Chapter 488

Although it's just so, Tengfei airlines, which has been pondering over European anti submarine equipment for quite a long time, has given a set of best combination plans.

One is the integrated detection system at the front end of the module, and the other is the magnetic anomaly detector extending from the middle to the last.

The integrated detection system is a retractable search radar equipped by Thomson company of France according to the French Navy's Atlantic antisubmarine patrol aircraft. Its technical blueprint is the anaps-38 sea facing radar on the US S-2 antisubmarine patrol aircraft. Thomson company uses its exquisite design and retractable unique functions for reference and transplants it to the Atlantic antisubmarine patrol aircraft.

However, due to the limited space of the belly box assembly of 02 antisubmarine aircraft and the complexity of the retractable mechanism, Tengfei Airlines did not inherit its retractable mode, but fixed the fairing in the front of the belly box assembly of 02 antisubmarine aircraft after aerodynamic optimization.

The space saved is equipped with the smart acoustic detector and sonar receiver designed by Thomson company of France for the unmanned anti submarine aircraft.

The semi cylindrical protrusion extending from the middle to the rear is a retractable magnetic anomaly detector, which is provided by British Aerospace Corporation. The technology source also comes from the United States. The magnetic anomaly detector on S-2 and S-3 antisubmarine aircraft is such a retractable structure.

In the mid-1970s, the British self-developed gannet antisubmarine aircraft wanted to be upgraded. One of the improvements was to install a set of retractable magnetic anomaly detector similar to S-2 and S-3 antisubmarine aircraft at the tail.

Technology patents and samples have been obtained from the United States, waiting for the British government to spend a lot of money.

As a result, under financial pressure, the British government at that time not only slashed the upgrade plan of the gannet antisubmarine aircraft, but also slashed the whole fleet of gannet antisubmarine aircraft.

In the face of the British government's decision to cut the leeks and dig the roots of the leeks, Bae is crying. The patents and samples bought at a high price can't be used, so they can only be locked in the technology room to eat ashes.

I thought this deal would fall through like this. As a result, actor company came up with an unmanned antisubmarine aircraft. When British aerospace company saw it, what a good takeover man! Without saying a word, it turned out a layer of ash of the retractable magnetic anomaly detector from the technology room. After careful packaging, it smashed it to actor company.

However, for BAE's magnetic anomaly detector, it's a rare good thing for take-off airlines.

Because there is no such thing, no matter how advanced the box assembly under the belly of aircraft 02 is, it can not be called an anti submarine mission assembly. At most, it can only be said that it is a patrol and reconnaissance assembly with the nature of anti submarine.

The reason is very simple, just because magnetic anomaly detector is the core detection equipment of anti submarine aircraft besides acoustic detection system. Even in some specific environments, magnetic anomaly detection equipment is more efficient and reliable than acoustic equipment.

The reason is that submarine can reduce its acoustic signal by various means, but it is difficult to hide all metal shell in the earth's magnetic field environment, especially in the process of submarine's moving, the strong electromagnetic signal generated by magnetic cutting is difficult to completely cover up.

Magnetic anomaly detector is based on this principle to accurately find the submarine hiding in the vast ocean.

Without this set of equipment, if only equipped with acoustic system, it would not be so efficient. After all, the power of sonar buoy launched by antisubmarine aircraft is not large, and it is also affected by ocean clutter, ocean current and other natural environment, so the accuracy is not high.

This is also the reason why before the Soviet Union's tu-142 was equipped with a magnetic anomaly detector, many people called it a long-range maritime patrol aircraft, rather than an anti submarine patrol aircraft. The main reason is that tu-142, in addition to its large size and long range, is not high in anti submarine efficiency, which is only one or two layers better than ordinary maritime patrol aircraft.

Because of this, without the retractable magnetic anomaly detector provided by British aerospace company, the improved an-26 with No.02 module will be able to survive in the technical path, which is the level of figure-142.

But with the magnetic anomaly detector, it's not the same. Even the interior of an-26 cabin is so rough due to temporary modification that even the seats are welded with steel bars and then put together with rubber cushions.

Air tight equipment and air-conditioning equipment, not to mention the two Mao, concise than later generations of clean water room even touching, fully embodies the fighting nation's simple but not simple unique character.

Not to mention compared with the comfortable and luxurious cockpit of plateau hawk C, the second-class plateau hawk B is inferior.

But even so, the improved an-26, which is equipped with a box under the belly of aircraft 02, can still be called an anti submarine patrol aircraft, because the retractable magnetic anomaly detector can accurately detect 300 meters underwater, and with the front-end sea search radar, it can search a radius of 200 kilometers.

Once a suspicious target is found, ten active and passive sonar buoys on both sides of the module can be released to locate the submarine more accurately.

The Soviet b-79 "Foxtrot" class conventional submarine and the American "sheshuiyu" sturgeon class nuclear submarine were discovered because of the retractable magnetic anomaly detector in the box assembly under the belly of aircraft 02. The strong magnetic signal returned wave by wave, which made the dynamic display of the two submarines not too clear.However, the anti submarine crew under Zhou Jiwei's command gave the Soviet conventional submarines to the 5506 warship under Chen Fang's command, while they focused on dealing with the American nuclear submarines.

As a result, Zhou Jiwei is just catching two submarines all at once. Song Changzheng's words will make his good mood lost.

"Fly your plane!"

Zhou Jiwei, who had been exposed, knew that he was wrong, so he simply stopped talking to song Changzheng. He replied with a painless look and said, "keep your speed. This fish below is much more cunning than the one you just forced."

Song Changzheng didn't go on. After all, he was still on a mission, so he chuckled and grasped the joystick in front of him to keep the plane at a steady low speed.

At the same time, he turned on the phone and was ready to report the current mission situation to the flagship of the eastern Alliance fleet. But just then, song Changzheng, who was just about to open his mouth, heard a murmur in his headset, which instantly covered the original clear call.

For a moment, several monitors in the engine room flashed wildly. Zhou Jiwei, who was still judging the position of the submarine, was stunned. He immediately frowned: "it's electronic interference again. Is it over?"
