Chapter 878 Large Auxiliary Ratio

Previous page        Return to Catalog        Next page

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

    As the saying goes, it takes a thousand days to raise an army, but it takes a while to use it. No matter how good it is when you use it, the key lies in daily maintenance, and the key to maintenance is to implement military pay and money.

    Whether it is a turbofan engine or a turboprop engine, they are essentially derivatives of a jet engine. Although there are differences in maintenance, they are very similar. Because of this, the maintenance cost of a four-engine aircraft is bound to be higher than that of a two-engine aircraft.  The hair should be high.

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

    To be honest, it¡¯s not necessarily true. Look at the engines equipped with the An-12 produced in the Soviet Union. They are four real oil tigers.

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

    This is why after the end of the Fourth Middle East War, when the U.S. Air Force began to consider the successor model of the C-130, economics was an important reason.

    I am really scared of the oil embargo in the Middle East countries, and I want to build a new transport aircraft with better performance and better consumption ratio.

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

    But later, the Americans solved this problem by tying oil to the U.S. dollar through other means, so the U.S. military¡¯s replacement plan was not so urgent. Anyway, no matter how the oil price jumped, could it be as overbearing as the American money printing machine?

    So the so-called replacement plan for the C-130 came to nothing. Anyway, the US military is backed by US dollars, so it doesn¡¯t matter the fuel level.

    At the same time, the Soviet Union was even more arrogant than the Americans because they were the largest oil exporting country. I was the one who produced this stuff. All parts of the world needed oil from the Soviet Union¡¯s big brother. How could they lack it?

    ????????????????????????????????????????????????????????????????????????????????? Gas-fueled tigers, and what kind of consumption ratio, are nothing to do with the big brother of the Soviet Union, are they gone?  It's easy to handle, and it takes a lot of effort to open an oil well. The other thing is that it has a large land and sufficient resources!

    The problem is that the United States and the Soviet Union don¡¯t care if they have thick arms and rich family backgrounds, but how can they compare to other countries with thin arms and thin legs?

    What's more, the C-130 and An-12, two medium-sized transport aircraft marketed around the world, were developed and produced in the 1950s and 1960s. Although various small improvements have been made over the decades, they are basically  The structure is still the same old objects and ideas from decades ago.

    ¡°It wouldn¡¯t matter if the combat styles and weapons and equipment of each country remain the same.

    But with the development of the times and the advancement of science and technology, the armies of various countries are not standing still, but are accelerating their development. Maybe two light armored vehicles could do things in the past, but now they need two light tanks to barely complete it.

    The problem is that a few decades ago, the C-130 or An-12 could transport two light armored vehicles without any problem. Now, let alone two light tanks, even if they are reduced by half, they may not be able to transport them because the size of the light tank exceeds the cabin.  Size, what to do?

    Requesting customized products from the United States or the Soviet Union?  That's definitely because the country's treasury has little room for coffins and is ready to stretch its neck to be brutally slaughtered.

    No customized products to buy other products?  Sorry, the only high-quality and low-priced medium-sized transport aircraft on the planet is the C-130, which is the An-12.

    Just when all countries are watching the world's medium-sized transport aircraft gradually become silent and lifeless, and feel that it will take another ten or twenty years to break the current pattern, the destiny of a certain big country in the East is like a sudden moment that tears apart the twilight atmosphere and lights up.  Countries are looking forward to the hope of the New China Movement.

    Coupled with the cost advantage of the dual-engine itself and the actual performance of being able to transport 6 to 8-ton medium-sized rescue helicopters, those who have used the C-130 or An-12 for more than ten or twenty years have long been replaced by these two grandfathers.  Of course, countries that are going to vomit will follow suit.

    "With a maximum payload of 23.5 tons, it can perform a delivery mission of 2,400 kilometers. Although this is inferior to the C-130, it is much better than the An-12."

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

    "That's right, look at this. The dimensions of the cabin are 12.7 meters long, 3.4 meters wide, and 2.8 meters high. It is completely connected to the cargo warehouse. Not only is it better than the half-sized cargo warehouse of the An-12 with a piece of it sunk in the middle, but it is also smaller than the An-12.  The size and configuration of the C-130 is more reasonable. At the very least, it can fit not only the French-made light tanks we equip, but also the American-made AH-1 'Cobra' armed helicopter."

      "That's right. General armored vehicles, light tanks and other combat vehicles can be accommodated. However, even 9-ton helicopters such as the 'Black Hawk' are no problem. It can be seen that the carrying capacity of the Y-17 is still very powerful.  .¡±

    ¡°At present, we just don¡¯t know what the actual situation is like and what the basic flight quality is. If there are no problems with both of these, we may formally issue an evaluation invitation to the manufacturer of the Y-17.¡±

    "Why don't we? To be honest, I have just sent someone to contact a big country in the East. Unfortunately, they are too busy and have no time to reply"

    "Let me say, the actual performance and flight quality of the Y-17 are 50% of that of the IL-76!"

    Just when many military observers were discussing the actual situation of this model with the basic performance data of the Y-17, a loud voice suddenly sounded next to everyone. Following the sound, only the Russian military observer Norokov was seen.  With a chubby belly, he looked at the people who had attracted his attention with a pleasant smile, and said quite confidently: "This is not what I said, but the answer given by our Russian experts involved in the Yun-17 project.  .¡±

    As soon as these words came out, every one of the officers and observers present were so shocked that they opened their mouths. But before these people could react, Norokov's shocking words came to everyone's ears again: "Yes.  , now that comrades from a certain big country in the East have made it public, I can no longer hide it.

    Yes, the Yun-17 is the product of our cooperation between Russia and a big country in the East. It uses a lot of Ilyushin-76 technology. The most iconic one is that the Yun-17 uses two Russian-made D-30kp models.  Turbofan engine, careful people should have noticed this"

    At this point, Norokov deliberately paused to let the group of military observers digest it. Obviously, these military observers were not given for free. Naturally, he remembered that the Y-17 that landed before was indeed using the same aircraft as the Ilyushin.  The same long and narrow pod-type engine as the -76 transport aircraft, I can't help but believe Norokov's words.

    Seeing that everyone had almost digested it and that the rhythm was firmly in his hands, Norokov smiled brightly and prepared to continue the topic, but before he could speak, there was a low roar from the horizon in the distance, and soon a plane  ¡ª17's figure appeared in front of the personnel's field of vision against the backdrop of the snow-capped mountains.

    As a result, this sight did not matter. The sharp-eyed military observer immediately pointed at the Yun-17 flying closer and shouted: "Look, the engine used by this Yun-17 is not a D-30kp turbo with a small bypass ratio."  Fan engines have a large bypass ratio, a large bypass ratio"
