The main goal of Bang Hai was to start copying drawings while directing the work of the scroll shaft workshop.

The people in the courtyard were also very surprised that Liu Hai drove a new car, but after Liu Hai drove a new car, he never brought other people in the courtyard to work with him.

Liu Hai was a little late because he got off work late at night, and Liu Hai was a little late in the morning, and there was no one to supervise Liu Hai anyway.

The main reason is that Liu Hai feels that the new car is a little uncomfortable to pull people to and from work for free, the key is that some things become a habit when they are done, and Liu Hai himself does not smoke, and now many workers smoke, and they smoke for others when they get in the car.

If someone smokes in the car, Liu Hai feels that there is a smell of smoke in the car for several days.

No one is allowed to smoke in Bangs' office, whether it's in the maintenance department, the yacht building workshop, or now the turboshaft engine manufacturing workshop.

Sun Aiguo has to come to the turboshaft workshop every day to walk around, and he also knows that Liu Hai is making the design drawings of the helicopter.

At the same time, Liu Hai also oversees the production of two films, Transformers Part 3 and Kung Fu Panda Part 2.

This is not very time-consuming, that is, every once in a while they send in samples, and then Bang Hai gives opinions.

"Lao Mei later found out that their helicopter is still very different from the helicopter I designed." Liu Hai knew that the old American Black Hawk helicopter was only finalized in 1974, and the shape of the helicopter at the beginning was very different from the current design of his own design.

As far as the overall appearance is concerned, Lao Mei has also changed many times, whether it is the window or various other places.

"I can be finalized in seven or three years, Lao Mei will take seven or four years to finalize, and it is estimated that we will all be in service in seventy-four years!"

"The next step is to make artillery radars." Bangs now makes drawings during the day, works overtime for two hours at night, and rests the rest.

The reason why Liu Hai wants to make artillery radar is because artillery radar is the most helpful to us at this stage.

"Historically, the Simberlin radar we imported can only be regarded as a mortar radar accurately, and for faster howitzers, the response is a little slow, and the accuracy is very low."

"The Simberlin radar is divided into type one and two, the first type is the towed type, and the second type is the self-propelled type."

"That is, the first type is like a towing artillery, which is directly towed by a truck, and the second type is placed on an armored vehicle."

"The third type derived later was changed to an electrical scanning phased array antenna system, and I made this similar one."

"At the same time, there is also the AN/TPQ36/37 artillery radar developed by Laomei."

"Lao Mei seems to have started developing it this year, but I won't start working on it until next year, but if the current semiconductor technology is to make an electrical scanning phased array, the antenna system will be relatively large." Liu Hai carefully recalled things about artillery radar, of course, some weapons magazines on the aircraft carrier also introduced it, and there were some related professional books, and there were also many radars on the aircraft carrier.

Our country's phased array radar can be said to have reached the point of abuse when the bangs are crossed, the drone is equipped with an active phased array radar, and a phased array radar is used to detect wild boars, and the whole thing is only thirty kilograms.

And it is possible to clearly distinguish wild boars from other wild beasts, imagine that a thirty-kilogram phased array radar placed on a mountain can detect whether there are wild boars in a large cornfield or orchard?

How useful would this be if it were used in warfare?

"Of course, the detection range of the radar is related to its own size and power, and the ballistic missile radar monitoring system manufactured by the United States and Big Brother at this stage requires several power stations to provide power for a radar."

"However, relatively speaking, the artillery radar is relatively simple, and it only needs to detect the two points of the trajectory of the shell, and you can calculate the opponent's artillery position."

"The maximum detection range of artillery radar is 100 kilometers, which is the best."

"If you want to say that the trouble is the radar on the ship and the fighter, that thing is not only a detection range of hundreds of kilometers, but the fighter radar also has the ability to scan downward, as well as the ability to filter, but also the ability to track multiple targets."

"It's the same with surface ships."

