    ARJ21 AC108 returns to Shanghai after route adaptability flight in northeast China


    [​IMG]
    ARJ21 AC108 completed route adaptability flight in northeast China on December 17th, 2017.

    ARJ21-700 AC108 completed route adaptability flight and returned to Shanghai from Harbin on December 17th, 2017. The aircraft took off from Harbin Taiping International Airport at 9:28 a.m. and landed at Shanghai Dachang Airbase successfully at 12:06 after a flight of two hours and 38 minutes.

    It is reported that since flying to Harbin on November 25th, AC108 has taken Harbin Taiping Airport as the main base and conducted route adaptability flight among seven regional airports in Harbin, Heihe, Fuyuan, Jiamusi, Mohe, Wudalianchi and Changbai Mountains in 19 flight days. The aircraft has conducted more than 60 flights and accumulated about 61 flight hours. Among those areas, some have a minimum temperature of lower than -30℃. The adaptability of the aircraft and the manuals in extreme cold condition was fully verified, and simulation verification to the serviceability and the operation supporting capability was conducted. During the route adaptability flight, AC108 has flown to Mohe Airport, the northernmost airport in China and Fuyuan Airport, the easternmost airport in China for the first time.

    This route adaptability flight especially fostered the serviceability of the ARJ21-700 aircraft in cold conditions, created favorable conditions for subsequently putting ARJ21-700 aircraft into route operation in northeast China,and inspected the operation supporting system of Commercial Aircraft Corporation of China, Ltd. (COMAC) for ARJ21-700 aircraft in extreme cold conditions and at regional airports. It is of great significance for putting ARJ21-700 aircraft into operation in Heilongjiang as soon as possible, further expanding the market, and promoting the development of civil aviation industry in northeast China. Chengdu Airlines is scheduled to operate ARJ21-700 aircraft in the regional routes in Heilongjiang in 2018.

    Different sources claim the ARJ21 closely resembles either the McDonnell Douglas MD-80 or the MD-90 which were license-produced in China.[31][32] Chinese factories producing parts for the MD-90 went on to produce the ARJ21 using tooling retained after the end of the MD-80/MD-90 licensed production program..[citation needed] China claims that the ARJ21 is a completely indigenous design[33][34][35] in spite of the fact that production drawings seen for the fuselage during development were simply McDonnell Douglas drawings with the identifying legend overlaid with a Chinese legend.[citation needed] The ARJ21's development did depend heavily on foreign suppliers, including engines and avionics from the United States. The ARJ21 features an all-new supercritical wing having a sweepback of 25 degrees and designed by Ukraine’s Antonov Design Bureau. It is fitted with winglets to improve aerodynamic performance.[36][37][38] Antonov also assisted the project with geometrical determination and integral analysis of the construction strength of ARJ21.[36] Some of China's supercomputers have been used to design parts for ARJ21.[39]

    This is the part where I call BULLSH*T...

    How can production drawings for the fuselage of both aircraft be identical if both the MD80 and the MD90 are significantly longer and heavier than the ARJ21? Both the MD80 and MD90 carry more passengers, have larger wings and have a significantly larger MTOW(ARJ21 95 900 lbs - MD90 166 000 lbs MD80 - 149 000lbs). How can the ARJ21 drawings be a copy of either if they don't even have the same dimensions or specifications?

    It's easy to edit a Wikipedia page and claim all sorts of nonsense, but no citation, source or refference is provided for this particular "insight". Learn to quote reliable source material mate.

    First CJ-1000AX demonstrator destined for the C919 assembled.

    China completes assembly of first high-bypass turbofan engine
    29 DECEMBER, 2017
    SOURCE: FLIGHTGLOBAL.COM BY: STEPHEN TRIMBLE

    A Chinese manufacturer has completed an 18-month assembly process for the first CJ-1000AX demonstrator engine for the Comac C919 airliner, a government ministry says on 29 December.

    The demonstrator will be used to help validate the engine’s advanced technologies, China’s Ministry of Industry and Information Technology (MIIT) says in a news release.

    China plans to build 24 more CJ-1000A prototype engines to support an airworthiness certification campaign, with entry into service targeted after 2021.

    The news release reveals two new dimensions of the indigenous Chinese rival to the CFM International Leap-1C to power the C919.

    The CJ-1000AX has a diameter of 1.95m (76.8in) and a length of 3.29m (10.7ft), the release says. That compares to the 1.98m diameter and 3.32m length of the Leap-1C. The shorter length of the CJ-1000AX is likely explained by a design that compared to the Leap-1C uses one fewer stage of rotating blades in the low pressure turbine.

    In many other respects, the Chinese manufacturer – AECC Commercial Aircraft Engine (ACAE) – and CFM use a similar configuration, with a two-spool layout, featuring a one-stage fan, three-stage booster, 10-stage high-pressure compressor and two-stage high-pressure turbine. The CJ-1000AX uses six stages in the low pressure turbine, compared to seven in the Leap-1C.

