JF-17/FC-1 Fighter Aircraft thread

I normally don't download or upload JF-17 photos but I think these ones of the PAF airshow team is just really pretty photos. It's good to see these guys putting up a good show. It might help with export sales.

I was fortunate enough to witness a flight demonstration of the Russian Knights with MiG-29's and Su-27's here - the last time they visited in Manila.

One thing that I remember clearly was how smokey the Tumansky R-33's were on the MiG's - lots of dark smoke on afterburner.

The AL-31's on the Sukhoi's were a lot less smokey.

The pics you posted show how little smoke (if any) there is with the new R-93's are on the JF-17.

Is this due to the fact that the newer engines are less smokey or that the DSI makes for less smoke?

Engine smoke (excluding those caused by engine fires of course) is caused by poor air fuel mix ratios which results in some of the jet fuel not being burnt in the engine, so escapes through the exhaust as smoke. The intake will have nothing to do with this. It will be better and more modern engines that reduces smoke. Stick a rd33 in a jf17 and it will smoke as badly as any mig29.

How come that over Vietnam the MiG-21's produced much less smoke than US aircraft and now an engine from the same house smokes more?

Mig-21 are powered by turbojet, Mig-29 are powered by turbofan. Big difference

Surely the functioning of the burners is independent of the amount of air by-passed around the engine.

Maybe the engine simply produce more smoke when accelerating just like cars do because fuel flow is increased faster than air flow can catch up ?

The RD-93 are definitely upgraded variants of the RD-33 engines. Compared to RD-33 TVC version that Mig-35 supposedly uses, the only thing RD-93 doesn't have are the TVC. The newer variants of RD-33 basically have fixed a lot of the older problems.

Gentlemen, I have a few questions to ask regarding the dog fighting capabilities of the FC-1 over that of the F-16A, block 15 of the Pakistani inventory. Granted that the F-16A’s do not have the BVR ability of newer (upgraded F-16’s), and with the heavier conformal fuel tanks and electronics package on these “upgraded” F-16 would give the FC-1 an even better advantage in a dogfight.
How do you see a potential skirmish between an FC-1 and an F-16 block 40/50? Given that ground, or air control is equal. Assuming that the F-16 has AIM-120, or Derby AAM
What type of radar and or missile system would the FC-1 need to employ to obtain the first punch against an F-16(block 40/50) employing the above mentioned missiles?
I seems as if the FC-1 is a better buy than second hand F-16’s. I have also heard (not on SinoDefence, so I take it with a grain of salt) that the FC-1 requires less maintenance hours than an F-16.

Thanks,

I was also impressed by the wealth and quality of photos coming out of this year's Zuhai Air Show. Made my eyes water. Some really beautiful shots there.

A short article appeared on prospective sales for the JF-17, coming out of the Zhuhai Air Show.

Although names of prospective clients are not mentioned, they did quote Zeng Wen, vice-president of the China National Aero-Technology Import and Export Corporation (CATIC), as saying that "We’re talking with six to eight countries about the JF-17." The usual, likely customers (Egypt, Sri Lanka, Venezuela, and various sub-Saharan African nations) are also pointed out.

What I found more interesting was the following admission:

China's People’s Liberation Army Air Force has not yet signed up for the fighter, but Zeng says: "We believe the PLAAF will consider the JF-17. They are watching the programme very closely."​

Which confirms what many of us had already suspected. Despite whatever assurances about Chinese support may have been delivered to Pakistan, the PLAAF has not ordered this airplane, and there are no guarantees that they ever will. The JF-17 is a fine airplane for the role in which it was intended, but it lacks the range and payload of its larger counterparts. The PLAAF has a far more vast border to patrol than Pakistan does, and needs the greater range and capabilities that the J-10 and J-11 can afford.
