Luo Kai shook his head repeatedly, then looked at Wu Hao very seriously and said: "No, you are not naive, let alone immature. But you have lofty ambitions and a sense of national and national mission and responsibility that many people lack.
Your passion has not been in vain. We all see what you do and your hard work. The leaders and chiefs see it, and so do the people across the country.
Don't be discouraged, and don't give up. Please believe that there are 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.
Academician Tang Shizhen put on her reading glasses and, with the help of her assistant, used PPT to speak to everyone.
“No matter which control method we choose, whether it is remote control technology, automatic control technology, or a combination of the two.
All automatic control technologies have a premise, that is, the platform they are equipped with must be sufficiently automated, digital, and intelligent.
In layman's terms, the aircraft model targeted must be sufficiently advanced and must have strong dynamic perception capabilities.
Otherwise, no matter how advanced our intelligent driverless system is, we can't use it on old models like Yun 5 or Yun 7.
The control of these aircraft depends entirely on mechanical power transmission, or even purely mechanical transmission control. It is simply impossible to modify these aircraft.
Therefore, I think it is very appropriate for Deputy Director Qi to propose using the MA 700 model as our modification experimental platform. "
Having said this, Academician Tang Shizhen changed a PPT, which showed a picture of a MA700 aircraft in flight.
"Although this MA700 regional passenger aircraft is sufficiently advanced and the digital flight control system meets our requirements, it is not enough for our project. It lacks the external dynamic perception capabilities we need.
The so-called dynamic perception capability refers to the aircraft's ability to acquire external information, which includes radar on the aircraft and various flight sensors, such as airspeed indicator, altimeter, level gauge, and barometer.
It even includes some surveillance cameras outside the aircraft and radio receiving devices, which are important components of the dynamic perception system.
The external data information transmitted back by these data will assist the pilot to control the aircraft and meet the pilot's needs for flying the aircraft.
But this is far from enough for our intelligent driverless system.
First of all, the system is not a human being. It does not have the sensory organs of the human body, such as vision, touch, hearing, and smell. The most important ones are vision and hearing.
As for the system, it needs to receive this data through various devices.
In fact, during air flight, most rely on radar to observe the situation ahead, and rarely use visual inspection directly. Visual vision is generally used for takeoff and landing, as well as some emergency situations.
Of course, what I am talking about here is civil aviation passenger aircraft and transport aircraft, 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 pilots to have sharp visual observation capabilities.
The same is true for the system, which also requires strong visual ability. "
"In this regard, we have synthetic aperture radar and photoelectric pods that will be widely used on UAVs. The technology in this area is very mature and we can install it directly on the aircraft." Director Song from the flight test center interjected.
——————
Academician Tang Shizhen put down the tea cup in his hand, then nodded and said: "Yes, but it is not enough. This type of photoelectric pod can satisfy general small drones or aircraft, but it cannot satisfy medium-sized and large aircraft. For example, medium-sized and large aircraft Its huge body can block the large field of view of this type of photoelectric pod, resulting in incomplete observations.
No matter how advanced the photoelectric observation equipment is, there is still a difference between them and what we see with real human eyes.
Therefore, if you want to realize automatic control or remote control, the vision problem must be solved first.
In this regard, we have specially set up a photoelectric observation system research team, and they have put forward a preliminary design plan.
That is, multiple photoelectric observation devices are installed at different locations on the entire aircraft to facilitate the system and our remotely controlled pilots to better control dynamic data information. "
A PPT was immediately changed on the big screen, which showed a MA700 regional airliner, and there were markings on it at different locations.
Looking at the annotated information on the picture, Director Song of the Flight Test Center shook his head and raised his voice to express his opinion: "I don't think it is necessary to be so complicated. Everyone makes it too complicated.
The acquisition of data does not necessarily require so many photoelectric observation equipment. In fact, we can completely 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 taking off or landing, you are controlling the speed. When taking off, the speed is required to be fast enough so that the plane can fly off the runway.
When landing, the speed needs to be slow enough so that the aircraft can land smoothly.
At present, the take-off and landing technology of drones is also very mature, and some drones have even achieved autonomous take-off and landing.
In this regard, we can learn from the technology in this area. There is no need to write the manuscript according to human thinking patterns. "
Wu Hao smiled and nodded when he heard this, and then said immediately: "I agree with Director Song, it is true to fully obtain the dynamic data information outside the aircraft, but it does not need to be so complicated.
On the one hand, it is easy to increase costs. On the other hand, the more equipment there are, the more complex the system is and the more likely it is to malfunction.
We also have some unique achievements in photoelectric observation technology. For example, the intelligent image recognition technology we use on various types of drones is very suitable to serve as the 'eyes' of drones.
This technology can very clearly identify the data information in the observation images of photoelectric equipment and process it accordingly. This aspect can fully meet the needs of our project. "
Hearing Wu Hao's words, Director Song looked at Wu Hao and said, "I have heard about your image recognition technology for a long time. We will have more exchanges in this regard. I think there is great potential that can be tapped."
No problem, I will ask someone to compile a detailed information and send it to everyone. Wu Hao smiled and nodded.
