J-10 Thread III (Closed to posting)

[siegecrossbow]

Not necessarily, sometimes it could be a software glitch, or such a failure that affects only displays, but computer responsible for control of the aircraft is still operational and responds on pilots input normaly. I'm not sure if such cases have happened to F-117, but in some commercial planes like Airbus A320 it happened several times, and pilots managed to land normally. All other electronics worked normaly, but screens were black.

Well the thing is Airbus A320 is a stable airframe. Similarly shaped aircrafts have been flying without FBW fine for the past 50 years or so. J-10 is a delta-canard so I am not sure whether it could stay level when the computerized controls cease to work.

Does anyone here know whether the J-10 that suffered a engine failure in 2009 still had auxillary power when it was safely landed by the pilot?

I'm pretty sure the plane had some electricity left. Normally there's systems in planes that run on AC, others run on DC.
When the engine and with it the generator fails AC will most likely get lost. And I'm not aware the J-10 has an auxiliarry power unit on board.
But any airplane has a battary that will power some systems for some time that are enough to get you home, normally.
It probably also has a static inverter to use some DC battary power as AC, for some instruments.
But you probably have to be fast and it won't be nice

If unstable airplanes lose their computers then yes they are pretty screwed indeed, but again if you loose your fancy glass cockpit instruments you will be happy to have a backup. Or you need another plane to fly back on it's wing.

Thnx for the answers Dexy & Scratch! I've been wondering how unstable planes handle power loss for some time now.

Additionally, single engine planes normally have an emergency power unit. It contains hydrazine (toxic) in a nitrogen charged bottle & water. When the engine fails, these two are released and mixed over an iridium catalyst (sais wiki). The mixture then spontaneously ignites, with the expanding gases driving an emergency turbine for power and hydraulics.
I don't exactly know, however, how modern unstable twin engine aircraft would handle a dual engine flame out, i.e. if they have the same safty measures or if they just rely on the second engine as backup.
Anyway, this got me wondering now, does the J-10 have an APU onbord for independent engine starts and stuff? I would assume so, but don't actually know.

 

[siegecrossbow]

Thnx once again Scratch. You've been of great help!

Does any one here know the precise number of J-10s currently in service in the PLAAF and if not, a good estimate? The numbers on wikipedia used to be 190 but now they changed it to 90 (goes to show how unreliable it is as a source).

 

[plawolf]

There have been well publicized stories of a J10 pilot 'gliding' his plane back to base after an engine flame out. That would pretty much confirm that it has a batter or some form of APU.

 

[dexy-sexy]

On Eurofighter Typhoon APU exhaust is clearly visible due to a dark smudge around it caused by hot gases from APU on start up.
I tried to find picture of J-10 with similar trail, and found one that looks like APU exhaust, first one has that smudge, but the other one is clean, although it shows an exhaust pipe.

I think 1000 J-10s should be build and deployed by 2025. USAF at its peak has 990 F-16s so China should follow suit. Such a huge number of J-10s would also remind Japan, South Korea, India, Vietnam and Taiwan that China is no longer just a regional power but a global power equal to USA by 2025.:china:

Now a post like this is hardly constructive, isn't it?

Would you kindly second your proposition with more details re. objectives, feasibility or possible outcomes and so on?

Or maybe just read the forum rules before you post?

China ain't gonna have that many J-10 that's for certain. Vietnam is no threat to China, and India airforce isn't a threat either due to the geography. Nor will they stupidly attack. ROC will retaliate of course if PRC tries to reclaim the island back, South Korea is actually getting more friendly with China now. Only credible intervention of war is Japan. USA ground units didn't use body armor in WWII, China should follow suit?

China focus is economy and its people, the military is there to defend it. That is the moto.
