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

As the so-called raising soldiers for a thousand days and using soldiers for a while, don't look at all kinds of cool when you use them, but the key lies in the maintenance on weekdays, and the key to raising them is to implement military salaries and money.

Whether it is a turbofan engine or a turboprop engine, it is essentially a derivative of a jet engine, although there is a difference in maintenance, but it is very different, and because of this, the maintenance cost of a four-engine aircraft is necessarily higher than that of a twin-engine.

In addition, in terms of fuel economy, twin-engine aircraft also have unbeatable advantages, and some people may think that turboprop engines will be very fuel-efficient because of their unique mechanism.

To be honest, not necessarily, just look at the engines of the Soviet-made An-12, which are four live oil tigers.

The engine on the C-130 is not much better, after all, fuel economy was not taken into account when the C-130 was designed, so it is also a fuel swallower.

This is also an important reason why, after the end of the Fourth Middle East War, when the US Air Force began to consider the successor model of the C-130, it proposed economy.

I was really scared by the oil embargo of Middle Eastern countries, and I wanted to get a new transport plane with better performance and better consumption ratio.

This is the strong showdown between Boeing's YC-14 and McDonnell Douglas' YC-15.

However, later the Americans tied oil to the dollar through other means to solve this problem, so the replacement plan of the US military was not so urgent.

So the so-called C-130 replacement plan is gone, anyway, the US military has the dollar backing, it doesn't matter how high the fuel is.

At the same time, the Soviet Union was even more arrogant than the Americans, because they themselves were the largest oil exporters, Lao Tzu produced this thing, and all over the world had to be fed with the oil milk of the big brother of the Soviet Union, could their own family be lacking?

So what kind of oil tiger, what consumption ratio, in the big brother of the Soviet Union, it is not a matter, there is no one? easy to do, open an oil well can be built vigorously, nothing else is a large territory, sufficient resources!

The problem is that the United States and the Soviet Union have thick arms and thick family backgrounds, so how can other countries compare with thin arms and legs?

What's more, the C-130 and An-12, the two medium-sized transport planes sold in the world, are old guys developed and produced in the fifties and sixties, although various tinkering and small improvements have not been broken over the past few decades, but the basic structure is still the old objects and old ideas of decades ago.

It would be fine if the combat styles and weapons and equipment of each country remained the same.

But with the development of the times and the progress of science and technology, the armies of various countries are not standing still, but are accelerating their development.

The problem is that a few decades ago there was no problem with transporting two light armored vehicles from the C-130 or An-12, but now let alone two light tanks, even if they are halved, they may not be able to transport them, because the size of the light tank exceeds the size of the cabin, what to do?

Asking for customized goods from the United States or the Soviet Union? That is definitely thinking that the little coffin book in the treasury of the country has no place to spend, and is ready to stretch out its neck and let people slaughter it.

Sorry, there are no mid-sized transport planes on the whole planet with good quality and low prices, except for the C-130 or the An-12, there is no semicolon.

Just when all countries are seeing that the world's medium-sized transport planes are gradually becoming more and more lifeless, and they feel that it will take 10 or 20 years for Augur to break the existing pattern, the Yun-17 of a certain big country in the East is like a frightening storm that tears through the twilight, lighting up the hope of all countries looking forward to the new Chinese transport.

Coupled with the cost advantage of the twin engine itself, as well as the actual performance of medium-sized rescue helicopters that can transport 6 to 8 tons, those countries that have used the C-130 or An-12 for more than ten or twenty years, and have long been made by these two old grandfathers to vomit, will of course rush to it.

"With a maximum load of 23.5 tons, it can carry out a delivery mission of 2,400 kilometers, which is inferior to the C-130, but it is much better than the An-12. ”

"Then what do you have to think, the maximum load of the C-130 is more than the Y-17, the problem is the delivery distance of the same load, the C-130 is only about 1,500 kilometers, and the Y-17 is nearly a thousand kilometers behind. ”

"That's right, you look here, the size of the cabin is 12.7 meters long, 3.4 meters wide, 2.8 meters high, completely through the cargo compartment, not only the kind of half-hanging cargo compartment that is sunk in the middle of the An-12, but also more reasonable than the size configuration of the C-130, at least the French light tank we are equipped with can go up, not to mention, even the American-made AH-1 'Cobra' helicopter gunship can also be installed. ”

"That's right, ordinary armored vehicles, light tanks and other combat vehicles can be put down, but even a 9-ton helicopter like the 'Black Hawk' is no problem, which shows that the carrying capacity of the Y-17 is still very strong. ”

"At the moment, we just don't know what the actual situation is and what the basic flight quality is, if both are okay, we may formally issue an evaluation invitation to the manufacturer of the Y-17. ”

"Why don't we, to be honest, I just sent someone to contact a big country in the East, but unfortunately it's too busy to reply to ......"

"Let me say that the actual efficiency and flight qualities of the Y-17 are 50% of that of the Il-76!"

Just when the military observers were discussing the actual situation of this model with the basic performance data of the Y-17, a loud voice suddenly sounded beside everyone, and they saw that the Russian military observer Norokov was shy, looking at the people who were attracted by his attention with a happy smile, and said quite confidently: "This is not what I said, but the answer given by our Russian experts involved in the Y-17 project." ”

As soon as these words came out, one of the officers and observers present was counted as one, and all of them opened their mouths in shock, but before these people could react, Norokov's astonishing words came into everyone's ears again: "Yes, since the comrades of a certain big country in the East have made it public, then it is not good for me to hide it."

That's right, the Y-17 is the product of our cooperation between Russia and a large country in the East, and it applies a lot of Il-76 technology, the most iconic of which is that the Y-17 uses two Russian-made D-30KP turbofan engines, and careful people should notice this......"

Speaking of this, Norokov deliberately paused for a moment, so that this group of military observers could digest it well, obviously these military observers were not given in vain, naturally remembering that the Y-17 that landed before was indeed using the same narrow pod engine as the Il-76 transport plane, and couldn't help but believe Norokov's words.

Seeing that everyone was almost digested and the rhythm was firmly in control, Norokov smiled brightly and was ready to continue the conversation, but before he could speak, a low roar came from the distant sky, and then a Y-17 appeared in front of the personnel's field of vision against the backdrop of the snow-capped mountains.

As a result, it didn't matter if this looked at it, and the sharp-eyed military observer immediately stretched out his hand and pointed at the Y-17, which was flying closer and closer, and shouted: "Look, the engine used by this Y-17 is not a D-30KP turbofan engine with a small bypass ratio, but a large bypass ratio, and a large bypass ratio ......."
