Chapter 910 (1/2)

The sale of red wine was just an episode, and baozixuan didn't care at all. Because he has a third share of the 82 year red wine production of the whole Bordeaux region, he may not be able to drink it alone for ten years.

Leon food is very good. It's also good if my mother has a chance to taste it one day. It's unrealistic to come to the United States. It's a good choice for the chef to go to Xiangjiang for door-to-door service. It can also be regarded as a good marriage. It may be used one day.

William Welsh Douglas and Bao Shoufu have been chatting, but they haven't fallen behind in drinking. Little Macdonald has not yet had any idea what Baijiu is. After a while, he was unconscious and couldn't cry.

Janice Dickinson was waiting on her side. At this time, she was as careful and considerate as her wife was taking care of her husband.

Old William drank almost the same, but he didn't forget his identity as an aircraft designer; He began to discuss the issue of the fourth generation fighter with Bao Zixuan.

There are two ways to divide fighter planes. The United States and the Soviet Union have different views. The Soviet Union is divided into ”five generations”; The US side has a generation less.

At the end of World War II, new technologies accumulated over the years emerged one after another, the most striking of which was the leap of air combat platform from propeller to jet. In the late 1940s, the United States and the Soviet Union were almost equipped with the first mature jet fighter F-86 and MiG-15 at the same time. At that time, the two sides did not divide the fighters into generations. After all, there was only one generation.

Until the first practical supersonic fighter F-100 appeared, the United States called it the second generation jet fighter, which left the Soviet Union behind not only in technology but also in name. At that time, this was absolutely unbearable. Therefore, the Soviet Union immediately responded to the MiG-19, also known as the second generation jet fighter, to show that it did not lag behind the United States.

The emergence of the second generation aircraft means that the F-86 and MiG-15 have naturally become the first generation of jet fighters, which has opened the era of intergenerational division of jet fighters. At the same time, two parallel division standards - American Standard and Soviet / Soviet standard have emerged.

As for the third generation aircraft, they focus on energy and emphasize close combat and fighting in the air. Focusing on the energy or power in the process of air combat, the third generation fighter can be said to be an upgraded version of the spiral aircraft in World War II, that is, it is fast, and its mobility and speed have been significantly improved.

The fourth generation fighter is good at hiding itself. It has good mobility and agility. It also has the ability of supersonic patrol, which is called ”4S”. The fifth generation and the fourth generation have a inheritance relationship, which has increased the aircraft survival ability and diversified its functions in the continuous experience summary. Therefore, each generation of fighters is a connecting link between the preceding and the following, and constantly improved to meet the needs of the times.

Old William smiled and said, ”what performance do you think the fourth generation fighter should have, so as to surpass the third generation fighter.”

This is a big problem, but baozixuan knows that old William can ask like this. He must have done relevant rehearsals and discussions. At least he has been engaged in research and development in this field, otherwise it is impossible to put forward the concept of four generations of machines.

Bao Zixuan smiled and said, ”it seems that senior William is testing me, so I'll talk about my point of view.”

”Although the United States and the Soviet Union have different views on the division of fighter algebra, they are almost the same as a whole; According to American standards, let's talk about my humble opinion. ”

”The third generation fighters currently in service, such as F14, F15, F-16, F-18, and the Soviet MiG-29 and Su-27, belong to the third generation fighters. It has good mobility and over the horizon attack capability. ”

”With the continuous progress of science and technology, the performance of weapons and equipment will also be greatly improved. With the existing fighter capability, the strategic strike capability of the U.S. or Soviet air force will not be recognized by the military. It is an indisputable fact that both sides are trying to improve the performance of weapons. Of course, heiyun also had relevant expectations. ”

”Heiyun group has formulated a 4S standard for the fourth generation fighters, which are super stealth capability, supersonic cruise capability, super maneuverability and super battlefield situational awareness!”

”Through the shape design, the electromagnetic wave can be scattered to other places, and the electromagnetic wave will not return, and the radar will not detect the existence of the aircraft. This is also the main principle of realizing stealth capability.”

”Radar waves can be absorbed to some extent by surface coated absorbing materials. Of course, the absorbing material plays an auxiliary role and can be optimized in some places where it is inconvenient to smooth stealth processing. ”

”There is infrared stealth - generally, special treatment is made at the engine nozzle to cool the jet flow as soon as possible, cool the outer surface of the engine as soon as possible, and reduce the infrared characteristics of the aircraft!”
