Super Weapon Swap System

Xiong Guo's path is completely different from that of the West.

In the west, the core machine is developed first. After it comes out, it can be used in many aspects and blossom everywhere. As for Xiong Guo, it is a special fund for research and development. What it needs is a hammer in the East and a hammer in the West. Of course, only Xiong Guo has this ability. His country has long been destroyed by high R & D expenses.

To be fair, the performance of this d-436 engine is good and it is a good choice. However, Han also has its own mature power system on yun10 passenger plane. This is the engine specially used for passenger plane by using the core aircraft of turbofan 10 and a large external culvert. This engine is also quite mature now, Has experienced a lot of flight hours.

In fact, this core aircraft is also used on many aircraft in the West. After all, it is actually a mapping imitation product of F110. The core aircraft of F110 is also the core aircraft of the main CFM56 aircraft engine in the West. A core aircraft, equipped with different external culverts, gets different power systems. Therefore, although this engine is very advanced, it is not needed by our side.

If it was that parallel time and space, the state of Han was very eager for this engine. After all, the 20th movement of the state of Han depended on this power system. In order to control the production in its own hands, the state of Han even made a huge investment to acquire 51% of the shares of motor west company and control the company in its own hands.

So now, Vladimir's expectations are doomed to fail. Qin Guan took his brochure and turned to the last page: "tell us about this d-18t engine."

This is the last page. The expectation just now has failed. Vladimir is a little disappointed. He can only continue to introduce to Qin Guan: "this engine was developed for An-124 transport aircraft in those years. Its single thrust is 23.4 tons, with reverse thrust device."

All the contents he introduced were in the brochures. After all, this kind of engine is their biggest. They brought it here mainly to show off their technical strength. At present, they can't find the intention of the Han state to demand this kind of engine. It's useless for the Han state to want this kind of large engine, Unless they have a special military bomber program?

When he thought of this, Qin Guan said, "does this engine have the potential to increase the thrust to 32 tons?"

Thrust increased to 32 tons? Hearing Qin Guan's question, Vladimir was stunned: "what do you want such a big engine for?"

For a mature engine, it is not too difficult to increase the thrust. Anyway, the aircraft engine does not need high mobility. By adding an outer culvert, that is, changing to a larger diameter fan blade, the thrust of the engine can be improved. Western engines, a core engine and different fan blades, get different power, that is.

They naturally have this technology, but it's not necessary.

If the thrust is increased to 32 tons, what kind of aircraft will they develop? I'm afraid it's more advanced than An-225. Do they want to build the world's first flying monster?

What Vladimir expected most was to sell the d-436 engine. As a result, people were not interested. He didn't intend to sell the d-18t, but people put forward a request for improvement?

In this way, the thrust of a modified engine is almost equal to that of four D36 engines.

Now it was Vladimir's turn to question. Looking at his eyes, Qin Guan smiled and said, "it's no secret. We plan to develop a new airliner, code c929. This airliner is a large two channel wide body airliner. Therefore, we need a powerful engine to support it."

Large, dual channel, wide body airliner? The question in Vladimir's eyes is even greater. Even such a dual channel wide body airliner doesn't need such an adverse figure as 32 tons, right? No matter how big it is, can it be bigger than An-124?

Looking at the other side's expression of doubt, Qin Guan patted his head: "Oh, I forgot to tell you that our airliner is a twin engine airliner."

Twin engines? At this time, Vladimir's face became more ugly: "how is this possible? Such long-range airliners are all four engines."

With the continuous development of passenger aircraft and the continuous progress of technology, it has become more and more unified. The long-distance trunk passenger aircraft uses four engines and is hung under the wing. The short-range branch passenger aircraft uses two engines and is hung under the wing. The three release bureaus at the tail have been abandoned and are too unsafe.

So far, there has never been a long-distance trunk airliner with a layout of two engines!

What I've seen now is the Boeing 767. The engine required for this aircraft is only 22 tons. The current d-18t engine is absolutely sufficient. Therefore, the engine power required by Han is so strong that it shows that their aircraft is bigger than the Boeing 767.

"We know that at the beginning of the jet era, the engine power of civil aircraft was not particularly strong. Therefore, civil aircraft with twin engine design generally lacked power, so they could not be used as large trunk aircraft and could only be used as short haul routes or regional aircraft; if you want to fly intercontinental, you must adopt the scheme of four engines Under the circumstances, the power is abundant and strong, but the economy has become a problem again. In the past, there was no way, but now, with the progress of technology, the double engine long-range airliner is bound to become a trend. After all, the cost of two engines is much smaller than that of four. "

Even in terms of thrust, the four existing engines have the same thrust as the two engines to be developed, but the fuel consumption of the four engines is absolutely high. At the same time, the repair and maintenance of the four engines are definitely much more complex than the two engines. Therefore, as long as the dual engine long-range passenger plane that meets the market can be launched, the four engine passenger plane, Will be quickly eliminated.

Although there is no such twin engine aircraft of c929 level, Boeing has begun to act. Their Boeing 777, which uses two engines for intercontinental flight, is also a comfortable dual channel wide body aircraft. If you want to compete with them, you must have the same type of products.

This kind of airliner, with an entry-level thrust of the engine, has to reach 32 tons. Only in this way can it have surging power to promote this kind of aircraft for intercontinental flight.
