South Korea Unveils Hypersonic Cruise Missile Prototype Concept | Aviation Week Network

Opposing hypersonic glide missiles developed by North Korea and China is crucial both militarily and politically to South Korea.

The AvWeek subhead writer needs a technology refresher course. That's not a glider.

It's referring to Chinese and NK gliders.

Oh, crud. My reading comprehension has been terrible today. Thanks.

Is it just me or does that look exactly like the X-51 with a different booster arrangement?

Pretty close. As does Zircon and Brahmos 2 (or whatever it's being called).

Are there actually pics of Zircon?

No just lots of artwork. Typically looks like this:

I wonder if the X-51 imagery isn't perhaps just a placeholder and not truly representative of any of the missiles. Zircon for instance I can't imagine being a pure scramjet given its rough dimensions and surface launch mode; the booster would have to be rather energetic for it to be a pure wave rider. The Russians have never explicitly described it as a scramjet; I suspect it is ramjet/scramjet hybrid that changes its intake geometry.

 

[sferrin]

Wouldn't surprise me. As for Zircon I read somewhere that it might not even be a scramjet but just a conventional ramjet. If so that would certainly be a record for ramjet speed.

For a dual-combustion ramjet (ramjet/scramjet) HyFly would be a good example. Didn't have VG intakes but completely separate flow paths as I recall.

[kqcke for you]

 

[Josh_TN]

Having a separate ramjet mode seems a little pointless, unless it is for initial acceleration. Just shut down the scramjet and dive on the target.

Lower altitude flight.

 

[Josh_TN]

Lower altitude flight.

Sure, but it is a lot of complexity for little gain. The advantage of a pure scramjet is no moving parts or inlets.

Depends how low it can go. Ground-level at Mach 3 would be very difficult to intercept.
