SHANGHAI—COMAC is looking at supersonic speed and unconventional configurations among the technologies for aircraft to follow the wide-body airliner it will develop with United Aircraft Corporation (UAC).

The two companies may register a joint company for the wide-body aircraft program this month, COMAC Vice President Shi Jianzhong said, referring to the event that would mark the launch of full-scale development. He spoke at a civil aviation conference in Shanghai organized by Galleon.

For the future, COMAC is investigating new propulsion systems; new structures; unconventional configurations; supersonic speed; and new energy sources, Shi said. It is also considering the use of Big Data, and a concept called the “intelligent aircraft.” The work is going on in consultation with suppliers, Shi said, neither giving details nor saying when an aircraft incorporating the technologies may appear.

COMAC and UAC said in November that development of the wide-body aircraft would take 10 years. Since the program is now supposed to be fully launched this year, the schedule implies first delivery in 2027. However, program managers have discussed a date range of 2025–28.

Slippage is appearing even before the beginning of full-scale development, however. In November, COMAC and UAC expected to set up their joint company in 2016, or in the first quarter of 2017. They still have not done so. “In May, we may sign an agreement with the Russian side and hold the ceremony for registering the joint company in Shanghai,” Shi said.

The C919 flight was planned for February, Shi told the conference. He was evidently referring to the latest schedule, because when the program launched in 2008, the first prototype was supposed to fly in 2014. When the day of the first flight finally arrived, “Everyone will have noticed that the weather was not particularly good, but the flight was quite perfect,” the manager said.

Outwardly confident at the time of its establishment to create the C919 in 2008, COMAC has recently tended to emphasize the challenges that it has faced.

Among the difficulties at the time of establishment, “Staffing was a difficulty,” Shi said. “At the time, there were few people working on commercial aircraft in China. Including administrative staff members, we had only 3,000 people. But now we have passed 10,000, including, of course, some foreigners, people we have trained and university students in many fields—graduate students, doctoral students, and so on,” Shi said.

COMAC was formed from several AVIC units, particularly those that were making the ARJ21 regional jet, which became a COMAC product. AVIC builds the structures of the ARJ21 and C919.

Great success. Big day for all Chinese. Many congratulations to all.

Baosteel switches gears, lands big deal from COMAC
By MENG FANBIN in Beijing and WU YIYAO in Shanghai | China Daily | Updated: 2017-05-10


On Friday, when COMAC's C919, China's first homebuilt passenger plane, took off from, and then landed safely at, Shanghai Pudong International Airport, it not only completed its first test flight successfully but marked a major milestone for the Shanghai-based Baosteel Special Steel Co Ltd.

For, the C919 used landing gear made by Baosteel Special Steel, also known as Baosteel, which is now the first Chinese supplier of such hardware for passenger jets.

"It is the first time that the 300M steel researched and produced by the company is used in the production of landing gear in China and it shows we have made a breakthrough in this sector," said Zhao Suwu, a senior engineer from Baosteel Special Steel.​

"Baosteel Special Steel's landing gear improves greatly China's steel and high-end special steel metallurgy expertise, which has been recognized globally," said Yang Zhiyong, director of the Special Steel Institute,which is part of the Iron and Steel Research Institute.​

It also marks the first global foray of Chinese makers of high-end special steel and high-end aviation parts, Yang said.

Landing gear, being the largest and heaviest steel part of an aircraft, is critical as the whole weight of a plane rests on it and it should be able to withstand strong impact during landing.

Special steel that is used to make landing gear is difficult to produce. Standards are exacting to ensure the hardware's stability, impact resistance and fatigue resistance, Zhao said.

The amount of homemade alloy used in the C919 is not much because Chinese special steel and alloy makers' research, quality control and cost control processes are not as mature as foreign competitors', according to a report in China Metallurgical News.

