A tilt rotor aircraft requires a lot of hard work and years of persistence to finally succeed. Just like a vertical take-off and landing fighter, many countries have tried their best to build one, but in the end, only two countries, Xiong Kingdom and Niu Kingdom, were formed and persisted.

Of course, these vertical take-off and landing fighters at the beginning have various disadvantages, such as small load capacity, short range, etc., but they can already be used after all, and it was not until the later F35 that it was finally achieved. This kind of vertical take-off and landing fighter can compete with normal fighters, especially this product is still a stealth aircraft.

Before there is no super powerful engine with a thrust-to-weight ratio of 10, Qin Guan couldn't be too expectant. Now let's talk about whether there is any or not.

The hardships and twists of the vertical take-off and landing aircraft of the propeller are similar to those of the vertical take-off and landing fighter. It took many years of hardship to finally achieve the right result.

What Qin Guan was looking for was of course the final mature aircraft. He liked the search engine developed by Lisa so much. After inputting it, he found what he needed.

Edwards Air Force Base.

This is the famous air force base of the Eagle Kingdom, and it also has the function of test flights. When Qin Guan came here, he saw the cv-22 Osprey that had completed his mission in a corner of the field.

At the beginning, the first batch of test flights were conducted here for many years, and the first batch of test aircraft had reached their lifespan, and this CV-22 model was the final improved model.

The first force that needs this kind of aircraft is the Marine Corps. When jumping from landing ships on the sea toward the ground, this kind of vertical take-off and landing aircraft is the most suitable.

Therefore, the Navy has been actively promoting this project. The Navy's MV22 Osprey has been tested for more than ten years, constantly eliminating various hidden dangers and finally achieving the ability to deploy in actual combat. Just after the Navy has matured this aircraft, the Air Force joined in and began to order the CV-22 Osprey needed by the Air Force. It was originally developed on the Navy model, so all kinds of defects have been made up.

After completing the test flight mission, the plane stayed here and quietly became history. Qin Guan approached and looked at this giant.

Compared with the Navy model, it does not need to be folded and is more simple. The fuselage looks like an ordinary helicopter, with a flat head and a square body, slightly short, while its wings on both sides are relatively short. In contrast, the two propellers on the wing tips look particularly wide, just like a small man wearing a big shirt.

In order to pull up the onion on dry land, pull it up directly, the propeller must be large enough, and that's it now. At the same time, the main secret of this aircraft is that the wing is the engine and propeller part.

The engines on both sides can rotate, driving the propeller to rotate, realize takeoff, hover and advance, and this process is also the most dangerous.

This engine is not only powerful, but also backups each other. In case one of them fails, the other can continue to provide power through the transmission shaft that runs across the entire wing to avoid the risk of crashes.

When it takes off and turns forward, its movements are very chic.

Qin Guan stopped in front of this plane for a long time.

The Eagle Kingdom is also studying it, but their research results are still early. The current prototype of Bell Company is less than half the size of this aircraft. Once it is launched, it will definitely have a sensational effect.

Qin Guan was waiting for the arrival of that scene.

Next, I have to find a chance to exchange it.

Since he came in this time, he was not busy going out immediately. In addition to looking for this thing, Qin Guan also had another thing to look for.

In addition to relying on our own super cannons, there is also a good thing, and of course the super rocket launcher!

Rocket launchers use their own power to propel. The biggest advantage is that their gun barrel is quite thin, and compared with ordinary guns, they are simply thin iron sheets, which brings weight advantages.

Ordinary artillery must have thick barrels, otherwise it will explode. Rocket launchers do not have to withstand the pressure of the chamber. They fly by the power of the rocket engine.

As early as ancient times, the Han Dynasty began to make rockets by itself. It can be said to be the prototype of modern rockets. However, the real shining was still in the war period. Nakatyusha was a weapon that made the enemy scared.

The rocket launcher has a low accuracy, but its coverage area is large. When multiple rockets are launched together, it is a killer weapon that makes the enemy scared, and there is nowhere to hide. All within the explosion range will be killed.

The general rocket launcher has a caliber of more than 100 millimeters and a range of dozens of kilometers. What about the Han Dynasty? The caliber has been continuously increased and the Guardian series of multiple rocket launchers with a range of nearly 400 kilometers has been developed. This rocket launcher installed on the chassis of the truck is a killer specially prepared for the opponent.

Because the range is too long and the error is too large, simple inertial guidance elements are simply installed to greatly improve the hit accuracy. At the same time, the cost is far smaller than that of short-range ballistic missiles, which are conventional weapons that can be used on a large scale in war.

This kind of rocket launcher is also an advanced equipment in 2020, so it is impossible for it to appear in weapons cemeteries in large quantities. Qin Guan can only look for its prototype car.

Continue to enter and search, and then Qin Guan came to the open-air warehouse of Han Guo Aerospace Industry Corporation. Here, there were indeed two Guard-2D prototype cars, which was the ultimate model!

The four-axle off-road launcher looks quite rough. Behind the body is a six-unit launcher. Han Guo started to like to use round launcher, but later it was changed to this square.

Although the shells are the same, the rockets equipped with internal equipment of the two cars are different, because one is exported and the other is used for its own use.

The exported one is 380 mm caliber, while the self-used one is said to be 420 mm caliber. If these two cars are exchanged, they will definitely be able to copy them soon. However, there is no need to worry. With these two cars, you can just pull them out during the military parade.

Moreover, it is said that it is for self-use, and it is also carried a drone and released before the attack. After the attack is completed, the drone needs to take a video to see the attack effect. The brains are full of praise.

That's all, you must exchange them all!
