CHINESE J-31 STEALTH FIGHTER AIRCRAFT

The brand new 5th-generation fighterjet Shenyang J-31 – or F60, which would be nicknamed Gyrfalcon – took off on October 31, 2012. She thus performed a test flight – probably her maiden flight – on Wednesday.

This futuristic PLAAF (People’s Liberation Army Air Force) stealth multirole jetfighter looks like an F-35 Lightning II though the Gyrfalcon (or Falcon Eagle?) turns out to be a twin-engine a/c. She would be more maneuverable but smaller than the latest Chengdu J-20 Black Eagle stealth fighter. Her radar cross section (RCS) might be very small, and stealthier than recent 5th-generation fighter aircraft as the radome mounting looks as if it were – like the rest of the airframe – designed with reentrant shapes.

This fighter aircraft would not exceed Mach 2, and she features a DSI (Diverterless Supersonic Inlet) so that the airspeed can be reduced while entering the air intake, thus preventing the engine from breaking up.

Here are a few pictures, and videos:

The first J-20 BLACK EAGLE taxiing-test snapshots have popped up throughout the blogosphere for a few days. These so-called leaked pictures reveal a design that comes straight from the J-XX with the front part similar to the F-22 Raptor’s one, and the aft a bit like the Sukhoi PAK FA’s one.

Thanks to ChineseKungFu100, you can watch below a High-Definition video in which you can see a huge glass cockpit. It is believed that the J-20 is likely to be cheaper than the PAK FA / T-50, and far cheaper than the JSF F-35 and the F-22, with lower performance though longer radius of combat, and bigger strike capability. The shapes after the forward canards and the chine, may be low-RCS caret air intakes with DSIs – Diverterless Supersonic Inlets – which maintain high-quality airflow to the engines over a wide range of conditions. It is believed that the J-20 may have Russian engines. She is likely to be equipped with an AESA radar.

With this new fighter aircraft, and its brand new aircraft carrier, the PLAAF (People’s Liberation Army Air Force) could be on a par with the lead air forces in the world.
