Chapter 1115 Ascendas Group can do it, why can¡¯t you?

Previous page        Return to Catalog        Next page

    Not only the general manager of the turboshaft engine company was in disbelief, but also the heads of other "friendly businessmen" were also filled with astonishment.

    No other reason than that the power-to-weight ratio of Ascendas Group¡¯s wd-63zb turboshaft engine actually reached 9.5.

    What does this mean?

    It¡¯s very simple. The wd-63zb turboshaft engine can release more power with the lightest weight. In other words, the wd-63zb turboshaft engine is a super small steel cannon.

    No way, if the measurement indicator of a turbofan engine is the thrust-to-weight ratio, then the turboshaft engine is the power-to-weight ratio.

    The greater the thrust-to-weight ratio, the higher the performance of the turbofan engine. The greater the same power-to-weight ratio, the more powerful the turboshaft engine.

    Therefore, as long as companies have the ability to produce turboshaft engines, they are all working hard on the power-to-weight ratio. What they are pursuing is to use lighter weight to obtain greater power.

    The problem is that this road is more difficult than that of a turbofan engine, because due to its unique structure, the turboshaft engine cannot use the fan to increase the work, and can only rely on simply increasing the temperature in front of the turbine to increase power.

    "However, this method sounds simple, but in practice it is one of the most difficult industrial products in the world, if not one of them.

    If this were not the case, Americans would not be the only ones in the world today who can produce turboshaft engines with a power-to-weight ratio of more than 9, and the remaining ones would not even be able to see the taillights of Americans.

    Even the former Soviet Union, which claims to have surpassed the United States in terms of heavy-duty helicopters, is still a younger brother to the Americans.

    Because the D-136 high-power turboshaft engine that the former Soviet Union was proud of has a super power of 8,500 kilowatts, but its overall weight reaches 1,050 kilograms, with a power-to-weight ratio of only 7.25.

    Although it is very good compared with the turboshaft engines of other countries, it is still far behind the American turboshaft engines.

    You must know that the latest model of the American ch-47d, the t55-l-712 high-power turboshaft engine, which is the same level as the wd-63zb turboshaft engine, has a maximum power of 3276 kilowatts, but the total weight is only 340 kilograms.

    The power-to-weight ratio reaches 9.8.

    As for the T64-GE-419 high-power turboshaft engine equipped for the "Super Sea Stallion", the power-to-weight ratio reaches an astonishing 10.2.

    In addition, if you look at the two high-power turboshafts in the United States, neither one is as powerful as the D-136. It seems to be overwhelmed by the Soviet Union or the Russians.

    But this does not mean that Americans cannot make high-power turboshaft engines like the D-136, but due to their own mission requirements, there is no need to do so.

    Because both the "Chinook" and the "Super Sea Stallion" are required by the US military to be able to take off and land normally on aircraft carriers or amphibious assault ships, this results in the size of the two heavy-duty helicopters not being able to be expanded indefinitely, and can only be used in certain aspects.  Make trade-offs.

    In contrast, the Mi-26 heavy-duty helicopter does not have similar concerns. In addition, the former Soviet Union has a vast territory, and Central Asia and the Far East are even more sparsely populated. Therefore, the Soviets can only satisfy their needs by making the helicopter larger.  own needs.

    From this point of view, it doesn¡¯t matter which of the American and Russian heavy-duty helicopters is better, it¡¯s just that they have different needs.

    But from the perspective of turboshaft engines, the technological advantages of the Americans are still very obvious. Both materials and processes are ahead of the former Soviet Union. In other words, the needs are different, which leads the Americans to only favor smaller sizes.  But a heavy-duty helicopter with greater mission flexibility, otherwise, make a helicopter that is better than the D-136

    High-power turboshaft engines are lighter, and engines with more power are really a matter of minutes.

    It is precisely because of this that the world's turboshaft engine industry, including the former Soviet Union and now Russia, recognizes that the United States is the No. 1 in turboshaft engines!

    Because of this, Americans are the benchmark for turboshaft engines around the world. However, the more this is the case, the more many countries and companies feel that American technology is unattainable.

    The same is true in Europe and South America, and even more so in China.

    Especially those experts and engineers in the so-called turboshaft manufacturing units, they really admire and fear American technology, and there is also a trace of jealousy.

    It is this contradictory mentality that causes many domestic turboshaft engine manufacturers to be ahead of the curve and lofty when setting goals; in terms of specific implementation, they are sometimes pro-American, sometimes pro-Russian, and sandwiched in the middle is to embrace Europe.

    In short, it¡¯s just jumping around again and again without a solid long-term plan.

    In addition, the heads of these "friendly businessmen" have terms of office, ranging from five or six years to two or three years, which makes it impossible to guarantee the continued research and development of a long-term project.

    After all, Xiao Gui and Cao Sui only existed in history.?In the story, if the person in charge actually did this, he would not be called a fool.

    ¡°You don¡¯t even have the most basic business philosophy, why are you here?  Might as well get a dog instead.

    Because of this, even if a "friendly business" has a long-term research and development project, the model progress will suffer twists and turns due to the change of person in charge.

    Either the personnel of the R&D team have changed, or the model specifications have been forced to be revised. Otherwise, how can we reflect the level and ability of the new person in charge?

    As a result, the already chaotic research and development of turboshaft engines has become more magical and even fantasy.

    Under such circumstances, most models have no other choice but to die.

    But it¡¯s over, the people in charge of these ¡°friendly businessmen¡± also have their say:

    We are aiming at the world's advanced level, but the technical difficulty of turboshaft engines is too great. We admit that this time there is an element of gambling, and the model indicators are benchmarked against the xx advanced turboshaft engines in the United States. The results prove that our country is advanced in basic science, materials research, and system integration.  There is still room for improvement.

    But even so, we have not gained nothing, for example, in terms of the engine casing blah blah blah

    ??????????????? All in all, the extremely mature defense techniques have become a routine, and they are applicable no matter which company changes its name.

    It is nothing more than that the United States is too advanced and we are trying to surpass it. However, our own foundation is too weak and even the technologically advanced Europeans cannot do it. How can we, who are not as good as the Europeans, do it?

    So failure is inevitable.

    However, failure or failure is not nothing in the whole process. We have summed up a lot of experience in many aspects and filled in many gaps. Based on this, we have launched a better and more specific model. The leader~~~ can help us approve it when he is free.  For a moment~~~~

    Don¡¯t worry this time, I guarantee that we can bring out samples of the model, otherwise I don¡¯t even need to tell the leader, I will make a chrysanthemum myself!

    Anyway, no matter how you do it, the "friends and businessmen" will never be wrong. All that's left is for the superiors to pay for it. As for the shape of the turboshaft engine, it is not decided by the superiors. It is not your opinion at all.  He wants to act like a domineering president to me.

    Under such a model and system, the lives of the "friends and businessmen" are so smooth. Not to mention being extremely rich, they also have no worries about food and drink. They are definitely the envy of all industries today.

    As a result, just when the "friends and businessmen" were collectively doing nothing and reaping the benefits of the system, Ascendas Group's wd-63zb high-power turboshaft engine was like a slap in the face, which made all the "friends and businessmen" completely unable to find their way.

    Didn¡¯t you say that no one can reach the level of Americans?  How come Ascendas Group can do it but you can't?
