Chapter 546 Making Money (First Update)

The development of air-to-air missiles has gone through several stages. The first stage requires fighter guidance.

This kind of air-to-air missile is the biggest test for fighter pilots, because whoever escapes first will lose guidance.

The second stage is that as long as the fighter radar locks the target and launches it, it can be ignored.

Most air-to-air missiles of this period were equipped with active radars.

There is also a passive infrared mode, which is also a fire-and-forget mode.

The missile will chase the opponent's infrared target signature, but this missile has proven to have a low hit rate.

It is not uncommon for missiles to be mounted on helicopters. The Comanche can carry a two-meter-long missile, and it is inside the belly of the aircraft.

However, the range of air-to-air missiles is generally relatively long, at least tens of kilometers, so loading air-to-air missiles on helicopters is, at least at this stage, a very bold innovation.

What made Liu Hai curious was what kind of radar this helicopter used.

When many people watch air combat movies, they are curious about why the fighter jet locked by the missile is pulling up like crazy.

In addition to the K47 automatic rifle, carbines and Mosin-Nagant rifles all have a triple scope.

The range is also gradually increasing, which of course is a pain for the soldiers who fire the artillery, because these soldiers have to carry the mortars everywhere.

As long as the missile's fuel is consumed, the missile will be destroyed.

The radar antenna has been deployed, and the huge radar antenna is so conspicuous.

This language is partially similar to the plateau language, but the soldiers don't know which country's language it is.

The anti-artillery radar position is located 5 kilometers away from the shooting range.

Not only Liu Hai is here alone, but there are also several leaders watching from the side.

But it's a pity that Liu Hai can't get close. After all, the air-to-air missile that is being tested, how can Liu Hai get close? Who will be responsible if something goes wrong?

Liu Hai and others came to the shooting range, which is the artillery shooting range.

The leaders all praised in their hearts: Comrade Xiao Liu is calm and composed.

"The error is 6 meters!" These leaders were also surprised when they saw the data compared between the two sides.

"How many artillery shells can be saved with this radar!" These leaders are all military leaders and of course they know the data coordinates provided by this radar.

The artillery radar designed by Liu Hai does not require manual input of elevation data. The Xinbolin radar requires manual input of 8-digit data and then obtains the address of the artillery position.

Go to a place and shoot two shells, then report your coordinates, and then run away quickly.

If Liu Hai knew that he would be praised like this by the leader, he would probably laugh or cry, because for Liu Hai, the error of 6 meters is not surprising, because he has seen more accurate weapons.

Later, the Thunderbolt 5 missile was successfully developed.

In 2020, some missiles have an error of less than 6 meters, not to mention various precision weapons.

Of course, the error of 6 meters is relatively large for Liu Hai, but there is no comparison because there are too many precision-guided weapons when Liu Hai crosses.

And this is only 5 kilometers, so the distance error is 6 meters.

There is definitely an error, it is impossible not to exist, and the farther the distance, the greater the error.

In a certain part of the plateau, a group of soldiers were conducting target practice.

These soldiers held a variety of weapons, including AK47 automatic rifles, Bald Eagle carbines, and early Mosin Nagant rifles.

Of course, Liu Hai also knows that the weapons and equipment at this stage basically rely on quantity, whether it is artillery shells or rockets.

It can save a lot of artillery shells. In the past, it took more than a dozen cannons to fire two or three rounds. Now with specific data, more than a dozen cannons can fire one round each.

The temperature outside is still very cold, but the temperature inside the command vehicle is constant.

Not to mention the error of 6 meters, even the error of 16 meters is still quite different.

Just take this coordinate and compare it with the coordinates of the artillery position in reality.

The process of testing and debugging is very boring, that is, various mortars are fired from a distant shooting range, the radar records the data, and then the coordinates of the artillery position are obtained.

That's because the missile's fuel is limited, so upwards can consume the missile's fuel to the maximum extent.

These soldiers are all from the southwest region and the plateau.

Within 9 seconds of the launch from the artillery position, Liu Hai got the data from the artillery position.

A program is a program, and after the program is completed, actual debugging must be carried out.

In addition to training, these soldiers are also learning another language, but just learning some of the other language is enough.

