[MiG-29SMT]

Obviously you do not care to study C919, A-320 and B737 are powered by Leap engines.

How B-373 is a 1960s design in its core, A-320 a 1980s design and C919 a 2010s design it means C919 is almost 50 years much newer than B-737 and more than 30 years younger than C919

However the range of C919 is lower why?

Simple different engine, different materials, and less efficient aerodynamcis.

C919 uses Leap 1C
B-737 uses Leap 1B
and A-320 uses Leap 1A

fact Leap 1B has lower thrust than Leap 1A but allows B737 have better range than C919
Leap 1A has the highest thrust but allows the longest and greatest range.

Airbus A320 family


Basically the aerodynamics of B737 Max have been refined that even with a older design beats C919, same is A-320

These entities are spread all over China, for example, the flaps, ailerons, wing panels, and centre and outer wing box will be manufactured in Xi'an, China. The fuselage sections will be made in Jiangxi Province.

These parts will all be brought together in Shanghai to complete the end product C919. Most of the air-frame of the C919 makes use of aluminium alloys, with the centre wing box making use of carbon fibre composite materials

Modern Airliners - COMAC C919

✈️The COMAC C919 is designed and built in China and is of a similar layout to the Boeing 737 and Airbus A320, a twin-engined, low-winged, single-aisle aircraft.

while Comac's C919 is empowered by the LEAP-1C (27,980-30,000 pounds). A defining feature is its 18 carbon fiber composite fan blades rotating within a carbon fiber composite fan case.

There are three models of ABC in the LEAP series, which are supplied to Airbus in Europe, Boeing in the United States and COMAC in China. The LEAP-1C exported to China weighed 3,935 kilograms, which was 1,155 kilograms more than the 2,780 kilograms of the B-type. The length increased sharply from 3.14 meters to 4.5 meters, an increase of 1.36 meters. The width and height also increased. The C-type thrust was 12 meters. -13 tons, slightly larger than Type B. It can be seen that the performance of the LEAP-1C is undoubtedly the worst of the three models.

The reason behind this is that CFM has significantly downgraded the LEAP-1C for various purposes, the composite fan case is replaced with a traditional superalloy case, ceramic matrix composite blades and titanium aluminum blades for the high and low pressure turbines. It is also replaced with the conventional superalloy material blades of the previous generation, but in order to make the engine performance look better and have a good selling appearance, we have to increase the air intake, increase the size, increase the number of stages, and ensure that important indicators do not decline, one to two, LEAP -1C has become an engine that is completely different from the A/B types

[MiG-29SMT]

conclusion

A-320 has a lighter engine with more thust, so it has more than 1300km range more with more passengers

C919 with a higher price than B737 Max and heavier engines and lower take off weight it has lees range than a design 50 years older.

Bought on a scam of orders, yes scam CCP owns the same airliners that fly it and COMAC that owns it.

Appeal none

Lower production numbers winner A-320

Not surprising Chinese claim to build the whole statue, while all they did was to provide a TBM and some bronze panels.
Soon that will also go, but Chinese can still claim to build everything just by selling nuts and bolts.

But that was precisely my point Chang. With all these technical prowess China possesses how did an Indian company bag such an order in Mexico ? This obviously means gradually the tide is turning. That's what CCP fears the most .

If these kind of subsidies were made available to say Russia , they'd deliver exactly what the Chinese have been delivering . As I've pointed out many times before to someone like you who's too dense to grasp the larger point , none of what you're producing is innovative .

Like for instance let's see your progress in mfg < 5 nm SMC. You can't do it is coz the US has banned the sales of the ASML EUV Lithography Machines to China. Now since EUV Lithography Machines themselves are too few & far in between , you can't even buy a few to reverse engineer it . Which is why you're lagging behind in this part .

All along like for instance as far as your steel making industry or say your ship building industry goes , you're only duplicating what's been done in the past. The only difference is the scale. It's the scale at which you're doing whatever it is you are doing which is different. That & the massive subsidies you're pouring into these industries like your ship building industry or your HSR industry.

Massive subsidies cannot be supported unless you have an extremely large economy

And you cannot have an extremely large economy that supports massive subsidies unless you have an extremely large industrial base and wealthy people who can consume products from that industrial base

Revenue produced by that consumption allows huge R&D budgets

That is why China is also one of the most innovative countries in the world

China is above Japan at 12th and Hong Kong, China is at 17th.

