Doomsday Bunker Upgrade

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

It’s just that this runway has not been used 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 on a land cruiser, they just landed on the snow-covered tarmac.

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

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

Therefore, in order to solve the runway problem of the aerospace aircraft test flight, the staff of the base spent three days before leveling the snow-covered runway, so that it at least meets the standards of the field airport and can be used for the test flight of the aerospace aircraft.

“Is there a problem with the runway? The plane’s engine ignites and the runway melts directly?” Chen Xin’s worries were not unreasonable guesses. After all, the technical verification aircraft of the aerospace plane used for test flight still uses a traditional jet engine. The NVN induction force field engine and KD-64BV variable cycle engine set on the Xuannv Aerospace Unmanned Fighter in the Nantianmen Project.

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

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

But this also brings about a problem, that is, when the aeroplane engine starts, the temperature of the tail flame can reach thousands of degrees, let alone melt the snow, it will be evaporated in an instant.

The researcher on the side of 　　 didn’t worry too much about this, and replied to Chen Xin: “Academician Chen can rest assured about this. We have made detailed calculations and there will be no problems.”

said, he gave Chen Xin a detailed introduction to the aerospace plane, explaining that even if the snow on the runway is evaporated by the aerospace plane’s tail flame, it will not affect the test flight of the aerospace plane.

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

But he still feels a little worried, so he asks more.

And not only asked, Chen Xin also sent the researcher’s explanation to Xi Yao, and asked her to help with derivation and calculations.

Even though the data was calculated by Xiyao when the project team submitted the application plan for the test flight to Chen Xin before the test flight started, he still asked Xiyao to do the calculation again, after confirming that there was really no problem. , Before agreeing to let the sky plane take off.

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

Chen Xin raised his binoculars and looked at the plane on the runway. At this time, it had been sprayed with a layer of black protective paint, which looked very inconspicuous.

But the fully enclosed nose, which is different from the glass cockpit of the traditional aircraft, still illustrates the nature of this aerial drone.

“I remember Xuannv’s design uses forward-swept wing and manned/unmanned two modes of operation, right?” As the test-flying aeroplane entered the reserved position on the runway, Chen Xin suddenly spoke to the researcher on the side. Asked.

According to the original design of the Nantianmen Project, the Xuannv Aerospace Unmanned Fighter uses nerve-sensing control. 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 neuron computer that is a bionic human brain is installed in the cockpit to control the flight of the aircraft and perform tasks.

Of course, there is no problem with such a design. Except that the current technology can’t do these things at all, it does not have any shortcomings.

Even the wing design of the aircraft was specially made for feasibility analysis at that time. Although it cannot be said that it must be reasonable or superior in performance, at least this structure can really fly.

Therefore, after the entire Nantianmen Project was taken out, the original sci-fi level settings and requirements were simply modified or lowered to make them in line with 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 the test flight had mostly abandoned the original design of the Xuannv Aerospace Unmanned Fighter.

This technical verification aircraft is not so much the actual product of the Xuannv Aerospace Unmanned Fighter, as it is just a redesigned aircraft based on the idea of ​​the Xuannv Aerospace Unmanned Fighter.

The researcher on the side apparently understood this problem, and faced Chen Xin’s question and explained to him: “In addition to our technology’s failure to reach the original design of the Xuannv fighter, there are also certain problems with its layout, such as its The forward-swept wing design and the front wing of the diamond-shaped connecting wing design will have a certain conflict, which will greatly affect the aircraft’s elevation performance. Therefore, we modified the aerodynamic layout and redesigned the aircraft.

At present, the technical verification machine you see, the academician, uses an 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 conducted a wind tunnel test.

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

Hearing what the researcher said, Chen Xin was not surprised. When he went to inspect before, he did not pay much attention to the shape of the aircraft. After all, he had a lot of things at that time, so the specific responsibility for each project was given to the project team. Long go to deal with it all.

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 airplanes. If it weren’t for the conceptual design of the Xuannv Aerospace Unmanned Fighter in the materials in front of him, which looked different from the technical verification aircraft in front of him, he might not have been able to find this. The point is different.

Just as Chen Xin and the researcher were talking about this, the technical 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.