Of course, it is much more accurate for mortar artillery position detection because the mortar shell speed is low.

For artillery, an error of 6 meters is nothing. A single howitzer can damage more than this area, and as long as the opponent's artillery position is discovered, it will be directly covered by dozens or hundreds of artillery shells.

These leaders were quite excited, but Liu Hai had a calm look on his face.

When these soldiers are running around with mortars.

Liu Hai really wanted to go over and have a look, what type of air-to-air missile is it?

Because Liu Hai seems to remember the failure of the development of the Perak Four air-to-air missile.

Then another test was conducted, with 60 mortars and 80 mortars taking turns.

The radar control vehicle integrates a series of functions such as computer power generation, etc., and of course can also drag the radar antenna.

As for the radar antenna distance, the radar control vehicle has a distance of 30 meters and is connected through a cable. Of course, the distance of the cable connection can be increased. This is to protect the radar control vehicle because there are some anti-radiation missiles specifically targeting radar behind it.

Liu Hai is also responsible for directing the artillery firing at the artillery position.

The plateau is still very cold, and these target shooting soldiers are still quite excited. Although the guys in their hands are a little older, they can shoot bullets after all.

As a soldier, as long as he can shoot a gun, he likes it as long as he has a gun in his hand. Moreover, carbines and Mosingana rifles have triple scopes, making them more exciting to shoot.

In addition to target shooting training, they also need to train mortars and RPGs. What surprised these soldiers most was that they actually had to take a helicopter for rappel training.

There were even some infantry cannons that could be called antiques. Although they were said to be antiques, the shells fired still made the artillerymen very excited.

As for the most basic soil work training, now is not the time.

These soldiers train during the day and undergo language training at night.

Although these soldiers did not understand the purpose of these trainings, most of them knew that there must be action, otherwise how could they have opened up so many things for themselves to create.

It's just that so much hodgepodge of equipment is a bit confusing to the soldiers. Isn't the team doing some standardization and unification? Just to reduce logistical pressure.

Why are you taking out so many old-fashioned things now?

Based on Liu Hai's suggestion, the superior department did not contact anyone in Xijin because they were not sure if there was anyone close to the king there.

However, the railway department has mobilized capable forces to build a road from Kashitse to Yadong. The reason why the railway department is responsible for building this road is because the TBM is under the jurisdiction of the railway department.

The invention of the shield machine has brought great changes to our country in the past few years. Especially when building tunnels, the chance of encountering danger is getting lower and lower.

In the past, tunnel construction relied on manual blasting, which was quite dangerous.

Moreover, artificial blasting will cause certain damage to the mountain. With the shield machine, the safety factor is greatly improved. The shield machine moves in front and the modules are installed behind it.

Of course, many improvements have been made to the modules now. High-strength concrete is used in some high-strength places, and glass fibers and a series of other strength-increasing things are even added to it.

However, the improvement of shield machines is still relatively slow. Today's shield machines are basically controlled by hydraulic and mechanical controls, and electronic control is not yet very realistic.

Hydraulic and mechanical control require more staff.

With electrified control, fewer workers are required.

After so many years of development, the railway department has cultivated mature TBM teams.

The railway department has also established its own research institute to optimize and upgrade all aspects of the shield machine.

Liu Hai tested anti-artillery radar data and optimized the program based on the test data.

At a distance of 25 kilometers, the error for mortar positions reached more than 20 meters, with an average of 23 meters.

This data seems to be relatively normal to Liu Hai. The error of the last 5 kilometers was 6 meters.

Then there are howitzers. The detection error for low-trajectory howitzers is relatively large.

Although Liu Hai was a little dissatisfied, the leaders watching were quite satisfied.

Because generally speaking, artillerymen will first fire a shell to correct the position.

At this time, the anti-battery radar will get the coordinates of the opponent.

Maybe the opponent's artillery position hasn't started firing yet, and the artillery shells here will be shot out and land on the opponent's artillery position.

As for the error of more than 30 meters in 20 kilometers, is this also called an error?

To know how far 30 kilometers is, most howitzers in the 70s only had a range of twenty or thirty kilometers.

That is to say, 30 kilometers has basically reached the shooting limit of the howitzer, and the anti-artillery radar is quite safe at this distance.

