JH-7/JH-7A/JH-7B Thread

Re: JH-7/JH-7A Thread

If they're supersonic with turbojets they would require some afterburner stage and it does not look that way.

Furthermore there are similarities with the C-201 or C-301 supersonic ramjet missiles which China had experimented.

As for rockets, all you need is to dual use the ramjet combustion chamber as a rocket motor by filling it with rocket propellant. Once the propellant is burned away, it clears the chamber to be used as a ramjet. Already the Sunburns and Kryptons use this principle.

CHINA DEVELOPING SHIPBORNE COMBAT AIRCRAFT TECHNOLOGIES


The high-quality Google satellite photos indicate that one folding wing JH7 “Fei Bao” fighter-bombers is fielded at Dachang Airport in Shanghai. This means that China has started to develop fighter folding wing technologies. The 16th Regiment of Navy Aviation Force No.6 Division is stationed here.

Re: JH-7/JH-7A Thread

I doubt its ramjet, as I'd expect to see a rocket phase which I can't really imagine being incorporated into the two exhauses. I expect its turbojet but with longer intake ducts to allow supersonic flight - but no indication of variable intake although these are airshow models so I doubt they'd show that sort of detail anyway.

I expect it to be ramjet and incorporating a rocket phase into the ramjet is one of the technical issues that China appeared particularly interested to study on the Krypton and the Sunburn missiles. I was expecting they should have something to particularly incorporate that principle.

Re: Jh-7 thread

Re this jet powered missile that keeps appearing on JH-7 models, any news on what it is?

It appears to have a rear radome... or is that a parachute housing...

just appeared on a chinese military news website.

Translation:

CAC displayed a mock-up model of the new fighter-bomber FBC-1 "Flying Tiger." A mysterious missle carried by the model has gotten a lot of attention. This missle is one of the latest indigenous conceptual plans - air-launch land/sea attack cruise missle.

The missle has similar appearance to Kh-35, but differs in that the air inlet does not extend all to way to the tail.

It can be used to attack strategic land targets and large surface ships.

The missle uses GPS+Inertial for mid-flight guidance, and active radar+infrared imaging for terminal guidance. It's powered by an integrated solid-fuel rocket+ramjet engine.

The length of the rocket is 4.18m, largest diameter is 560mm, smallest diameter is 320mm. Total weight is 980kg, with a 300kg warhead.

The missle can be launched at an altitude of 10-20km at 0.8M-1.5M. Cruising altitude is 15-20km. Typical cruising speed is 4.0M and range is 400km.

It sounds like this missle is still a conceptual plan, until we see a real photo of it.

I think KANWA is wrong !!!

I don't think that this is an experimental carrier-capable version and not even a testbed for folding wings !

First, the JH-7 is much too heavy and underpowered to be carrier-capable and all efforts to re-engine it would be a wast of time and money as more moderne designs are much more capable (Su-33 or the twin-sticker Su-33UB) and therefore it would be senseless to build a real-flying machine only to test a folding wing - that would be possible much easier on a static testbed.

Additional if You take a look slightly further away from that "JH-7 with folding-wings" You can see the rest of the wing ! I admit that I don't know if the complete upper wing structure could be removed for maintanance or the outer wing parts ... maybe this particular aircraft had an accident .... !

Additional this "high-quality" picture of Shanghai-Dachang has been updated since with a much higher resolution showing still the same situation with the same row of JH-7 all complete with their wings, also the same Boeing 707 (????) is parked in the lower corner and some "remains" of wings are still visible ...

I don't know if some of these Google-pictures have mistakes or errors .... for exaple if You take a look at the Airbus factory at Hamburg you can find a half-Airbus maybe because the picture is composed from different pictures taken at different moments.

there's mention of carrier version of JH-7 way 3 years ago,but I suspect it could be private venture.or even demontrator,
You are right, for carrier aircraft, the JH-7 may require more powerful engine.
the aircraft was slightly underpower.

Re: JH-7/JH-7A Thread

Thanks, tphuang.

I guess I've seen that photo before. If it was photshopped, why leave wing-tips off to the side if someone faked it? Or is this just maintenance on the wings?

It's Google Earth, not Photoshop. I think the wings were just taken off for maintenance.
