The first Y-9 prototype is shown here parked at CFTE airfield.




The design was first unveiled at the 11th Beijing Airshow in September 2005. Y-9 is the next generation medium-size and medium-range transport aircraft to replace the obsolete Y-8 series transport aircraft. It appears to have superceded the earlier Y-8-X project (initially dubbed Y-8U?). The aircraft features a spacious cargo cabin which can quickly load/unload maximum 20t containerized cargo, or airdrop 13.2t equipment or 98 paratroopers. It also has a 4-crew cockpit featuring 6 color MFDs and EFIS.

The aircraft is equipped with advanced communication, navigation, radar, EGWPS, collision avoidance systems to ensure safe flight under all weather conditions. The aircraft will be powered by 4 WJ-6C turboprops (rated @ 5,100ehp each) with JL-4 6-blade propellers made of composite materials, which improve its high temperature and high altitude performance. Some specifications: max TO weight 65t, max payload 20t or 106 paratroopers, 15t payload range 2,200km, max range 5,000km, max level speed 650km/h, cruise speed 550km/h, service ceiling 10,100m, cruise altitude 8,000m. The development of Y-9 started officially in October 2005 and the construction of the first prototype (tail and head sections) started in 2006.

However the project appeared to have been halted in 2007 due to shifting the production to the high priority High New series as well as Y-8C transport aircraft. The developement of Y-9 resumed in late 2008 after the two year delay and the first prototype was rumored to have made its maiden flight on November 5, 2010.

Yun-9 Multipurpose Transport Aircraft


At the September 2005 International Aviation Expo held in Beijing, Shaanxi Aircraft Industry (Group) Co. Ltd unveiled its Y-9 multi-purpose transport aircraft design. A substantial redesign of the Shaanxi Y-8 (Chinese copy of the An-12 Cub), the aircraft was initially revealed to the public at the 2002 Zhuhai Air Show under the name of Y-8X concept transport. It is said to be comparable to the U.S. Lockheed Martin C-130J transport in general performance.

The development of the Y-8X began in 2001 to meet the requirements of the PLA Air Force for a capable and advanced medium-size tactical transport aircraft to replace the ageing Y-8. The project aims to develop a multi-purpose turboprop transport aircraft that approaches or in some aspects exceeds the performance of the U.S. C-130J. The development is believed to have been assisted by The Ukraine-based Antonov Aeronautical Scientific-technical Complex (ASTC) aircraft company.

During the 2005 Beijing International Aviation Expo, Shaanxi revealed more details about the Y-8X, now re-designated Y-9. Compared to the Y-8, the new aircraft features a more spacious cargo cabin, fast loading/uploading system, improved WJ-6C turboprop engines, six-blade propellers, and a “glass cockpit”. The aircraft can be used for both military and civil flights.

The Y-9 ’s wings are high-mounted with four turboprop engines mounted under the wings’ leading edges. The aircraft utilises six-blade JL-4 propellers made of composite materials. The rear cargo door, which also serves as a ramp, allows cargo to be quickly loaded/unloaded. The tail flats and fin are mounted high. The aircraft has a two-wheel nose landing gear and two four-wheel main landing gears.

The payload requirement of the Y-9 includes a range of military vehicles, helicopters, cargo containers, pallets, and paratroopers. The Y-9 can air-drop paratroops and equipment either by parachute or gravity extraction. It can perform wither single or multiple airdrops of paratroopers and cargo. The aircraft can carry nine international standard pallets of 108'' X 88'' or eight 125'' X 96'', or 132 armed paratroopers.
