A COMAC ARJ-21

The Comac ARJ21 Xiangfeng (Chinese: 翔凤; pinyin: xiángfèng; literally "Soaring Phoenix")[2] is a twin-engined regional airliner. It is the first regional passenger jet to be developed and indigenously produced by the People's Republic of China. This programme 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]

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 21 September 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) had rolled out by then, and completed the test flight on 12 September 2009.[8] By August 2011, static, flutter and crosswind tests had all been completed.[9] The aircraft was expected to be delivered to customers in late 2010, starting with Chengdu Airlines.[10] The ACAC consortium aimed 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.[11]

Delays

In November 2010, it was reported that the ARJ21's wing became damaged during static testing before achieving ultimate predicted load. The wing's failure then led the Civil Aviation Administration of China (CAAC) to limit the aircraft’s flight envelope during its flight test program. The new delivery date has been delayed to the end of 2011.[12]

On 24 August 2011, Flightglobal.com reported that two components of the testing program were not complete; icing tests were underway but delayed and stall speed tests had not begun. According to an anonymous source within the program that this could lead to delay in obtaining type certification, which could in turn lead to delays in delivery.[9]

Design

The Shanghai Aircraft Research Institute and the Xian Aircraft Design and Research Institute claim to be responsible for the design.

Although ACAC refers to the ARJ21 as "designed by Chinese with completely independent intellectual property rights",[13][14][15] 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.[16][17][18] Antonov Design Bureau also assisted the project with geometrical determination and integral analysis of the construction strength of ARJ21.[16]

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:

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.
