Siheyuan starts from a good life

After the equipment arrived in the laboratory, everyone went out, leaving Jiang Yan alone in the laboratory. Seeing that everyone had gone out, Jiang Yan drove directly into his small space after closing the doors and windows.

In front of the computer in his own space, Jiang Yan began to collect information on this airborne fire control system.

He recognized this piece of equipment after seeing this airborne fire control system just now. This is Yingjiang's MA-3 fire control system. It is composed of an A-4 sight and an APG-30 radar range finder. The system is installed on the F-86 aircraft and is the main airborne fire control system on the Eagle aircraft today.

After operating in front of the computer, all the information about the airborne fire control system appeared in front of Jiang Yan. Seeing these data and drawings, Jiang Yan felt confident.

After a while, Jiang Yan came out of the laboratory and went directly to his office. He picked up the phone on his desk and called Minister Liu.

"Please rest assured, superiors, I promise to disassemble this instrument within one month and put it back intact. I will also draw the relevant technical drawings of this instrument within this time."

After receiving Jiang Yan's assurance, Minister Liu immediately assigned the urgent reverse mapping task to Jiang Yan to complete.

Moreover, the First Machinery Department also coordinated with relevant departments through superior leaders to give the highest priority to this urgent reverse mapping task.

Jiang Yan's original plan to give priority to manufacturing precision equipment at the Institute of the Third Ministry of Machinery was in vain.

After accepting this urgent reverse mapping task, Jiang Yan had to put down everything he was doing and give priority to completing this urgent task assigned by the First Machinery Department.

For the urgent task of reverse drawing, although the time is tight and the task is heavy, fortunately, with the support of data on the computer, the speed is still quite fast. I estimate that I will basically spend the next month in the laboratory. Fortunately, Jiang Yan's family knew the nature of Jiang Yan's work, so they were not surprised.

Due to confidentiality reasons, all the drawings could only be completed by Jiang Yan himself. The hard-working Jiang Yan once again started drawing drawings that he was unwilling to draw.

In order to study this machine, Jiang Yan tore this important instrument into pieces in the first few days, combined with the information on his computer, and drew very detailed relevant technical drawings.

The so-called airborne fire control system is a general term for various equipment on an aircraft used to control the projection direction, timing and density of aviation ammunition so that it can hit the target. Referred to as airborne fire control system. The quality of its performance is one of the important indicators of the aircraft's combat capabilities.

Airborne fire control systems can be divided into fighter fire control systems, attack aircraft or fighter-bomber fire control systems, bomber fire control systems and armed helicopter fire control systems according to the combat purpose of the aircraft. The one in Jiang Yanshou is the fire control system on the fighter jet. .

However, as long as this system is thoroughly understood, it is not difficult to deduce other types of fire control systems, because different fire control systems have different emphasis on their functions in air or ground attack, but they are basically The functionality is the same.

Specifically, it means searching, identifying, tracking and aiming at targets, guiding carrier aircraft to occupy enemy positions, and controlling the projection and guidance of ammunition (including air-to-surface missiles, air-to-air missiles, rockets, artillery shells, bombs, mines and torpedoes, etc.).

Airborne fire control systems are developed on the basis of aviation sights. In the mid-20s, countries such as John Bull and Eagle began to equip aircraft with radars, which were cross-linked with sights to form the earliest airborne fire control system. However, shooting and bombing were separate systems, and they could only be used during the day. Under simple weather conditions, a tail pursuit attack or horizontal or dive bombing can be carried out.

After the mid-50s, the airborne fire control system gradually developed to be capable of all-weather operations, control the projection of a variety of ammunition, and added anti-air interception attack methods.

From the mid-60s to the early 70s, due to the use of heads-up and downward-looking displays, pulse Doppler radars, photoelectric detection devices and digital fire control computers, as well as "rapid shooting", "continuous calculation of hit points", "continuous calculation" The application of technologies such as "bomb drop point" and missile "off-axis launch" enables the airborne fire control system to have all-weather, all-altitude, and all-direction combat capabilities, further improving search and tracking capabilities, anti-interference capabilities, and projection accuracy.

That’s why it is said that the quality of the fire control system is one of the important signs of the aircraft.

However, when Jiang Yan was copying the drawings, he discovered that Yingjiang's radar was not a pulse Doppler radar, but an old-fashioned radar. Its air detection was okay, but its ground detection was slightly poor due to the mountains and rivers. Weaker, otherwise most foreign countries would not have installed pulse Doppler radars in the early 1970s.

However, how to tell this radar to the country is a difficult task. Thinking about it makes me scratch my head. It cannot be done without a valid reason.

The fire control system provided by the state is only a preliminary version. However, Jiang Yan also upgraded this product based on the information on the computer.

It wasn't until the last day of the allotted time that Jiang Yan walked out of his laboratory. Since Jiang Yan entered the laboratory, no one has entered. Jiang Yan basically lives and eats in it. The secretary and the staff sent by superiors could only wait outside the door for Jiang Yan's orders.

"Xiao Song, please inform Minister Liu and ask him to send someone to take away the drawings and equipment." Jiang Yan pointed to a pile of information and intact equipment in the laboratory to the staff sent by the First Machinery Department. He spoke.

Just kidding, there are more than 10,000 drawings that one person can't finish, and there are all these equipments.

"Okay, I'll make the arrangements right now." Xiao Song ran back quickly after hearing this. After a while, he led a group of people back.

It turned out that since Jiang Yan started working, Minister Liu had specially sent a team of people to guard this place around the clock. They not only guarded it, but were also responsible for escorting it, otherwise they would not have moved so quickly.

Soon the equipment and related information arrived at Minister Liu.

When the comrades of the First Machinery Department received the news from Minister Liu, they were all surprised and didn't know what to say.

Although they had learned about Jiang Yan's related deeds and believed that as long as Jiang Yan was given enough time to copy this instrument, it would definitely not be a problem, but the time left for him in this mission was really too tight. Some, and the workload is so heavy.

Therefore, they did not expect Jiang Yan to complete all the replica drawings of this important instrument.

They felt that as long as Jiang Yan could draw some structural diagrams and parts drawings of the instrument and assemble the instrument completely, the task would be considered a success.

But they didn't expect that Jiang Yan actually drew all the drawings of this important instrument in this short period of time. After getting the equipment and drawings, the people from the First Machinery Department did not delay and immediately returned this important instrument and equipment to the comrades on the hidden front through the comrades in the relevant departments, and they returned it.

The Ninth Department of the First Machinery Department immediately organized relevant experts from the department to demonstrate the relevant drawings drawn by Jiang Yan.
