Chengdu J-9

Chengdu J-9 (Chinese: 歼-9) was a designation assigned to a Chinese interceptor aircraft that never progressed beyond initial studies. The J-9 was scrapped in favour of the Shenyang J-8, which was a safer technological bet for the limited Chinese aviation industry of the 1960s and 1970s. The J-9 designation is frequently confused with the much later Chengdu FC-1 fighter which is sometimes informally referred to as J-9 by aviation enthusiasts.

History

In late 1964 two indigenous fighter programs were initiated to follow up the MiG-21. The twin-engine project using the MiG-21's R-11F-300 powerplants was the J-8. The J-9 project ran in parallel with the J-8 project, but used a completely new single-engine airframe. It adopted the canard layout. The designed target maximum speed was originally Mach 2.4 at above 20,000 metres (66,000 ft) of altitude. In order to achieve this target, the J-9 was fitted with an 8,500kgf (19,000 lbf)-thrust turbojet engine and the 601 Institute initially used a tailless delta design. Development at this point shifted to the newly built 611 Institute and the Chengdu Aircraft Factory. At the beginning of the 1970s, the 611 Institute proposed a new design using a canard ahead of the delta wing (similar to the Swedish Viggen), but because it required new materials and know-how (plus having engine performance problems), it was not until 1975 that the design could be completed.

Chengdu

Chengdu, formerly romanized as Chengtu, is the provincial capital of Sichuan province in Southwest China, as well as a major city in Western China. It holds sub-provincial administrative status. The administrative area houses 14,297,600 inhabitants: 9,922,534 within the municipality's eleven urban and suburban districts and 4,375,066 in the surrounding satellite towns and counties. According to the 2010 census, with 10,484,996 inhabitants in its built-up (or metro) area including Guanghan City in Deyang and Xinjin County, Chengdu is the fifth-most populous agglomeration in China. Chengdu is one of the most important economic, financial, commercial, cultural, transportation, and communication centers in Western China. Chengdu Shuangliu International Airport is one of the 30 busiest airports in the world, and Chengdu Railway Station is one of the six biggest railway stations in China. Chengdu also hosts many international companies and more than 12 consulates. More than 260 Fortune 500 companies have established branches in Chengdu due to huge demand of Western China. In 2006, it was named China's 4th-most liveable city by China Daily.
