The Comac (formerly ACAC) ARJ21 Xiangfeng (Chinese 翔凤 xiángfèng, Soaring Phoenix)[2] is a twin-engined regional airliner. It is the first passenger jet to be developed and indigenously produced by the People's Republic of China. This program is supported by 19 major European and US aerospace components suppliers, including General Electric (engine production),[3] Honeywell (fly-by-wire system) and Rockwell Collins (avionics production).[4]

[edit] 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;[5] however, the design work was delayed and the final trial production stage did not begin until June 2006.[6] The first aircraft (serial number 101) was rolled out on 21 December 2007 with plans for a maiden flight in March 2008;[2] however this was first delayed to September 21, 2008 and finally took place on 28 November 2008 at Shanghai's Dachang Airfield.[7] It completed a long distance test flight on 15 July 2009, flying from Shanghai to Xi'an in 2 hours 19 minutes, over a distance of 1,300 km. The second ARJ21 plane (serial number 102) completed the same test flight from Shanghai to Xi'an on 24 August 2009. The third plane (serial number 103) has rolled out by then, and completed the test flight on 12 September 2009[8]. The fourth plane (serial number 104) is in the process of being assembled. The aircraft is expected to be delivered to the customers from late 2010. The ACAC consortium aims to manufacture 11 ARJ21s a year by 2010, and 30 per year by 2015. In 2009 the consortium was reorganized and became a part of COMAC (Commercial Aircraft Corporation of China)[9].
[edit] Design
Although ACAC refers to the ARJ21 as "designed by Chinese with completely independent intellectual property rights",[citation needed] 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 will have a sweepback of 25 degrees and be fitted with winglets to improve aerodynamic performance, has been designed by Ukraine’s Antonov.[10][11][12] Antonov Design Bureau also assisted project with geometrical determination and integral analysis of the construction strength of ARJ21.[10]
In addition to the baseline and the stretched passenger models, ACAC has also proposed extended-range, freight, and business jet variants.
[edit] 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
- Xian Aircraft Company: construction of the wings and fuselage
- Shenyang Aircraft Corporation: construction of the empennage
- Shanghai Aircraft Company: final assembly
- Various domestic and international suppliers of component's suppliers.[13]
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.
[edit] 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.
