Chapter 879 WD-60ML Turbofan Engine

Previous page        Return to Catalog        Next page

    ¡°You can¡¯t blame the military observer from North Africa for being so surprised. The engine of the Y-17 that passed over his head was completely different from the one two hours ago.

    It is a thick and short engine. Not to mention military observers like them who study equipment and tactics all day long, even a layman here can understand the new Yun-17 as long as his eyes are not blind.  It is essentially different from the previous one equipped with a D-30kp turbofan engine with a long and narrow engine room.

    It is obvious that this new Y-17 uses a brand new engine, and it is far superior to the large bypass ratio turbofan engine of the former Soviet Union's D-30kp turbofan engine.

    No way, the bypass ratio of the former Soviet Union's D-30kp turbofan engine was only 2.4. In the 1960s and 1970s when it was born, this indicator could only barely meet the border of a medium bypass ratio, let alone a large bypass ratio.  In comparison, even the second-class high-bypass roads are far behind.

    In the 1990s, as the three aerospace giants General Motors, Pratt & Whitney and Rolls-Royce successively launched a new generation of large bypass ratio aero engines with a bypass ratio of more than 10, the D-30kp turbofan engine had some other aspects besides thrust.  Except for the head, other aspects have lagged behind the times.

    But even the thrust that the D-30kp turbofan engine is proud of is nothing worthy of praise, because it is obtained at the expense of part of the maintainability, the life of the entire machine and high fuel consumption.

    No matter what else, but in terms of the overhaul interval, most similar European and American engines last about 10,000 hours, while the D-30kp turbofan engine only has a meager 3,000 hours, which is only one-third of similar European and American products.

    As the saying goes, one can tell the world from one leaf, so it can be seen that the D-30kp turbofan engine is really not as good as imagined.

    The military observers from various countries at the scene are all senior people in the industry. Naturally, they know the shortcomings of the D-30kp turbofan engine, so Norokov boldly said that the Y-17 uses the D-30kp turbofan engine.  , and when it was jointly developed with Russia, many people were surprised and frowned.

    Because in the eyes of most people, the d-30kp turbofan engine is not a good choice. Instead, it is better to use aero engines from large civilian airliners. Perhaps under field conditions, this type of civilian engine is not as good as the d-30kp turbofan engine.  Fan engine comes professionally.

    The problem is that all countries in the world cannot actually be in a state of war. Ordinary training is still the mainstream, and the characteristics of civilian large bypasses, which have greater thrust than engines, are fuel-efficient, and are easy to maintain, can greatly reduce the cost of daily training in various countries. If it is  In this way, more countries may choose Yun-17.

    Just when everyone was sighing in their hearts, the Y-17 equipped with a high bypass ratio turbofan engine suddenly appeared from behind the snow-capped mountains as if it was sentient, so that some military observers who were slow to react could not believe their eyes.  I thought I was dreaming, how could anything come to mind? There must be something wrong with my eyes.

    So after rubbing it again and again, I looked up at the sky and found that the engine of the Y-17 was indeed different. Then I suddenly realized that their "dream came true".

    The other military observers were happy, but Norokov, who had just let out the big words, was embarrassed.

    The reason why he said that the Yun-17 was jointly developed with Russia was because he wanted to use this frivolous method to coerce a big country in the East and let Russia get a share of the Yun-17 project.

    You must know that Norokov has seen the enthusiasm of military observers from various countries for the Yun-17. As a technical officer of the former Soviet Airborne Forces, how could Norokov not see the broad market prospects of the Yun-17.

    Not to mention other countries, even Russia, which inherited the Soviet Union's huge transport fleet, will probably drool when seeing the Y-17. There is no way that the aging rate of medium-sized transport aircraft such as the An-12 in Russia is even more serious, so Russia's medium-sized transport aircraft  Not only is the demand no lower than that of other countries, it is even stronger.

    Because of this, Norokov was equally shocked the moment he saw the Yun-17, but the next moment he made up his mind that this project must be in the hands of the Russians.

    This not only solves the problem of upgrading Russia's medium-sized transport aircraft, but also makes a lot of money in the international market.

    As for whether a big country in the East would protest against this kind of plundering, Norokov never thought about it. The reason is very simple. He didn¡¯t see that the Y-17 uses the D-30kp turbofan engine produced in the former Soviet Union.  Well.

    What does this mean?

    A certain large country in the East does not have a large-thrust aeroengine suitable for transport-17.

    Think about it, the largest power source for transport aircraft in a large Eastern country is just the WD-52ml turbofan engine with a thrust of 5.2 tons produced by Ascendas Group. The two together are not as good as one D-30kp turbofan engine. After all,  d¡ª30kp type turbofan engineThe thrust of the engine reaches 12.5 tons.

    " If you want to leap from 5.2 tons to more than 10 tons, it may not be possible to understand it at the level of a large Eastern country in 10 years. In this case, it is equivalent to saying that a large Eastern country is stuck in the neck when it comes to large thrust engines.

    The aviation engines of Western countries are good. The problem is that their engines cannot be used by outsiders for military purposes. Since the West has no choice, they can only use their Russian products.

    The only thing is monopoly. With monopoly, you can be superior, and if you are superior, you can do whatever you want.

    Because of this, Norokov's logic is very simple. I am blatantly cheating. What can you, a big country in the East, do to me?  Come and bite me if you have the ability, but you have to think carefully before biting, the D-30kp turbofan engine is the only one, soheheheit's better to put on a good posture and don't resist, the fighting nation is still very gentle!

    ???????????????????????????????????????????????????????????????????????????????????????The first one came was powered by the former Soviet Union¡¯s D-30kp turbofan engine, and the second one that came over in a blink of an eye was a brand new high bypass ratio turbofan engine.

    Not to mention low consumption and fuel saving, the weight is also much lighter than the D-30kp turbofan engine. More importantly, the thrust of this large bypass ratio turbofan engine is usually not low, at least it is the same as the D-30kp turbofan engine.  A level one for turbofan engines.

    This not only completely destroyed Norokov's plot to make trouble, but also made him embarrassed and unable to get off the stage. There was no way, what he said before was too full, and now the second Y-17 flew over and slapped Norokov in the face.  What did my husband say? Is it possible to admit that what I just said was just bragging to get in touch with Ci'er~~~?

    It doesn't matter if this is done at home. The key is in front of military observers from various countries, and many of them are little brothers from the former Soviet republics. If the Russian big brother confesses this, his own image, which is not very tall, will inevitably be affected.  It will shrink further in the hearts of these little brothers.

    So he had to hold on to this situation no matter what, so Norokov rolled his eyes, his heart skipped a beat, coughed twice to relieve the embarrassment, and pointed at Luck-17 falling on the runway and said with a smile: "I didn't expect Luck.  The latest facelift of the ¡ª17 uses our latest Russian PS-90 turbofan engine, haha, that is the high-thrust engine equipped on the Russian presidential plane"

    "Hey~ Norokov, let me correct you. The newly arrived Yun-17 uses our purely domestic WD-60ml large bypass ratio turbofan engine. I have never heard of a PS-90 turbofan engine.  "

    Before Norokov finished speaking, a slightly hoarse voice came from behind him, abruptly interrupting Norokov's pretentious words.

    Everyone followed the sound and saw that Zheng Quanli had arrived at them without knowing when.
