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 aircraft taking off and landing on this runway for several years.
When Chen Xin and the others arrived on the land cruiser before, they only landed on the snow-covered tarmac.
It's not that they don't clear the snow, but it's really a huge project to clear the snow that's 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 cleared away, the ground will still easily become icy and slippery on such a cold day.
So in order to solve the problem of the runway for the aerospace aircraft test flight, the base staff spent three days leveling the snow-covered runway to make it at least meet the standards of a field airport and can be used for the aerospace aircraft test flight.
"Is there no problem with the runway? If the aircraft engine ignites, the runway will melt directly, right?" Chen Xin's worry is not groundless conjecture. After all, the technology demonstrator of the aerospace aircraft tested still uses a traditional jet engine, not The NVN induction force field engine and the KD-64BV variable cycle engine are installed on the Xuannv aerial drone in the Nantianmen Project.
The so-called nvn induction force field engine is a radiation propulsion engine that uses the products of the cataclysmic reactor as a medium for propulsion. This propulsion method is still too early for humans, and technology has not yet developed to this point.
Therefore, this aerospace plane uses traditional engine technology that is currently mature. Relying on the advanced technology provided by various countries, this aircraft can meet the design requirements.
But this also brings about a problem, that is, when the aerospace aircraft 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 melting.
The researcher on the side was not too worried about this and replied to Chen Xin: "Academician Chen, please rest assured that we have made detailed calculations and there will be no problem."
With that said, he introduced the situation of the aerospace plane to Chen Xin in detail, explaining that even if the snow on the runway is evaporated by the tail flame of the aerospace plane, it will 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, they obviously made detailed calculations in all aspects and decided to do so only after confirming that there was no problem.
But he still felt a little worried, so he asked more questions.
And not only asked, Chen Xin also sent the researcher¡¯s explanation to Xiyao, asking her to help with derivation and calculations.
Although these data were calculated by Xiyao 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, and after confirming that there was really no problem , only then agreed to let the aerospace plane take off.
As Chen Xin¡¯s order was conveyed, the aerospace aircraft on the runway began various pre-flight inspections and started the engine.
Chen Xin held up the telescope and looked at the aircraft on the runway. It had been sprayed with a layer of black protective paint and looked very inconspicuous.
But 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 two operating modes: forward-swept wing and manned and unmanned, right?" Watching the test-flying aerospace aircraft enter its reserved position on the runway, Chen Xin suddenly asked the researcher on the side casually One sentence.
According to the original design of the Nantianmen Project, the Xuannv aerial unmanned combat aircraft uses neural induction control. The pilot directly controls the aircraft through the helmet, so there is no need for the glass cockpit of traditional aircraft.
In unmanned mode, a neuron computer that mimics the human brain will be installed in the cockpit to control the aircraft's flight and perform tasks.
There is certainly nothing wrong with this design. Apart from the fact that current technology simply cannot do these things, there really are no shortcomings.
Even the wing design of the aircraft was specially designed for feasibility analysis at that time. Although it cannot be said that it is necessarily reasonable or has superior performance, at least this structure can really fly.
Therefore, after the entire Nantianmen plan was taken out, the original sci-fi level settings and requirements were simply modified or lowered to make them consistent with reality and the current level of technology. Other than that, there were no further changes. Make more adjustments.
But on the space plane, what Chen Xin saw was this?The technology verification aircraft that was tested abandoned most of the original design of the Xuannv aerial drone.
Rather than saying that this technology verification aircraft is a realistic product of the Xuannv aerial drone, it is better to say that it is just a redesigned aircraft based on the ideas of the Xuannv aerial drone.
The researcher on the side obviously understood this problem, and when faced with Chen Xin's inquiry, he explained to him: "In addition to the fact that our technology is not up to the original design of the Xuannv fighter, there are also certain problems with its own layout, such as its There will be a certain conflict between the forward swept wing design and the diamond-shaped wing design, which will greatly affect the aircraft's elevation performance. Therefore, we modified the aerodynamic layout and redesigned the aircraft.
At present, academician, the technology verification aircraft you see uses an aerodynamic shape originally 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. , only wind tunnel testing was conducted.
This time the Nantianmen Project had a need in this regard, so Lucia took out this design, coupled with other finished technologies provided by various countries, so we have the current technology verification machine. "
Chen Xin was not surprised when he heard what the researcher said. When he went to inspect before, he really didn't pay much attention to the shape of the aircraft. After all, he had a lot to do at that time, so the specific responsibility for each project was handed over to the project team. The president has full authority to handle it.
He is only responsible for dealing with overall issues, 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 the information in front of him hadn't included a conceptual design drawing of the Xuannv aerial drone, which looked different from the technology demonstrator in front of him, he might not have been able to discover this. A little different.
¡°While researcher Chen Xinhe was saying this, the technology demonstrator aircraft on the runway also completed all preparations before taking off. The engine sprayed out a long tail flame, pushing it into the blue sky.
