Rebirth Technology Power

Chapter 171 Prototype
For any major project in the past, the first thing to start is project approval.

It often takes several years to establish a project.

Then, there is the program demonstration, and this process often takes several years.

The next step is to build a prototype or two.

The prototype flew for the first time, and after almost a year or two of testing, construction of the experimental aircraft began.

The experimental aircraft has undergone a series of tests and improvements, and finally the key design review work has been fully completed, and then the detailed design stage has been completed, followed by finalization and naming.

This process, even if it goes on for ten or 15 years, is quite normal.

Before and after, it is normal for an aircraft to be in service for 30 years!

But now, Cai Jin has actually figured it out.

This kind of thing, no matter how you think about it, seems like something out of the Arabian Nights.

"Mr. Cai Jin, you are an expert in artificial intelligence and other fields, but you have never developed an airplane, so you don't know much about it." The old man couldn't help but said.

He participated in the development of J-[-] and J-[-].

The old man is very aware of the difficulty of developing an advanced aircraft.

Even though China is far better than before, it still faces great difficulties in developing a new generation of aircraft.

The J-[-], according to the current unified standards, belongs to the fifth-generation fighter.

According to the principle of China's weapons development, one generation will be served, one generation will be developed, one generation will be pre-researched, and one generation will be explored.

China is now developing sixth-generation fighters, pre-researching seventh-generation fighters, and exploring eighth-generation fighters!
As an expert in the field of aviation, the old man actually knows that it was Cai Jin who came up with the plan to transform those retired old aircraft into drones. Now it has been proved that Cai Jin is also an expert in the field of drones.

But this is a new aircraft, completely different.

That kind of old-fashioned aircraft is transformed into a drone without changing the aerodynamic layout.

But for a new type of aircraft, the layout needs to be restarted to explore the best aerodynamic layout.

"Actually, I already have a manufactured prototype, which is currently on the suborbital plane and has been tested for ten days." Cai Jindan said with a smile.

Facts speak louder than words.

No matter how much it is said, it is better to see the real thing directly.

The leader who presided over the meeting said: "Comrade Cai Jin, can this prototype land at the designated place?"

"No problem, it's no problem to come directly to this open space." Cai Jin said.

Of course, it is impossible to come here directly.

Safety issues cannot be ignored.

Afterwards, Cai Jin sent the aerospace fighter to the target airport.

It takes a long time to go to the current suborbit, but it is quite easy to return from the suborbit and fly to the target airport.

When Cai Jin and the others arrived at the target airport, the aerospace fighter performed a vertical landing in front of everyone, and landed firmly on the apron.

Each expert showed a look of horror.

This kind of vertical take-off and landing is actually nothing new.

As early as the late 50s, since the birth of vertical take-off and landing technology, this technology has been one of the development technologies that have attracted much attention in the aviation field.

And it is also applied to fighter jets, such as British Harrier aircraft, Russian Yak-36, Yak-141, and the famous F-35 "Lightning" fighter now!

In this regard, China is still in its infancy!

The aircraft using vertical take-off and landing technology is flexible and has incomparable advantages compared to conventional aircraft, but it also has disadvantages. First, the flight range is short, and the take-off weight of the aircraft can only be 83%~85% of the engine thrust, which makes the aircraft's Payload was greatly affected, affecting the aircraft's fuel capacity and range.At the same time, when the aircraft takes off vertically, the engine works at its maximum state, which consumes a lot of fuel and limits the combat radius of the aircraft!
However, this technology is still highly valued. Once this technology matures, it will be even more powerful for naval aviation.

But now, a plane was just in front of them, performing a vertical landing technique.

And at first glance, it is still a mature technology!
The plane then glides into a hangar.

After all, there are too many reconnaissance satellites in the sky.

Confidentiality is still necessary.

Experts in technology began to watch this aerospace fighter carefully.

Unlike traditional fighter jets, this fighter jet obviously has a slimmer fuselage.

There's no cockpit, which means it's a drone!

There is no missile pylon, which means that this drone does not have the ability to launch missiles.

In the previous meeting, they already knew that it only carried one laser cannon.

"Comrade Cai Jin, such an aircraft can really cruise in the suborbit for 20 years?" The leader couldn't believe it.

Just listen to the data, then don't feel anything at all.

If you see it in person, then you will have an intuitive feeling.

Compared with the J-20, this is the younger brother among younger brothers.

"This air and space fighter is unmanned. It uses artificial intelligence or ground command. Once the automatic mode is activated, everything will be dominated by artificial intelligence." Cai Jin explained: "It uses a lot of new technology and new materials. , with a total weight of only two tons, using nuclear batteries, which can continuously provide energy, and all four sets of propellers can rotate 360 ​​degrees.”

"Theoretically speaking, let alone 20 years of continuous cruising, if the material can withstand all kinds of ray corrosion, it will not be a problem to continue cruising for a hundred years."

In space, all kinds of rays can cause damage to materials.

"Nuclear battery!?" An aerospace expert couldn't help but said in shock: "Have you developed mature nuclear battery technology?"

Nuclear battery has the characteristics of small size, light weight and long life, and its energy size and speed are not affected by the temperature, chemical reaction, pressure, electromagnetic field, etc. of the external environment. Therefore, it can be used in a large temperature range and in harsh environments Working in the environment makes nuclear batteries attract much attention in aerospace technology.

But for now, nuclear battery technology is always in the exploratory stage and is not yet a mature technology.

Now China's most advanced nuclear battery technology is applied to the lunar rover, so that the lunar rover can continue to work for 30 years!
But now the difference with Cai Jin's nuclear battery technology is not 01:30.

If there is such a mature nuclear battery technology, then the lifespan of satellites in the future will start at least 20 years, and then in the future, it is estimated that they can still run for 30 to [-] years.

The life of satellites is generally short. Is it because there is not enough fuel and the life of the battery panels is limited, so that once the fuel is exhausted and the life of the battery panels is up, the satellite becomes space junk.

And most importantly, if a deep-space probe is launched and a nuclear battery is installed, the deep-space probe can fly farther and have a longer lifespan.
