The Shenyang JJ-1, also known as the Hong Zhuan-503 or Red Special, was a jet trainer developed in the People's Republic of China (PRC) during the 1950s. Two prototypes flew, but further development was abandoned.

Design and development

Due to differences in ideology the Soviet Union severed relations with the PRC in the early 1950s, robbing the PRC of access to modern Soviet technology, particularly aircraft and aviation related items. To ensure that the People's Liberation Army Air Force could re-equip and train to fly jet fighters Shenyang Aero Institute (Shenyang) were approached by the PLAAF to design and build a prototype jet trainer.

To fill the PLAAF requirement, the designers at Shenyang produced the JJ-1, a straight-winged aircraft, with a retractable tricycle undercarriage, tandem cockpits with a side hinged canopy over the front cockpi and rearward sliding canopy over the rear cockpit (very similar to the Shenyang JJ-5) and intakes either side of the front cockpit.

Power was supplied by a Shenyang Aircraft Development Office PF-1A, (Chinese copy of the Klimov RD-500 / Rolls-Royce Derwent), centrifugal compressor turbojet fitted in the centre fuselage, exhausting through a jet pipe extending to the tail of the fuselage. Armament was to have been a single 23 mm (0.906 in) calibre automatic cannon.

Production was not carried out as it was found that pilots could transition to basic jet fighters from propeller driven fighters with few problems.

Operational history

Testing was carried out on the two prototypes and static test airframe before development was cancelled.
