Take Off My Aviation Era

Chapter 906: Large bypass ratio

Although subversion does not have much effect on actual combat, it has an incalculable impact on daily equipment and training.

As the saying goes, raising soldiers for a thousand days and using soldiers for a while, don't look at the time when they are used, but the key lies in the daily support, and the key to raising soldiers is to implement the military salary and the money.

Whether it is a turbofan engine or a turboprop engine, it is essentially a derivative of a jet engine. Although there are differences in maintenance, the difference is not bad. Because of this, the maintenance cost of a four-engine aircraft is inevitably higher than that of a double Send it high.

In addition, in terms of fuel economy, twin-engine aircraft also have unmatched advantages. Perhaps some people would think that turboprop engines will save fuel because of their unique mechanism.

To be honest, it is not necessarily true. Look at the engines of the An-12 produced in the Soviet Union, that are four live oil tigers.

The engine on the C-130 is not much better. After all, when the C-130 was designed, fuel economy was not considered as an indicator, so it was also a fuel-swallowing beast.

This is why after the Fourth Middle East War ended, when the US Air Force began to consider the successor to the C-130, it was an important reason for economy.

I am really afraid of being tossed by the oil embargo of the Middle East countries, and I want to get a new type of transport aircraft with better performance and better consumption ratio.

Only then has Boeing's YC-14 and McDonnell Douglas YC-15 duel.

However, the Americans later solved this problem by binding oil to the U.S. dollar by other means, so the replacement plan of the US military was not so urgent. Anyway, how the oil price jumps, is there the dominance of the American money printing machine?

So the so-called C-130 replacement plan is nothing more than that. Anyway, the US military is backed by U.S. dollars and it doesn't matter whether the fuel level is high or low.

At the same time, the Soviet Union was more arrogant than the Americans, because they themselves were the largest oil exporter, and Lao Tzu was the one who produced this stuff. All parts of the world are supplied by the Soviet Big Brother’s oil milk. Could it be that my family is short of it?

So what kind of oil tiger, what is the consumption ratio, is nothing to do with Big Brother Soviet Union, it's gone? It's easy to handle. It can be done with great effort to open an oil well. The other is that the site is large and the resources are sufficient!

The problem is that the United States and the Soviet Union have thick arms, so you don't need to care if their families are thick. How can other countries have thin arms and thin legs comparable?

What's more, the C-130 and An-12 medium-sized transport aircraft that are marketed in the world are old guys developed and produced in the 1950s and 1960s. Although the small improvements in various repairs have not been broken over the decades, they can be basically The structure is still the old objects and ideas of decades ago.

It would be fine if the combat styles and weaponry of various countries remain unchanged.

But with the development of the times and the advancement of science and technology, the militaries of various countries are not standing still, but are accelerating their development. Maybe what can be done by two light armored vehicles in the past, now requires two light tanks to barely complete.

The problem is that it was no problem to transport two light armored vehicles with C-130 or An-12 a few decades ago. Now let alone two light tanks, even if it is halved, it may not be able to be transported because the size of the light tank exceeds the size of the cabin. Size, what to do?

Want to order products from the US or the Soviet Union? That is definitely because the coffin of the national treasury has no place to spend, and he is ready to stretch his neck and let people be slaughtered.

Haven't ordered products to buy other products? I'm sorry, except for the C-130 and the An-12, the cheap medium-sized transport aircraft on the entire planet have no semicolon.

Just when all countries saw the world’s medium-sized transport planes gradually rushing, and they felt lifeless, and felt that it would take Ogg ten or twenty years to break the existing pattern, the luck of a large country in the East-17 is like a shock that tears away the twilight, and lights up. Countries look forward to the hope of the new Sinotrans.

Coupled with the cost advantage of twin engines and the actual performance of medium-sized rescue helicopters that can transport 6 to 8 tons, those who have used C-130 or An-12 for more than ten or two decades have long been used by these two grandpas. Of course, countries that are vomiting will be rushing.

"With a maximum load of 23.5 tons, it can perform a 2400-kilometer delivery mission. Although this is inferior to the C-130, it is much better than the An-12."

"Then what do you think, the maximum load of C-130 exceeds Yun-17. The problem is the delivery distance of the same load. C-130 is only about 1,500 kilometers, which is nearly a thousand kilometers away from Yun-17."

"Yes, look here. The size of the cabin is 12.7 meters in length, 3.4 meters in width, and 2.8 meters in height. It is completely straight through the cargo warehouse. The size and configuration of the C-130 are more reasonable. At least the legal light tanks we are equipped with can go up, even the American-made AH-1 "Cobra" gunships can also be installed."

"That's right, ordinary armored vehicles, light tanks and other combat vehicles can be put down completely. Even a 9-ton helicopter like the Black Hawk is fine. It can be seen that the transport capacity of the Yun-17 is still very strong."

"At present, I don't know what the actual situation is and how the basic flight quality is. If both are okay, we may formally issue an evaluation invitation to the manufacturer of Yun-17."

"Why don't we? To be honest, I have just sent someone to contact a certain big country in the east, but unfortunately there is too busy to reply..."

"Let me say that the actual performance and flight quality of Yun-17 is 50% of IL-76!"

While the military observers were discussing the actual situation of this model with the basic performance data of Yun-17, a loud voice suddenly sounded beside everyone, and I saw the Russian military observer Norokov. She was shy, looking at the people who were attracted by him with a cheerful smile, and said confidently: "This is not what I said, but the answer given by the experts of our Russia participating in the Yun-17 project. ."

As soon as this statement came out, one of the officer observers present was counted as one, all of them opened their mouths wide in shock, but before these people could react, Norokov's startling words came into everyone's ears again: "Yes. ~lightnovelpub.net~ Since the comrades of a certain big country in the East have made it public, then I can't hide it.

Yes, Yun-17 is the product of our cooperation between Russia and a big country in the East. Many Il-76 technologies are applied to it. The most iconic one is that Yun-17 uses two Russian-made D-30KP models. Turbofan engines, careful people should have noticed this..."

Speaking of this, Norokov paused deliberately to allow the military observers to digest it. Obviously, these military observers were not given for nothing. Naturally, they remembered the transport that had landed before. The long and narrow pod-type engine of the —76 transport aircraft could not help but believe Norokov's words seven or eighty eight.

Norokov saw that everyone was digesting the same, and the rhythm was firmly in his hands, and he smiled brightly and prepared to continue the topic, but before he could speak, there was a deep roar from the distant horizon, and immediately a fortune. The figure of —17 appeared in front of the personnel's field of vision against the backdrop of the snow-capped mountains.

In the end, it didn’t matter what it looked like. The sharp-eyed military observer immediately pointed at Yun-17, who was flying closer and closer, and shouted: "Look, this Yun-17 engine is not a D-30KP vortex with a small bypass ratio. The fan engine is a large bypass ratio, a large bypass ratio..."
