This is a special stealth material that has a certain ability to absorb waves and absorb light. To put it simply, it absorbs most of the light that hits it, reducing the likelihood of being detected.

Most of the objects that we can see are visible to the eye because they reflect light, not glow.

When the projected light source is absorbed or not reflected, it is difficult for the human eye to see the object.

Of course, it only has a certain ability to absorb light, so the human eye still sees it, and it cannot achieve the optical stealth effect in the full sense.

But in a certain environment, it still has some optical stealth capabilities.

For example, in the low visibility environment at night, this special stealth coating can make this intelligent attack drone and the night sky better integrated, not easy to be detected by the naked eye. In addition, it is not easy to be detected by radar, so the stealth efficiency has been improved a lot.

Multiply......

With a screeching sound, the first intelligent attack drone landed on the runway very smoothly and raised the speed brake.

Because the fighter adopts a super aerodynamic shape, the starting shape of the fuselage is a very smooth streamlined design, so it needs to be assisted by a speed brake to decelerate.

Otherwise, it may cause the drone to rush out of the runway because of the high speed, or because of the long-term high-speed braking, resulting in overheating of the brake pads, tire fire and other accidents.

Now fighters have relevant deceleration devices, and in addition to the deceleration plates, there are actually parachutes, like parachutes, in the tail of the aircraft.

When the fighter plane lands and taxied on the runway at high speed, the parachute is released, which slows down the fighter due to the huge air resistance.

It's just that the parachute needs to be thrown away every time it is used, and then folded and installed again, which is not conducive to the continuous operation of the fighter's second lift-off in a short period of time. Therefore, now the air force fighters of many countries, including our country, have begun to gradually switch to the use of speed brakes.

In addition to this deceleration method, there is actually another one, and that is the engine thrust reverser. It's just that this method is generally used on large aircraft with external engines, and fighters with built-in engines generally do not use this method.

Of course, fighters like some countries will be equipped with two deceleration schemes, which are generally used together with a deceleration plate and a deceleration parachute.

Its purpose is to play the role of double insurance on the one hand, and on the other hand, it is also to deal with take-off and landing in extreme situations.

For example, in some short-distance combat airfields, take-off and landing, the use of these two deceleration methods can allow fighters to stop quickly.

On the other hand, it is also in order to be able to take off and land short distances in wartime, when the runway is emotionally damaged.

At present, their intelligent attack drone is only equipped with a speed brake. As for the parachute, it will be added according to the needs of customers in the later stage.

As the drone slowed down and slowly taxied onto the tarmac, another drone successfully landed on the runway.

Under the guidance of the guide, the drone, which had been switched to the manual remote control mode, slowly glided at the preset position and stopped steadily.

As the engine turned off, the technicians and maintenance personnel who were waiting on the side had stepped forward and began to nervously check it.

Seeing this, the people who were waiting on the tarmac immediately walked towards the drone, which was already quite stable.

Looking at the technicians and maintenance personnel who were inspecting, the crowd did not come forward to disturb, but stood around there.

Suddenly, Luo Kai saw the green color coming out of the wings, and couldn't help but step forward and touch it: "Look, is this a leaf rubbed when flying at an ultra-low altitude." ”

Seeing the green in Luo Kai's hand, everyone couldn't help but nodded. Indeed, when a fighter is flying at an ultra-low altitude, it is likely to hit some objects, leaves and treetops, which is a very common thing.

Of course, for the sake of safety, it is generally not to descend to that limit. Normally, helicopters are more often used because it is the "treetop killer".

The only way this fighter flew at ultra-low altitude was in the mountains and valleys, and it was able to touch the leaves, which is enough to show the extreme degree of flight altitude at that time.

So this naturally caused everyone's amazement, the automatic flight control ability of this drone is indeed very strong, comparable to an ace pilot.

"Okay!" Xiao Yunfei patted the flattened nose of the drone and showed a regretful smile: "This exercise showed us the excellent performance of this intelligent attack drone, which opened our eyes."

However, it is still a pity, that is, I did not see this fighter mounted with live ammunition to hit the target. ”

Everyone nodded when they heard this, which is indeed a pity.

But there is no way, on the one hand, because it is not easy for this Gyeonggi center to approve this drone autonomous flight exercise, let alone let the drone carry live ammunition for autonomous attack.

There are too many uncontrollable factors and too many risks, and no one can afford to have an accident in this regard, so it can only be canceled.

As a private enterprise, it can be said that it is very difficult to obtain live ammunition, and it needs to go through very complicated procedures.

Therefore, the previous tests in the Northwest Research Center were basically mounted training bombs, that is, solid model bombs. Its main purpose is to test the built-in magazine of this intelligent attack drone.

These include the opening and closing of the built-in magazine of the UAV in high-speed flight, as well as the impact of the built-in magazine on the aerodynamic shape of the UAV when it is opened, and even the impact on the stealth performance after the magazine is opened.

In the Northwest Research Center, with the help of the Air Force, they carried out two very successful live-fire target missions.

One was when the intelligent attack drone dropped a domestic air-to-ground missile at an altitude of 5,000 meters, and successfully concentrated the bullseye of the ground target.

The second time was that the drone successfully launched an air-to-air missile at an altitude of 3,000 meters and hit the flying target aircraft in front.

The success of these two live-fire targets means that their intelligent attack drone has very good ground and air attack capabilities.

Originally, Wu Hao and the others also wanted to show it. But the environment doesn't allow it, so this is also a big regret for everyone in this exercise.

Despite the regrets, it did not prevent the success of the demonstration of this exercise. Judging from the reaction of everyone, their intelligent attack drone really conquered everyone on the scene with its excellent performance.

That's why Xiao Yunfei was so interested, and after the exercise, he came to the tarmac again to welcome the drone back and land.
