Vulcano is saboted, low drag-fin glide but I doubt it's RAP
Excalibur-A1 is far as I know only BB + fin-glide. RAP is to date talked about only.

You're correct -- I falsely recalled Vulcano as being rocket assisted, I must have crossed it with ERGM.
.... However, none of this takes away from the fact that the graphic of the round in the study shows rear fins which obviously are not designed to fold (of which is similar to the fin configuration of Vulcano).
Which leads me back to my hypothesis, that the round depicted in the graphic is meant to be saboted, and that the true diameter of the actual shell itself is likely a bit lower than 300mm, while 300mm likely would refer to the saboted diameter.
Your average 2S7 Pion round weighs 110 kg, and is about L/5 in length. The sheer dimension of this 300mm saboted shell is truly astonishing. Must have profound anti concrete capabilities

Don't forget a good part of the weight goes to the rocket propellant.
I was confused by this exchange initially.
Are we in agreement that the the 230kg weight of the "装药" means the explosive charge, or rather propelling charge of the artillery shell -- and it doesn't refer to the actual warhead weight of the munition?
Because the various terms used in that exchange to translate 装药 (explosive load versus weight of the explosives versus warhead size) makes me wonder if everyone was on the same page there.

Wait, now I'm confused. I thought "" means explosive charge, not propellant or warhead size, although many use warhead weight and explosives weight interchangeably.

It should mean the charge which moves the projectile, not the warhead in the projectile itself.
In context of artillery, it should refer to the charge that ignites (or explodes) behind the actual projectile, which propels the projectile to move out from the barrel.
At least, that's my interpretation of it based on the terminology in English of the relevant parts of an artillery shell and the translation of the Chinese words themselves.
Which sort of takes me back to the original question -- in terms of "" did you guys mean to refer to the propellant charge or the warhead weight in the projectile?

Ok, I see what you mean.
Here's the relevant section of the text in which the term "装药" appears:
本文研究的制导炮弹经历几个不同的飞行过程，首先从炮口以一定的速度发射，在某时刻火箭发动机点火，是炮弹的速度增加，发动机工作结束，炮弹开始减速，到达最高点后，设置2种不同的工况，一种鸭舵不张开无控飞行，另一种鸭舵张开以最大升阻比飞行。仿真初始条件为:初速 70m/s，制导炮弹重量为530kg，装药230kg，发射点地心纬度为 32°，地心方位角为 90°, 出炮口 10s后火箭发动机开始工作，工作时间持续 40s。
If I'm reading this correctly, the section describes the two different flight profiles of the shell. The two profiles are identical until the the shell reaches its highest point in the trajectory. Before the shell reaches the highest point, it's first fired from the artillery, which obviously requires propellant to push it clear of the barrel and then some ways along the parabola. At some point the rocket motor ignites and accelerates the shell further; the motor then cuts out; the shell continues onward and upward for a time when it reaches the highest point, after which it either enter a guided or unguided terminal phase depending whether control surfaces are deployed. The paper then lays out the initial conditions for the mathematical simulation: shell muzzle velocity = 70m/s, shell weight = 530kg, 装药 = 230kg, firing angle=90°, etc.
Given this context, I think "装药" means propellant charge, specifically the charge used to push the shell out of the barrel. I briefly thought it might mean the propellant (carried within the shell) for the rocket motor, but now I think it means just the external propellant use by the artillery piece.

I don't think there is a single case where 装药 would mean propellant charge as a noun despite what wiki page suggests. OTOH it almost exclusively refers to explosive in warhead (or demolition operation).
Also I don't see how explicitly set a number for propellant charge for an artillery shell would make sense as we all know tube artillery would adjust amount of propellant charge used based on the circumstance.
