Under the instructions of Chen Weidong and Lin Zeju, both domestic and African bases have been making various preparations for the utopian plan for several years.

They fought in the mall, earning back large sums of money, which strongly supported the smooth progress of the utopian plan.

Including at the press conference, the spokesman declared that this was only a preliminary test of lunar exploration, and that the aerospace aircraft was far from being perfected.

But in fact, not to mention the three-year-long data flight test of the 10-meter reduced data collection machine organized by Zhao Gong and others in the southwest region.

It is this 98-meter full-scale verification aircraft, and there are more than once or twice for take-off, landing, and low-altitude performance tests.

It's just that because the demonstrator has never reached the middle and high altitudes, and between the mountains in the southwest, it is difficult for foreign long-range radars to detect targets at such a long distance and in complex terrain conditions.

It was not detected by the national monitoring station.

Now, the reckless mountains of the southwest have become a secret base for Infinity Corporation, which specializes in testing heavy equipment.

A few years ago, the site was just a river valley.

The water brings with it an abundance of mud and gravel, which reverberates through the valley and settles down, gradually filling the valley into a gentle valley.

Engineers repaired the mouth of the valley and built a dam to prevent the river from backing up during the rainy season.

Later, they re-leveled the land in the valley and built factories and dormitories.

The hermetically sealed environment of the valley floor, which resembles a basin, is an excellent location for the construction of a secret factory.

In order to transport supplies, the military also deliberately allocated a lot of manpower and material resources to build an asphalt road leading to the outside of the mountain.

There are soldiers stationed along the road, who are responsible for checking the road conditions along the way, so as to repair and maintain the road in time and ensure the smooth entry and exit of materials.

This winding path, which is more than ten meters wide, is the only way to keep in touch with the secret factory and the outside of the mountain.

At the location of Taniguchi, there is a battalion of soldiers stationed here all year round.

All people entering and leaving must wear identification signs, and all of them have complete files, and strangers should not think of entering the valley even if they have a letter of introduction from the province or military sub-district.

If anyone dares to break in, they will definitely be killed on the spot.

From here, every five hundred meters, a cordon is set up.

There are three such cordons.

In addition to light firepower, there are also wheeled armored vehicles, transport helicopters and other heavy equipment.

The surrounding hills are all equipped with guard posts, telephone lines criss-cross, and surveillance cameras are all over the hills, 360 degrees, and there are no dead ends in all directions.

Thirty kilometers away from the valley, there are two ground-based radar stations, which monitor the sky.

More than a dozen sets of anti-aircraft missile positions, scattered around the valley.

Anti-aircraft positions, antiaircraft artillery positions, and individual air defense missiles have formed an air defense system with high and low combinations.

Although there is no air force fighter to protect them, in the southern theater hundreds of kilometers away, two squadrons of newly reequipped Jian-10 fighters are ready to sit back and wait at any time.

Every day, there will be two planes on duty, hovering over the southwestern mountains, and they are known as familiar equipment.

In fact, as long as they give an order, they can rush to the sky above the base within ten minutes to provide air cover.

With such tight protection, unless the enemy uses long-range nuclear missiles to attack, no one can shake the base in the slightest.

Moreover, over the years, the engineers have blasted the belly of the mountain, preparing to hollow out the interior of the mountain.

Once the whole project is completed, the lead-iron alloy gate that is several meters thick is closed, and it is a nuclear bomb attack, and I am afraid that the production base will not be erased from the map.

Such a tight protection has never been seen before.

What exactly are they protecting?

The answer was soon revealed.

Under the protection of a large number of pilot vehicles and guard vehicles, 50-wheeled heavy military trucks slowly moved into the base in the night.

Unloaded from the truck

The machine is as small as seven or eight meters square, and as large as tens of meters.

And these are just some parts of a complete machine!

The parts were carefully transported to the factory by technicians and installed under the guidance of another group of personnel in dark blue uniforms.

The time for the delivery of spare parts was all arranged in the evening, and the time when the American satellite was in the sky was calculated and quietly delivered in place.

This process lasted for two or three months.

Under the guidance of engineering and technical experts of Infinity Company, the installation of huge machine tools, plus post-commissioning and precision calibration, is the initial installation of these large machine tools.

So far, this is the core of Huaxia's military industry.

Tank turret?

Cast and molded in one go!

Large aircraft engines?

No problem!

Dedicated production line, no need to change the machine tool, can be completed in one time.

