Military Technology

"So this smart attack UAV is equipped with a high-speed obstacle avoidance system, which can detect obstacles around the UAV in real time and adjust the UAV's flight attitude in real time under high-speed flight conditions.

In fact, this technology is not new. It has been used in our "Battlefield Sweeper" small high-speed attack drone before.

However, we have improved on this technology in our use of this smart attack drone. Its detection distance, response speed, and detection accuracy have been greatly improved to adapt to faster flight speeds and larger drone fuselages. "

Although Wu Hao just gave a brief introduction, but everyone is a professional and practitioner, how can they not know the importance and advanced nature of this technology.

How to achieve accurate and fast obstacle avoidance under high-speed conditions is also a cutting-edge technology field that major technology giants around the world are competing to study.

This technology has very important applications in many fields. For example, it is widely used in the most popular secondary autonomous driving.

Its main function is to assist the car to drive automatically on the one hand, and on the other hand, it can brake in an emergency when encountering an obstacle suddenly, that is, the anti-collision function.

In addition to automobiles, high-speed trains such as high-speed railways are also widely used. Like the automatic driving technology of cars, one of the development directions of high-speed trains is also driverless.

Moreover, the more important role of this technology is to prevent the high-speed train from suddenly decelerating and braking when it is running without obstacles.

You know, no matter what kind of transportation, the faster the speed, the longer the braking distance.

A car with a speed of 80 kilometers per hour needs a distance of 20 to 25 meters to brake completely. If it is shorter than this distance, it will directly hit the obstacle.

For a car with a speed of 100 kilometers per hour, it needs about 40 to 45 meters to stop completely. A car with a speed of 120 kilometers per hour needs a distance of about 100 meters to 120 meters if it wants to brake completely.

As for the emergency braking distance of high-speed trains, the speed of the train is faster, and its mass is very heavy, so it is very difficult to completely brake it. According to my country's current "Railway Technical Management Regulations" "the emergency braking distance of a train on any railway ramp is specified as 800 meters".

And this standard is still limited, it must not exceed 120 kilometers, that is to say, if it exceeds this speed limit, then the braking distance is far more than that.

In addition to trains, there are also ships. Although the speed of ships is very slow, it is far inferior to cars and trains. However, the tonnage of the ships is too heavy, and they are often tens of thousands of tons, or even hundreds of thousands of tons. It is very difficult to make it brake suddenly.

Because of the nature of water, ships have poor braking capabilities. Therefore, we often see a lot of accidents where ships collide, and the reason is that the distance is too close and it is too late to brake.

Similarly, there are airplanes, especially the drone market that has been relatively active in recent years, and this technology is also being studied.

But the speed of the plane is too fast, and the braking ability is even worse. It can be said that there is almost no way. The only way is to turn to avoid. Therefore, there are still great limitations to the application of this technology on aircraft, especially in terms of high-speed and ultra-long-distance detection.

Before,

Wu Hao and the others successfully used this technology on the "Battlefield Sweeper" small high-speed attack drone.

Subsequently, this technology was also widely used in Wu Hao's drones, as well as some car autonomous driving and collision avoidance technologies on the market.

This time, Wu Hao and the others took out this technology again, and successfully applied it to their smart attack drone, and demonstrated amazing, no, it should be said to be suffocating excellent performance.

The low-altitude and high-speed crossing of the canyon being displayed is enough to prove the uniqueness of this technology. In the canyon with the narrowest distance of 30 meters and multiple sharp bends less than 110 degrees, the two intelligent attack drones swam over very nimbly and lightly like fish swimming in the water.

While everyone was concentrating on the big screen, Tao Guangcheng suddenly raised a question and successfully attracted everyone's attention.

"Can this high-speed obstacle avoidance technology be applied to our fighter jets?"

As a division commander, what he always considers is how to improve the combat effectiveness of his troops. From this technology, he saw related possibilities.

This ultra-low-altitude and high-speed obstacle-crossing flight is indeed dangerous, and even many veteran pilots dare not try it lightly. But if this technology is applied to fighters, it means that all fighters have this excellent high-speed obstacle avoidance capability. In that case, the combat effectiveness of current fighters will be greatly improved.

Facing this question, and everyone's fiery gazes, Wu Hao shook his head with a smile.

"This technology is used in conjunction with the autonomous flight control technology of our drones. If only a single technology is applied to fighter jets, it will not bring much help to pilots.

To put it bluntly, the test of a manned fighter jet flying this kind of canyon route is the pilot's quick response ability and precise control ability. Obviously, this technology does not have the ability in this regard. "

"Then what if this autonomous flight control technology is also installed on fighter jets?" Xiao Yunfei was the one who asked the question this time, obviously he also took a fancy to the broad application prospects of this technology.

Wu Hao glanced at him when he heard this, but still shook his head and said: "It's still very difficult. First of all, the manned aircraft has its own flight control system. So if you want to install this autonomous flight control system, you need to understand these two System reformation and integration.

Even if they are not integrated, the two systems must cooperate with each other without affecting each other.

Secondly, when flying over such a dangerous canyon route, it is necessary to switch to the autonomous flight mode of the fighter, so that the performance of this high-speed obstacle avoidance system can be fully utilized.

At this time, the pilot needs to completely trust the fighter and this system, and must not interfere with the autonomous flight of the fighter.

Often at this time, the pilot will be under super psychological pressure, making it difficult for the pilot to fully trust, and will unconsciously affect or control the aircraft. "

"You're right, this habit is indeed difficult to correct. But this system can indeed greatly improve the combat effectiveness of fighters, and it must be worth paying attention to." Xiao Yunfei nodded and said.

Hearing Xiao Yunfei's words, Li Weihua on the side immediately responded: "Yes, we will organize relevant technical experts to conduct research on the possibility of using this technology and this system on fighter planes, and submit a feasibility report as soon as possible."
