Bright Sword Military System

After asking Alberta in detail, Wang Xuexin understood why the total power of the two engines of Hans was not three times that of the eagle sauce engine, but the actual load was changed from 500 kg to 1500 kg.

In fact, the load capacity of FA223 is more than three times that of VS300. If FA223 is only used for short voyages with less fuel, it can even lift 2000 kg in extreme cases.

The reason this happens is because the first engine has too much horsepower to overcome the weight of the helicopter itself... which is the basic condition for the helicopter to take off, and then there is not much horsepower left to carry the weight.

If one more engine is added, most of its horsepower is used for load, so the total load will be much larger than that of only one engine.

"Then!" Wang Xuexin asked after hearing Albert's explanation, "Why don't we use two engines?"

"It's like this!" Major Albert took the briefcase under his arm, flipped through it for a while, and then took out a picture and handed it to Wang Xuexin: "This is Hans' FA223 helicopter!"

Wang Xuexin took the picture and looked at it. The first thing he felt was that the Osprey tilt-rotor helicopter was very similar to the modern eagle sauce. Install a propeller.

Wang Xuexin believes that the modern eagle sauce must have referenced the Hans FA223... This is not surprising at all. The eagle sauce during World War II was a veritable copying power. For example, the Springfield rifle was copied from Hans' Mauser rifle.

After the war, when the devils developed with the support of Ying Jiang, they also copied the big countries, copied or bought Ying Jiang's technology.

This is actually the only way for every country to industrialize and modernize... No country can innovate suddenly and suddenly. They must imitate, learn, imitate and learn again, and when they have learned these technologies and integrated them Only through penetration can we "stand on the shoulders of giants" to realize innovation.

It’s ridiculous that too many people on the modern Internet don’t know this. When Huaxia also develops according to this historical law, they always show a hatred or disdainful attitude towards Huaxia’s imitation and learning. This kind of condemnation, and even blame it on China's education and cultural problems, saying that China has no innovation ability and so on.

Fortunately, Huaxia insisted on going its own way, and finally developed to the point where it has now achieved catch-up and surpassed itself at the top of the world.

Seeing that Wang Xuexin looked at the picture silently, Alberta introduced: "Our helicopter does not have two swing arms, and there is only one engine, oil volume and propeller, while FA223 needs two, so FA223 Its own weight is one ton heavier than VS300!"

It is easy to understand that the two engines and two propellers of the FA223 will of course add more weight.

Alberta continued: "In addition, our engine only has 100 horsepower, so if it is designed like Hans, it will fall into a tasteless... The load capacity has not increased much, but the cost and fuel consumption have increased significantly..."

Wang Xuexin understood after listening.

In the final analysis, the engine output power of the eagle sauce is insufficient.

Insufficient power leads to a vicious cycle of adding more water to more noodles, and more noodles from more water: the added weight to accommodate two engines is enough to consume the horsepower of the other engine to nothing.

Hans' helicopter can do this only because its engine horsepower is 120 instead of 100.

Although it doesn't seem like much more than 20 horsepower per engine, it is precisely this extra 20 horsepower that plays a key role...the extra horsepower is completely used on the load.

As a result, the development of VS300 seems to have entered a dead end, and it can't even stack engines to improve performance.

At this time, Wang Xuexin seems to have only two choices:

One is to barely use this VS300 with unsatisfactory performance.

The second is to wait for Yingjiang to produce a more powerful engine.

There is nothing wrong with the former. If the Eighth Route Army is willing to accept it, it means that the transaction will go smoothly. Yingjiang is also happy to see this.

The latter is somewhat unrealistic... Even if Yingjiang produces a more powerful engine, they are not willing to provide it to the Eighth Route Army, and they will not even let the Eighth Route Army know.

Therefore, Wang Xuexin was not very willing to choose the two options. He didn't want the VS300 he had worked so hard to get on the battlefield to be useless... This would undoubtedly cause casualties to soldiers of the Eighth Route Army, including trained helicopter pilots.

After thinking about it for a while, Wang Xuexin had an idea.

To be precise, Wang Xuexin did not have an idea, but he thought of the "Mi-60" helicopter developed by Mao Xiong in the 12s.

The Mi-12 helicopter also imitates Hans' FA223... the shape and structure are also very similar, with a propeller on each of the left and right wings.

If there is any difference, it is that the "Mi-12" helicopter has 4 engines: two for each propeller, which was unexpected by the scientific researchers of this period.

Wang Xuexin hesitated for a moment, wondering if it was necessary to develop this idea without telling Yingjiang.

But Wang Xuexin finally gave up.

This idea is just the difference between knowing and not knowing. It is difficult not to know, but easy to know.

One day, Yingjiang saw the four-engine helicopter produced by the Eighth Route Army, and it took only a matter of minutes to realize production with its production capacity.

So is it still necessary to waste time and energy on independent research and development without telling them?
Therefore, Wang Xuexin took the picture of FA223 and said to Alberta: "Major, I am not satisfied with VS300, I hope to produce this kind of helicopter!"

"Comrade Commander!" Alberta shook her head and replied, "You don't seem to understand what I mean. I said that with the power of the Franklin engine, adding a rotor won't do much..."

"What if we add three engines instead of one?" Wang Xuexin interrupted Alberta.

"Three sets?"

"Yes!" Wang Xuexin said: "There are two engines for each rotor, and they use a gear structure to drive a propeller, so that the power of a single arm is 200 horsepower, and the whole machine has a total of 400 horsepower. Major, if this is the case, I believe it is The performance in terms of load, flight speed and ceiling will be greatly improved!"

Alberta looked at Wang Xuexin with disbelief.

One of the main reasons why the VS300 has not been able to achieve military use is that the engine power is not enough and the load is insufficient...Insufficient load means that it cannot carry many weapons and ammunition, and it is even worthless as a transport aircraft.

This problem has been bothering Yingjiang's scientific research team. I didn't expect it to be easily solved by the head of Huaxia now...
