Military Technology

Luo Kai shook his head again and again, then looked at Wu Hao very seriously and said: "No, you are not naive, let alone immature. It is just that you have lofty ambitions, and a sense of mission and responsibility for the nation and the country that many people lack.

Your enthusiasm is not in vain. We all see your deeds and your hard work. The leaders and chiefs all see it, and the people of the whole country also see it.

Don't be discouraged, let alone give up. Please believe that there are still many people standing behind you, watching you, and supporting you. "

After the break, everyone sat down again, and the meeting continued.

But this time, everyone seemed to have forgotten the dispute and unhappiness just now, and focused all their attention on this project.

As for Academician Tang Shizhen, he took his own reading glasses, and with the assistance of his assistant, he began to operate the PPT to speak to everyone.

"No matter which control method we choose, it is remote control technology, automatic control technology, or a combination of the two.

All automatic control technologies have a prerequisite, that is, the platform on which they are carried must be sufficiently automated, digitized, and intelligent.

In layman's terms, the targeted aircraft must be sufficiently advanced and have strong dynamic perception capabilities.

Otherwise, no matter how advanced our intelligent unmanned driving system is, we can’t use it on old models like Yun-5 or Yun-7.

The control of these aircraft is entirely based on mechanical power transmission, or even purely mechanical transmission control. It is impossible to modify these aircraft.

Therefore, I think it is very appropriate for Deputy Director Qi to propose using Xinzhou 700 model as our modification experiment platform. "

Speaking of this, Academician Tang Shizhen changed a PPT, which showed a picture of a Xinzhou 700 aircraft in flight.

"Although this Xinzhou 700 regional airliner is advanced enough, and the digital flight control system also meets our requirements, it is not enough for our project, and it lacks the external dynamic perception ability we need.

The so-called dynamic perception ability refers to the ability of the aircraft to obtain external information, which includes the radar on the aircraft and various flight sensors, such as airspeed indicators, altimeters, spirit levels, and barometers.

It even includes some surveillance cameras outside the aircraft, as well as radio receiving devices, which are important components of the dynamic perception system.

The external data information transmitted by these data will assist the pilot to control the aircraft and meet the needs of the pilot to drive the aircraft.

But this is not enough for our intelligent driverless system.

First of all, the system is not a human being, and there are no sensory organs in humans, such as vision, touch, hearing, and smell. The most important of them should be rapid vision and hearing.

The system needs to accept these data through various devices.

In fact, in the process of flying in the air, most of them rely on radar to observe the situation ahead, and rarely use vision directly. Vision is generally used for takeoff and landing, and some emergency situations.

Of course, what I am talking about here are civil aviation passenger planes and transport planes, not fighter jets.

This is not to say that vision is not important, in fact it is very important, especially when dealing with some emergency situations, as well as when taking off and landing, which requires the pilot to have sharp visual observation ability.

The same is true for the system, which also needs to have super visual ability. "

"In this regard, we have widely used synthetic aperture mirror radar and photoelectric pods on drones. The technology in this area is very mature, and we can completely install them directly on the aircraft." Director Song of the test flight center interjected.

Academician Tang Shizhen put down the teacup in his hand, then nodded and said: "Yes, but not enough. This kind of photoelectric pod can meet the needs of ordinary small drones or aircraft, but it cannot meet the needs of medium and large aircraft. For example, medium and large aircraft Its huge body can block the large field of view of this type of photoelectric pod, resulting in incomplete observation.

No matter how advanced the photoelectric observation equipment is, they are still different from what our real human eyes see.

Therefore, if you want to realize automatic control or remote control, the visual field problem must be solved first.

Regarding this aspect, we have specially set up a photoelectric observation system research group, and they have put forward a preliminary design scheme.

That is, multiple photoelectric observation devices are installed at different positions on the entire aircraft to facilitate the system and our remote-controlled pilots to better control dynamic data information. "

A PPT was immediately changed on the big screen, showing a Xinzhou 700 regional airliner, and it was marked in different positions.

Looking at the marked information on the picture, Director Song of the Flight Test Center shook his head and voiced his opinion: "I don't think it's necessary to be so complicated, everyone thinks it's too complicated.

The acquisition of data does not necessarily require so many photoelectric observation equipment, in fact we can rely on some sensors to solve these problems.

For example, takeoff and landing, these data information can be obtained through relevant sensors. For example, a key data in takeoff and landing is speed.

Whether it is taking off or landing, it is controlling the speed. When taking off, the speed is required to be fast enough so that the plane can fly from the runway.

When landing, the speed needs to be slow enough so that the plane can land smoothly.

At present, the take-off and landing technology of drones is also very mature, and even some drones have achieved autonomous take-off and landing.

In this regard, we can learn from the technology in this area, and there is no need to submit manuscripts according to human thinking patterns. "

Wu Hao nodded with a smile when he heard the words, and then said immediately: "I agree with Director Song's words, it's true to fully obtain the dynamic data information outside the aircraft, but it doesn't have to be so complicated.

On the one hand, it is easy to increase the cost. On the other hand, the more equipment and the more complex the system, the more prone to failure.

In photoelectric observation technology, we also have some unique achievements. For example, the intelligent image recognition technology we use on various types of drones is very suitable for acting as the "eyes" of drones.

This technology can clearly identify the data information in the observation image of the optoelectronic equipment and perform corresponding processing, which can fully meet the needs of our project. "

Hearing Wu Hao's words, Director Song looked at Wu Hao and said, "I've heard about your image recognition technology for a long time. Let's talk about it later. I think there is great potential to be tapped."

No problem, I will ask someone to sort out a detailed information and send it to everyone later. Wu Hao nodded with a smile.
