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:

FIGHTERJETS compared: Sukhoi T-50 PAK FA vs F-22 RAPTOR

First of all, here is a video on the first T-50’s public display (Moscow – MAKS 2011, August 17, 2011):

The Lockheed Martin/BIDS F-22 Raptor, and the brand new Sukhoi T-50 PAK FA are the current leading-edge 5th generation fighter aircraft. Lots of people would like to assess the capabilities of the two fighterjets. However, no aircraft can be compared regarding its specifications only as fighter aircraft are designed within a wider system – radars; weapon systems; training; and sharing information through data links.

All we know is that the F-22, and the PAK FA are equipped with excellent AESA radars. Though still secret, the Raptor’s stealth is deemed to feature a record-breaking RCS (Radar Cross Section). The T-50, which is to be fielded within the Indian and Rusian air forces, might be equipped with anti-AWACS missiles. The Chinese Chengdu J-20 has not disclosed much information so far, but it will be interesting to this new 5th-gen fighter with the two other aircraft.

MACH-20 AEROSPACECRAFT

New-York to Los Angeles in 12 minutes… It would have been a record-breaker, had it worked:

The DARPA and USAF FALCON project might give anybody the thrill of speed as this « aerospacecraft » has been designed to reach Mach 20 i.e. around 20,000 km/h; 5.6 km/s; 10,800 knots; or 12,400 mph depending on the air temperature, and the altitude which might be above at least FL900!

Unfortunately, the project seems to encounter major difficulties as the last test which unfolded on August 11, 2011 failed again. The previous one – also on an HTV2 – had failed in April. Click on the right-hand side picture to get further information on the first test. The Blackswift (HTV-3X)  had been designed by ATK; Boeing; Lockheed Martin; and Skunk Works to provided a strategic strike anywhere in the world within an hour. It was cancelled due to a lack of funds (see the HTV-3 shown in the following video):

 


 

  • DARPA stands for Defense Advanced Research Projects Agency
  • FALCON stands for Force Application and Launch from CONtinental United States
  • FL stands for Flight Level (FL x 100ft = altitude)
  • HTV stands for Hypersonic Test Vehicle or Hypersonic Technology Vehicle
  • RCS means here in the videos: Reaction Control System (and not Radar Cross Section)

Chinese 5th-generation fighter « J-20 Black Eagle » HD video

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.