"Steel accounts for only about 10 percent of the whole weight of the jet, so as to reduce weight and save energy. Most of the materials in the plane are alloys and nonmetals," said Yang.​

Baosteel Special Steel and Fushun Special Steel Shares Co Ltd, in Liaoning province, are the only two certified domestic steel suppliers for jumbo aircraft, compared with four foreign players, including India's Tata Group and US major Carpenter Technology Corp.

However, COMAC's decision to use Baosteel Special Steel's landing gear is bound to help develop China's aviation steel segment.

After 60 trials for industrial-scale production, the company has developed a homegrown process spanning the whole chain for special steel manufacturing technology for the C919, said Zhao. The research and development process lasted more than seven years, she said.

Over the years, China's steel makers had been blocked from becoming qualified suppliers to aircraft makers and hence have been eager for their big break in the aviation steel segment.

HBIS Group Co Ltd provides high-end steel materials for the die forging machine that makes the C919 landing gear. COMAC's component platform uses modular design,which means each supplier can be replaced.

The China Metallurgical News report quoted a COMAC expert: "It's only a matter of time before China's domestic materials replace the imported ones, given the improvement in the quality of Chinese suppliers' products and their cost control."

AirAsia’s Fernandes says it’d be `foolish’ not to consider C919

tonyfernandes18aug15.ashx



SINGAPORE: AirAsia Bhd, the low-cost carrier that flies only Airbus SE planes, would consider using newly developed aircraft such as the Chinese-made C919 as the airline expands its fleet and destinations.

“I think as an airline you have to look at everything,” AirAsia Group chief executive officer Tan Sri Tony Fernandes said in a Bloomberg Television interview, when asked whether the carrier would consider the C919. “We will be foolish not to look at new planes.”

Willie Walsh, chief executive officer of IAG SA, the owner of British Airways, has said the company would consider the Chinese-made aircraft. Commercial Aircraft Corp. of China Ltd., the planemaker, has commitments from 23 customers for about 570 of the C919, which took its maiden flight on May 5.

AirAsia made a key advancement in its goal to create a pan-Asian low-cost airline this month, when he announced a partnership with China’s Everbright group to create a budget airline in the country.

Fernandes is predicting the rest of 2017 will be better than last year, after the company posting a 30% drop in first-quarter net income, saying the competitive environment is improving.

“We are seeing much better load and yields in the second, third and fourth quarter,” Fernandes said in the interview with Haslinda Amin.

“So, 2016 was a record year. We think 2017 will be better than 2016.”

Net income in the first three months of 2017 fell to RM615.8mil from RM877.8mil a year earlier, AirAsia reported Thursday. The carrier also said it plans to add 29 planes for a total of 201 by the end of this year.

The Chinese venture will be based in Zhengzhou, the capital of central Henan province. While Fernandes declined to identify specific routes for the Chinese venture, he said the carrier would focus on markets where it can grow and would “never go to Shanghai, Beijing.”

“We don’t want to disrupt existing markets,” the executive said. “We want to create new markets and build new business. That’s what AirAsia has been good at.” - Bloomberg

Its great achievement for both Russia and China for MC21 and C919. In a friendly comparison which one fares better from technology, business and passenger prospective? For example MC21 taken number of steps in using composite wing, increase fuel efficiency, wide isle for faster boarding etc.

What are C919 exceptional features?

Also, there was a program both Russia and China to jointly develop bigger class, long range aircraft; anyone knows what is the status?

AFAIK for C919, the body was locally manufactured and we have used as much composite material as we could

This graphic described which parts are to be done locally and which to be procured from overseas:

You can see there a lot of imports, but this is also true for most other commercial jet models from Boeing to Airbus et al and we are going to scale down the % of imports over time As a relatively newbie in commerical airliner production, the steps taken by COMAC is necessary. The benefits which bring about with this production strategy are multifolds.

