Plan For China C919 Airliner Hits A Snag


Call it a case of being let down by one’s older brother: New delays in the certification of the Comac ARJ21 regional jet could force the development of the C919 mainline commercial aircraft to be prolonged.

The FAA is insisting its shadow certification effort on the ARJ21 be completed before the agency begins work on the C919. But the C919 is already near the point at which a certification agency needs to be brought in; if the project advances much further without the FAA’s involvement, the U.S. regulator may decide it can never become involved.

Moreover, Comac has shifted scarce engineers to help sort out the ARJ21’s problems at a time when the C919 is already running a few months late. Since FAA endorsement of the C919’s Chinese certification is indispensable to the international sales prospects of the 156-seat, six-abreast aircraft, the brewing crisis again raises questions about China’s decision to throw its inexperienced industry into development of a second indigenous airliner before finishing its first, the ARJ21. Indeed, the C919 was launched in May 2008, six months before the ARJ21 even flew.

The schedule is unusually important to the C919—not because it is under binding contracts for delivery on time in 2016 (it is not), but because Western competition is mounting. Already Airbus and Boeing, launching the A320NEO (new engine option) and 737 MAX, respectively, have probably obviated the C919s chance to be the most efficient narrowbody in its early years on the market (see p. 26). Beyond that, the replacements for those Western aircraft, whenever they appear, will likely render the C919 obsolete.

C919 Program

"C919"is the short form of trunk liner code for "COMAC919". COMAC is the acronym of the Commercial Aircraft Corporation of China, Ltd. The letter "C" is the first letter of both "COMAC" and "China". It indicates that this trunk liner program is the will of China and her people. It is a short-medium range commercial trunk liner that can claim indigenous intellectual property. Its all-economy class layout entails 168 seats, and the hybrid class layout 156 seats. The basic version is designed to cover a range of 4,075 km, while the enhanced version can stretch to 5,555 km. Such designs may satisfy the operating demands for different routes. Its economic life is designed to be 90,000 flying hours/30 calendar years.

They need to get the ARJ-21 certified and delivered first before talking about "New"plans.
It's already three years behind schedule and it just a licensed copy of a MD-90 without anything new.

sour grapes.
it's chinese Independent research .from design to produce.

什么是“自主研制”呢?(1)飞机不是某个先期问世飞机的拷贝或翻版,测绘仿制不能叫“自主研制”;(2)完全依靠我们中国人自己的力量完成飞机的总体、气动设计和综合集成,外国人不能分享飞机型号合格证(TC);(3)不是纯生产型项目,不是生产许可证(PC)的延伸。

  “自主研制”可以包括“自主创新”、“集成创新”和“引进消化吸收再创新”的各种创新成分。飞机作为一种产品,在形成飞机批量生产之前是通过“项目”来执行的,即研制。而“项目”(Project)的典型特征是临时性、独特性和渐进明细。所谓“独特性”,它执行的结果不应该是某个已经存在的产品的复制品。

Although ACAC refers to the ARJ21 as "designed by Chinese with completely independent intellectual property rights", it is being built using tooling which was originally provided by the McDonnell Douglas Corporation for licence-production of the MD-90 in China. Consequently, it bears a strong resemblance to the DC-9 family of aircraft, with an identical cabin cross section, nose profile and tail. . An all-new supercritical wing, which has a sweepback of 25 degrees and is fitted with winglets to improve aerodynamic performance, was designed by Ukraine’s Antonov.Antonov Design Bureau also assisted the project with geometrical determination and integral analysis of the construction strength of ARJ21.

chinese Independent research? Yeah sure.

Yes, China used to make MD-90 as license production.


But what the article is telling us, is that the ARJ-21 has an identical cross section, identical nose and tail profile to the MD-90. So, it appears that they took the MD-90specs (which they have been license producing) and put in an all new wings (which is being designed by Antonov). The engines are also foreign and most of the avionics come from US too.

In my opinion, its the right thing to do to gain experience in designing and manufacturing aircraft by starting this way, and gradually introducing their own parts and new improvements in design before one day embarking on a completely new design.

The C919 would be an interesting thing (hopefully) but they need to get them up and flying quick before competition comes from improved Boeing and Airbus products.

since you would like use the wiki article which almost everyone could edit as the reliable source...

http://en.wikipedia.org/wiki/McDonnell_Douglas_MD-90

Quote:
A total of 40 MD-90s (later 20) were to be assembled under contract in Shanghai, People's Republic of China under the Trunkliner program,[13][14] but Boeing's decision to phase out the MD-90 resulted in only two built by Shanghai Aircraft.[15]
and I don't think a MTOW around 70 tones jet and another around 45 tones one are the same.

------------------------

ARJ and C919 are two indepedent projects developed by two teams and china has the fund and manpower surporting these at the same time...ARJ is on its way to get the Type Certification. the experience got here would help the C919 project in few years.

-------------------
the CJ-1000A (Changjiang) indigenous engine developed for C919 revealed early this month.
