The Guizhou JL-9, also known as the FTC-2000 Mountain Eagle (Shanying) is a 2-seat [Vous devez être inscrit et connecté pour voir ce lien] being developed by the [Vous devez être inscrit et connecté pour voir ce lien] for the [Vous devez être inscrit et connecté pour voir ce lien] (PLAAF) and the [Vous devez être inscrit et connecté pour voir ce lien] (PLANAF).[Vous devez être inscrit et connecté pour voir ce lien]

Development

The Guizhou Aircraft Industry Corporation first revealed its intention to develop a new generation of fighter-trainer to replace its own JJ-7 fighter-trainer at the 2001 [Vous devez être inscrit et connecté pour voir ce lien] to meet new PLAAF trainer requirements to prepare pilots for China's newest generation of fighter aircraft such as the [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien] derived aircraft like the [Vous devez être inscrit et connecté pour voir ce lien], [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien].

The 'FTC-2000' designation indicates an interest in exporting the JL-9 to the international market, likely to countries already operating Guizhou's FT-7 (the export designation for the JJ-7) fighter-trainers.

In order to reduce both, the development time and development costs of designing an entirely new aircraft, it was decided that the aircraft would be based on the existing [Vous devez être inscrit et connecté pour voir ce lien], which itself is based on the [Vous devez être inscrit et connecté pour voir ce lien] ([Vous devez être inscrit et connecté pour voir ce lien] "Mongol") fighter-trainer.

The JL-9 made its maiden flight on December 13, 2003, only two years after the start of the project, making it the shortest
development time for an aircraft in Chinese aviation history, while successfully keeping costs down.

In June 2005, Chinese newspapers have stated that the JL-9 would be part of the [Vous devez être inscrit et connecté pour voir ce lien]'s 11th five-year procurement plan.

In 2006, Guizhou reported that five production aircraft have been accepted into PLAAF service.

Trials continue on the JL-9 and in 2006 an improved JL-9 with a stability control augmentation system and [Vous devez être inscrit et connecté pour voir ce lien] were tested. In Sep 2009, JL-9 passed all technology certification tests, which clears the way of entering series production for both PLAAF and PLAN.

In January 2011 a JL-9 with a tailhook was observed to be in flight testing.

This seems to indicate that the JL-9 will be used to train new fighter pilots for carrier operations instead of retraining PLANAF pilots.

Design


The JL-9's key improvements over its predecessor, the JJ-7, is the redesigned forward fueslage, most notably the replacement of the old [Vous devez être inscrit et connecté pour voir ce lien], into a solid nose radome and two lateral intakes.

The JL-9 uses a tandem, one-piece windshield for the pilot and the instructor (who's seat is designed to be higher than the pilot's to assist their view).

The cockpit houses three XPS-2 colour multi-function displays and an electronics suite consisting of [Vous devez être inscrit et connecté pour voir ce lien], [Vous devez être inscrit et connecté pour voir ce lien], 1553B databus, [Vous devez être inscrit et connecté pour voir ce lien]/[Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien].

The JL-9 can also be fitted with a starboard [Vous devez être inscrit et connecté pour voir ce lien].

The JL-9 retains the same two-section, double-delta wing without leading edge flaps configuration of the J-7E fighter, which offers greater space for fuel capacity and greatly increasing the aircraft's [Vous devez être inscrit et connecté pour voir ce lien] compared to a conventional [Vous devez être inscrit et connecté pour voir ce lien] configuration.

The aircraft is built with the J-7E/G fighters computer aided design and manufacturing procedure which includes, numerical control processing, laser/electromagnetic tests, composite materials, and water jet cutting.

In order to reduce costs, the existing WP-13F(C) [Vous devez être inscrit et connecté pour voir ce lien] engine, fitted with an after-burner from the J-7E/G fighter is used, providing marked improvement over the JJ-7s WP-7B turbojet engine.

[Vous devez être inscrit et connecté pour voir ce lien] has reported that the new, and far more powerful Liming WP-14C Kunlun-3 turbojet engine will be used for the JL-9 in the future.

In another cost saving move, the JJ-7s mechanical flight control systems is also retained.

With the introduction of a solid nose randome, the JL-9 is capable of housing a variety of combat radar, the export designated FTC-2000 is currently being offered with the [Vous devez être inscrit et connecté pour voir ce lien].

The JL-9 has four underwing and one central hardpoints with a total payload of 2000 kg of weapons, such as short-range air-to-air missiles, medium-range air-to-air missiles, air-to-surface missiles, bombs, rocket pods and an integrated 23mm cannon.

There are also hardpoints for two underwing droptanks and another under the fuselage.

Unlike many other contemporary fighter-trainer aircraft, the JL-9 is a fighter sized aircraft which may lead to the development of an electronic-warfare aircraft or a light-attack aircraft in the future.

In total, the JL-9 offers a moderate improvement in performance, particularly at lower altitutdes, over the existing JJ-7 fighter-trainer.