We have these promises from the following supplier:

For the engines. We are using CFM LEAP-1C which is produced by a Safran (France)/GE(US) JV

The quality of the engine is described in the following article:

CFM LEAP-1C-powered COMAC C919 completes successful maiden flight
  • Another step closer to entry into service
SHANGHAI, China — 5 May 2017 — The first COMAC C919, powered by CFM International’s advanced LEAP-1C integrated propulsion system, successfully completed a 79- minute first flight, marking the launch of the certification flight test program for the 150-passenger aircraft. The engines performed flawlessly.

“This is a great day for all of us,” said He Dongfeng, president of COMAC. “We are very happy with the LEAP-1C engine and have been pleased to work with CFM on this program. The engines performed beautifully during today’s flight and we believe they will bring our customers the levels of fuel efficiency and reliability they will require in their daily operations.”

“This is an epic moment,” said Gaël Méheust, president and CEO of CFM International. “On behalf of everyone at CFM, I expend our warmest congratulations to everyone at COMAC on achieving this great milestone. Our relationship with the aviation industry in China goes back more than 30 years and it is an honor to be part of the COMAC team as it launches the next exciting era in the country’s aviation history.”

To date, more than 5,000 CFM engines have been ordered/committed in China, including orders for more than 1,000 LEAP-1C integrated propulsion systems. The LEAP-1C integrated propulsion system was simultaneously awarded Type Certificates by both the European Aviation Safety Agency (EASA) and the U.S. Federal Aviation Administration (FAA) in December 2016. Since then, COMAC has performed a series of ground tests, including low-speed and high-speed taxi tests leading up to today’s flight.

The LEAP engine was officially launched in December 2009 when COMAC selected the LEAP-1C as the sole Western powerplant for its 150-passenger C919 airplane. The engine incorporates a unique fully-integrated propulsion system (IPS), which includes the engine, nacelle, and thrust reverser. The IPS, along with the pylon developed by COMAC, were designed in conjunction with each other, resulting in improved aerodynamics, lower weight, and easier maintenance.

The LEAP-1C’s composite O-Duct thrust reverser was developed by Nexcelle*, with its unique one-piece configuration contributing to a reduced overall structural weight and larger acoustic treatment surface.

In addition to the IPS, the LEAP-1C engine features some of the industry’s most advanced technologies, including 3-D woven carbon fiber composite fan blades and fan case; a unique debris rejection system; 4th generation three dimensional aerodynamic designs; the Twin-Annular, Pre-Swirl (TAPS) combustor featuring additively manufactured fuel nozzles; ceramics matrix composite shrouds in the high-pressure turbine; and titanium aluminide (Ti-Al) blades in the low-pressure turbine.

The LEAP engine entered commercial service in August 2016 and is currently in operation with more than 10 airlines worldwide. The engines are providing operators with a 15 percent improvement in fuel efficiency and CO2 emissions compared to today’s best CFM engine, along with dramatic reductions in engine noise and exhaust gaseous emissions. All this technology is bringing with it CFM’s legendary reliability and low maintenance costs.

About CFM International

The LEAP engine is a product of CFM International, a 50/50 joint company between GE and Safran Aircraft Engines. This engine has experienced the fastest order ramp up in commercial aviation history, with the company receiving orders and commitments for a total of more than 12,230 engines across all three models.

China has a new jetliner—here's what that means
How the C919 airliner fits into China's larger aviation future.

Chinese Internet, via Andreas Rupprecht


On May 5, the COMAC C919 jetliner made its first flight. It's a major triumph for China, who has invested a lot to build up its civilian aerospace industry.

Let's talk about the plane: The twin-engined, narrow-body C919 has a maximum takeoff weight of 77 tons, a range of about 2,500 miles (about 3,400 miles for the extended-range version), and space for 160 passengers. Its contemporaries in the world of twin-engine single-aisle crafts are the Boeing 737 and Airbus A320, so the market is projected to make up the majority value of $1 trillion, with an estimated 6,000 airliner sales in China over the next two decades. China's also taken a lead ahead of Russia's United Aircraft Corporation (UAC), whose similar MC-21 jetliner has yet to make its first flight.

