And for this follow-up, Yang Hui doesn't plan to say anything more, there is really no need to talk about many specific plans for the follow-up MPC-130 project, anyway, there is no one who really needs to know the specific technical route and indicators. Pen, fun, and www.biquge.info

In fact, to take the simplest point, as long as you want, the CG-2000-2 engine plan is close to 9.5 tons of thrust, and the tonnage of large passenger aircraft to be propelled by such data also fluctuates greatly, the CG-2000-2 engine with two engines is expected to be able to reach 19 tons of thrust, and this 19 tons of thrust to say, in fact, even if you use it to push the A320 aircraft with a maximum take-off weight of 75 tons, there is no problem.

Take the McDonnell Douglas 82 aircraft assembled by the Republic in the 80s, this aircraft has also developed a series of aircraft, the largest take-off weight of the series of aircraft is MD-83, with a maximum take-off weight of up to 73 tons, and the high-density passenger layout of this aircraft has also reached the design of 172 passengers, which is definitely the same level as the A-320, However, the engine used in this aircraft is the JT-8D-219, which has a thrust of only 9.3 tons.

What does this mean? It shows that if you are willing, the two CG-2000-2 engines can also push the aircraft to reach the maximum take-off weight of 73 tons, but it is obviously unrealistic to calculate carefully, DM-83 in order to achieve the maximum take-off weight of 73 tons, the thrust-to-weight ratio of the whole aircraft is only about 0.25.

The thrust weight of the MD-83 aircraft is naturally relatively low, which is bound to sacrifice the take-off runway distance of the aircraft, and usually its normal take-off distance reaches 2500 meters, while the same A320 and B737 series due to the high thrust-to-weight ratio of the aircraft, it is about 0.3, so the normal take-off weight of these aircraft is about 2000 meters.

The take-off distance of 500 meters of the gap is not a small problem, the Republic of Civil Aviation requires that the runway length of the passenger aircraft must reach more than 5/3 of the distance required for aircraft take-off and landing, which means that according to the MD-83 such a 0.25 thrust-to-weight ratio design, the take-off distance in 2500 meters of the aircraft directly reaches 4100 meters of runway requirements, and 737 and A320 series aircraft only need to be about 3300 meters in the runway length is enough, and even more relaxed is 3500.

Don't underestimate the 800-meter runway length gap in the middle, which will directly lead to the inability of some second- and third-tier airports in China to take off and land the aircraft, and if the airport can't take off and land the aircraft, then you still play a ball-bearing design! It's impossible to extend the runways of airports across the country in order to take off and land your planes!

Therefore, now according to the thrust-to-weight ratio of 0.3 of the 737 and 320 mainstream narrow-body trunk airliners, the maximum thrust of 19 tons can ensure that the MPC-130 aircraft reaches a take-off weight of 65 tons, and this also needs to take into account that if the CG-2000-2 engine does not reach the specified data of 9.5 tons, if it only reaches the data of 9.2 tons, then some margin should be thrown, and the design requirements between 60-65 tons are tolerable.

The most important point is that the thrust-to-weight ratio of the aircraft in the new era must be higher, so as to ensure that a certain engine has a problem, and the other engine can better ensure flight safety with emergency power, and if the thrust-to-weight ratio of the whole machine is too low, as long as one engine has a problem, the other reserve of emergency power is insufficient will directly take the life of the whole aircraft, which is not so fun.

Anyway, according to the design requirements of the 130-seat aircraft, it is almost in the take-off weight range of 60-65 tons, but since this did not ask why the two CG-2000-2 engines could not be used to design the aircraft more boldly, Yang Hui naturally did not bother to explain too much.

Of course, if the army uses MPC-130 as a special aircraft platform in the future, naturally according to Yang Hui's previous memory, it will be about 2000 years before the launch of anti-submarine, theater early warning aircraft and other aircraft, when the time is almost CG-2000-3 engine development work, at that time can reach 11.5 tons of CG-2000-3 engine in the replacement plan, even if the maximum take-off weight soars to 80 tons, there is no pressure at all.

