Take Off My Aviation Era

Chapter 1177: Real 4th generation machine

It was not only the army leader who accompanied the general leader who was surprised, but other leaders and chiefs with military background were also quite surprised.

No way, it's straight-the noise control level displayed by 8MAX is beyond the cognition of many people.

What is the external noise level of 85 decibels?

That is, the volume produced by the shuttle traffic on busy roads.

For most people, this volume may feel a bit noisy, but for a large helicopter equipped with a turboshaft engine, reducer, and propeller hub, and with a maximum take-off weight of 14.8 tons, it is almost as tickle.

To know the original version of the Zhi-8 helicopter of the same level, the outside volume of the French "Super Hornet" helicopter has reached 108 decibels.

Due to the imperfect system integration of the imitated old Z-8, the noise control is not as good as the imitated prototype, reaching 112 decibels, which is almost equal to the noise of the first-generation Z-5 helicopter.

This is why the French "Super Hornet" helicopter is clearly a large-scale maritime helicopter platform specially built by the French aviation industry for the French Navy. It should be changed to an excellent professional anti-submarine helicopter modification platform for the domestic navy, but after placement , An important reason for becoming a mascot that can only be publicized.

Its own noise is too loud, even if it integrates the most advanced airborne sonar detection equipment at the time, there is no way to accurately search for the exact location of the submarine.

Because of the roar of the three engines of ZH-8, the sonarman still wants to hear the sound of the seabed? The screen is full of vibrations from the helicopter itself!

Accompanied by loud noises, there are violent vibrations, and the vibration level is basically maintained at about 0.2 grams. That is to say, a two hundred catty fat man sitting on top of the body can clearly see the fat on his body like water waves. The same tumbling up and down, left and right.

Under such circumstances, what kind of precision detection equipment can stand?

It is estimated that before catching any submarine, the detection instrument fixed in the cabin was shaken apart by itself.

Based on this, even though the Navy in the 1980s and 1990s had the same level of platform as the "Neptune" helicopter, it did not turn into a classic shipborne helicopter like the "Neptune" helicopter. This is the key reason.

Later, I had to choose the smaller Zhi-9 as a carrier helicopter and assume the heavy responsibility of formation aviation anti-submarine, which is also the reason.

Because of the Z-9 prototype, the French "Dolphin" helicopter belongs to the third generation helicopter. The noise outside the cabin is controlled at 95 decibels, and the interior can reach 85 decibels. With other special technical processing, it can be used normally for airborne sonar detection. equipment.

The imitation Zhi-9 well inherited the noise reduction characteristics of the "Dolphin" helicopter, which was favored by the Navy.

In contrast, the Zhi-12 built by Ascendas Group is not as good as the Zhi-9 in this respect. The noise level outside the cabin is 98 to 102 decibels, and the cabin is basically maintained at around 90 decibels.

The vibration level is lower than that of the old straight 8 at 0.12 g, but greater than 0.1 g of the straight 9, so it has a great influence on the detection accuracy of underwater acoustic equipment.

Because of this, the Navy did not equip the Z-12 in large quantities, but only purchased a small amount. Even so, the few Z-12s were used by the Marine Corps. It can be seen that the Navy is not optimistic about the Z-12.

There is no way. The original development of Zhi-12 was more about solving problems. The consideration was not comprehensive, and some flaws were inevitable.

However, when it comes to Zhi-8MAX, it is different. Since it is clear that this is a ship-based helicopter for the Navy, then the combat environment and mission requirements of the Navy must be considered. Therefore, noise reduction and vibration reduction will inevitably become an important indicator to improve. .

Therefore, this improvement will "perfect" a world advanced level.

You must know that 85 decibels is just the noise level outside the cabin of 8MAX, only 60 decibels in the cabin.

60 decibels, the normal voice of the two people is at this level.

This is almost negligible in a helicopter with a complicated mechanical structure, but what is the level of vibration under such noise?

Recommended, [\\mi\\mi\\reading\\app\\\\] really good, it's worth installing, after all, you can cache books and read them offline!

"0.05 grams!"

Zhuang Jianye gave a very low figure, which is twice as high as the vibration level of the straight 9 helicopters that the Navy has now generally equipped.

Compared with the old straight 8 it is several times lower.

That is to say, a big fat man of two hundred catties sits naked, just like a Boeing 737 or Airbus A320 airliner. Not only will he not tremble all over, he will feel quite comfortable.

This is for the navy ocean-going formation...

"This is undoubtedly a huge boost for our future ocean-going naval fleet!"

Just when everyone, including the big leaders, began to try to imagine the combat composition of the naval formation, Zhuang Jianye gave the answer without hesitation. Not only that, Zhuang Jianye further said: "As just said, Zhi-8MAX The most important feature of this is quietness, but apart from being quiet, its space is large enough.

The current straight-8MAX premium VIP version has a cabin of only 6.5 meters, but the true naval type is 7.06 meters long. "

Speaking of Zhuang Jianye walking to the normal cabin in front, he hugged his hands in the middle of the cabin and made a big circle gesture: "So a 360-degree circular sea search radar will be set up below this position; then a hanging active type will be placed in this position. Deepwater sonar..."

Before he could speak, Zhuang Jianye went through the crowd again, walked to two-thirds of the cockpit, made a stroke on the couch, then walked quickly to the back of the cabin, pointed at two places and continued: "Here are two rings. Sonar Float Launcher~lightnovelpub.net~ Each device is equipped with 10 sonar buoys, two of which can carry a total of 20 sonar buoys."

After speaking and stepping back, he pointed to a location behind the blocked door in the middle of the cabin and said by introducing: "And this location can house the data processing computer and integrated communication equipment of the detection equipment. And here..." Zhuang Jianye took another shot. Outside the door: "It's the signal control and operation console. It can be set up with three or integrated into two, depending on the situation.

Finally, with the four light anti-submarine torpedoes and the retractable magnetic detector at the tail of the fuselage, and the 4.5-hour battery life, its combat capability is no less than that of a small fixed-wing anti-submarine patrol aircraft.

So only two to three straight-8MAX can provide quite advantageous anti-submarine alert and search for the ocean-going fleet..."

In the luxurious cabin of the Zhi-8MAX premium VIP, Zhuang Jianye described a comprehensive search, positioning, and positioning of sea search radar, magnetic detector, sonar buoy, active deep-water hoisting sonar, and light anti-submarine torpedo for the leaders and others. The internal situation of the attacked comprehensive anti-submarine helicopter.

The advanced nature is self-evident, not to mention others, the carrying capacity of 4 light torpedoes alone has far exceeded the current straight 9, let alone 4.5 hours of battery life, the card 28 imported from Russia The paper data is no more than that.

But the problem is...

"What you said is tempting, but the requirements for the platform are extremely high. Are you sure that your Zhi-8MAX is capable of it?" The military leader, an expert in the equipment field, frowned upon hearing this and was outspoken. Asked.

Zhuang Jianye responded calmly: "Of course it can be competent, because this straight-8MAX is a real fourth-generation machine!"
