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

Moreover, due to the large size of the aircraft and the use of a new alloy formula, the full-size demonstrator weighed one hundred and twenty tons.

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

In addition, a special reinforced design has been made in the belly area of ​​the fuselage.

This kind of aircraft has no way to take off and land on conventional runways. It can only take off and land on specially-made super-high-grade runways.

The paved runway alone is 1.5 meters thick!

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

This approximately ten-meter model aircraft adopts an operation mode that combines ground remote control flight and artificial intelligence driving.

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

There is no way around this.

The composite engine used by the aerospace aircraft uses a turbine when taking off. When it reaches Mach 4, it uses a rocket engine to accelerate for a short period of time. When it reaches a speed of Mach 7 or above, the scramjet engine can start.

Once started, his speed can suddenly increase to more than ten, or even Mach 20 or 30.

Radio tracking will be extremely difficult.

Even if the J-10 comes with high-altitude remote control, it can only fly to high altitude in advance and use segmented remote control to ensure that the aircraft will not lose control.

As for the ceiling, it's not a problem. The J-10's maximum ceiling reaches an ultra-high altitude of 18 kilometers.

The normal takeoff altitude of an aerospace aircraft is this altitude.

Going up further, you can only use rocket engines to boost you to break out of the thin atmosphere.

Afterwards, it goes up hundreds of kilometers and floats in low-Earth orbit. It then undergoes orbit correction and maneuvering to increase its speed relative to the blue star, so that it can truly escape the planet's gravity and enter outer space and cosmic space.

Just talking about it casually, the technology involved is already very complicated.

In fact, at the African base, researchers have tested various indicators of the aerospace aircraft in simulated environments 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 physical environment, design loopholes that may cause fatal flaws are found in advance, and then improved or redesigned.

During 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.

This chapter is not over yet, please click on the next page to continue reading! During this process, it is not uncommon for test machines to crash due to design flaws.

In order to find the cause of the crash, the designers had to re-create a verification machine with the same defect to find the problem that caused the accident.

It’s no surprise that after a long period of tossing and turning, a research was carried out intermittently and stuck on some key data for a long time.

While foreign researchers are still troubled by the high experimental costs and slow research progress, researchers at the African base have already obtained all the proofs in the virtual environment.

All they spent was 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 100% perfect simulation, the African base would not need to conduct actual testing at all to finalize and produce prototypes.

Even so, it is still a test machine used for initial data collection.

Apart from the fact that the model machine manufactured by Zhao Gong and the others is only one-tenth of the full size, from the core to the technology, it is extremely mature, and there is not much difference from the final model of the real machine.

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

Inside it, there are three photon processor chips, which form an intelligent auxiliary flight system.

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

The remote control operator only needs to give a simple command, such as taking off, landing, circling, flying upward, etc., and the intelligent system will make certain autonomous responses according to the preset program.

According to the flight status and control performance of the aircraft at that time, the instructions are executed.

Gong Zhao and the others were very careful, and each project was tested dozens or hundreds of times before moving on to the next one.

Families of employees at Infinite Company's large foundry base in the southwest discovered that the formerly peaceful valley had turned into a busy airport.

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

In those years, the intelligence agency also intercepted several employees' children secretly taking photos of aircraft and trying to post them on the Internet. They were immediately dealt with very severely.

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

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

The factories in the valley are still there and the runways are still straight and straight.

However, those people in dark blue uniforms who laughed and danced around a model airplane like children every day were missing.
