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.

"Chinese heart" for large aircraft makes steady progress
(WCARN.com, June 11)


Quote:
With the development of the Chinese-made large aircraft, a high bypass ratio turbofan engine project is also moving forward steadily.

Engine is known as the "heart" of large aircraft. Bypass ratio refers to the ratio between bypass airflow and core compression inlet airflow. A high bypass ratio turbofan engine is defined as bypass ratio greater than 4:1.

Since its low fuel consumption and low noise, high bypass ratio engine is widely used on large-scale military and civilian transport aircraft, as well as other large subsonic aircraft, such as the tankers, warning aircraft and antisubmarine aircraft.

A forum held by ACAE (AVIC Commercial Aircraft Engine Co. Ltd) and Aerodynamic Department of CSAA (Chinese Society of Aeronautics and Astronautics) was launched on June 6-7.

Forty agencies and more than 100 world leading experts and scholars discussed around the areas of combustion chamber and turbine components design and technology, new materials and new technologies at more than 10 speeches held during the two days.

According to the previously disclosed timetable, ACAE plans to finish the design of large aircraft engine test device and form the overall design integration, assembly, and test capabilities by 2016. ACAE plans to deliver the engine to users by 2020.

ACAE holds responsibility and plays the main part in China's large aircraft engine design and development project. It was founded in Shanghai in 2009. With the development of its headquarter and four centers - design center, assembly and test center, customer service center and major repair and overhaul center, it has gradually built a industrial chain system with design, research & development, manufacture and sales for commercial aviation engine.

ACAE said that they will integrate quality domestic and abroad resources to spur technological progress of China's domestic aviation industry, and promote its structural adjustment and upgrading.

The plane is still a decade away from being finished.

Hope ryanair orders it like they suggested to though.

some cross posts from the Mainland Chinese subforums:



Firan Technology Group Corporation signs Letter of Intent with Shanghai Avionics Corporation (SAVIC) for cockpit control panel assemblies used on the C919 aircraft

Quote:
Firan Technology Group Corporation announced today that it has signed a Letter of Intent (LOI) with SAVIC, based in Shanghai, China for the supply of Cockpit Control Panel Assemblies for the Display System of the C919 aircraft.

Under the terms of the LOI, FTG will design, develop, manufacture and supply the Display System Suite of control panel assemblies. The design, development and initial manufacturing will be completed at FTG Aerospace - Toronto and volume manufacturing will be performed at the division's facility in Tianjin, China.

SAVIC was selected by GE AVIC civil avionics joint venture to provide certain airborne avionics equipment for the C919 program and is planning to order 2,355 ship sets consisting of 9 control panel assemblies per set from FTG.

SAVIC and FTG have agreed to share the cost of the design and development of the control panel assembly products. Initial funding has been received from SAVIC and the program is now underway. Further discussions and negotiations are in progress with a view to concluding a long-term Master Agreement between SAVIC and FTG.

This Master Agreement will replace the LOI and cover all design, development, production and In Service Support (ISS) for the delivered products.

"This represents a tremendous opportunity for FTG to increase our value proposition in an important emerging market. FTG made a commitment to the China market in 2010 by establishing FTG Aerospace - Tianjin and we are pleased to see such significant results so soon", said Brad Bourne, President and CEO of FTG.

"SAVIC is dedicated to delivering more reliable and competitive avionics products to customers and is willing to build a long-term partnership with FTG. FTG's commitment to the China market and its localized manufacturing will benefit the C919 program", said Wang Guoqing, President of SAVIC.

"We are very excited to be a part of this strategic aircraft program with SAVIC", said Peter Dimopoulos, Vice President of Business Development at FTG. "Our continual focus on high quality, high reliability and best value offering were key factors in SAVIC's vendor selection process."

SAVIC is a high technology Chinese enterprise dedicated to the development and production of avionics and electronic products. SAVIC is a major provider of avionics products to the Chinese aviation industry and owned by Aviation Industry Corporation of China (AVIC).