In the late 90s, the army will launch a high-tech series of aircraft, probably just a few electronic intelligence reconnaissance aircraft, this is not like early warning aircraft and anti-submarine aircraft, electronic reconnaissance aircraft can completely ensure the original aerodynamic shape of the aircraft, at most some blade antennas are more, this is not a problem, and in this way the aerodynamic drag of the aircraft is naturally small, then CG-2000-2 can still meet the needs of use.

........

And to say that this is a plan to hide from the world, Yang Hui hasn't even finished the whole plan, for example, this time, in order to be foolproof, Yang Hui even prepared a series of ecstasy arrays.

Considering that at this time, the new boat 30 and MPC-75 projects of the United Passenger Aircraft Company have been finalized and produced, then the problem comes, if a large passenger aircraft production company does not have one or two projects in development, it is obviously abnormal.

Therefore, this is a series of scripts carefully arranged by Yang Hui, according to the plan of Yang Da's screenwriter, the first thing is to break out a fierce debate within the company about whether to continue to make the MPC-75 into a trunk airliner, or turn back to improve the regional airliner, and of course, in the end, the regional airliner faction will have the upper hand.

Soon, the regional airliner faction will be divided into two factions, one group will continue to change to a fully manned turbo airliner on the basis of the MA30, with a seat capacity of about 60 people, and the other will demand the use of the fuselage of the new boat, and change the turbo engine of the wing crane to the MS-4 engine of the wing crane or tail crane.

The finale of the script is naturally simple, after considering that Embraer already has the EMB-145 series of passenger aircraft, in the end, United Passenger Aircraft Company will choose to take the turbopul engine route of the MA600 series.

And this Yang Da screenwriter's plan is also absolutely reliable, originally after the MA30 passenger and cargo mixed loading, the development of MA600 has long been on the agenda, naturally this belongs to the true and false are mixed in, and this is the highest level of concealment.

As long as the time is up, the big drama arranged by Yang Hui will slowly unfold, and when the time comes, it will directly make those guys abroad confused, and then wait for 97 years to see the two aircraft of the MA600 and MPC-130 together to give the world civil aviation aircraft industry a big surprise.

Although Yang Hui held back these news in his heart and did not say it, the prime minister at this time was already very satisfied, and even happily asked to change the name of the MPC-130 airliner.

"The MPC-75 aircraft was developed by you and Germany in cooperation, so there must be no problem in naming it MPC-75, but this time we secretly developed a new aircraft, so it would be better to change the name? I think we can start with the initial C of our country's English name. There is only one small problem, if the new aircraft is called C-130, it seems to be the same name as the American military transport aircraft, so the number of seats should be changed, can 140 seats work? ”

When it comes to the renaming of the new aircraft, Yang Hui remembers at this time, this secret development of the new aircraft really does not need to be called MPC-130, although the German side knows about this project, and will definitely support the MPC-130 project, but Yang Hui is not willing to announce this project to the Germans, once you announce it to the German side, doesn't it mean that it will be announced directly to European countries?

And now it is best to develop it secretly, and when the time comes, after the public project in 97, see how the German MBB performs, if their performance is not bad, then it is not impossible for them to occupy some shares in the new aircraft, after all, it is still useful to have an ally with enough influence in Europe, lest the German dog jump over the wall and fall directly to Airbus, which will be very troublesome.

But no matter how to position the Germans in the new plane, it is necessary to change the name of the new aircraft now, first of all, the C prefix must be there, although the last C919 is a little delayed, but Yang Hui must admit that the name of the C919 is very good, and now it must be used, but there is also a need to change it.

After thinking about it, it was: "This C prefix must be necessary, and now the giants in the field of trunk civil aircraft are first of all ABD three, and there is just a lack of a C in the middle, so we must definitely put this vacancy on the top." As for the number of 130, the prime minister said that it is okay to increase the number of seats to 140, but we don't have to use the number of passengers to do the number, for example, 737 and 320 do not refer to the number of passengers on the plane, so let's also learn from Airbus and Boeing, and the whole X-X number. ”

Then Yang Hui directly put forward the down-to-earth number of 818, yes, it is 818 instead of 919, although 9 is the pole number of all numbers in the Republic, the meaning is absolutely good, but we are a civil airliner made in the Republic! The project not only needs to make the passenger aircraft manufacturing unit make money, but also to make the civil aviation company make a lot of money, and when it comes to the number of money, can it be less than 8 in our Republic?