Smartphones of the Skies
The C919 uses LEAP-1C engines made by the French-American joint venture CFM. Longshi


Today, aircraft makers like Airbus, Boeing, and COMAC are similar to smartphone makers in that they buy and integrate highly specific, third-party manufactured equipment into the end product, with much of the profit margins coming from maintenance, service, and upgrade contracts. Just like its Airbus and Boeing counterparts, the C919 relies on outside suppliers—often western ones—to supply critical systems like the LEAP-1 engines, avionics, and the landing gear. China hopes, though, that Chinese suppliers will start supplying the C919 and other jetliners with parts. Beijing hopes that the C919 and any eventual domestic supply chain will boost efforts to establish a domestic supply and research base.

After a 90-minute flight, the C919 prototype returned to its home airfield in Shanghai. With already 500 (mostly domestic) preorders, China hopes that the C919 will also have significant export prospects. Andreas Rupprecht




Currently, the vast majority of the C919's 500-plus preorders have come from Chinese airlines. In April 2017, European Aviation Safety Association (EASA) agreed to help validate Chinese aviation authorities' certifying process of the C919's airworthiness. An EASA endorsement of the C919's airworthiness would increase its export prospects, especially in Asia and the Middle East. After EASA certification, the C919 could hope to win approval from the FAA sometime in the mid 2020s.

y-10.jpg

Y-10
Designed by the Shanghai Aircraft Research Institute, the Y-10 first flew in 1980, but its outdated technology meant that only three were built. It was retired in 1984, four years after its first flight. Hush Kit



Despite claims elsewhere, the C919 is not China's first large jetliner. The Shanghai Y-10 was a four-engine narrow-body airliner (like the Boeing 707 and 720) that carried up to 178 passengers and had a 110-ton maximum takeoff weight. It first flew in 1980, after years of development, but retired in after only three aircraft were built, due to its outdated technology (it had to use Pratt & Whitney JT3D-3B engines) and fuel inefficiency. Its autarkist connections to Red Guard ideology did not help it politically, either. Its chief designer, Wu Xingshi, would also design the ARJ-21, the next Chinese jetliner.

comac_arj21-700_xiangfeng_-_jordan.jpg

ARJ-21
The ARJ-21, which first flew in 2006, is a regional passenger jet that marked the revival of China's ambitions in the jetliner business. Jordan



The ARJ-21, China's first jetliner since the Y-10, would have different problems. As COMAC's first jetliner, the ARJ-21 is a 98-passenger, 47-ton twin-engine jet in the same class as the Bombardier CRJ700 and Embrarer E Jets. However, the ARJ-21 suffered the indignity of an eight-year gap from its first flight in 2008 to entering service with launch customer Chengdu Airlines in 2016.

This delay can be attributed to COMAC's inexperience in obtain a flight worthiness certificate from Chinese authorities and quality control issues on the prototype. Presumably, EASA's willingness to sign onto the C919's certification process suggests that COMAC has learned from the ARJ-21 experience.



c929.jpg

"C929"

The Sino-Russian jumbo jet, tentatively designated C929, will be assembled in Shanghai with a service entry date of 2025. COMAC and UAC are already working on establishing the preliminary design, with a first flight in 2022-23. Research and development is estimated to be $20 billion.
Chinese Internet


If the C919 is a success in domestic and export markets, it would be a huge step forward for the Chinese aerospace industry. COMAC also has big plans for building jumbo jets. In 2016, COMAC and UAC signed an agreement to co-develop a 250-seat, 290-ton, 7,450-mile-range plane tentatively designated the C929. Its first flight is targeted for 2022, and it will potentially enter into service by 2025. The C929's construction will use large percentages of composite and titanium parts in order to reduce its weight, thus boosting payload, range, and fuel efficiency to compete with the Boeing 787 and Airbus A350. Like the C919 (and MC-21 for the matter), the C929 will likely use foreign parts, especially in the engines.

