readx; Boeing 777 passenger aircraft, this as a Boeing company in the 90s launched a twin-engine long-range wide-body civil airliner, positioning is mainly to fancy the gap left between the market, the project in 90 years, by the Boeing company formally established the research and development work, the ultra-efficient Boeing 777 project department only took five years, to 95 years directly to get the airworthiness certificate of the aircraft, and will also be the first aircraft delivered to the first user United Airlines use.

So as a twin-engine medium and long-range wide-body airliner, the actual opponent of the Boeing 777 passenger aircraft is these two aircraft, shouldering the mission of trying to save the Boeing 767 passenger aircraft in the competition and losing the defeat, the fact is indeed as Boeing expected before, Boeing 777 finalized service after only 17 years, in 2012 to complete a total of 1000 production numbers, this figure in the wide-body passenger aircraft market is already a very remarkable number.

As for the later war, that's pretty much another matter, anyway, the current Boeing is directly playing the 777 against the two models, as for the performance of this aircraft, the order can reflect all the required data.

First of all, when the Boeing 777 aircraft adopts a three-level layout, the number of passengers can reach 300 people, and the high-density layout of the subsequent model reaches 450 seats, and the flight range is between 9000-14000 kilometers to choose on demand, and the minimum range of the aircraft can cover the entire inland of the United States, and then the next level of flight range is across the Atlantic, and finally the longest range model can directly cross the Pacific aircraft, so this is a non-selective medium and long-range intercontinental wide-body airliner.

Therefore, under the comprehensive requirements of this range and passengers, the tonnage of Boeing 777 will naturally soar, and the engine thrust equipped with the aircraft also covers from the smallest 28 tons to the top 50 tons, which can be said to promote the development of the super-large duct ratio turbofan used in the entire civil aviation aircraft to a new level.

For AVIC Southwest at this time, MD-11 does have the potential to be a model that competes with Boeing 777, but when this task indicator is completed, it seems a little embarrassing, the longest range of the entire MD-11 aircraft is only 11000 kilometers, to say that there is no problem to cross the Atlantic, but to say that it will be a little embarrassing when crossing the Pacific Ocean, at least not enough in range.

When the Republic of China at this level procures the MC-11, it is simply a medium-range 9,000-kilometer version of the purchase, which can fly directly to the Midwest cities of the United States after a stop in Hawaii, rather than the type of 777 that can only fly to the cities on the east coast of the United States in one breath, and then transfer to other passenger planes to go directly to major cities in the United States.

Only the MD-11 era is quite embarrassing in terms of range, and now it is even more impossible to go directly to the Boeing 777 level in the hands of AVIC Southwest, at least in Yang Hui's view, this is temporarily unreliable, if it can really develop in the field of wide-body passenger aircraft in the future, then talk about others.

As long as we know that now AVIC Southwest has passed the investigation of major civil aviation companies, there have been the final reliable results, for the design plan proposed by Jinchenko to change the three engines to double engines, in many cases, it will simply be thought that AVIC Southwest will use a larger thrust double engine to ensure the same thrust provided by the previous three engines, but this is very unwise in Yang Hui's view.

If it is really simple and rude to use two 30-ton engines to replace the previous three-engine design, this aircraft will actually become a medium and long-range wide-body passenger aircraft just front of the Boeing 777, you must know that the fuselage section of the MD-11 is actually not small, just 6.2 meters of fuselage diameter compared to the Boeing 777 that 6.19 meters of fuselage diameter is different?

If you really plan to use two 30-ton engines, then I'm sorry, this is exactly the same passenger plane as the Boeing 777-200, AVIC Southwest as a newcomer to go directly to the old civil aviation giants, the final result may be difficult to ensure the success of the counterattack, relatively speaking, Yang Hui is actually more willing to choose the differentiated competition route.

"Our wide-body airliner is definitely a twin-engine, this is certainly not controversial, the problem is that after the company's many considerations, coupled with the relevant suggestions of the airline, our aircraft does not need the MD-11 layout of more than 300 seats, and does not need to do transoceanic flight missions, so this is a passenger aircraft carrying between 240-320 people, and the range should be controlled between 6000-9000 kilometers, and such an aircraft corresponds to the opponent in the market positioning. I guess I don't need to say more, right? ”

Wide-body passenger aircraft not to mention the number of passengers, just the 6000-9000 kilometers of range positioning is a unique existence, even if you search all the civil airliner sequences can only find one opponent, that is, from Airbus's famous work: series of airliners.

A300 passenger aircraft as the foundation of Airbus, not only because of its technical superiority, itself in the positioning of the unique place is also quite a lot, and the reason why A300 can be successful, must also be because this market positioning of the passenger aircraft is objective existence and have related needs, otherwise Airbus would not be able to rely on this project to achieve great success, and subsequently launched an upgraded version of the A310 passenger aircraft.

The successful experience of Airbus is that all manufacturers who are interested in emerging in the field of passenger aircraft must study, and the Antonov Design Bureau has thought about the combination of military and civilian as early as the Soviet Union, so there is a series of wide-body passenger aircraft: An-and-so projects, as for Kinchenko, he must also be very clear about Airbus's set of successful methods.

I picked up the letter on the coffee table quietly, and after rubbing it a few times, I still sighed for a long time: "A300 airliner?" We are positioning the aircraft to the Airbus A300 level is definitely correct, first of all, it is already a product ten years ago, and technically I have not heard that Airbus is going to upgrade these two aircraft, and we are now developing a new passenger aircraft positioned in the same market, which should have a certain opportunity to get the market. ”

The 6000-9000 km range of the wide-body passenger aircraft market is a cut, the passenger aircraft positioned in this market range can generally only fly between regions, and it is very difficult to fly across continents, but fortunately, there are not many aircraft positioned in the same market, in addition to the Airbus A300 is the Boeing 757 narrow-body passenger aircraft, but the 757 passenger capacity is only more than 200 seats, which will not have a big conflict with the wide-body passenger aircraft in the southwest plan of AVIC.

Then there is a 9000-15000 km wide-body passenger aircraft, and that guy is simply a group of demons dancing, first of all, A330 is a generation of hegemon, Boeing's B767 can only be in a safe corner, and the updated Boeing 777 has been put on the market, and Yang Hui also clearly knows that this guy is unstoppable after being put on the market, and then it is completely muddy this market, and then the small arms and legs of AVIC Southwest can not withstand the toss.