"However, on my side, it can only be regarded as a sample, and the subsequent miniaturization and getting on the plane, the ship completely depends on the ability of the relevant departments." In the space of the aircraft carrier, Liu Hai began to think about making artillery radar while looking at radar-related things.

"However, due to the current manufacturing technology, I am afraid that it will be relatively large when the time comes."

"But it doesn't matter, there is no small artillery radar in the first place."

"My own artillery radar is the first generation, which is to simply calculate the opponent's trajectory and the coordinates of the artillery position, and there is no need to have the ability to guide the attack like the artillery radar in the back."

"The big deal is that two more people are enough."

"But in the later war, the artillery radar slowly lost its effect, Ermao got a batch of artillery radar from the old United States at that time, although the model is a little older, but on the battlefield was directly blown up by the opponent's air motorcycle."

"The main thing is the core data model, and if the data model is done well, the faster the calculation results." The calculation model of the radar calculates the coordinates of the opponent based on the detection data input by the radar.

The artillery shell is a parabola, and the artillery radar can calculate the coordinates of the opponent's firing position by obtaining the data of the two points of the parabola of this shell.

Of course, artillery radar also has shortcomings, even if it is the electrical scanning phased array radar system designed by Liu Hai now, for low-trajectory howitzer shells, the calculation accuracy is very low.

As for the current mainstream artillery radar, basically only mortar shells, this kind of low-speed artillery shell trajectory calculation is more accurate.

"It is necessary to look at the current level of radar manufacturing in China." Bangs decided to figure this out first.

So when Sun Aiguo came to the turboshaft engine workshop the next day.

"Director, I have something I want to trouble you here." Liu Hai called the factory director to the office and then spoke.

"What is needed." Sun Aiguo still thinks that Liu Hai needs anything in engine manufacturing?

"I want to know the current level of radar manufacturing technology in China, and when designing helicopters, reserve the location of the radar." Bangs made an excuse.

"In particular, I saw the information sent by my superiors about the technology of phased array radar." Liu Hai said, because phased array radar technology was actually proposed a long time ago, probably decades earlier than now.

It is only limited by the development of semiconductor technology, which has developed rapidly since the sixties, from large radar arrays, then to ships to aircraft.

The faster the development of semiconductors, the smaller and smaller phased array radars will become, and the technical level will be higher and higher.

Bangs should know the current domestic manufacturing technology, and then design.

Whether it is the traction type of Lao Mei, or the self-propelled type of Zoo No. 1 made behind Big Brother.

The Zoo No. 1 artillery radar made behind Big Brother is to put the radar antenna on top of the mobile armor, fold the antenna when it is not in use, and erect it directly when it is used.

The old United States is a traction type, and traction has an advantage, that is, the power generation vehicle and personnel are far away from the antenna.

The antenna can be placed more than ten meters away and connected with a cable, so that even if the antenna is hit, it will cause minimal damage to personnel.

"Of course no problem, I'll help you find it later, when will the turboshaft engine be tested?" Although Sun Aiguo came to see it every day, he never asked about the progress of his bangs.

"We have had a turboshaft engine manufacturing experience, and we will be able to start testing it in the middle to late next month." Bangs spoke.

Of course, Sun Aiguo knew that he was talking about the Little Antelope helicopter imported from the cottage in the past.

"What about the helicopter parameters this time?" Sun Aiguo is most concerned about this now.

"You can seat a dozen people at a time, and each of these two turboshaft engines has more than 1,000 horsepower." The bangs did not say anything about the detailed technique.

"In terms of rotor manufacturing, I also have some ideas." Bangs are ready to come up with the rotor manufacturing design technology of the Black Hawk helicopter.

"If you have an idea, put it forward, I'll report it, according to the parameters you designed, then this helicopter, let's build it ourselves in the future?" Sun Aiguo feels that this helicopter is suitable for the identity of the motorcycle factory.

