Chapter 622: All very thoughtful
The engine increases the thrust, and there must be this aspect, but when it comes to the increase in the thrust of the CG-2000 engine, there is a lot of attention to it.
At least now it seems that it is still a troublesome thing to increase the thrust of the CG-2000, Yang Hui clearly knows what technology is used in the CG-2000 engine, and he also knows that with the current technical reserves of the Republic, it will take many efforts to increase the thrust.
The specific situation Yang Hui is not very convenient to say at this time, now is the moment of the MPC-75 passenger aircraft, Yang Hui should fully respect this collection of everyone's hard work.
The test plane in the hangar must have a boarding ladder, and people can enter the plane, and after obtaining consent, they will enter the plane together.
It is also a 3+2 design with five seats per row, but the first feeling after stepping on the plane is that it is more spacious than the McDonnell Douglas series trunk airliner. Of course, when it was advertised to the public, it was a regional airliner, and the reason why it was so spacious was because of the main comfort route.
The reason why this aircraft can give Yang Hui a different feeling of spaciousness is even more jaw-dropping after listening to it, and finally people have to feel that the Germans really have a long-term vision for doing things, even if it is a conscience sewer, oil paper bag, etc., it is far less than what Yang Hui experienced this time.
The German, who doesn't have a long memory, once again spoke half-baked Chinese, and began to show off to Yang Hui: "Our design concept is to make regional airliners have the comfort of mainline airliners, so the cabin altitude of regional airliners makes people can't even walk with their heads up." It's definitely going to be improved, and at the same time we're in the width of the seats. That's also very particular. ”
As he spoke, the guy took out a medium-thickness design manual from his briefcase. Yang Hui clearly saw "MPC-75 Passenger Aircraft - Interior Decoration" on the cover, it seems that this is a design description of the interior layout of the aircraft, and the cabin design scheme of this aircraft should be here.
Seeing the German skillfully flipping through the manual, until he stopped at a book about the cross-section of the fuselage of the world's mainstream airliner, Yang Hui knew why the MPC-75 airliner looked much more spacious than the McDonnell Douglas series aircraft, and it turned out that the cross-section of the aircraft under his feet was even wider than the McDonnell Douglas series.
After sketching some important numbers with a pen, the Germans began to explain: "Our MPC-75 focuses on comfort, and after many studies, it has been concluded that it is calculated according to the ethnographic physique of most of the customers who order this aircraft in Europe and the Middle East. We can't design the maximum cabin width of the McDonnell Douglas 80 series at 3.14 meters, and increasing the maximum cabin width to 3.40 meters is the best cabin width we have calculated. ”
This is true, the local tyrants in the Middle East and the big men in Europe generally have to grow stronger, which is not only reflected in the height, but also in the per capita measurements.
Therefore, between the empty shell A320 and Boeing 737, the old enemies, the 737 passenger aircraft developed by Boeing for historical reasons, followed the maximum width of the 707/727 cabin of 3.54 meters, and the later Airbus was ruthless. When designing, it is also about comfort, which naturally increases the maximum width of the A320 to 3.7 meters.
From the competition between Boeing and Airbus, it can be seen that it is very necessary for the aircraft to be more comfortable, increase the width of the fuselage, and give more space to passengers.
So. The same layout of the MPC-3 aircraft for the 75 + 75 aircraft, at the request of the German designers, fully took into account ergonomics. It is not impossible to increase the width of the cabin to 3.4 meters.
"Increasing to 3.4 meters, it won't increase too much. All we thought about at first was to be more comfortable than the other regional airliners, and by this time it was even more spacious than the McDonnell Douglas 80/90 family seats. This is indeed a bit too wasteful, and an increase in the cross-section of the fuselage means an increase in wind resistance, which will have a bad effect on the fuel consumption of our aircraft. ”
Speaking of which, Yang Hui is also a little optimistic about the maximum width of 3.4 meters, the last super Sukhoi 100 passenger aircraft is designed according to the body shape of the Russians, the cabin width of the 3+2 layout is 3.23 meters, and the cabin width of the CS100 passenger aircraft of Bombardier's frontal impact on the 737 trunk passenger aircraft market is only 3.28 meters.
Counting the Airbus A320 again, the A320 with 6 seats per row is only 0.2 meters more comfortable than Boeing, and the MPC-75 with 5 seats per row is 0.26 meters more than McDonnell Douglas.
Now what Yang Hui wants to say is: how comfortable this guy wants to design this plane, is to turn economy class into business class, and business class into business class
Seeing Yang Hui, the general manager of the Chinese side, he was a little dissatisfied, and the Germans didn't dare to hide it anymore, the reason why the cabin of the aircraft was designed so wide, and even looked a little wide, the reason for this is naturally that everyone fully looked forward to the civil aviation market of the future republic, and believed that the future republic was where the MPC-75 could show its talents.
"Alright! Then I will talk about the reason why we are arranging this way now, through the investigation of the future civil aircraft market, I believe that in the next 30 years, the civil aviation market of the Republic of China will have at least 1,000 medium-haul trunk airliners of the 737 class, such a market is worth our efforts, and the maximum cabin width of 3.4 meters is enough for us to arrange a 3+3 seat layout"
3+3 cockpit layout, Yang Hui is also a little confused at this time, the maximum cabin width of 3.4 meters to make a 3+3 layout, what is this going to do?
When Airbus desperately increased the width of the cabin to 3.7 meters in the 3+3 layout, MPC-75 instead reduced the width to 3.4 meters, and on average, each seat was nearly 5 centimeters narrower than Airbus, which is about the width of a five-cent bill, which is definitely a historical regression!
With such a layout, it is strange that it will not be sprayed to death in the future: "I'm afraid this is not good, we will lead the passenger riding experience to drop to a very low level, which will have a very bad impact on the brand effect of our aircraft, I personally think this is not too appropriate." ”
At this time, there was no need for the Germans to explain, Tang Changhong was the first to rush over and began to explain the reason for doing so.
"The reason why we were able to design such a plan is naturally because we consider the specific national conditions of our country, the average height and measurements of our people are thinner than those of Westerners, which means that we can appropriately narrow the seats, and we have also designed a three-level fare scheme: 2+2/3+2/3+3 three seat layouts are stored on the plane at the same time, and passengers enjoy different spaces at different fares."
Hearing that there can be such a design, Yang Hui doesn't know how to evaluate it for the time being, this seems to be a little feasible, but after careful calculation, it seems that the last person has never heard that airline doing this, and now this is the first person to eat crabs!
Before he could finish this, the Germans came up and added another sentence; "Moreover, we initially think that this scheme is very feasible, the MPC-75 of the 3+3 scheme has been interested in a new European low-cost airline, they believe that the MPC-75 passenger aircraft has a strong economy, low-cost airlines do not need to be comfortable, and the 3+3 layout is even possible in Europe."
Low-cost airlines? How to forget this stubble, this is also a new civil aviation model that will flourish in the future, if you seize a market, it is also an opportunity! (To be continued.) )
