Three helicopters, this has become Chen Yang's hope, although he was disappointed that he could not refine the fighter, but he still arrived in the hangar of the three helicopters.

It is still to let everyone go out, looking at the three military green helicopters, this is the mature aircraft researched by the Celestial Empire a few years ago, and it is also the basic configuration aircraft in the current Celestial Empire army, of course, it is not the top type, compared to the top type that is in service in a small amount, these three helicopters are also only the advanced level of the Celestial Empire, and they cannot reach the height of the international advanced level.

And although the helicopter is good, the advantages and disadvantages are also too obvious!

The helicopter is mainly composed of three major systems: fuselage and lift (including rotor and tail rotor), power and transmission, as well as airborne flight equipment. The rotor is generally driven by a turboshaft engine or piston engine through a mechanical transmission system composed of a propeller shaft and a reducer, and can also be driven by the reaction force generated by the jet at the tip of the propeller.

The maximum speed of the helicopter can reach more than 300km/h, the ultimate speed of the dive is nearly 400km/h, the practical ceiling can reach 6000 meters (the world record is 12450m), and the general range can reach about 600~800km. The transfer range of the internal and external auxiliary fuel tanks of the aircraft can reach more than 2000km. Depending on the need, the helicopter has different take-off weights.

At present, the largest heavy helicopter in service in the world is Lao Maozi's Mi-26 (with a maximum take-off weight of 56t and a payload of 20t). At present, the practical application is mechanically driven single-rotor helicopter and twin-rotor helicopter, of which single-rotor helicopter is the largest number.

Helicopter is essentially another aircraft different from airplanes, and its thrust, lift and maneuvering are relatively different from those of airplanes.

The shortcomings and advantages of the helicopter are also the reasons why Chen Yang is unwilling to be unable to refine fighters, in fact, although the helicopter plays a great role on the battlefield, it is obvious that it cannot have airspace rights by relying on it.

And in the modern warfare system. Air supremacy is an extremely critical point, and the role of fighter jets, that is, to create air supremacy, which helicopters do not have!

The outstanding feature of the helicopter is that it can do low-altitude (several meters above the ground), low-speed (starting from hovering and the direction of the nose does not change), especially can take off and land vertically in a small area.

Because of these characteristics, it has a wide range of uses and development prospects. In the military aspect, it has been widely used in ground attack, airborne landing, weapons delivery, logistics support, battlefield rescue, reconnaissance and patrol, command and control, communication and liaison, anti-submarine mine clearance, electronic countermeasures, etc.

In civil use, it is used in short-distance transportation, medical rescue, disaster relief and life-saving, emergency rescue, hoisting equipment, geological exploration, forest protection and fire fighting, aerial photography, etc.

But the advantage is good. It is also a multi-purpose aircraft, with a wide range of use space, but the disadvantages are also extremely obvious.

Compared with airplanes, helicopters have higher vibration and noise, larger maintenance and overhaul workload, higher use costs, lower speeds, and shorter ranges.

These are the shortcomings of helicopters, and the biggest shortcoming for Chen Yang is that he is still unable to fight in the air, and it is more actually tactical support. It's just a matter of matching the ground battlefield.

"Now it depends on whether refining can make up for these shortcomings after refining becomes a magic weapon, and most importantly, it must also have the ability to strike in the air, fortunately, the theoretical altitude can also fly at an altitude of 10,000 meters, now it depends on whether it can be refined, if it is refined. Maybe it may not be impossible to get air supremacy! ”

After searching for the information of the helicopter, Chen Yang felt a little comforted in his heart. If the helicopter really has this flight altitude, then after refining it into a magic weapon, it may be able to make the disadvantages of the helicopter smaller, but the advantages can be infinitely magnified.

"Whew, don't even be able to refine a helicopter!"

In fact, the complexity of helicopters is also quite high, and many countries do not even have advanced helicopter manufacturing technology. A country that can produce fighter jets may not be able to produce excellent helicopters.

However, Chen Yang knows that this is not to say that helicopters are better than fighter jets, but that the focus is different, and fighter jets are an important symbol of a great power after all. And helicopters, perhaps, are tactical, but the strategy is still fighters!

In fact, the technology is naturally more difficult for fighters, whether it is the explosive ability of the engine, or other things, there are greater requirements.

If it is possible, Chen Yang still hopes to be able to refine fighters, but now is not the time to pick fat and thin, although the fifth-level treasure refining system is awesome, but it may not be able to refine helicopters.

At this time, Chen Yang was a little hard, it seems that the fighter needs a sixth-level treasure refining system to be refined, and even the top ones don't know if the sixth-level is enough, maybe it is possible to have seventh, and the larger and more complex warships, whether they are cruisers or destroyers, are big guys, and it is estimated that they will need at least a seventh-level treasure refining system, or even an eighth-level!

"In this way, the existence of these awesome aircraft carriers is estimated to require at least a ninth-level treasure refining system, it seems that if I want to unify the Indochina Peninsula, I need at least a sixth-level or even seventh-level alchemy system, and the gap in advanced science and technology is also huge!"

This time, the fighter couldn't be refined, but it was like a basin of cold water, poured on the top of Chen Yang's head, making him understand that he had taken it for granted before, the crystallization of human science and technology is not so simple, with his current ability, it is still too far away to fight the world!

"If you want to fight the whole world, it is estimated that you need at least a ninth-level treasure refining system, which can refine a large number of aircraft carriers, or even higher!"

Chen Yang, who understood it at once, thought complicatedly in his heart, and then opened the Heaven and Earth Bagua Furnace and tried to see if he could refine the helicopter!

"I hope so!"

Chen Yang prayed in his heart, there was a hint of anxiety in his eyes, and then with a ding, his brows furrowed slightly, and then a flash of joy flashed.

"Perceive this item to be refined with a million prestige minimum!"

Suddenly, the treasure refining system said, and Chen Yang also understood it later, just like before, many things have the lowest refining standard, and also have the highest refining standard, but all along, he has automatically silently followed the highest refining standard, but he ignored it.

"Fortunately, this is a slightly inferior Celestial Empire helicopter, if it is a really awesome helicopter, it is estimated that it will not even be able to refine the minimum level!"

"The lowest is the lowest, it's better than not being able to refine!"

Chen Yang was a little afraid in his heart, thinking a little complicatedly, and then said in a low voice: "Refining! (To be continued......)
