Chengdu J-10
The Chengdu J-10 (Chinese: 歼-10; pinyin: Jiān-Shí), also known as Menglong (Chinese: 猛龙; pinyin: Měnglóng; lit. 'Vigorous Dragon', NATO reporting name: Firebird) is a Chinese medium-weight, single-engine, multirole combat aircraft using a delta wing and canard design, with a maximum speed of Mach 1.8. It is produced by the Chengdu Aircraft Corporation (CAC) for the People's Liberation Army Air Force (PLAAF) and People's Liberation Army Naval Air Force (PLANAF) of China, and exported to the Pakistan Air Force (PAF).
In 1981, PLAAF Commander Zhang Tingfa submitted a proposal to Deng Xiaoping for the development of a third-generation fighter for CN¥ 500 million; it was accepted later that year by the Central Military Commission (CMC). It was the first Chinese aircraft program to incorporate modern development and acquisition processes. In one departure from the past, the supplier was now responsible directly to the customer; this allowed the PLAAF to communicate its requirements and ensure they were met; previously suppliers were responsible to their managing agency, which could produce products that failed to meet end user requirements. Another difference was the selection of a design through competition, rather than allocating a project to an institute and using whatever design that institute created.
Design proposals were made by the three major aircraft design institutes. Shenyang's proposal was based on its cancelled J-13 with a F-16-like strake-wing. Hongdu's proposal was MiG-23/Su-24-like with variable-sweep wing. Chengdu Aircraft Design Institute's (CADI) proposal was a Saab 37 Viggen-like design based on its cancelled J-9. CADI's proposal was selected in February 1984. The following month, CADI and Chengdu Fighter Factory were formally directed to develop and manufacture the aircraft, respectively. Song Wencong (宋文骢) became chief designer.
The engine was selected during the design proposal stage. Candidates were an improved Woshan WS-6, the WP-15, or a new engine. The new engine, ultimately the Shenyang WS-10, was chosen in 1983.
The State Council and the CMC approved the program in 1986, code-naming it "No. 10 Project". Interest waned in the following years which constrained funding and prolonged development. The Gulf War renewed interest and brought adequate resourcing. Unlike earlier programs, the J-10 avoided crippling requirement creep.
Technical development was slow and difficult. The J-10 represented a higher level of complexity than earlier generations of Chinese aircraft. About 60% of the aircraft required new technology and parts, instead of - according to Chengdu - the usual 30% for new aircraft; the high proportion reflected both requirements and limited domestic capability. Development and modernization of China's aviation industry occurred alongside the J-10; the program was an early Chinese user of digital design, modelling, and testing including computer-aided design (CAD) and computational fluid dynamics. The J-10 was the first Chinese aircraft to make major use of CAD for its structural design, allowing the detailed design to be completed in 1994. The hydraulics system was tested with physical models because of limited digital modelling capabilities.
The first J-10 was assembled in June 1997. Lei Qiang flew the first flight on 23 March 1998; Lei was chosen for his experience with modern, foreign, third-generation aircraft. PLA training units received the J-10 ahead of schedule starting in 2003. Weapons tests occurred in the fall of that year. The design was finalized in 2004. Rumors of crashes during flight testing were actually mishaps related to the AL-31 engine.
The J-10 became operational in 2006. It was officially unveiled by the Chinese government in January 2007, when photographs were published by Xinhua News Agency.