"This is up to the factory director's arrangement." Liu Hai didn't think it was necessary, but the factory director said so, Liu Hai definitely couldn't refute it, as long as he came up with better helicopter manufacturing technology later, then the factory director would definitely let this out.

Bangs feel like helicopter manufacturing, you still have to have two or three factories to be competitive.

There is no competitiveness in making it in a factory alone, anyway, if you are not satisfied, you have to buy it, even if there is no progress in ten or twenty years of equipment on my side, you don't want to buy me.

If there are two or three companies competing, then it will be better for the overall technology development.

"In the future, I also plan to design helicopters with higher load capacity and professional armed helicopters, you can always look at this helicopter." The information that Liu Hai took out here was the Cobra gunship that he had collected before.

Cobra gunship began to redefine gunship, before the Cobra gunship came out, adding cannons, rockets, machine guns to other general-purpose helicopters could be called gunships.

After the Cobra gunship came out, the general-purpose helicopter and the gunship were truly distinguished.

Cobra helicopters began to equip the troops of the old United States in six or seven years.

Some of the information obtained by Liu Hai is recorded on it, and there are even photos of the plane.

A lot of the information on Liuhai's side is given by the superior department, and the superior department is mostly collected through dealers.

Of course, the dealers give more information about Lao Mei, and it is impossible to give it to themselves.

Besides, the helicopter can't be kept secret, after all, it has to fly around a lot.

Sun Aiguo looked at the domineering appearance of the gunship, and swallowed his saliva, how many weapons are there on this thing?

"Yes, it must be done." Sun Aiguo looked at the helicopter gunship, and instantly threw aside the helicopter that Liu Hai just said was transporting people.

Liu Hai smiled in his heart, his factory director is a veteran, and he still likes this kind of weapon-like thing.

"When our transport helicopter accumulates enough technology, the next step will be to do it, but the armed helicopter involves radar, missiles, rockets, fire control systems, etc., and the factory director needs to get more information in this regard." Bangs spoke again.

Sun Aiguo nodded, as long as the information is needed on Liu Hai's side, the higher-level departments will meet it, except for the core mushroom technology and the like, of course.

Bang Hai is also going to start working on helicopter missiles here, isn't it a seeker plus a solid rocket, plus a warhead?

It's not a very complicated thing.

In addition, Bang Hai is ready to engage in air scooters, of course, this thing can only be inertial guidance, which can be understood as a cannonball with wings.

Now there is no GPS either, and there is no remote control system, only inertial guidance.

Of course, inertial guidance also has its advantages, that is, it has strong anti-interference ability.

Global positioning systems (GPS) and remote control systems are susceptible to interference by electronic jamming systems.

And the key is the global positioning system, if it's your own, it's okay to say, if you use someone else's, you can pinch it at any time, or even change the data and let the missile hit yourself.

And the most critical thing is that if you use someone else's chip, it is also very likely to drop the chain at a critical time.

"I'll go to my superiors right away when I turn around." Sun Aiguo said directly to Liu Hai.

"Then it's going to be a trouble for the factory director." Bangs smiled.

"It's just hard for you, and you have to command the people outside to work, and you have to make a map here." Sun Aiguo felt that the bangs were too desperate.

"Strive for our helicopter to come out early, it's okay for me to work hard." Bangs shook his head.

"Well, your sci-fi dealers have decided to publish it, and they're very optimistic about it, and they're supposedly going to make a movie."

"Magic makes live-action movies, and the dealers don't find good candidates, mainly because they are worried about the shooting effect, and no director dares to guarantee that it can reach the level of the illustrations in you." Sun Aiguo told Liu Hai two more news.

"Whatever they do." For the dealer's approach, Liu Hai has no opinion, and there is nothing to do.

As long as you can make money from publishing, you can do it.

Liu Hai has to touch the bottom of the semiconductor side first, if not, when the quarter is divided, he will tilt a part of the funds towards semiconductor research.

