The ACAC ARJ21 Xiangfeng (翔凤 Flying Phoenix) is a twin-engined regional airliner, and 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), Honeywell (Fly-By-Wire system) and Rockwell Collins (avionics production).

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; however, the design work was delayed and the final trial production stage did not begin until June 2006. The first aircraft was rolled out on 21 December 2007 with plans for a maiden flight in March 2008; however this was first delayed to September 21 2008and finally took place on 28 November 2008. 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 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. Antonov Design Bureau also assisted project with geometrical determination and integral analysis of the construction strength of ARJ21.

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
  • Xian Aircraft Company: construction of the wings and fuselage
  • Long list of component's supliers include: Microtecnica (Italy), EMTEQ (USA), Static Dischargers: HR Smith Ltd (UK), LISI Aerospace (France), Goodrich Interiors (DE), Bell-Memphis, Inc. (USA), Hartwell Corp. (USA), Rockwell Collins (USA), Technofan (France), Machined housings: AJR Industries, Inc. (USA), ALCOA, Inc. (USA), C.E.S.A (Spain), Fischer Advanced Composite Components AG (Austria), AMETEK Airscrew Ltd. (USA), Liebherr-Aerospace Lindenberg GmbH, MTI Polyfab - Canada, Dunlop Aircraft Tyres (UK), Kavlico Corporation (USA), B/E Aerospace Inc. (UK), Eaton Aerospace, Electric Distribution & Controls (USA), Honeywell Aerospace (USA), Rockwell Collins (USA), Sagem Défense Sécurité (France), Enhanced Vision Systems, Rockwell Collins (USA), Hamilton Sundstrand Power Systems (USA), Aerotech Herman Nelson, Inc., Goodrich Turbomachinery Products, Techspace Aero S.A., ALCOA, Inc. (USA) and General Electric CF34-10A (USA)

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.
