The new engine J-10 has been modified, and its excellent performance has been recognized by the assembly. The new model of the double-engine J-10 b,:|.|Motivation. Southwest Aircraft Group Corporation has made bold statements to make the double-engine J-10 reach or even exceed the F15 level!

A new model of ground-powered attack submarine, its shell casting and blades, were all trial-produced by the large equipment casting base of Huanyu Company.

After the final assembly and launch, the test results made the Navy extremely satisfied. After that, during the combat readiness patrol, this type of submarine suddenly floated up from the front of the US and Japanese fleets that "erroneously entered" the Chinese waters, without warning, and appeared in front of the other fleet, which scared the US and Japanese fleets into a cold sweat, thus avoiding this sea area far away.

In the official reporting documents of the United States and Japan, this new model of submarine, called the "ghost submarine", wandered in the deep sea, coming without a trace, leaving without a shadow, elusive and unable to trace.

The military's strategic nuclear submarine made a test boat. After a year of testing, it also handed over the remaining shell and blade manufacturing tasks to the large equipment casting base of Huanyu Company.

The large-scale weapon system of the Chinese military has made a leap in overall performance through the manufacturing of Universal's ultra-high precision casting equipment.

The United States and Japan exclaimed, "On the whole country's military strength rose by a full step overnight", which greatly shocked those who had ulterior motives and might take risks.

By two thousand years, the mountain belly project was completed, and the engineers used TNT, a huge space, and extended to the ground, crisscrossing dozens of square kilometers. The thickest place reached three kilometers, and the weakest place was one or two kilometers, which could withstand the frontal attack of nuclear bombs.

It includes engine casting workshop, boat hull manufacturing workshop, large deformation equipment manufacturing workshop, and special equipment manufacturing workshop, etc., and there are more than ten large workshops.

Each workshop is divided according to the level.

A total of tens of thousands of people can be accommodated in it, working and resting. The new casting base is operated in three shifts. After each shift is handed over at the entrance, the lead ferroalloy gate as thick as eight meters is slowly closed under the powered motor to prevent emergencies.

There is air filtering, exchange equipment, and connected to groundwater. In addition, a large amount of food and equipment is stored. In critical moments, the cave can ensure that 20,000 people are not harmed by the external environment within one year.

After the factory was moved to the hillside, the temporary factory outside was vacant.

However, it was only vacant for less than half a year, and new personnel arrived again.

This is the aerospace plane testing team led by Mr. Wang.

They retained a factory building near the mountain wall, and other buildings were pushed down and filled. From outside the mountain, high-grade cement was transported and a ten-kilometer-long super-long runway was built.

The test data collection machine is only one tenth of the full size and is about nine meters long.

However, since aerospace planes must ensure ultra-high-sonic flights, they cannot adopt the appearance design of conventional aircraft, and their wingspan will form strong resistance during flight.

To this end, the shape of the aerospace plane adopts a super high-speed aerodynamic, so-called "ascending body", that is, a blunt-head triangle.

This type of aircraft will form an upward support when flying at super high speed, reducing power consumption and saving energy.

It's just because the wingspan is too small, a longer runway is required when conventional turbo drives take off.

Moreover, due to the large size of the aircraft, most of them use new alloy formulas, and the full-size self-weight itself reaches 132 tons. The landing support frame, sliding tires, etc. alone must be specially made. In addition, the belly of the aircraft has also been specially reinforced.

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

The paved runway alone has reached a thickness of 600 mm!

With this item alone, the cost of this runway reached more than 50 million yuan!

The aircraft adopts an operating mode that combines ground remote control flight and accompanying remote control flight, and specially borrows a J-8 from the Air Force for modification. The weapon system was removed and the remote control blue was installed, and the operators were in the back seat and remotely controlled flight.

There is no way to do this either.

The composite engine used by the space shuttle uses a turbine when taking off. When it reaches Mach 4, the rocket engine can be accelerated for a short time to reach Mach 5 or more, and the scramjet engine can only be started.

Once activated, its speed can suddenly increase to more than Mach 10, and radio wave tracking will be extremely hard.

