After checking the list of all the current buildings of the base, Fan Yize left the console, took the elevator of the base console, and went all the way down to the seventy-first space of the base.

This space is a dedicated integrated flight experiment space.

In this space, there is one of the most complete wind tunnel laboratories on the base.

In the control room of the space, Fan Yize saw that in one of the super-large wind tunnel laboratories, there was a very elegant and beautiful aircraft, which was being tested in the wind tunnel.

The craft is made of the same exterior material as the ladder, which is stronger than the base's most advanced depleted uranium armor, and is highly flexible and stretchable.

As we all know, when an aircraft enters supersonic speed, the fuselage will be stretched because of the speed, and the degree of stretching is different depending on the speed.

Therefore, the material of the aircraft fuselage, especially the fuselage structure of supersonic aircraft, must have the characteristics to withstand tensiling.

The tensile property of the ladder can easily meet the tensile of more than 20 times the speed of sound, and the material itself has an excellent guiding effect on air resistance, which is also the main successful feature of the ladder from the ground surface to space.

The channeling of air resistance can make the aircraft made of this material have the same high-speed flight performance as the high altitude in a high-density and low-altitude environment.

Supersonic aircraft are in high altitudes, and because the air is thin and the air resistance is reduced, it is easier to enter supersonic speeds.

However, in ultra-low-altitude environments, it is particularly difficult to enter supersonic speeds.

It's like the Tejas fighter developed by India is itself a third-generation aircraft, and the third-generation aircraft is a necessary skill for supersonic progress, and it can also enter supersonic speed at ultra-low altitudes.

However, when the Tejas fighter gradually matured in the test aircraft, it was indeed possible to enter supersonic speed at high altitude, but at the beginning, at ultra-low altitude, there was no way to enter supersonic speed.

Because the air density at low altitude is higher and the flight resistance is high, if you want to enter supersonic speed, you need more powerful thrust to allow fighter jets to break through the speed of sound at low altitudes.

After the use of this new material, even a fighter with average thrust can barely enter supersonic speed at high altitude, and an aircraft flying to Mach 1.2 can easily enter supersonic speed at ultra-low altitude, and can easily fly to Mach 1.5 at high altitude.

The lighter fuselage also brings better flexibility, further strengthening the fuselage structure, which can allow the aircraft to make more difficult flight maneuvers.

At this moment, this test aircraft in the wind tunnel is the fifth-generation fighter that will be equipped with the Red Guard Corps.

The fighter in the wind tunnel is a twin-engine single-seat stealth heavy air superiority fighter, the fuselage adopts the characteristics of the whole machine integrated structure, so that the aircraft does not need a rivet, and there is no welding and stitching area, from the engine to the fuselage, like a complete whole, but the key parts inside the engine can be replaced at any time, and will not affect the service life of the aircraft because of the life of the engine.

It can be clearly seen from the aircraft test data in front of Fan Yize that the size of the fuselage of this machine is completely the weight of the fuselage of a heavy fighter, and the entire aircraft is not even ten tons.

Although there was not a drop of fuel in the conformal fuel tanks used, and there were no weapons in the four concealment magazines, all the other equipment of the aircraft had been installed.

This is an aircraft that can be used by pilots at any time as long as it is refueled with fuel and ammunition.

Compared with the world's fifth-generation aircraft, the general empty weight is more than 20 tons, and the weight of this fifth-generation aircraft is only half of the empty weight of other fifth-generation aircraft.

This means that the aircraft itself can carry more fuel and carry more weapons and ammunition.

In fact, the plane, which is undergoing final testing in the wind tunnel, is capable of carrying more than 15 tons of aviation fuel and 12 tons of ammunition at a time, and if necessary, the total combat weight can reach more than 42 tons, and it can be equipped with five tons of external ammunition or auxiliary fuel tanks.

In addition, the fuel consumption rate is 60 percent that of other fifth-generation aircraft, and the flight speed is 60 percent higher than that of fifth-generation aircraft of the same level.

This is quite an astonishing combat distance, and at the same time quite a terrible combat efficiency.

Similar fifth-generation aircraft, among the service models planned by the Red Police Corps, there are three different fifth-generation aircraft.

The first is the Intruder fifth-generation aircraft, which has a total flight weight of about 30 tons, and is specially designed for the vertical short take-off model used by the amphibious fleet, the close-range ground-to-air support model for rapid deployment on the front line, and the complex mountain and jungle support model.

The fifth-generation Black Hawk fighter will be used as the main model of the navy and air force in air supremacy, specially used to seize air supremacy, and can also undertake the task of ground-to-sea strikes.

As for the third fifth-generation aircraft, it is the latest Apollo fighter, unlike the Invader and Black Hawk fighters, the model improvement has reached the limit, the new Apollo fighter will be a main combat aircraft starting from the fifth-generation aircraft and ready to enter the sixth generation combat power.

At present, the front-line combat units of the Red Guard Corps are already preparing for a comprehensive replacement of combat aircraft, and the replacement of all third-generation aircraft will also be fully transferred to two time and space as training aircraft for reserve forces.

Once the fifth-generation aircraft matures, all front-line combat units and World War II combat units will be fully equipped with fifth-generation aircraft, and all combat aircraft below the fifth-generation aircraft will be eliminated.

This is absolutely incomparable with various countries in modern time and space, because the cost of using fifth-generation aircraft is really not low for all countries, and no country can replace all aircraft with fifth-generation aircraft.

Therefore, fifth-generation aircraft will also be used as a strategic means, rather than being generally sent to the battlefield like a large number of third-generation aircraft.

However, the Red Police Corps is different, because the production cost of the fifth-generation aircraft is not much higher than that of the third-generation aircraft, and the logistics maintenance is also similar to that of the third-generation aircraft, so once the technology of the fifth-generation aircraft matures, the third-generation aircraft will also face the fate of being eliminated in the front-line troops.

So Fan Yize is not distressed at all, like the intruder of the fifth-generation aircraft and the Black Eagle, in the Red Police Corps, it will also be used as an ordinary fighter.
