“Making DSIs resistant to hot gas ingestion...”

Was this an issue for F-35C?

Clearly, the J-31 is going to be the PLAN next Naval Fighter. So, why we keep talking about the J-20 is beyond me???

Plus, you must be kidding about the Su-34 having an "impressively low RCS". Was that a joke that I missed???

I agree that the J-31 is going to be the next PLAN fighter, I just don't think it's the best choice. And the Su-34 statement caused me to question my coworker. All he was allowed to say was low positive decibels. That was not the first time I have heard of the Su-34 having "extensive RCS reducing treatments". I myself don't see it, even if that platypus nose is a huge part of it.

AFAIK, the DSI (and engine) for the F-35C is, when used in conjunction with ABLIM, very HGI tolerant.

HGI was a major issue for the S-ducts (and engines) on the Super Bug which led to ABLIM in the first place.

I'm guessing there is a difference between HOT GAS INGESTION HGI & Catapult STEAM INGESTION (non-issue for EMALS)?

Steam ingestion was not a problem for the F-35C but like the Super Hornet HGI 'POP' Stalls were eliminated by ABLIM.

FOUR PAGE PDF attached describes some of these issues. PRN means reprinted to reduce file size so URLS don't work.

That's right; HGI in this case is coming mainly from the afterburner.
I'm not sure about that article you attached; full afterburner, in the Super Bug at least, gets restored
after 5 feet of catapult travel not at the edge of the deck.

IIRC, there were other mods to the F414 to improve its pop-stall resistance.

I really don't see how you believe J-31 will be the next stealth fighter for PLAN's next fighter. It is no F-35B or F-35C equivalent. The F-35A isn't exactly ideal in that role but add in J-31's low TWR and high wing loading. Just a bad combination. J-15 is in the PLAN's future, not J-31.

Really??? Funny, it's been discussed for "years"....

Sorry, the J-15 is just a "stop gap" until the Naval J-31 arrives..... :wink:

Back to topic. Spazz id like your personal opinion on who is the #2 navy behind the USN. Will the very potent F-35B make up for the lack of Numbers Britian faces?

The question needs a context. Are we bearing in mind QE class may be carrying 36 F-35Bs - apiece - capiche? No contest.

Another old official RAF 2013 reference to the F-35B gun pod as indicated.

How does the QE F-35B compare to other navies
