The Gobi Desert, the base of the desert.

A H-6H stopped in the take-off position, and a strange thing hung under the belly.

The front half of it is a small delta airfoil with a WCR09 combined power engine mounted on it, as well as fuel tanks and simple control parts.

After the construction of the first WCR09 combined power engine was completed, at the strong request of the military, Xinyuan did not test the flight itself, but moved to the desert base, and the researchers here designed a small airframe for the test flight.

The triangular vehicle, codenamed W-1, is a pure demonstrator to test whether the WCR09 is up to standard.

In order to simplify the design and even have only a disposable landing gear, which cannot be used for take-off, two skids are stretched out to land when landing, and they can be replaced after grinding.

After all, it is a vehicle that verifies flying 10 times the speed of sound, and it is very troublesome to dig out a serious landing gear, so simply don't do it yet.

At this time, it was already January, but it was not time for the desert base to take a vacation, and Lin Ju stood in the warm control room, where the monitoring data of W-1 from various aspects was summarized.

As the test command was issued, the H-6H taxied and took off, flying all the way to an altitude of 12,000 meters above the central position in the northwest desert, the operator pressed the button, and the explosive bolt on the pylons that fixed the W-1 was disconnected and the W-1 was thrown down.

The turbofan part of the WCR09 was immediately activated, and the thrust of 9 tons was too much for the W-5, which weighed less than 1 tons, and the speed exceeded Mach 2 in a few minutes after turning on the afterburner, and it was still rising.

At the same time, the height of the W-1 continues to rise, reaching a height of 30,000 meters at Mach 2.8, and there is still power left, and it is still climbing.

Finally, when the turbofan section reached its limit, the W-1 had already reached an altitude of 43,000 meters and a speed of Mach 3.13!

For the first time, the desert base felt the advanced technology of WCR09, that is, the turbofan is not a turbojet, and it can work normally at an altitude of 40,000 meters.

Although the thrust is a little smaller, this high-altitude and high-speed performance is indeed born for the sky.

Immediately after that, the ramjet engine section showed that the starting conditions had been reached, and the ground immediately commanded to enter hypersonic mode.

In the air intake of the WCR09, the movable partition that originally closed the ram part was slowly folded downward, and the turbofan engine began to reduce its thrust, and the thinner air of the ramjet engine poured into the air intake at high speed, which slowed down through the flared air intake, but the air flow still exceeded the speed of sound.

In the combustion chamber, the atomized composite fuel is ejected and then ignited.

With a detonation, the scramjet engine ignited successfully!

The air intake of the turbofan engine is completely closed, and the thrust is supplied entirely by the ramjet engine.

The ground did not accelerate a little due to the direct increase in engine power, because the W-1 did not have so much fuel.

From Mach 3.2 to Mach 6, the WCR09 was propelled by a scramjet engine in just 40 seconds!

The speed of the air flow is getting higher and higher, but the violent air flow becomes controllable after a simple but extremely precisely designed air intake, and finally enters the combustion chamber and ignites the fuel to burst out thrust.

The ramjet engine is actually very simple, an air duct, a fuel nozzle inserted in the middle, an igniter, and it's over.

The airflow enters, the fuel is injected, the ignition is ignited, the thrust is generated, it's as simple as that.

The traditional jet engine must first decelerate the airflow to subsonic speed through the air intake, and then decelerate through the compressor blades, so that the air pressure and airflow in the combustion chamber can be stabilized, and the ignition is to generate thrust.

The difference is only in the design of the air intake of this pipe, the design of the combustion chamber, as long as you change the angle of the air intake, you can create a variety of types such as rotary detonation ramjet engine, sub-combustion ramjet engine, etc., magical, right?

But it's such a simple design, but it represents a supercomputer's day-and-night simulation of fluid dynamics, and any small change in hypersonic airflow can have a huge impact on engine conditions.

And, of course, there is the loud noise of the ramjet engine when it works.

In the western Xinjiang and Mongolia, people heard a loud rumbling sound from the sky, which was the sound of the W-1 breaking through the 8 times the speed of sound barrier and generating a strong shock wave transmitted to the ground.

In time, it was more than 40,000 meters in the air, and people on the ground could also feel their ears buzzing.

People looked up curiously for a long time, and finally an orange-white bright spot appeared, dragging a long white trail to draw a curved line in the sky, and finally the trail spread out to form a spiral.

At the desert base, Dou Ping slapped himself in the face:

"It must be the insulation failure, the W-1 is finished!"

Researchers on the ground rushed out of the control room and saw W-1 that had gone out of control and turned into a meteor.

It will eventually fall somewhere in the desert at super high speed, becoming a large piece of wreckage.

Guo Shen helped his glasses:

"It should be that the gap of the skid is not well handled and overheated, it is normal for the design of the W-1 to be in a hurry, and what is the flight speed in the last normal state?"

"I'll see...... 47,700 meters, speed... Mach 10.6! I'll go! ”

Dou Ping looked at the data obtained at the end and shouted in surprise.

Without rockets, scramjet engines flew above Mach 10!

Other researchers were also shocked, although the indicators of WCR09 were high, but no one expected that the first flight would be so fierce, this is the real vigorous flying brick!

Guo Shen was expected:

"Then the Snow Bird can enter the formal design, since the airframe design is your responsibility, then let's take the air intake, I also have some ideas for the aerospace plane now, maybe we can integrate the rocket part into it."

Dou Ping shook his head: "You Xinyuan are really radical and excessive, we plan to use a triangular body for the body of the Snow Bird, and the four engines are placed on the abdomen, how about it?" ”

"It's your business, as long as WCR09 tests well, my task is basically done, right? The W-1 uses the paint of the missile warhead, and the Snow Bird cannot afford to use this. ”

"I don't have a clue."

Dou Ping is very single, because the adjacent space vehicle is also an atmospheric vehicle, and it is too troublesome and expensive to paste the heat insulation tile like the space shuttle, so he still has to take the traditional skin route.

At present, the material selection preparation of the base is selected in titanium alloy and high-grade stainless steel, but titanium alloy Lucia is a big country in production and resources, and there are not many countries in China, and the difficulty of high-grade stainless steel is not more difficult than that of titanium alloy.

Guo Shen didn't speak, but he had a clue.

The H2 space shuttle is ready to abandon the route of attaching heat insulation tiles and integrate the heat insulation tiles with the fuselage to meet the life of at least 100 take-offs and landings, and Xinyuan is still working hard to develop it.

Such a new integrated skin design can also be used in aerospace aircraft, and it is difficult to say whether the desert base will be completed at that time.

A few days later, news of UFOs and meteors appearing in the western region appeared in many places, and the spokesman said that the official knew nothing about them, but Aramco believed that it was a missile test.
