Take note of the tilt

[johnno74]

Hahaha thats a great vid. Brings a whole new genre to SH3

I like.

[Huskalar]

That was a lot of fun to watch. But the tilting is too much in my opinion.

[HunterICX]

I've seen the movie before
but it stays a funny classic :rotfl:
especially that jump is priceless!
and the music suits the movie very well

[Cezbor]

Funny and has nothing to do with realism Maybe that's why it's still interesting:hmm:

[XLjedi]

That was funny...

So what control surface would allow the sub to barrel roll in the water like that? ...I mean that we would have any control of?

...and is the tilt in the proper direction? I would think that a strike below the waterline would be below the CG and (if anything) would cause the ship to tilt into the impact?

[andylegate]

Maybe I'm being nit-picky here but:

Ships don't "tilt" .......

They "List" or they "Roll" (unless it's the bow or stern is going up and down, then it's "Pitch").

[XLjedi]

An excellent point!

I'm just going to assume there was a pinball machine on board...

[andylegate]

Actually, the reason the ship rolled so far to starboard was PO3 Bubba ran from port to starboard when the torp hit. His 450 lbs did it.

[jazman]

Even my girls liked that version of SH3.

@ Venatore

Seriously though, the roll, is it in the wrong direction?

Assuming waterline represents CG... I wonder, is that a fact, or am I just conjuring math notions...

Matey, I woulden't have a bloody clue about the physics of a torpedo hitting a ship, I'm an Infantry Soldier in the Australian Army by trade so my knowledge is ........ "crap" in this area . I was hoping I could supply the footage and someone with naval/modding knowledge in this area, would able say "yep I see what your getting at, with the tilt, list, role etc.

I'm still holding my breath

Ven.

[XLjedi]

On the side impact, I dunno either...

I guess I should just assume the physics model they have in place is correct.

I've always liked how underkeel detonations kinda pull the boat down before it bobs back up. Smaller ships do rock a bit on impact, don't they?

What exactly are you suggesting then? (if anything) ...maybe adding a little roll (or more roll) to impacts on the larger ships?

[Blacklight]

I'd say.. look at the immense speed the Uboat is travelling and the torpedos that zips out is going a crapload faster than it. I have a feeling that it has something to do with the torpedo hitting the boat at a few hundred mph ! I think it's the game's physics system trying to deal with that.

So what control surface would allow the sub to barrel roll in the water like that? ...I mean that we would have any control of?

I have no clue. I've been trying to barrel roll my Uboat ever since I saw this video a long time back with no success. I suspect that the video was either edited at that part to make it look like it's spinning, or he did an out of control crash dive somehow that spiriled his sub into the depths.

That was friggin brilliant.

Okay,

I was a Tin Can sailor while in the Navy (1984 - 1994). I served on board the USS Preble (DDG-46), USS Coontz (DDG-40), and the USS MacDonough (DDG-39).
These class destroyers were 513 feet long and 53 feet wide at the widest beam, draft of almost 18 feet (5.4 meters) and they displaced about 5,600 tons.



These ships were not designed to roll past 52 degrees. As a matter of fact, my radar antenna (AN/SPS-48C), was the 2nd highest object on the masts. It weighed about 2 1/2 tons (it was a phased array attenna, quite large made out of wave guide stacked up, looks like a large rectangle) and was designed to shear off if the ship ever rolled passed that 52 point, so that the center of gravity would shift and allow the ship to go up right again.
If my ships had rolled over as far as the one in the video, that would have been all she wrote! My ships would have continued to roll until captsised at that point.

I don't know how far she would have heaved over from a torp hit (thank god I never had to find that out!), but I'm sure that it can be figured out.
One would need to know the amount of energy release from the torp, angle of impact, depth of impact from the water line, and where along the length of the hull the torp hit (if it was in the stern or bow, the ship would be shoved over and wouldn't roll).
I can tell you right now that a torp hit on my class of destroyer in the same area as the movie, would not cause the ship to go up in a fire ball, but would have opened up the #2 boiler room to the sea.

Most modern day weapons are designed to penatrate, then detonate. I used to teach the Harpoon Cruise missle (RGM-84D) and that is how they work. Many of today's modern torpedos don't actually impact with the hull, but instead dip below the keel and then detonate.........with enough energy to lift the middle of the ship out of the water, breaking her back.
If our modern ones can do that (with over 5,600 tons) I imagine that an actual side impact that's shallow would damn near push the ship over!
