Chapter 1553

Phased array radar, transmitting and receiving units, are small parts one by one. Each part can complete its mission. In this way, even if some units fail in operation, the rest can continue to work. Unlike ordinary radar, once the traveling wave tube is burned, the whole radar will lose its search ability.

At the same time, because it is a small part, how to arrange it is OK.

Now, looking at these people, Qin Guan began to explain. He picked up a one meter long stick and said: "Of course, this is an outer radome. Inside it, there is a radar antenna array. This antenna array is placed vertically. On the left and right sides, there are enough t / R units distributed in this slender area, so that we can have sufficient detection capability. Moreover, because this is slender, the resistance is very small, which is almost harmful to the aerodynamic layout of the aircraft At the same time, we can make full use of the size of the head and tail to make the length very large, which has great advantages over the disc early warning aircraft. The longer the antenna array, the larger the scanning airspace will be. "

Qin Guan didn't give an example. There's no need to give an example. Everyone can figure it out. Now his own early warning aircraft, a big guy of more than 100 tons, has a disk radome diameter of only about 9 meters, while the first balance beam early warning aircraft in later generations, that is, saab-340 "airy eye", can achieve a length of 9 meters on an 18 ton aircraft, which is absolutely advantageous.

Qin Guan's words plunged everyone into deep thinking. Soon, old Wang said, "but in this case, there is a blind spot in the scanning!"

Sure enough, ginger was still old and spicy, and old Wang saw the essence of the problem at once.

Our own early warning aircraft has a large plate on top of its head and an array on three sides. Each side controls 120 degrees, and three sides can control 360 degrees, which perfectly realizes 360 degree scanning.

However, this kind of balance beam early warning machine will not work. One side can be controlled at most 120 degrees and can be scanned on both sides. However, 60 degrees in front of the nose and 60 degrees behind the tail are blind areas.

Qin Guan nodded: "yes, this is a disadvantage of the balance beam early warning aircraft. However, this can be made up by the flight mode of the aircraft. When this early warning aircraft carries out early warning, it can scan all the surrounding areas by carrying out S-type flight."

The performance defects can be remedied through tactics. The scanning blind area of the balance beam early warning aircraft is remedied through flight mode. It can only scan both sides of the fuselage? Let the fuselage rotate continuously, won't it?

"That's ridiculous, isn't it?" someone said. If you fly back and forth like this, what's the advantage?

"The advantage is cheap." Qin Guan said, "early warning aircraft are multipliers of air combat power. All countries want to have such early warning aircraft. However, ordinary countries have limited funds and can not support our huge strategic early warning aircraft. Then they can only buy cheap early warning aircraft. No matter how bad it is, it's better than none."

Of course, the balance beam early-warning aircraft proposed by Qin Guan is mainly to make money and will be a main force of his own exports in the future. You know, the sale of early-warning aircraft is often dozens of times of profits, because only a few countries can develop early-warning aircraft.

Radish and celery have their own love. This strategic early warning aircraft must be a combination of large aircraft and disk radar. It is powerful, can scan all airspace, has no dead corner, and has the best performance. Therefore, this aircraft is suitable for countries with large land area, heavy combat tasks, strength and financial resources.

Look at later generations. It is clear that several countries are equipped with early warning aircraft of this level. Even the Han country itself is only equipped with a few. On the one hand, it is not easy to obtain Il-76 transport aircraft, on the other hand, it is also because it costs too much money.

With the combination of small and medium-sized aircraft platform and balance beam, large antenna is realized on small aircraft, but there is a blind area, which is very suitable for countries with small land area, small national strength, limited financial resources and less heavy combat tasks.

Of course, as far as future generations are concerned, the yun-8 early warning aircraft of the Han Dynasty have also developed two types, one is the air police 200 of the balance beam, and the other is the air police 500 of the big plate. In particular, the latter has successfully exported to the holy country and realized the export of advanced equipment such as early warning aircraft.

Now, Qin Guan said this kind of balance beam early warning machine. In this era, the Ellie eye early warning machine has not started to be developed. Qin Guan's eyes are quite advanced, and his advantages and disadvantages have been said. In this way, the technicians present nodded convincingly.

"Yes, we can develop such an early warning aircraft. Now our technology is mature. As long as we improve the algorithm, we can match it."

As long as the R & D of this large-scale early warning aircraft is completed and other improvements are made, it will be very easy. For example, if it becomes a balance beam, the control systems of T / R units need to be changed accordingly. This is very simple and easy.

Qin Guan nodded: "of course, this is the future development. Now, our main task is to complete the Tianzi No. 1 project, which is related to the national defense of the motherland. Everyone has worked hard."

After inspecting the progress of this early warning aircraft, Qin Guan was very encouraged. His own scientific researchers made this aircraft out at such a fast speed, leaving the final test flight. Of course, the test flight may encounter many problems. It will take them a long time to overcome these problems.

What about yourself? Of course, we also need to help. Exchange all the information of future air police 2000 early warning aircraft! In this way, they can complete the test faster and find a solution to the problem easier.

Qin Guan got off the early warning plane and planned to exchange information when he went back. Old Ma said, "Mr. Qin, thank you very much. Without you, the future of our plane is very slim."

Qin Guan nodded. Even now, the civil aviation department still doesn't want this kind of aircraft, and even began to choke on the engine. Qin Guan knows all this.

"Mr. Ma, this aircraft should first accumulate flight hours in the army and find more potential problems. For you, we should organize more personnel and strive to get the Western airworthiness certificate as soon as possible and pass the Western appraisal. In this way, we have the confidence to ask the Civil Aviation Administration."

Now, Qin Guan can't interfere too much. After all, his own plane is a new thing. It's reasonable for the other party to prevaricate with safety. However, when he gets the airworthiness certificate, it means that he meets the Western flight standards. At that time, if those people don't agree, they will fire at the civil aviation department!
