Siheyuan: Originally I just wanted to be a little transparent

Chapter 175 The relationship between spear and shield
"I agree with Mr. Lu's opinion!"

"I agree!"

Many experts and project personnel attending the meeting expressed their agreement.

"I also agree with General Engineer Lu's opinion. The design improvement plan proposed by Comrade Lin Shengli is indeed very good, but when we implement it, are there some problems? Are it a little difficult?"

"For example, the plan to use a new rocket ejection seat and install marine life-saving equipment."

"Our institute is currently studying this new equipment. The overall design structure and theoretical data can meet the technical requirements of the improvement plan. However, due to some problems with production equipment and raw materials, the fastest way to produce a sample that can be used on the machine is It will be more than three months later, will it delay Master Wu’s final assembly progress?”

"If we want to go faster, our superiors must provide us with sufficient equipment and material support as soon as possible."

Experts engaged in ejection seats and marine life-saving equipment mentioned the difficulties they encountered and the help they needed by expressing their stance at the meeting.

"Yes, the problems in our institute are more prominent. Other problems can be solved if we overcome them, or find similar replacements, or it takes time."

"But that tail guard warning device, let alone its own production, is now very difficult to even import from outside. As for research and development, it is completely blind, and there is no technical information to learn from."

"Besides, not to mention our research institute, even our Third Aircraft Department has never initiated a research project on tail protection warning devices."

"It is basically impossible to develop this tail protection warning device in such a short period of time!"

The person who spoke was Professor Tao, an expert in airborne radar research and design. Professor Tao is currently a leader in the field of radar research and the mainstay of their research institute.

He even said that if this tail protection warning device is not easy to operate, then it is really not easy to operate!

This tail guard warning device, to put it bluntly, can also be regarded as another disguised radar. (Tail guard warning device is also called radar warning device)
Speaking of which, we have to mention the relationship between airborne radar and radar warning devices.

The relationship between the two is that of a spear first and a shield later.

The airborne radar comes first, then the radar warning device; the missile comes first, and then the missile warning device.

The earliest airborne radar system appeared on the Yingjiang P series fighter aircraft in World War II. It was called the "radar gun sight". It was an exclusive "black technology" at the time. Before the Yingjiang aircraft crashed, the pilot had to manually dismantle it. You can only parachute by lowering the radar gun sight and throwing it to the ground or into the sea. Never let chickens get it.

The radar gun sight allows the enemy aircraft to be scanned from a distance of more than ten kilometers, and uses the radar signal as a ranging and aiming aid to shoot at the enemy aircraft within a distance of 1500 meters.

The biggest function of the radar gun sight is to detect enemy aircraft in advance, assist in ranging, aiming and shooting, so as to "find the enemy first and attack the enemy first", which is much more advanced than the optical sighting systems of other countries.

After World War II, Mao Xiong became very interested in Yingjiang's radar gun sight. Until the 50s Peninsula War, he still had no first-hand information or samples.

One day in October 51, Mao Xiong finally got it from an F-10 fighter plane that crash-landed on the beach on the coast of the peninsula.In order to ensure that the emergency landing aircraft would not be blown up by Eagle Sauce, Mao Xiong paid the price of losing 86 MiG-7s. Our comrades mobilized 15 people in the middle of the night to pull the aircraft back and forth from the beach.

Maoxiong's engineers came into contact with physical radar sights for the first time, and immediately developed the first radar warning receiver and installed it on the tail of the MiG-15, commonly known as the "tail protector".

The tail protector can detect the F-7's radar gun aiming frequency signal at a distance of 8 to 86 kilometers, reminding the pilot that there is an enemy aircraft following behind, giving the MiG-15 an eye on the back, which greatly improves the meter range. The battlefield survivability of the Ge-15 fighter jet.

While Mao Xiong was developing warning devices, he also imitated radar gun sights.

With the development of electronic technology, airborne radars have evolved from simple range-finding and gun-aiming radars to integrated search and fire control radars. Later, the most advanced ones were active phased array radars.

The functions of radar are nothing more than the following two: search and lock-on attack. Search is equivalent to scanning an area with a flashlight to find the target in the dark night; lock-on attack is like using a flashlight to illuminate the target in a directional manner in the dark night so that the target is always exposed to bright light. , and then throw a brick over!
Modern radar warning devices can distinguish between search and lock, as well as signals from different types of radars, thereby providing pilots with more accurate threat information.

Missile early warning is further divided into radar early warning and ultraviolet signal early warning. Medium and long-range air-to-air missiles have their own radar and can also be detected by warning devices.

The ultraviolet signal early warning device can detect the unique ultraviolet signal in the missile tail flame. At this time, there are only a few seconds before the missile arrives, and the interference bomb must be released immediately for final defense.

In fact, once the warning device receives the locked signal, it is already in an extremely passive state. If it is in the no-escape zone, that is, within the working distance of the air-to-air missile propulsion rocket engine, it will be difficult for the fighter plane to escape the fate of being shot down.

However, if the enemy radar is still in the search stage, the radar early warning device can still play a greater role.

However, with the use of data links, modern fighter jets will basically not turn on their engines to search for targets. Instead, they will directly conduct targeted fire control and lock attacks based on the air situation information provided by the early warning aircraft. The battle between spear and shield never stops for a moment!
As the saying goes, spears and shields complement each other. In the end, the development of this tail protection warning device has to fall on the people who develop airborne radars.

Everyone at the meeting spoke to each other. Although some raised difficulties, some made demands, and the words they said were different, everyone's opinions were the same and they all agreed very much. Using the information provided by Lin Shengli Design improvement plans.

Engineer Lu has some different views on the obstacles and difficulties that arise when everyone wants to implement the design improvement plan proposed by Lin Shengli.

After the radar professor Tao finished speaking, Mr. Lu continued:

"In the past few days, like everyone else, I have been studying the materials in my hand, and I have not gone to Comrade Lin Shengli to communicate with me."

"I think that since Comrade Lin Shengli can design such an advanced, practical and reasonable plan, then maybe he will have corresponding solutions to the obstacles and difficulties that arise during implementation."

"In addition, regarding some of the more prominent issues raised by Professor Tao and other experts just now, I think there are completely ways to solve them."

"What solution?" Upon hearing that there was a solution, several experts headed by Professor Tao quickly asked!
