【进博会买买买!明年的发动机先买起来】​
本届进博会上,商飞与GE航空集团先后签订两笔发动机订单,包括88台供44架ARJ21使用的CF34-10A发动机以及19架份LEAP-1C发动机及短舱系统,以上两笔订单将在明年落实。​
看来明年商飞的产能不错,资瓷更多的国产飞机带着更多的人行走天下。​

[Buy, buy, buy at CIIE! Buy next year’s engine first]

At this CIIE, COMAC and GE Aviation Group signed two engine orders, including 88 CF34-10A engines for 44 ARJ21s and 19 LEAP-1C engines and nacelle systems. The above two orders will be implemented next year.

It seems that the production capacity of COMAC will be good next year, and it will support more domestic aircrafts and bring more people to the country.

Pantuo Aviation unveils China's answer to the Lilium Jet
By Loz Blain
4-5 minutes
New render images and details have emerged on our favorite Chinese "I can't believe it's not Lilium" eVTOL air taxi project. The Pantuo Pantala Concept H, out of Shanghai, might look like the Lilium, but it promises to hit faster cruise speeds.

The manta ray shape, the large rear wing with upswept tips, the front canards, the great banks of small electric jets arranged along the wings ... So much of Pantuo's concept is, shall we say, the highest form of flattery, that it might be hard to tell it apart from the beautiful Lilium Jet from Germany.

But there are key differences here. Where Lilium tilts only its propulsion pods, the Pantala is designed to tilt its whole wings. Where Lilium is running 36 tiny electric jets and pushing a small fan philosophy, Pantuo is hedging its bets with just 22 fans, each with a much larger diameter.

The benefit of larger fans, Lilium tells us, is more energy-efficient hover. The drawbacks are tougher scaling, more noise, and less efficient cruise thanks to a bit of extra drag in horizontal flight. So if this thing gets built, perhaps we'll get a chance to verify those claims.

Performance figures won't be immediately comparable, since Pantuo is running a standard five-seat cabin while Lilium has expanded its launch aircraft to a seven-seater. But Lilium promises a 250-plus km (155-plus mile) range at 280 km/h (175 mph), and Pantuo says the Pantala Concept H will match that range, but go faster than 300 km/h (186 mph).

That's about all the detail we've got at this stage. It should be stressed that Lilium is one of the eVTOL world's most advanced projects, with several hundred million dollars in the bank, several hundred employees, and multiple flight tests of multiple prototypes under its belt, to name a few of its achievements. Pantuo has some ripping renders here, but if they've so much as built a remote control prototype, they're not telling anyone at this point.

On the other hand, where EASA and the FAA are pushing an extremely cautious approach to flight testing, the Chinese authorities seem to be letting eHang off the leash early to take the public around in manned flights all over the country.

So perhaps the runway for Pantuo will be somewhat clearer than what Lilium is facing with the European authorities – not that runways will be matters of great concern to the eVTOL sector, although both of these aircraft seem capable of using them where they're available for efficient conventional takeoff and landing.

Why, it quotes at least Yang Zhenmei, a Civil Aviation Administration of China (CAAC) official.
It is 100% accurate translation from Chinese or purposely omitted some words and added their own by reporter?

About CR929 and possibly AC332:

Russia, China continue work on long-range jet — Kremlin

4 Feb, 14:46

MOSCOW, February 4. /TASS/. The coronavirus pandemic created problems for the aircraft industry but Russia and China continue their project for the creation of a wide-body long-range jet, press secretary of the Russian President Dmitry Peskov told reporters on Friday.
The Kremlin’s spokesman highlighted aircraft engineering when listing topics discussed during summit talks in Beijing. "The aircraft industry is the powerhouse of industrial cooperation," Peskov said. "This comprises helicopters and the wide-body long-range passenger jet CR-929," he noted.
"Progress is slower than we would like" in the airliner development project, the Kremlin’s spokesperson said. "The market fell victim to COVID in the case with long-range airplanes; the demand for such aircraft dropped but work continues nevertheless," Peskov said.
Russia and China have been involved in the wide-body long-range aircraft projects for several years. The airplane will have 280 seats and a flight range of 12,000 km in the base version. The total budget for the program was estimated at about $13 bln.

On February 8, the engine of the large-scale fire fighting/water rescue amphibious aircraft AG600-1003 was successfully tested for the first time. During the process, after completing the cold run test, the first test run was completed in the order of No. 1, 2, 3, and 4 engines. The systems of the four engines were in good condition and the parameter indications were normal, laying the foundation for follow-up work. At present, the debugging, inspection and various on-board ground test preparations before the first flight of AG600 aircraft 1003 are progressing steadily.

Quite terrible that they need to redesign the whole plane and produced new prototype only after few years of the maiden flight of previous prototype. Especially, it has already go thru few years of testing only to realized some major structure problem. Plenty of years wasted.

But I guess, this project is at the lowest priority which super computer or top glass wind tunnel are not available for correct accurate data.

That is what prototypes and flight testings are for. Flight testing will reveal whether the prototypes performed up to the expectations of the designer or end users.

Obviously the first prototype did not meet the expectation, thus a revision is needed so that improvement can be made.

Data from flight testing of first prototype will not be wasted, whatever feedback will be store in a database which will be used as reference in future projects.

Not until the extend of rebuild a new prototype and supercede old one. It means clearly a glaring massive design flaw which is quite appalling. But as I say, this is not a top tier project. Resources available is not always the best. Imagine such thing happen to Y-20 project after few prototype build and tested for years, only to realize major design flaw and need to restart again?

Fortunately, Y-20 is a top priority project and massive resources available which ensure the design is almost flaw from start.

The MA700 regional airliner prototype is out at XAC and it has its engines installed.