The C919 still faces large challenges, even with its successful flight. Its test flight and targeted entry to service dates have so far slipped from 2014 and 2016 to 2017 and 2020. But to be fair, almost all ambitious aerospace projects (including the Boeing 787 and Airbus A380) suffered delays, missing the initial service dates by years.




Dont be discouraged by the mishaps to Superjet cause we have had our big teething problems as described above in the now defunct Y-10 project and (not in the above report) the incidents of our Xian MA-60 turbopop. I wish our Russian friends the best with their Superjets corrections, and their going well with their MC-21. Also eagerly looking forward to a cordial and productive C929 cooperation

If the C919 is a success in domestic and export markets, it would be a huge step forward for the Chinese aerospace industry. COMAC also has big plans for building jumbo jets. In 2016, COMAC and UAC signed an agreement to co-develop a 250-seat, 290-ton, 7,450-mile-range plane tentatively designated the C929. Its first flight is targeted for 2022, and it will potentially enter into service by 2025.

But to be fair, almost all ambitious aerospace projects (including the Boeing 787 and Airbus A380) suffered delays, missing the initial service dates by years.

Dont be discouraged by the mishaps to Superjet cause we have had our big teething problems as described above in the now defunct Y-10 project and (not in the above report) the incidents of our Xian MA-60 turbopop. I wish our Russian friends the best with their Superjets corrections, and their going well with their MC-21. Also eagerly looking forward to a cordial and productive C929 cooperation

Thanks much for sharing the info.Russia has long experience in commercial aircraft, engine and composite tech. I am sure combined Russian and Chinese know how will be reflected on C929. One more sanction tool can be taken off the table.
 
.
Also, there was a program both Russia and China to jointly develop bigger class, long range aircraft; anyone knows what is the status?
Latest news, May, 23, are that joint venture is created.

Best wishes!

What happened to the Superjets which were EASA certified? The problem which disclosed as "metal fatigue" was looking rather serious, wasn't it?

When will it return to service? and good luck with that.
They are in service. Flightradar24 reaffirms. Such "problems" are quite usual thing for newly developed machines.

MC-21 composite wings and other composite parts are made by FACC, an austrian composite specialist.
do you know FACC is owned by AVIC the parent company that make C919? lol

Can you or someone else here explain me the details about parts in C919 made of composite materials and the technology used in the production, please?

Orders for China's C919 jumbo jet reach 600
Xinhua | Updated: 2017-06-13

SHANGHAI - Orders for China's first homegrown large passenger jet, the C919, reached 600 aircraft on Tuesday as a new customer signed to book 30 of the jets.

China Everbright Financial Leasing Co Ltd on Tuesday placed the order with the Commercial Aircraft Corporation of China (COMAC), the Shanghai-based manufacturer of the C919.

Zhang Jinliang, president of China Everbright Bank, which has a 90-percent stake in Everbright Financial Leasing, said the bank will continue cooperation with COMAC in research and development as well as marketing.

So far, a total of 24 foreign and domestic customers, including China's national carrier Air China, have placed orders for the aircraft.

C919 completed its maiden test flight in May, making China the fourth jumbo jet producer after the United States, Western Europe and Russia.

With a standard range of 4,075 kilometers, the China-made jet is comparable to updated Airbus 320 and Boeing's new generation 737 planes, signaling the country's entry into the global aviation market.

My friend,

You know we all love J10 to J20 and everything inbetween.

However, I must say that biggest nightmare for the West is Chinese Civil Aviation industury!

If you look deeply then the entire ecology of Civil Aviation in China is becoming Chinese.

The article you posted is just one example of this. This plane is one of those Transformative Leaps in development that turns a country into truly industrialised Giant.

The Dragon is just unfolding its wings... can hardly wait the Great Dragon to Soar.

Patience is a Virtue. I must exercise Virtue!

Regards,

SPF
