Doomsday Bunker Upgrade

The military base used as the research site for the Nantianmen Project is an air force base, so it naturally has a runway.

It's just that this runway has been unused for a long time. Since the air force base was sealed before the disaster, there have been no planes taking off and landing on this runway for several years.

When Chen Xin and the others arrived in a land ship, they just landed on the snow-covered tarmac.

It’s not that they don’t clear the snow, but it’s a huge project to clear the snow more than ten meters thick, and the snow is frozen very thick. Instead of clearing the snow, it’s better to drive a road roller to compact the snow Use directly on the ground.

The only problem may be that the road surface will become slippery after the snow is compacted, but even if the snow is cleaned up, the ground is easy to freeze and slippery in such a cold day.

Therefore, in order to solve the problem of the runway for aerospace aircraft test flights, the staff at the base spent three days leveling the snow-covered runway so that it at least reached the standard of a field airport and could be used for aerospace aircraft test flights.

"Is there no problem with the runway? Wouldn't the plane's engine ignite and the runway would melt?" Chen Xin's worry was not groundless guesswork. After all, the technology demonstrator of the aerospace plane used in the test flight still used a traditional jet engine. The NVN induction force field engine and KD-64BV variable cycle engine set on the Xuannv Aerospace UAV in the Nantianmen Project.

The so-called NVN induction force field engine is a radiation propulsion engine, which uses the product of the catastrophic reactor as the medium for propulsion. This kind of propulsion method is still too early for human beings, and technology has not yet developed to this point.

Therefore, this aerospace aircraft still uses the mature traditional engine technology, relying on the advanced technology provided by various countries, so that this aircraft can meet the design requirements.

However, this also brings about a problem, that is, when the aerospace plane engine is started, the temperature of the tail flame can reach a high temperature of thousands of degrees, and the snow will be evaporated in an instant, let alone melted.

The researchers at the side were not too worried about this, and replied to Chen Xin: "Please rest assured, Academician Chen, we have made detailed calculations, and there will be no problems."

After speaking, he introduced the situation of the aerospace plane to Chen Xin in detail, explaining that even if the snow on the runway was evaporated by the plume of the aerospace plane, it would not affect the test flight of the aerospace plane.

Chen Xin nodded after listening to the explanation. He also knew that since these researchers were able to formulate such a test flight plan, it was obvious that they had done detailed calculations in all aspects and decided to do so after confirming that there was no problem.

But he was still a little uneasy, so he asked a lot.

Not only did he ask, Chen Xin also sent the researcher's explanation to Xiyao, asking her to help with the derivation and calculation.

Although these data had already been calculated by Xiyao when the project team submitted the flight test application plan to Chen Xin before the test flight started, he still asked Xiyao to do the calculation again worriedly, after confirming that there was really no problem , before agreeing to let the aerospace plane take off.

Following the transmission of Chen Xin's order, the aerospace plane on the runway began various pre-flight inspections and started the engine.

Chen Xin held up the binoculars and looked at the plane on the runway. It had already been sprayed with a layer of black protective paint, and it looked very inconspicuous.

However, the fully enclosed nose, which is different from the glass cockpit of traditional aircraft, still illustrates the essence of this aerospace aircraft drone.

"I remember that Xuannv's design uses forward-swept wings and manned/unmanned operation modes?" Watching the test flight aircraft enter the reserved position on the runway, Chen Xin suddenly said casually to the researcher at the side. asked a question.

According to the original design of the Nantianmen Project, the Xuannv Aerospace unmanned fighter aircraft adopts nerve-sensing control, and the pilot directly controls the aircraft through the helmet, so there is no need for the glass cockpit of a traditional aircraft.

In the unmanned mode, a bionic human brain neuron computer will be installed in the cockpit to control the flight of the aircraft and perform tasks.

Of course, there is nothing wrong with such a design, except that the current technology can't do these things at all, and there are really no shortcomings.

Even the design of the aircraft's wings was specially analyzed for feasibility at that time. Although it cannot be said that it is absolutely reasonable or superior in performance, at least this structure can really fly.

Therefore, after the entire Nantianmen project was brought out, the original sci-fi level settings and requirements only made some simple modifications or lowered the standards to make them conform to reality and the current level of technology. Make more adjustments.

But on the aerospace plane, what Chen Xin saw was that the technical verification aircraft for test flight had mostly abandoned the original design of the Xuannv Aerospace Unmanned Fighter.

Rather than saying that this technical verification aircraft is the product of the actualization of the Xuannv Sky Unmanned Fighter, it is better to say that it is just an aircraft redesigned according to the idea of ​​the Xuannv Sky Unmanned Fighter.

The researcher on the side obviously understood this problem, and explained to Chen Xin's inquiry: "The original design of the Xuannv fighter plane has certain problems in its layout besides our technical failure. For example, its The front wing of the forward-swept wing design and the diamond-shaped wing design will have certain conflicts, which will greatly affect the aircraft's elevation angle performance, so we have modified the aerodynamic layout and redesigned the aircraft.

At present, academician, the technical verification machine you see is the aerodynamic shape designed by Lucia for the Su-47 Golden Eagle. However, the entire Su-47 project has not been put into production, so this design has not been actually produced. , just a wind tunnel test.

This time, the Nantianmen Project needed this, and Lucia took out this design, coupled with other finished technologies provided by various countries, so there is the current technology verification machine. "

Hearing what the researcher said, Chen Xin was not surprised. When he went to inspect the plane before, he really didn't pay much attention to the shape of the plane. After all, he had a lot of things at that time, so the specific responsibility of each project was handed over to the project team. Long go to the full discretion to deal with.

He is only responsible for dealing with the overall situation, so specific details like this can only be seen when the plane is flying.

In particular, Chen Xin didn't know much about aircraft. If it wasn't for the conceptual design drawing of the Xuannv Aerospace Unmanned Fighter in the document in front of him, which looked different from the technical demonstration aircraft in front of him, he might not have been able to discover this. something different.

While Chen Xin and the researcher were talking about this, the technology demonstrator on the runway also completed all the preparations before takeoff, and the engine sprayed out a long tail flame, pushing it into the blue sky.