In the absence of a better alloy formulation, the strength of the engine increased by 10 to 10 percent.

Fuel consumption has been greatly improved, and the time spent in the air has been greatly improved.

The service life has jumped from hundreds of hours to nearly 1,000 hours.

It greatly extends the service life of military equipment in peacetime and reduces the cost of armament maintenance.

Submarine propeller, a new type of high-precision super-large machine tool equipment, processed submarine propulsion propeller blades, so that when the submarine is traveling on the seabed, the dynamic propulsion noise is reduced to less than 80 decibels.

Completely masked by the waves of the ocean and the noise of life under the sea, the enemy's underwater sonar is impossible to detect.

Rocket engines, large warship keels, fighter shell casting....

With the continuous operation of the base, from the initial single-piece trial production, to the medium-term small-batch processing, to the later stage, the three armed forces lined up to send one after another large military products to be manufactured here.

This base has officially played the role of the core of China's military industry.

The J-10 is still the same J-10, but its improved engine gives it more power.

The take-off weight has been increased from 13 tons to 17 tons, which is an increase of more than 4 tons.

The strong power support has greatly improved the fighter's climb ability and turning radius, and the flexibility of air combat has become more prominent.

If it is said that the performance of the J-10 has been equivalent to F before, there is a factor of psychological comfort in this, but the modified J-10 is not inferior to F in terms of its air combat performance.

In addition, a new model of nuclear-powered attack submarine, its shell casting and blades, are also trial-produced by the mechanical department of Infinity in this foundry base.

After the final assembly and launching, the results of the test were extremely satisfactory to the Navy.

Later, during combat readiness patrols, this type of submarine suddenly surfaced without warning and appeared in front of the opposing fleet from the front of the Japanese fleet that had "strayed" into our waters on several occasions.

Scared them out of a cold sweat and avoided the sea.

In the official report document of the other party, this new model of submarine is called a "ghost submarine".

Wandering in the deep sea, without a trace, without a trace, elusive, untraceable.

The military's strategic nuclear submarine on duty, after making a test boat and testing it for another year, handed over the remaining shell and blade manufacturing tasks to the Infinity Company's large-scale equipment casting base.

The military's large-scale weapon systems, manufactured by Infinity's ultra-high-precision equipment, have made a huge leap forward in overall performance.

The Japanese exclaimed, "Overnight, Huaxia's military strength has risen to a new level!"

This greatly deterred those with ill-intentioned intentions who might take a risk.

In 2010, the mountainside project was completed.

The engineers used tNt to blast out a huge space and extend it all the way to the ground, comprehensively staggering up to dozens of square kilometers.

The thickest

Places, up to two or three kilometers, and the weakest places, too, have a kilometer or two, which is enough to withstand a frontal attack from a nuclear bomb.

Inside, there are more than 10 large-scale workshops, including engine casting workshops, large-scale deformation equipment manufacturing workshops, and special equipment manufacturing workshops.

Each workshop is divided according to the level.

In total, it can accommodate tens of thousands of people to work, live and rest in it.

The new casting base adopts the operation of eight hours and three shifts, and after the handover of each shift at the entrance of the hole, the lead-iron alloy gate with a thickness of eight meters will be driven by a high-power motor and slowly closed to prevent sudden conditions.

There is an air filtration system inside the mountain, and it is connected to groundwater, and a large amount of food and equipment is stored.

In a critical moment that may be encountered, the cave can also ensure that 20,000 people will not be harmed by the external environment within a year.

After the factory was relocated to the heart of the mountain, the temporary factory building outside was vacant.

However, it has only been vacant for less than half a year, and new personnel have arrived.

This is the aerospace aircraft test team led by Zhao Gong.

They kept a factory near the hill wall, and the rest of the buildings were demolished and filled.

After that, high-grade cement was brought from outside the mountain to build a 10-kilometer-long ultra-long runway.

The data collector used to test the data is only about one-tenth of its full size and is more than ten meters long.

However, due to the fact that the aerospace aircraft must ensure hypersonic flight, it cannot adopt the shape design of conventional aircraft, and the wingspan is too long, which will form a strong resistance during flight.

Therefore, this aerospace aircraft designed by Infinity uses hypersonic aerodynamics, the so-called "ascending body".

i.e., blunt-headed triangles.

When flying at hypersonic speed, the aircraft with this shape design will form an upward lifting force, reducing power consumption and saving energy.

