Doomsday Bunker Upgrade Chapter 743: Aircraft test flight

The military base used as the research site for the Nantianmen Project is an air force base and naturally 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 by land-based ship, they just landed on a 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 a very huge project to clear, and the snow is frozen very thick. Instead of cleaning the snow, it is better to open a road roller Snow compaction is used directly on the ground.

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

So in order to solve the problem of the runway for the test flight of the aerospace plane, the staff of the base spent three days before leveling the snow-covered runway so that it can at least meet the standard of a field airport and can be used for aerospace planes test flight.

"Is there any problem with the runway? Wouldn't the plane's engine be ignited and the runway would melt directly?" Chen Xin's worry is not groundless speculation, after all, the technical verification machine of this aerospace plane is still using traditional jet engines. , not the NVN induction force field engine and KD-64BV variable cycle engine set on the Xuannv aerial unmanned fighter in the Nantianmen plan.

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

Therefore, this aerospace plane uses the traditional engine technology that has matured at present. With the advanced technology provided by various countries, the plane can meet the design requirements.

However, this also brings a problem, that is, when the engine of the aerospace plane starts, 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 researcher on the side was not too worried about this, and replied to Chen Xin: "Academician Chen, please rest assured, we have made detailed calculations, and there will be no problem."

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 tail flame of the aerospace plane, it would 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 made detailed calculations in all aspects and decided to do so after confirming that there was no problem.

But he was still a little worried, so he asked a lot more.

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

Although he had asked Xiyao to calculate these data before the test flight started, when the project team submitted the test flight application plan to Chen Xin, he still asked Xiyao to calculate it again, to be sure that it was true. After there was no problem, it was agreed to let the aerospace plane take off.

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

Chen Xin held up the telescope 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 unlike the fully enclosed nose of the traditional glass cockpit, it still illustrates the essence of this aerospace aircraft drone.

"I remember Xuannv's design is to use forward swept wings and manned/unmanned operation modes, right?" Watching the test-flying aerospace plane enter the reserved position on the runway, Chen Xin suddenly turned to the man beside him. The researcher asked casually.

According to the original design of the Nantianmen Plan, the Xuannv aerial drone uses neural induction control. The pilot directly controls the aircraft through a helmet, so the glass cockpit of a traditional aircraft is not required.

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

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

Even the wing design of the aircraft was specially analyzed for feasibility at that time. Although it cannot be said to 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 conform to reality and the current technological level. No further adjustments were made.

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

Rather than saying that this technical verification machine is the product of the reality of the Xuannv aerial unmanned fighter, it is better to say that it is just a redesigned aircraft according to the idea of ​​the Xuannv aerial unmanned fighter.

The researcher on the side obviously understood this problem, and in the face of Chen Xin's question, he explained to him: "The original design of the Xuannv fighter jet is not up to our technology, and there are certain problems in its own layout. For example, its forward swept wing design and the diamond-shaped wing design of the front wing will have a certain conflict, which will greatly affect the elevation performance of the aircraft~IndoMTL.com~ So we modified the aerodynamic layout and redesigned the aircraft.

At present, the technical verification machine you have seen, academician, uses an aerodynamic shape originally designed by Lucia for the Su-47 Golden Eagle, but the entire Su-47 project has not been put into production, so this design is not It was actually produced, but only tested in the wind tunnel.

This time the Nantianmen project had this need. Lucia took this design out and added other finished technologies provided by various countries, so the current technology verification machine was created. "

Hearing what the researcher said, Chen Xin was not surprised. When he went to inspect 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 leader has full authority to handle it.

He is only responsible for the big picture, so specific details like this can only be seen when the plane is flying.

Especially Chen Xin doesn't know much about aircraft. If it weren't for the fact that the document in front of him contained a conceptual design drawing of the Xuannv aerial drone, which looked different from the technical verification aircraft in front of him, he might not have can see the difference.

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