    But the engine designs also reveal sharp differences in the use of advanced technologies. ACAE has not selected a fan drive gear system for the CJ-1000A, but it does use Rolls-Royce-style hollow-titanium, wide-chord fan blades, according to the MIIT release. By contrast, CFM uses an equal number of 18 blades, but they are made of carbonfibre.

    The MIIT release also discloses that ACAE is 3D printing the fuel nozzles for the CJ-1000AX’s single-annular combustor.

    In 2012, a Texas-based consultancy named Lucintel published a turbofan market forecast showing plans by China to develop three versions of the CJ-1000. A roughly 25,000lb-thrust CJ-1000AX demonstrator would come first, followed by a 28,000lb-thrust “A” version for production and finally a roughly 27,000lb-thrust “B” model for extended range aircraft.

    So let me get this straight... your solution to fractured compressor blades is to drill holes in it? :rofl:

    Dude, the whole point is to make it more efficient, not less efficient. You are supposed to be designing super hard resistant tips so they don't break, not drilling holes into a poorly made blade.

    I would marvel at how your knowledge in aero-engine design and manufacturing rivals that of actual engineers or point out that perforated engine blades are hardly exclusive to Chinese engines,

    But I know you're just trolling and I don't have the time or patience for ignorant arguments from you today. Have a pleasant day my good man.

    C919 Jumbo aircraft is China's first fully based on the international advanced Airworthiness standards and the mainstream market standards independent research and development of a single-channel trunk plane. May 5, 2017, C919 first passenger plane flew successfully in Shanghai. The same year December 17, C919 second passenger plane in Shanghai "soaring".

    Wu Guanghui introduced that, so far, the two planes have flown in total 23 sorties.

    "I haven't been flying in a while, and a lot of people have asked me if it was an accident, but we're quite normal," Wu Guanghui said.

    He also revealed that next year there are three aircraft to be the maiden flight, the entire airworthiness forensics test total of 6 aircraft involved.

    On the airworthiness review, Wu Guanghui said C919 will conduct joint audits through CAAC and the European Airworthiness authority to ensure that the aircraft achieves the best and safest status. It is reported that the China Civil Aviation Administration (CAAC) in 2010 accepted the C919 Model certificate application. 2016, the European Aviation Safety Agency (EASA) accepted the C919 model certificate application.

    Wu Guanghui said that China Commercial Aircraft Co., Ltd. is fully committed to speeding up the development of C919, the current C919 international and domestic users up to 28, 815 orders, "We C919 is a market-popular aircraft." ”

    In addition, China Commercial Aircraft Co., Ltd. also plans to deliver 15 ARJ21 new regional aircraft this year, in addition, the Sino-Russian Joint long-range wide-body passenger aircraft CR929 is also under development. Finish)

    China's C919 receives 30 new orders
    Editor: zhenglimin 丨Xinhua

    02-26-2018 18:28 BJT

    BEIJING, Feb. 26 (Xinhua) -- China's C919 large passenger aircraft has received 30 new orders from a domestic leasing company, taking total orders to 815.

    [​IMG]

    Commercial Aircraft Corporation of China (COMAC) signed a purchase agreement with China Huarong Financial Leasing Co., Ltd. for 30 C919 and 20 ARJ21 on Monday in Beijing.

    To date, C919 has gained 815 orders from 28 customers home and abroad. ARJ21 orders have hit 453 from 21 customers.

    China Huarong Financial Leasing Co., Ltd is a subsidiary of China Huarong Asset Management Co., Ltd, one of the country's largest asset management companies.

    "We expect to establish a comprehensive cooperative relationship with COMAC," said Lai Xiaomin, chairman of China Huarong Asset Management Co., Ltd.

    COMAC's ARJ21, a regional aircraft with 90 economy seats, was delivered to Chengdu Airlines in late 2015. To date, it has carried 49,000 passengers, the company said.

    The C919 is in the test flight phase following a successful maiden flight on May 5, 2017. The narrow-body jumbo was developed to rival the updated Airbus A320 and the new Boeing B737.

    COMAC has also set up a joint venture with a Russian state company to build wide-body passenger jet CR929. It said the joint development is now in full swinging.

    Yes, its the same plane that you and @Armand2REP want to crash. You had better fly in an Indian airliner then. Oh wait...

    I'd rather not rehash you fantasies. But...

    How does a plane that's flown 17 times last year since May 2017 "average 9 flights a month"? Basic maths puts that average at roughly 2 flights a month as at December 2017.

    Last quarter of 2017 was average of 9 flights per month on one airframe. 1st quarter of 2017 with two airframes and not a single test flight. Something went very bad.