The key is Liu Hai's anti-artillery radar, which can also counter rockets.

This made several leaders very excited. In fact, Liu Hai's anti-artillery radar can also detect missiles.

Data can be detected and obtained as long as it is within 30 kilometers.

When Liu Hai tested the anti-artillery radar data and debugged it, the relevant drawings and procedures were sent to the relevant departments for research.

This time Liu Hai only designed and programmed, leaving the rest to other departments, from radar antennas to computer circuit boards.

Therefore, it is quite simple for higher-level departments to copy an anti-artillery radar.

Of course, the cost of current anti-artillery radars is too high. The first is the electronically scanned phased array radar antenna, which is almost entirely handmade in the laboratory.

In addition, there are various chips on computers. Higher-level departments have attached great importance to chips, because the three-axis CNC machine tools designed by Liu Hai use a large number of chips.

The price of purchased chips is too high, and the cost of large-scale use is too high, so the superior department set up relevant departments as early as last year to develop and manufacture our own chips.

Today's semiconductors related to computers are more expensive than gold. There are many chips in a computer cabinet on a radar truck.

Because today's computers use a large amount of the precious metal gold.

Nowadays, the pins of chips are basically gold, even the circuit boards are gold, and the wires are made of silver.

As for why gold and silver are used, it is to increase the life of the entire computer, and the military is to ensure its stability.

Even in modern military equipment, more precious metals are used.

Gold is inherently hard currency, and it is not cheap to produce finished products through complicated processes. Of course, only Liu Hai has the capital to use so many chips to pile up materials.

Nowadays, the most advanced 8080 chip costs 360 US dollars. Of course, the performance is 4004 times higher than that of the 20 chip.

You must know that the average annual income of workers in the Bald Eagle family at this time is only about US$3000.

A chip is equivalent to a month's salary of a Bald Eagle worker, which is still unaffordable.

So it is really expensive to engage in computers now, and the chip update and iteration speed will also accelerate from now on.

The development of chips is very rapid. It only took a few years from the birth of 4004 to the use of 8080. Chip development has since embarked on a fast track. We can still catch up if we can enter the field of chip development at this stage.

In 1974, sales of the 8080 chip skyrocketed and millions of pieces were sold, so the price dropped from $360 to $35.

In other words, the $360 chip you bought earlier will lose 90% of the cost price in the second half of this year.

Of course, this chip will only cost three dollars in the future.

However, Liu Hai is confident that he can catch up with foreign countries in the chip field. He needs a direction and application, and then it is nothing more than burning money.

Of course, Liu Hai's anti-artillery radar can also do many things. It can also be used for artillery calibration, ground and coastal surveillance, helicopter tracking and control, rapid geodesy, and weather balloon tracking.

Although the testing and debugging have not yet been completed, the higher-level departments are already anxiously starting to produce this anti-artillery radar.

At the end of March 1974, Rover Film Company successfully acquired United Artists Film Company, one of the eight major film companies in Hollywood. Liu Hai invested in the shares as two people, Mr. Jack bought 3% of the shares, Mr. Z bought 4.9%, and Liu Hai personally The investment is only US$4.9 million, which means that 500% of the shares are worth US$4.9 million.

Several major Hollywood film companies have been in recession in recent years because they were cut out of a large piece of the pie by Rover.

The entire movie market is just that big. Rover Film Company used Transformers Kung Fu Panda, online and offline combinations, online movies, and offline toy playgrounds to beat other movie companies.

Therefore, only one or two of the major film companies can guarantee profits, while the rest lose money every year.

As a shareholder, there is no need to keep a losing business in your hands.

As for why the share price is 4.9%, it is because of the principle of public announcement and 5% is a threshold.

In other words, Liu Hai actually holds 9.8% of the shares, but as two people invest in the company, there is no need to announce it.

This film company also has a 10% stake held by His Majesty the King, and the rest is held by Rover Corporation.

Then the dealer had another idea for Liu Hai, hoping that Liu Hai would write a script to turn United Artists' losses into a profit.

Of course Liu Hai had no obligation to do so, so every night when he returned home, he would go into the aircraft carrier space to see what movies were easier to make money on.

For Liu Hai, copying a script may only take a few hours, but the income may reach tens of millions of dollars, so why not?
