Engines like the RB-211 are now fully able to meet the needs of short- and medium-range wide-body airliners, and the engine itself also uses a lot of new technologies developed by Rolls-Royce in the 90s, a large part of which is even the technology of the Ruida series of engines and then taken back to the RB-211, so it is definitely not backward in technology. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

With the RB-211 engine to sit the real head, so as to ensure that the short-range wide-body passenger aircraft has an engine with excellent performance, or the D-18T series engine that technical level, after all, it is not very suitable for the use of wide-body passenger aircraft in the southwest of AVIC, to insist on using only D-18TM may directly affect the sales of the aircraft, so the choice of a mature engine as the power system is a wise and calm choice.

As for why Yang Hui still wants to cooperate with the Ukrainian side when he knows that the D-18TM engine is not suitable, the reason is, of course, more considering that if only one engine is planned to be installed, the aircraft is likely to be stuck in the power system, and there is no other engine to counterbalance, and Rolls-Royce will not have to rush to the sky in the future.

To say that the biggest role of the D-18TM engine is not actually to put it on the plane and sell it on a large scale, it is more just to play the role of a spare tire, and let Rolls-Royce know all the time: even if there is no Royce butcher, the United Airliner Company will not eat hairy pigs. This can be regarded as a modern remake of razing, and in general, it is still thanks to Li paste.

Yang Hui proposed the D-18TM engine to use, which was also the result of taking into account the influence of all aspects, Kinchenko did not understand Yang Hui's true thoughts at this time, but no matter what, the D-18TM also had a temporary way out.

It is also full of smiles: "To use the D-18TM engine, it can indeed ensure our wide-body airliner research and development work, but as a hugely expensive wide-body airliner, it is certainly impossible to use only one engine, presumably the company should have other alternative engines, right?" ”

The so-called other options,It must refer to other power systems other than D-18TM,Under normal circumstances, Yang Hui will directly say the RB-211 option at this time,But at this time, it is not normal,Compared with the RB-211 engine,Yang Hui is more willing to talk about the republic's own super-thrust and large bypass than civilian turbofan engine。

However, before that, Yang Hui needs to calculate the time node well, on the one hand, the development of ultra-large thrust turbofan will definitely involve technical problems, on the other hand, it is also necessary to consider how to get the order and recognition of the first user, about how to enter the market in a sense, it is even more important.

As I said before, twin-engine wide-body passenger aircraft have extremely high requirements for the reliability of the engine, under normal circumstances, as long as one of the three giants is willing to provide the engine, I am afraid that civil aviation companies will not choose to develop a new engine, so in some sensitive aspects, Yang Hui first chose to give up, but even he himself felt that he could not be too hasty, and the development of the engine used in civil airliners should be gradual and gradual.

The whole so-called gradual development, which has to think of other ways to put the new engine of the United Aero Engine Company into operation, and civil airliners in addition to the passenger transport that is more sensitive to safety requirements, in fact, an aircraft can also be changed to cargo use, or simply changed to a variety of military special aircraft, such as: tankers, early warning aircraft, and so on are possible.

For the above non-passenger wide-body models, they can be assured and bold when choosing the engine, first from the point of view of the time node, it can be expected that at least until about 2005 will be able to officially put the wide-body passenger aircraft into service, and then slowly develop the improved model of the aircraft: cargo type.

As long as the engine is finalized in 2010 and installed on the cargo plane for testing, it will be able to make the cargo type enter large-scale service around 2012.

After all, that guy happens to be between 6000-9000 range, which can be used to meet all domestic routes, whether you are from Sanya to Xinzhuang, or southern Yunnan to Heihuanjiang, you can fly in one breath across the country, and the double-engine passenger plane is originally low in fuel consumption, and then rely on its own cabin is large enough, it may wait until a certain wind to buy a cargo plane, it is no longer as simple as buying a narrow-body passenger plane.

As long as the cargo aircraft orders engaged in the civil aviation cargo business after 2010 can be won, then you can choose to install the republic's own engine, and wait until the engine is installed and used in the cargo passenger aircraft for a few years, as long as there are no major problems, the engine safety, reliability, and even other problems such as fuel consumption can be easily solved.

For example, when the army is developing a new generation of early warning aircraft, it is no problem to say that it is okay to use a twin-engine wide-body passenger aircraft, or a four-engine domestic C-320 transport aircraft as a platform.

Then not only the AWACS platform, as long as there is that will, you can even replace the aircraft with a domestic engine with greater thrust, just follow the path of the American KC-10 air tanker, and a super nurse will be refined in this way, and the air tanker of the Republic will completely catch up with the world's most advanced level.

When you want to use a wide-body passenger aircraft for military use, needless to say, you can only use the engine developed by the country itself, so no matter from which point of view, China must have its own turbofan engine with large thrust and large bypass ratio.

And this engine is not even a level with RB-211, after Yang Hui combined with the analysis of the development of civil airliners in the future, relative to RB-211, which covers the 18-27 tons of thrust range of the engine, it will actually not continue to be popular in the future, and it can really be used as the mainstream super-large thrust turbofan engine in the future, it must get more than 28 tons of thrust, that is to say, it must be a level larger than RB-211.

In the future, after accumulating experience through short- and medium-range wide-body passenger aircraft, it will really compete head-on with Airbus and Boeing, and lay the foundation of ABC's three-legged momentum, which must be the era of Boeing B787 and Airbus A350, at that time, the twin-engine wide-body passenger aircraft had to soar to 16,000km in the range, and that was the world-class super melee.

At that time, the wide-body passenger aircraft in the southwest of AVIC must be skinned to the original 56 meters long of the MD-11, and the flight range of the aircraft must also be changed from short and medium-range to intercontinental long-range intercontinental passenger aircraft, and there must be a new upgrade in terms of fuel carrying and maximum take-off weight, and the maximum take-off weight of about 240-270 tons must be met.

For the engine thrust required by the passenger aircraft with a maximum take-off weight of 240 tons, it is really as said before, it must use a large turbofan with a thrust of 35 tons, and the so-called 35-ton high-thrust turbofan is definitely a super project, once it is completed, it is a weapon of the country. also

Only after the Republic has developed the corresponding engine on its own can it be said that the United Aero Engine Company will be able to communicate and negotiate with the three giants of Aviation Development on an equal footing. (To be continued.) )
