Do we know enough about the AIM174B to use those methods?
I doubt PL-21 will be any shorter-ranged, though. It isn't any smaller, but it's a tailor-made a2a missile.
nationalinterest.org
It is the same 5.7(or so) meters long; neither 250kg(barely heavier than much shorter and slimmer PL-15) nor 400km number seems plausible to me...and in any case, I suspect that source of this 400 number was KS-172, which is a really old design, dating back to final Soviet years.
It isn't a ramjet, there are no visible intakes; it's just a better-optimized(as a2a missile) rocket "pencil" of similar size.
There's a lot of sources saying it does have a ramjet, thta doesn't mean it's correct though I guess. Good sources are scarce. Most other sources say ramjet besides this (which is hardly a great source).
Yep, this PL-17/PL-21 naming controversy is indeed annoying.There's a lot of sources saying it does have a ramjet, thta doesn't mean it's correct though I guess. Good sources are scarce. Most other sources say ramjet besides this (which is hardly a great source).

The PL-21 (PL-XX) is an active radar-guided long range beyond-visual-range air-to-air missile develaminoapps.com
It's hugely unclear whether the PL-21 is even a separate missile to the PL-17.
Sorry, I thought the PL-17 name was only confused with PL-20 from the wiki article. 300mm diameter would give the AIM-174B ~30% more c/s area, so for an equivalent volume, the PL-17 would have to be ~6.25m long. At 250mm, it would need to be much longer. Less drag would help it though.
There are some estimation of MK 104 and MK72 performance from a Chinese study on the matter
I think it worth noting that we should compare RGM-66F with missile of the same period.
If you increase diameter by 14.3% (343mm vs 300mm), you increase cross-sectional area by 30.6%.
Astronautix has figures for the gross and unfuelled mass too.
That website is a godsend.400km is the touted range for the PL-21:
China’s New Fighter Jet Is a Problem for Australia
If the J/H-XX becomes operational later this decade, it will give the PLAAF the ability to undertake offensive counter-air operations directly against Australia’s air approaches north of Darwin.

Isn't that the same thing?
A dual pulse motor was used on the British Alarm anti radiation missile. Production of a reliable barrier, ie strong enough to survive the first burn but will disintegrate benignly when commanded is really difficult but not impossible.
Yep. A couple examples of true dual pulse would be SRAM, SM-3 upper stage, and PAC-3 MSE.

The simple and obvious approach would be to create a new mission symbol for 'multirole'. That could be 'B', using whatever weird logic was used for the launch environment symbol, though that might cause confusion among the hard-of-thinking with 'ABM' not meaning 'Anti-Ballistic Missile'. Or it could be 'M', with the existing-but-unusued 'M' for scientific measurements discontinued. Or some other letter; 'J' and 'Z' are completely free in both the missile and aircraft system.
Impressive, indeed!Four AIM-174s on the F/A-18? Very impressive if I say so myself.
