Crap pile one: CoP/CoG relationship OVERRULED by type of control (active or passive) system used by rocckitt;
Crap pile two: Geoff clearly wrote the Saturn V had NO FINS!
Whatever rubbish you claim, the CoP/CoG relationship is certainly OVERRULED by dynamic control - look at all the references I gave you! - Oops, sorry, I should have realised that you can't read!
NO rocket can ever have any aerodynamic stability until it is moving, fins of NOT.
Still, we can hardly expect any knowledge of "Rocket Science" from a mere Attack Terrier!
The important point is still that large space-rockets (
they do get up your nose don't they )
do not rely on fins or aerodynamic stability during normal ascent - especially as recent ones do not have any fins at all!
In case you missed it the first two times:The Saturn went up stabilised
WITHOUT the assistance aerodynamic fins! The "aerodynamic fins" played no part in the normal ascent. Do I need to say it more?
Get over it! Large rockets do not rely on "aerodynamic stability", and "
Most large rockets, in fact, become unstable as speed increases. The control system typically works hardest in the stratosphere, where the rocket is at high speed in air that is still fairly thick, and where winds are often strong. They go back to being neutrally stable as the air thins out and aerodynamic forces become insignificant."
Surely even the Puppies attack Terrier can see that when the
rocket has no vertical velocity there simply can be no
aerodynamic stability.
Sorry, I know that's a stupid question! You haven't the slightest idea what "dynamic stability" means.
Whatever the TotalIdiot and his boss Puppy say, the
Delta Rockets went up,
Saturn Rockets went up, the
Ariane Rockets went up and the
Space-X Rockets went up without relying on aerodynamic fins for stability!
The Delta rocket family and Delta IV Heavy launch - look real hard and you will find "Look Ma no FINS!" - neat and sleek without fins aren't they?
Ever checked how many fins on the Falcon 9 in this post!
Carefully
count all the fins on the Falcon 9 while you avidly watch every second of this launch!

I wonder why it didn't fall over, not even when landing back on the barge! Maybe it relied entirely on yes
dynamic stability! What about discussing the material and not trying to score points nit-picking about little errors?
Yes, I know that neither the strangely absent chief Puppy nor his attack (Grr!) Terrier have any idea about "rocket science" to discuss, so all you can do is nit-pick.
The real Puppie has proved he knows nothing with his seemingly endless repetitions of his latest long-past-use-by-date Copy Pasta - Yuk!
Go crawl back into your kennel until your master comes home
Have a nice day counting fins on modern rockets!
Bye, bye.