However, the wingspan of the fuselage of this aircraft is too small, so when taking off with conventional turbine drive, a longer runway is required.

Moreover, due to the excessive size of the aircraft and the use of a new alloy formula, the full-size verification machine itself weighed 120 tons.

The lifting and landing support frame and sliding tires alone must be specially made.

And in the belly position, a special reinforcement design has also been made.

This kind of aircraft has no way to take off and land on a conventional runway, and can only take off and land on a specially made ultra-high-grade runway.

Just the paved runway reached . Thickness of meters!

For this alone, the cost of this runway has reached more than 300 million yuan!

The aircraft adopts a combination of ground remote control flight and artificial intelligence piloting.

They specially borrowed a Jian-10 from the Air Force for modification, dismantled the weapon system, installed a remote-controlled gondola, and the operator flew remotely in the back seat.

There is no way around it.

The composite engine used by the aerospace aircraft uses a turbine when taking off, and when it reaches Mach 4, it can be accelerated for a short time by a rocket engine to reach a speed of more than Mach 7 before the scramjet engine can be started.

And once activated, his speed can suddenly increase to a dozens, or even twenty or thirty Machs.

Radio wave tracing will be extremely hard.

Even if the high-altitude remote control of the J-10 is adopted, it can only fly to the high altitude in advance, and the method of segmented remote control is used to ensure that the aircraft will not get out of control.

As for the ceiling, it is not a problem, the maximum ceiling of the J-10 has reached an ultra-high altitude of 18 kilometers.

The normal take-off altitude of an aerospace aircraft, which is this altitude.

Further up, it can only be boosted by rocket engines to break out of the thin atmosphere.

After going up hundreds of kilometers, it comes to the low-earth orbit to levitate, and then through orbit correction and maneuvering to increase its speed relative to the blue star, it can really get rid of the gravitational pull of the planet and enter outer space and space.

Just casually speaking, the technology involved in this is already very complex.

Actually, at the base in Africa

Researchers have tested various indicators of aerospace aircraft in a simulated environment, and have made tens of thousands of improved designs.

This is an advantage that no other country, or scientific research organization, can match.

In a near-real-world physical environment, find design vulnerabilities that can cause fatal flaws in advance, then improve them, or redesign them.

In the research process of other aircraft, it takes several years or even more than ten years of repeated flight tests to master some key data.

In this process, it is not uncommon for test aircraft to crash due to design flaws.

In order to find the cause of the crash, the designers had to rebuild a new verification machine with the same defects to find out what was wrong with the accident.

It's no surprise that a study has been tossed and turned, and that a study has been stuck on and off for a long time.

While foreign researchers are still having a headache for the high cost of experiments and the slow progress of research, the researchers in the African base have already obtained all the arguments in the virtual environment.

All they spend is their ingenuity and some electricity consumption.

If it weren't for the fact that human scientific understanding is far from enough, and the virtual environment cannot achieve % perfect simulation, the African base would not need to conduct actual tests at all to finalize and produce prototypes.

Even so, it is also a testing machine for initial data collection.

Zhao Gong and the prototype they made, in addition to being only one-tenth of the full size, from the core to the technology, as well as the extremely mature, and the final finalized actual machine style, there is not much difference.

The only difference between this aircraft and real people is that it uses intelligent remote control.

Inside, there are three photonic processor chips, which build an intelligent flight assistance system.

The control center is equipped with a miniature version of the Tiandao intelligent system.

The remote controller only needs to give a simple command, such as take-off, landing, hovering, flying upward, etc., and the intelligent system will make a certain autonomous response according to the preset program.

According to the flight status and handling performance of the aircraft at that time, it is executed according to the instructions.

Zhao Gong and they were very careful, and each project went through dozens or hundreds of tests before moving on to the next one.

Infinity's large foundry in the southwest has seen its once-peaceful valley become a busy airport.

Every day, you can hear the sound of supersonic speed breaking through the sky, far and near, rumbling through the sky.

In those years, the intelligence department also intercepted the children of several employees, secretly took photos of the aircraft, and attempted to post them on the Internet, and immediately gave very severe punishment.

People endured the noise caused by the harsh supersonic sound barrier for more than two years.

Then, when they woke up one day, they suddenly found that the voice that bothered them every day had suddenly disappeared.

The factories in the valley are still there, and the runway is still straight and straight.

However, the dark blue uniforms who laughed and danced around a model airplane like children every day were gone.

It's as if they never came.
