Take Off My Aviation Era

Not only the general manager of the turboshaft engine company was unbelievable, but also the heads of other "friends" were also full of consternation.

Nothing else because the power-to-weight ratio of the WD-63ZB turboshaft engine of Ascendas Group has reached 9.5.

What does this show?

Very simple, the WD-63ZB turboshaft engine can use the lightest weight and release more power. In other words, the WD-63ZB turboshaft engine is a super small steel gun.

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

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

Therefore, as long as the companies capable of producing turboshaft engines have all kinds of power-to-weight ratios, they are pursuing lighter weight and greater power.

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

However, this method is simple to say, but if it is really done, it is the most difficult industrial product in the world, not even one.

If this were not the case, there will not be only Americans in the world that can produce turboshaft engines with a power-to-weight ratio of 9 or more, and there will be one that can't even be seen by American taillights.

Even the former Soviet Union, which claims to surpass the United States in terms of heavy helicopters, is also a younger brother to the Americans.

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

Although it is very good compared with turboshaft engines in other countries, it is still far behind the turboshaft engines in the United States.

We must know that the United States is the latest model of CH-47D, the T55-L-712 high-power turboshaft engine of the same level as the WD-63ZB turboshaft engine. The maximum power is 3276 kW, but the total weight is only 340 kg.

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 reached an astonishing 10.2.

In addition, the two high-power turboshafts produced by the United States alone are not as powerful as the D-136, which seems to be overwhelmed by the Soviet Union or the Russians.

But this does not mean that the Americans cannot build a high-power turboshaft engine like the D-136, but because of their own mission requirements, it is not necessary to do so much.

Because both the "Chinook" and the "Super Sea Stallion", the US military requires the ability to take off and land normally on an aircraft carrier or an amphibious assault ship. This has led to the fact that the size of the two heavy helicopters cannot be expanded indefinitely, only in certain aspects. Make a choice.

In contrast, the Mi-26 heavy helicopter has no 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 had to make the helicopter bigger. Own needs.

In this respect, the US and Russian heavy helicopters do not matter which one is better, it's just that their needs are different.

But from the perspective of turboshaft engines, Americans have obvious technological advantages. Both materials and processes must be ahead of the former Soviet Union. In other words, different demands have caused Americans to prefer smaller sizes. But a heavy-duty helicopter with greater mission flexibility, otherwise, a model that is better than D-136

The high-power turboshaft engine is lighter, and the more powerful engine is really a matter of minutes.

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

Because of this, the world’s turboshaft engines are based on Americans. However, the more so, the more countries and companies feel that the United States’ technology is unattainable.

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

In particular, the experts and engineers of the so-called turboshaft manufacturing units really admire and fear American technology, and have a trace of jealousy.

It is this contradictory mentality that has led many domestic turboshaft engine manufacturers to be advanced and lofty in setting their goals; in the implementation, they are pro-American for a while, pro-Russian for a while, and in the middle are embracing Europe.

All in all, it is repeated horizontal jumps, without a solid long-term plan.

In addition, the persons in charge of these "friends" have tenures, ranging from five to six years, and as short as two to three years, and it is impossible to guarantee the continuous research and development of a long-term project.

After all, Xiao Gui and Cao Sui only exist in historical stories. In reality, whoever is in charge is really going to do this, and that shouldn't be said to be a idiot.

You don't even have the most basic business philosophy. Why do you come up here? It might as well be replaced by a dog.

Because of this, even if a certain "friend business" has a long-term R&D project, the model will progress with twists and turns due to the replacement of the person in charge.

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

As a result, doing this has made the already chaotic turboshaft engine research and development more magical or even fantasy.

In this situation, most models have no other way but to die.

But it's over, the people in charge of these "friends" also have a saying:

We are aiming at the world’s advanced level. However, the turboshaft engine technology is too difficult. We admit that there is a bet this time. We benchmarked the model indicators against the XX advanced turboshaft engines in the United States. The results proved that our country is in basic science, material research, and system integration. The aspect needs to be improved~www.readwn.com~ But even so, we are not for nothing, for example, in the engine shell...Balabara...

All in all, the extremely mature defensive skills have become a routine, no matter what the name changes.

It is nothing more than the United States is too advanced, we try to surpass, but our own foundation is too weak, even technically advanced Europeans can't handle it, how can we who are not as good as Europeans?

So failure is inevitable.

However, failure or failure is not nothing in the whole process, but a lot of experience has been summed up in many aspects, and many blanks have been filled. Based on this, we have launched a more specific model of XX. Leaders~~~ have time to help us approve A moment~~~~

In addition, the reading app I'm using recently, [\\mi\\mi\\read\\app\\\\] has many sources of books, complete books, and fast updates!

This time you can rest assured that you can take out the model samples, otherwise you don't need to say from the leader, I will make a chrysanthemum!

Anyway, no matter how you do it, the "friends" will always be right. The rest is the superior paying for it. As for what the turboshaft engine is made, it is not decided by the superior. It is totally not what you think, I I think the bossy president posture.

Under such a model and system, the life of the "friends" is a nourishment, not to mention that they are rich, and they have no worries about food and drink, which is absolutely the envy of various industries.

As a result, when the "friends" were collectively eating vegetarian meals, and were engaged in systemic dividends, the Ascendas Group's WD-63ZB high-power turboshaft engine was tantamount to a slap in the face, and a group of "friends" could not be found at all.

Didn’t you say that no one can reach the level of an American? How to take off the group, you can't?
