The Hongdu L-15 Falcon (猎鹰) is a supersonic training aircraft / Advanced Jet Trainer aircraft and light attack aircraft being developed by Nanchang-based Hongdu Aviation Industry Corporation (HAIG) to meet PLAAF/PLANAF Lead-In Fighter Trainer (LIFT) requirements.
[edit] Design and developmentThe L-15 is an advanced trainer aircraft currently under development by Nanchang based Hongdu Aviation Industry Corporation. The aircraft made its maiden flight on 13 March 2006. The aircraft's general designer is Mr. Zhang Hong (张弘), and the development is reportedly assisted by Yakovlev OKB of Russia. The L-15 is a direct rival to the Guizhou Aircraft Industry Corporation (GAIC) JL-9/FTC-2000 Mountain Eagle in competition for the People's Liberation Army Air Force's (PLAAF) next-generation advanced trainer aircraft program. HAIG unveiled a full-scale mock-up of its L-15 advanced lead-in trainer (LIFT) in the 2004 Zhuhai Airshow. The two-seat, two-engine L-15 features the latest advanced technologies developed by China, such as digital quadruple fly-by-wire (FBW), glass cockpit (two multi-color head down displays for both the front and rear cockpit, and an additional head-up display for the front cockpit), and hands-on-throttle-and-stick (HOTAS) flight control. The look-down field of view for the frontal cockpit is 18°, and 6° for the rear cockpit, exceeding the US requirement. The aerodynamic performance of the aircraft is enhanced by its large leading edge extensions (LEX) design, which gives a maximum angle of attack of 30°. This is very useful when trying to simulate the maneuvers of advanced fourth-generation fighters such as J-10 and J-11. With the L-15, student pilots will be able to complete mission flight training and advanced combat training, as well as complete all basic jet flight training courses. The aircraft also has six (four under-wing and two wingtip) pylons to carry various air-to-air and air-to-ground weapons. If necessary, it can serve in the lightweight attack role with minor modifications, carrying up to 3 tons of armament. The first L-15 prototype (#03) rolled out in September 2005 and made its maiden flight on 13 March 2006, piloted by the two of the chief test pilots of the program, Senior Colonel Yang Yao (杨耀) and Senior Colonel Zhang Jingting (张景亭, unrelated to the chief designer Zhang Hong). The 3rd chief test pilot of the program is Senior Colonel Li Zhonghua (李中华). Currently, Hongdu is actively marketing the aircraft to both domestic and international markets. In April 2006, it was reported that the PLAAF placed orders for 4 L-15 trainers, and small batch production will start in 2007.[1] Each of the first two units (#01 & #02) are powered by two ZMKB-Progress (Lotarev) DV-2 engines, which do not have afterburners, and these two aircraft thus do not have the capability to reach supersonic speed. The third unit (#03) is powered by a pair of an improved version of DV-2, the DV-2F, with afterburner, so that it can and has already reached supersonic speed. The subsequent production units are expected to be powered by Ukraine's Ivchenko-Progress AI-222K-25F turbofan engines with afterburner once co-production license is obtained by the 618 Institute.
