CC, the fastest update power king!

Looking at Liu Xiaofeng's appearance, Wang Da Zhi took the initiative to pick up the words: "Liu always thinks that since it is a medium-sized tactical transporter, it should use propeller engine, and then look at the mainstream medium of the world today. The tactical transporter and the light transporter basically use local turbine propeller engines, so your heart is probably in the middle of the following transport planes, the best power partner is the turbine propeller engine, what is this? "

"Yes, I mean this."

Liu Xiaofeng nodded, and his heart was really thinking.

"Haha ... I will know that it is like this."

Wang Dazhi smiled nodded: "Mr. Liu, I want to say that your old idea really needs to be re-adaptive to the development of the era.

What you mean this is not to say that I am an old brain, is my brain can't keep up with the development of the times? Liu Xiaofeng's heart is somewhat uncomfortable, but more still not convinced: Your Wang Da Zhi can be a lot more than me Liu Xiaofeng, big teenage, what do you say? "I know that I will say that Liu, you will definitely don't care, then let's talk,"

Wang Da Zhi said: "Liu, you said, when Mi Lijian and the old Maozi were developing a medium-sized tactical transport plane, why didn't I use a jet engine but turbine propeller engine?"

Liu Xiaofeng said: "Is this still used? Of course, because of the An-12 or C-130, they have been immediately in the 1950s, the most advanced aerospace engine is a scroll in addition to the vortex, there is no The scroll, compared to the vortex spray, the oil consumption of the scrubtap paddle is much lower. Of course, it is necessary to use a scroll.

"now it's right,"

Wang Dazhi took a shot of the thigh: "This is also life, when Miliejian and the Soviet Union develop medium-sized tactical transport aircraft, it is because the scroll engine is the most suitable engine at that time, but now, compared to vortex Does the fan engine, the need for the oil consumption in the fuel consumption? Taking into account the turntile engine can provide a higher flight speed to the aircraft, then why should we die? "

"Uh……"

Liu Xiaofeng said that he can't find it, but he is still a bit not convinced.

Wang Da Zhi, certainly knew that he did not accept the gas, the topic turned, and then said: "Of course, just these are still not enough, but it doesn't matter, we can see the new century after entering the new century?

The choice of various countries in a new generation of transportation machines.

First, let's talk about the An-70, and the An-70 has chosen to the paddle fan, but is precisely because of this?

Therefore, the cruise flight speed of An-70 reached more than 700 kilometers per hour?

Already close to the vortex?

Right? "

"Yes."

This is a fact, Liu Xiaofeng has to nod.

"The A-400M we do in Europe, there is no matter what he is,"

Wang Dazhi then said: "Let's say our neighbor: Dongpu?

After the C-1 transporter?

Now Dongpu people have begun to engage in new generation of transport aircraft C-2, C-2 transport aircraft continues the choice of C-1 in engine, still insisting on using the scroll.

Liu Xiaofei nodded?

But very quickly?

He shook his head: "C-2 is a large transporter.

"Oh ... clearly with the total thrust of up to 532 kW

But the maximum takeoff weight is only 141 tons, and the maximum load is only 37 tons of large transport planes? "

When Wang Dazhi suddenly laughed?

It is the contempt: "The overall performance of this goods is not as good as the -70 and A-400m?

Also, the maximum load can be more than people A-400M.

"..."

Liu Xiaofeng doesn't talk?

Speaking of C-2, it is a shame of the world military transport machine!

This goods use two universal electrical CF6-80 engines, which is the engine used on Boeing 747, single thrust up to 266KN, two engines total thrust or even the four D-30kp on the top of Biel-76 2 The total thrust of the engine is still big?

But the maximum takeoff weight is only 141 tons?

The maximum load is only 37 tons in poor zone?

And under this load?

The voyage is only "amazing"

600 km!

If this still doesn't explain the situation, then there is a living example: the total thrust is 50 tons of the maximum load than the C-2 slightly smaller.

In the case of 40 tons of load, it can fly 4900 km (Il-76TD); the maximum taking weight and C-2 basic US military C-141 transporter, the maximum takeoff weight of 151 tons, the maximum load is 40 tons, but the required total The thrust is only 373.

88KN, the maximum load is also more than 2,000 kilometers.

At the C-2 transport machine, the Characteristics of Dongpu Industry is fully reflected: exquisite to the ultimate component processing capacity and bad to the ultimate system integration, each component is perfect, but these components are integrated together When I became a bunch of people who couldn't bear to perseverance.

"……Ok,"

After half a day, Liu Xiaofeng finally came out: "Just when C-2 is pretending to be a medium-sized transport machine of a large transporter, but in addition to C-2, which medium transport machine uses the turnter?"

"a lot,"

Wang Da Zhi said: "For example, the picture of the old man fried in this time is the picture -330 transport plane, is their solution not a quad vortex? Any-214 transport plane from Il-214 transport plane from Yilin Works Is there any scroll fan engine? "

Figure -330? Il-214? Liu Xiaofeng's mind remembered, since the Soviet Union, the old man made a point of PPT movement every other time, what PPT fighter, PPT aircraft carrier, PPT plane ... At the beginning, you can scare everyone, later Everyone is slowly habit: old hair is like this, light thunder is not rain, who still takes it? But there is a saying, whether it is. - 330 or Ir-214, everyone thinks that these two aircraft feasibility is still very high, Figure -330 can be "shortened An-70 fuselage + Figure -204 Wings + Total Engine "

The version, a large number of mature techniques of Figure -204, even directly moving the wing of Figure-204, and the result is the maximum load of 35 tons, and also has 830 kilometers per hour. The maximum flight speed; Ir-214, which is more close to everyone recognized "classic medium tactical transport machine"

Definition: 20 tons of maximum load.

But even Ir-214, in order to get a higher flight speed, the old hair is also converted to the two more economical oil, which is developing the PD-14 highway than turbo fan engines.

To some extent, Ir -214 and Figure-300 can be seen as a big Maojun industry to explore the next-generation military medium-sized tactical transport machine in the future operations, and in this exploration, they all choose the turntile engine. .