When the helicopter is finished and the artillery radar is made next year, there will definitely be some breakthroughs.

When the antenna is made smaller, the transmitter power can be smaller, and the whole can also be smaller.

Otherwise, you can only make it bigger, of course, Bang Hai's personal feeling, it doesn't matter if the artillery radar is big or small.

It's just that after the radar is miniaturized, it is good for getting on ships and planes.

"That's right, they're professional." Sun Aiguo nodded.

Sun Aiguo hurriedly went to the higher authorities for support.

And Liu Hai scratched his head: "It looks like I'm going to have to work with a helicopter bar for several years." ”

There are still many categories of helicopters, in addition to super stallion helicopters, gunships, and small bird helicopters that are preferred by special forces.

In the movie Black Hawk Down, the performance of the Little Bird helicopter is very amazing.

Instead, Black Hawk was hit by an enemy RPG because he was about to hover and rappel.

The special forces of the United States like this kind of Bird helicopter because of its low noise and low infrared signature.

In this movie, because of its small size, the Little Bird helicopter landed directly on the street, put the personnel down and took off, but did not suffer losses.

Of course, this movie is shot based on real events, in fact, when it comes to the bangs crossing, the helicopter's survival environment is very difficult.

The main thing is that there are too many ground air defense weapons, all sorts, and the most troublesome thing is individual air defense weapons, and you don't know where the other side is coming from.

Not to mention the helicopter, even when the bangs are crossed, the living environment of the fighter is worrying, and if it is not good, it may be locked by air defense weapons.

At that time, people's equipment was more dangerous, because there were drones in the air at any time.

However, at this stage, these military equipment are still very useful, and Liu Hai feels that he should lower his vision a little and not look too far.

Otherwise, it doesn't feel interesting to see any weapons and equipment collapse.

Sun Aiguo came to the higher department and said Liu Hai's request.

"You're already building helicopters?" The leaders of the higher departments were a little surprised.

"Experiments, experiments." Sun Aiguo forgot to report the recent situation to the higher authorities.

However, Sun Aiguo's words also make sense, because the following report will still be reported to a certain extent.

It's too early, and the report may be empty, and there will be a lot of joy.

"Are there any specific parameters?" The head of the higher department was very concerned about the matter of helicopters.

Because at the present stage, helicopters are very versatile, especially for armored forces, which have great advantages.

To put it bluntly, there is a great advantage over tanks.

Although our tank technology is not bad, and there are assault vehicles, but in the face of the steel torrent of Big Brother, there must always be enough restraint.

"This is not available for the time being, we are manufacturing engines, and Comrade Xiao Liu's helicopter has not yet been designed." Sun Aiguo shook his head.

"But Comrade Xiao Liu said that ten people can be seated." Sun Aiguo added.

"This matter must be reported frequently, we have an urgent need for this kind of helicopter, I don't know how their helicopter factory is doing, there has been no technological breakthrough in the past few years." When the leader of the superior department said this, he had a somewhat complaining tone.

Sun Aiguo smiled, now Sun Aiguo doesn't understand, it's too difficult to break through such a difficult thing as a helicopter.

The leader of the higher-level department said: "It still depends on Comrade Xiao Liu, but his thinking, we really can't compare, and the science fiction he wrote is incredible." ”

When Sun Aiguo heard this, he rubbed his forehead: "Anyway, I've watched it several times, but I still can't understand some of the things in it." ”

The leader of the higher-level department smiled: "Look at Comrade Xiao Liu's science fiction, I don't have any knowledge, but I can't understand it." ”

When Sun Aiguo heard this, he didn't feel good, so he took the cigarette on the table of the leader of the superior department in his hand: "I'm the big boss, but I can just manage people, who let us have a Comrade Xiao Liu in the factory." ”

Then Sun Aiguo left with the cigarettes of the leaders of the higher departments, and the leaders of the higher departments shook their heads when they watched Sun Aiguo leave.
