needed to operate it, after all, it involves liquid fuel."

Sun Aiguo nodded immediately after hearing this: "It seems that this can only be done by the superior department?"

"That is to find a professional department, and also let them see if our design has a future?" Liu Hai said modestly.

"If you fail, you fail. I think you have a future when you say this. Don't believe others. Who is as capable as you?"

"The leader praised me."

"Oh, I'm going to retire in one or two years, but I didn't expect you to do another big project."

"Tell me what the significance of this project is if it succeeds?"

"The cost of launching a satellite in the future can be used to launch 5 or even more satellites. After the satellite is launched, it will be like selling cabbage."

"This is good, this is good. Satellites are good things."

"This is our test plan." Liu Hai brought the plan with him, because he knew that the factory director didn't understand it.

Of course, the leaders of the superior department didn't understand it very well, so Sun Aiguo took Liu Hai's plan to the leader of the rocket launch department.

"Liu Gong, this is really something." The leader of the department read the plan carefully.

"In fact, our department had this idea before, but it didn't start for various reasons. I didn't expect you to start it, and it's going to be tested soon." Although the leaders of the department didn't understand the meaning of technology, they could still understand it from an economic perspective.

"Xiao Liu's test this time is somewhat dangerous. In addition, the current test is just a preliminary test. The flight altitude and flight weight cannot be compared with the final goal." Sun Aiguo said nothing else, but he still has the ability to understand.

"Of course, I will ask the people below to cooperate immediately." The leader in charge of the rocket launch department certainly knew it.

"Okay, after you are ready, we will discuss it together." Sun Aiguo nodded.

Of course, this plan only mentioned the test plan, and the leader in charge of the rocket launch department did not see the real thing, but Liu Hai's reputation was not mentioned.

The rocket launch department quickly organized a team of capable people to form a special team, and the test was arranged in the mountains of Zhangjiakou.

Because this kind of thing is not suitable for testing at the rocket base, it is easy to fly up, and it may also be easy to fall down.

Bang... Boom!

The rocket launch department directly prepared a test site in the mountain, because it is foreseeable that there will be more than one test.

Of course, Liu Hai can't participate in this kind of business, so Liu Hai asked the project leader to be responsible, anyway, a lot of work is done by others.

The rocket engine and the overall hardware and software are all made in the motorcycle factory.

The rocket launch department responded quickly and completed the test site in half a month. This project team has also communicated with the rocket engine project team of the motorcycle factory.

The risks involved are still very large. The first is the fuel injection. The fuel tank project team adopted Liu Hai's suggestion and did not use the vacuum mode, but the inert gas mode.

In the history, when we conducted the Dongfeng test for the first time, the missile body was dented because the fuel tank was in a vacuum, so it would deform under external pressure.

Because we want to recycle and use it, the deformation of the tank will cause metal fatigue, which is absolutely not acceptable, so inert gas is injected.

After the inert gas is injected, the inert gas must be discharged along with the fuel delivery.

This is a completely new technical problem, especially for the rocket launch department.

There is another problem, that is, if the fuel in the fuel tank is successfully recovered, inert gas must also be injected during the recovery.

Of course, if it comes back too fast and falls to the ground and turns into ash directly, there is no need to consider this.

In addition, the overall stability after recovery must be considered. Although the laboratory of the motorcycle factory has a theoretical solution, no one has done the specific implementation.

So although the test site was built in half a month, if you want to test it, you still need to further understand the technology.

Liu Hai also knows that there are many new technologies, including the coating inside the tank, that is, corrosion-resistant coating, because liquid fuels are all corrosive. If you want these fuel tanks to be reused, you must prepare for corrosion protection.

Of course, this project is top secret. The most eye-catching thing now is the J-10 fighter jet, because it takes off more and more frequently, and in April, people in the suburbs east of Kyoto can occasionally hear a deafening sound, like thunder.

Many chickens and ducks of farmers there were scared to death. The farmers didn't know what it was and thought it was a dry thunder. Later, the government calculated the compensation and found out that it was caused by the plane flying too fast in the sky.

This is a hammer, a supersonic twin-engine, two-seat heavy fighter, but the attitude of the Western media made Liu Hai confused, because they were praising our military technology, which seemed a bit exaggerated to Liu Hai, but he didn't expect that the exaggerated was almost the same.

"Should it be to disgust the fat bear?" Liu Hai looked at the data written on the Western media, and it was almost like saying that this plane beat all your fighter jets.