Thinking of this, 818 just came out casually: "This is mainly to ask for an auspicious number, and this is also more in line with the preferences of our people, 8 must be indispensable, and 1 means that it is the first civil aviation trunk airliner in our Republic, so it is called C818 airliner!" ”

After carefully recalling the C818 number proposed by Yang Hui, Director Chen of Civil Aviation and the Prime Minister all clapped their hands, this number is simply too easy to use, and it is absolutely down-to-earth. The prime minister, who was quite satisfied with this, patted the armrest of the sofa and nodded slightly in agreement.

"I think this number is very good, our republic's first self-developed large trunk airliner is called C818," C to send "you listen to this homonym is very auspicious!" The project will be officially approved from today, anyway, it is still the same sentence, the country will give you the greatest possible support, and we must make our own competitive machine. ”

Yes, it's the air machine again, how many times is this already the republic's first gas machine? Yang Hui also secretly laughed in his heart about this.

To be able to set the C818 project, it was naturally dark for a while, and the Prime Minister's Secretariat came to remind it, that is, to 'send off the guests': "Then today's conversation is here, you should pay attention to the project when you go back, and quickly set all aspects of the design, the national civil aviation industry and the military are waiting for the aircraft." ”

Don't say that the prime minister is in a hurry, Yang Hui is also quite anxious! In the face of the future explosion of the domestic civil aviation passenger aircraft market, now is the last opportunity for aircraft research and development progress to catch up with the speed of civil aviation development.

In this way, Yang Hui is more determined to C818 strong support, the follow-up research and development of the C818 project must not be put down, the 603 as the company's most powerful large aircraft research and development unit, must also vigorously tilt various resources in the past, this is not only because of the needs of the C818 project, but also take into account the ability to train enough talents.

In order to ensure that the domestic demand for wide-body trunk airliners can be met after 2000, then the 603 Institute will be in addition to the C818 project department, and may need to add another C828 project department, and think that C828 should be a project developed at the same time as the 170-seat C819 project!

Just when Yang Hui was about to turn around and leave, the prime minister over there seemed to suddenly remember something, so Yang Hui hurriedly stopped him again: "Hey, by the way, that Yang Hui is not busy walking first, I have one more thing to tell you when I stay, this is an absolutely good thing!" ”

As soon as I heard that there was a good thing, Yang Hui was absolutely happy, this is already the end of December, and it is almost the time of the New Year, if there is really a good thing that the prime minister needs to say personally, it must be a great thing for AVIC Southwest, go back and announce that the whole company can be happy for a long time, which can not help but be excited!

After apologetic to Director Chen next to him, under the eyes of envy and curiosity, he saw that Director Chen could only leave under the guidance of the prime minister's secretary, while Yang Hui stayed in the office with the prime minister, and the prime minister sitting on the sofa did not mean to stand up.

said more casually: "That Yang Hui, you go and get the document on my desk yourself, it is the one with a pen pressing, you can take it and see for yourself first!" ”

Good guy, are you so awesome? I can go directly to the prime minister's desk to flip through the documents, which is full of trust, and hurriedly walked to the desk, and saw that there was a white cover document pressed under the pen on the desktop, but there was no title on the cover.

Curiously reaching out to remove the file, picking it up and turning the first page was stunned, this... This... This is so unexpected!

At this time, laughter sounded again: "What are you still doing standing there, although this is a good thing, but there is no need to just walk like this!" Take the things and sit down and look at them again, I am mainly thinking about how to arrange for you AVIC Southwest this time, after all, according to the selection rules proposed above, it seems that the number of people you AVIC Southwest can meet the requirements is definitely more than a slap. ”

Just looking at the name of this document, Yang Hui knew why the prime minister said this time, where is this a slap in the face, if it is really in accordance with the above requirements, plus Yang Hui compared with the previous situation, this AVIC Southwest is properly able to report more than double-digit nominations, and all of them are absolute bull-level figures.