Please list what exactly has China innovated in the past 4-5 decades ? Is it your HSR ? Japan invented it ? Is it MAGLEV ? Germany invented it . Is it ship building on a giant scale ? The US & UK did it much before anyone else . Japan & RoK are still doing it . Is it your Space Station or Space Program ? The former USSR , now Russia & the US pioneered it .

Is it in the SMC sector ? That wasn't invented in China . Is it in N technology & research ? Once again there are plenty of countries working in that domain which brings me to an important point - how many N reactors have you exported ? Consider Russia & check for the N reactors they've exported including to Bangladesh recently.

Once again I ask you - please list the industries China - the cut copy paste master , has innovated in .

Chinese power grid industry now is silently making huge money abroad now:

Google translate:


The power grid is an old concept, but now it is a new energy and smart grid that requires significant upgrades. Bloomberg New Energy Finance estimates that the cumulative investment in the global power grid from 2022 to 2030 will be $20 trillion, with an annual increase of over 10%. China is clearly ahead, with a far leading power grid scale and stability, and significant technological and cost advantages.

Recently, industry insiders have discovered a trend where many middle-level officials from developing countries come to China to inquire about power equipment. When asked, it was said that the equipment was aging, and like Siemens and other companies had high costs and did not provide good and cheap maintenance. Chinese companies offered a very impressive overall solution, with upgraded equipment technology being even cheaper. In fact, this is not yet the bottom line of China's power industry.

In 2023, the completed investment in power engineering was 967.5 billion yuan, and the investment in the power grid was 527.5 billion yuan, which is 1.5 trillion yuan. Exaggeratedly, the installed capacity of solar power generation is 609.5 million kilowatts, a year-on-year increase of 55%. This is not a year-on-year increase of 55% in newly installed capacity, but a new installation in 2023, which is equal to 55% in all previous years! Wind power is 440 million kilowatts, which is also 20.7%. Thermal power has increased by 4.1%, surpassing all previous years by 4.1% in one year. This is a Chinese style growth, not including year-on-year growth, but cumulative growth.

What does this mean? China has created a stunning gameplay for the stability of the power grid. This is not a new concept, but China is playing on a too large scale. In the figure, the average annual service time of power generation equipment in Chinese Mainland is only 50%, and even many thermal power plants are idle. That is to say, there is a 100% reserve of power generation capacity! Taiwan's reserves are only 20%. The advantage of this is that the stability of the power grid is very strong, and the redundant installation needs to be connected online through power distribution. This is a very ruthless solution to the problem, utilizing extremely strong power infrastructure capabilities to create redundancy and achieve miracles.

6. The global demand for Chinese power equipment will exceed that of communication network equipment. Firstly, let's receive a shocking education to see what the future smart grid is, how powerful new energy electricity is, and to what extent its cost is low. By relying on its power grid engineering capabilities, China can become the world's largest alternative energy exporting country.


I think they are making money silently, since common people don't realize it while they are using it.


Weekly data: grid investment in China more than every other country combined

Grid investment in China more than every other country combined

In 2022, China invested $166bn in its transmission grid, while other countries collectively invested $118bn.

Fine. We've the Chinese Weibo, Baidu, etc. Where's the Chinese ChatGPT Or some version of it? How come with all those AI patents you've filed there's not a single mention of something as innovative as ChatGPT?

See the thing with patents is I can come up with a dust bin where the bin opens from below & file a patent. The organization in charge of handing out patents will merely check to see if there's no previous invention along similar lines. If there isn't any , they'd accept your application & hand over a patent in your name. A patent by itself is no guarantee for the practical application of the product in question or of its commercialization.

What's happening in China, I suspect is the CCP has set targets for all your institutions to file patents & rewards them irrespective of its quality. However institutions which don't file for such patents or fall short of their targets consistently are penalised coz this is how totalitarian regimes operate. The USSR operated in a similar fashion & right till the time of its economic collapse nobody suspected anything.

At least they came out with ground breaking work like development of an alternative defense ecosystem which they sold across the world or their N technology which is again ground breaking stuff or their space program where they definitely innovated being the world's first to launch an artificial satellite or build the world's first space station.

What's China achieved or innovated & I'm repeating this for the millionth time except scale . Hence the ordinary Han slave has started gaming the system & reaping the benefits.