Even if the high-altitude remote control of J-8 is adopted, it can only fly to high altitude in advance and use segmented remote control to ensure that the aircraft will not break away from control.

As for the ceiling, it is not a problem. The practical ceiling of the J-8ii reaches an extremely high altitude of 18 kilometers, and the normal take-off altitude of the aerospace plane can only reach this level. Upwards, you can only use rocket engines to boost it, rush out of the thin air atmosphere, and keep up hundreds of kilometers to reach low-Earth orbit suspension.

The low-Earth orbit is not unattractive, but the center of the earth's suction has reached this height and is already very small.

Aerospace planes can hover in low-Earth orbit for more than half a year, and only require a little thrust of the rocket engine to maneuver at ultra-high speed. During this period, it will drop altitude bit by bit under gravity until it falls into the atmosphere.

At this time, the space plane can use its own turbine engine to slow down its speed and fly back to the airport by itself.

In fact, in terms of African bases, various indicators of aerospace planes have been tested in a simulated environment, and tens of thousands of improved designs have been made successively.

This is an advantage that no other country or scientific research organization cannot match. In a nearly real physical environment, design loopholes that may cause fatal defects are found in advance, improved, or redesigned. In other aircraft research, it takes years or even decades of repeated flight tests to master some key data. In this process, the crash of the test aircraft is common due to design defects. In order to find the cause of the crash, designers had to re-create a verification aircraft with the same defects to find the problem of the accident.

After much trouble, a study was intermittent and stuck in the mastery of some key data for a long time.

While foreign researchers were still having headaches over the high R&D costs and slow research progress, researchers at African bases had already obtained all the arguments in a virtual environment. What they spent was their intelligence and some power consumption.

If it weren't for the fact that human scientific understanding was far from enough, the virtual environment could only be an incomplete simulation, and the African base could be finalized and produced prototypes without actual testing.

Even so, it is also a test machine for early data collection. Except for the prototypes made by Wang Gong and others, only one-tenth of the full design size, from the kernel to technology, and extremely mature, there is no difference from the final qualitative style.

The only difference between this aircraft and live driving is that it adopts remote control.

Inside it, there is also an intelligent auxiliary flight system built by ninety-nine optical brain processor chips.

Although the ninety-nine optical processors, although the combined size of a basketball is less than a basketball, rely on the super computing power of tens of billions of times, form a supercomputer system with a computing speed of billions of times.

Inside the optical brain, it is equipped with a miniature version of the Hongjun intelligent system.

This version focuses on flight control. Most of its data comes from the relevant data of African bases in the simulation system, and some of them come from the data of the Chinese military simulated flight trainer in the Pangu world built by the headquarters of Beijing Huanyu Company.

How a real pilot controls an aircraft, how to deal with special circumstances, how to fight air combat, etc., is a demonstration made by the ace pilot of the Air Force, which is sorted into a data link and provided to Hongjun's intelligent system.

The remote control personnel only need to give a simple command, such as "take off", "land", "circle", "fly upward", etc. The Hongjun intelligent system can make a certain independent response based on the preset program, and test it according to the instructions based on the flight status, control performance, etc. at that time.

At the beginning, the data collector only conducted two tests: takeoff and landing, and adopted full manual remote control.

Afterwards, these data were optimized and merged with the operating software of Hongjun Intelligent System, and then gradually handed over to Hongjun Intelligent System for independent operation.

Wang Gong and his team carried out very carefully. Each project has undergone dozens of tests before the next item was carried out.

Employees and families of the large-scale casting base of Universal Company discovered that this peaceful basin, like a busy airport, heard the sound of supersonic breaking through the air every day, sometimes far and sometimes near, rumbling across the sky.

The intelligence department also intercepted several employees' children, took photos of the aircraft secretly, and tried to send them to the Internet, and immediately gave severe measures.

People endured the noise caused by the harsh breakthrough of the supersonic sound barrier and endured it for two years. Then, as soon as they woke up, they suddenly realized that the sound that disturbed them every day could no longer be heard.

The factories in the valley are still running, and the runway still extends straight.
