[edit] History

ARJ21 is a key project during the "10th Five Year Plan" period. The project began in March 2002, led by government-controlled ACAC consortium. According to the plan the ARJ21 was expected to perform its maiden flight in 2005 and be formally handed over for use another 18 months afterwards^[3]. However, the design work was delayed. The final trial production stage began in June 2006^[4]. The first flight is scheduled for March 2008, and the aircraft is expected to become available to buyers in September 2009. ACAC aims to manufacture 11 ARJ21s a year by 2010.

[edit] Manufacturer

The ACAC consortium was formed to develop the aircraft. The components of the aircraft will be manufactured by the members of the consortium:

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.

[edit] Variants

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

[edit] Future developments

Besides the baseline model and the stretched model, there will also be standard range and extended range versions, and also all passenger, freight and business jet variants.

[edit] Design

The ARJ21 will be built using tooling which was originally provided by the McDonnell Douglas company for licence production of the MD-90 in China. Because of this, it bears a strong resemblance to the DC-9 series of aircraft, with an identical cabin cross section, nose profile and tail. An all new supercritical wing has been designed by Antonov.^[5] It will have a sweepback of 25°, and be fitted with winglets to improve aerodynamic performance.
