Development

The ARJ21 is a key project, led by the government-controlled ACAC consortium, which began in March 2002 as part of China's "10th Five-Year Plan". The maiden flight of the ARJ21 was planned to take place in 2005 with formal handing over of the aircraft for use 18 months afterwards;cite web | title=China-Made ARJ21 Feeder Plane to Appear at Zhuhai Aviation Show | work=People's Daily | url=http://english.people.com.cn/200211/04/eng20021104_106234.shtml | accessdate=2002-11-04] however, the design work was delayed and the final trial production stage didn't begin until June 2006.cite web | title=Self-developed jet to fly maiden trip | work=XINHUA | url=http://news.xinhuanet.com/english/2006-06/01/content_4631760.htm | accessdate=2006-06-01] The first aircraft was rolled out on 21 December 2007 with plans for a maiden flight in March 2008,, however this has been delayed until September 21 2008 [name="China Gate"] , and the aircraft is expected to become available to buyers in September 2009. The ACAC consortium aims to manufacture 11 ARJ21s a year by 2010, and 50 per year by 2015.

Design

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 company for licence-production of the MD-90 in China. Consequently, it bears a strong resemblance to the DC-9 series of aircraft, with an identical cabin cross section, nose profile and tail. The general designer of the aircraft was Mr. Wu Guanghui (吴光辉), and the deputy general designer was Mr. Zhou Jisheng (周济生), with the general engineer was Ms. Jiang Liping (姜丽萍, 1968- ). An all-new supercritical wing, which will have a sweepback of 25 degrees and be fitted with winglets to improve aerodynamic performance, has been designed by Ukraine’s Antonov.

In addition to the baseline and the stretched passenger models, ACAC has also proposed extended-range, freight, and business jet variants.

Manufacturer

Members of the ACAC consortium, which was formed to develop the aircraft, will manufacture major components of the aircraft:
* Chengdu Aircraft Industry Group: construction of the nose
* Shanghai Aircraft Company: final assembly
* Shenyang Aircraft Corporation: construction of the empennage (complete tail unit)
* Xian Aircraft Company: construction of the wings and fuselage

The Shanghai Aircraft Research Institute and the Xian Aircraft Design and Research Institute, which are also members of the consortium, are responsible for the design.

Variants

* ARJ21-700 – baseline model which will have a capacity of 70 to 95 passengers.
* ARJ21-900 – stretched fuselage model based on the ARJ-700, which will have a capacity of 95 to 105 passengers.
* ARJ21F – dedicated freighter version of the ARJ21-700. It will have a capacity of 5 LD7 containers or PIP pallets, with a maximum payload of 10,150 kg.
* ARJ21B – business jet version of the ARJ21-700. A typical configuration would cater for 20 passengers.
