[REL] Realistic Torpedo Trails

[Oby]

SH5 has lot of things that they disturb me and one of them were torpedoes ...I must say that in SH5 we have best torpedo models ever,but they still can't compare with what Hans did.I manage to port them in SH5...And it looks great...

1.HAHD torpedo models and textures for SH5.
2.Electric torpedo trails completely reworked to be more realistic.
3.Air trails extended and also more what they should be.
4.File is compatible with excellent TDW FX mod(version 0.5) and is JSGME ready.

This mod is based on excellent HAHD Torpedo mod made from Hans Witteman for SH3.Check his tread in SH3 mod workshop.You'll be surprise what he had done already.:rock:

Trails only:http://www.filefront.com/17474601/Torpedo_Mod_v0.1.rar

Complete mod:http://www.filefront.com/17478703/Torpedo_Mod_v1.0beta.rar
-this version is still in beta stage,so be gentle with critisism.
-known problems(beside the official one-like magnetic pistol don't work...):
1.Torpedoes are blurry underwater.
2.Ejecting from torpedo tube to fast.
3.Torpedoes can't be seen from air.

I'll post some more screenshots later...

P.S: Sorry for my poor English...

Splendid mod! Compatible with TDW FX mod(version 0.5)? Great! Thank you very much!:up:

1.Electric torpedo trails completely reworked to be more realisticelectrically powered torpedoes have no trails...at least it seems logical to me ... where they are to come from??:o

only gas or steam-powered torpedoes have a bubble-train

Ach... I have tested now this mod and... I looked forward to the mod with a new wave behind the torpedo, but in this mod is regulated a bubble-train (my mistake).

Olzeen, you´re right, it is not realistic.


@ josef....

2 Olzeeen: I know. It was a compliment, that this mod is compatabile with TDW FX mod. I use wamphyris62 great "no torp bubbles" mod, but I thought that someone created a wave behind the torpedo... I was looking forward too soon...

[quad5]

Oby The trails should be longer and wider, can make?

[tonschk]

:salute:Thank you :DL Oby :up: the stock torpedo trails are awful

[Oby]

New stuff on first post...Hope you'll like it...:salute:

[charognard]

Ok Oby thx, but, do your mod remove Electric torpedo trails ?????
Or must I install " remove eltric torpedo trails " mod after yours ?

[Oby]

@ josef

It is meant to represent a fast faded cavitation E-torpedo trail...Just not exactly authenthic...Need to implement new texture for it...

[Oby]

This mod is NOT compatible with Wamphyries mod...You can't use both...It is as it is...:salute:

[Oby]

...but they are longer...It can be done for sure...But need to solve primary bugs first...

[quad5]

Excuse, with long everything is all right. Has cleaned TexturesTorpedoMod1.0 and the trace became wide and long.

[Olzeen]

cavitation occurs under pressure .. ... this is ridiculous .... any electrically powered torpedoes!! have no tracks .....

lol oby...not exactly authentic???? .....cavitation on torpedoes...low weight and lower deepness....lol
read wiki and let....:haha::har:

would be this torpedo 400000kg weight and 500 meters deep, there would cavitation ....

You sure know that cavitation is not dependant on weight? And depth does REDUCE the possibility of cavitation, since the boiling temperature is rising with depth. I would not laugh at others and then shame yourself.

Effects that support cavitation on torpedoes: high speed (not the torpedo itself, but its propeller), low depth.

So, exuse me for: :har:

Thanks KarlKoch:salute:

I did not want to laugh at oby personally .:oops:.sry oby.... I've only laughed at the fact that he "referred not historically exact ..... the first torpedo used in which cavitation was first built in 1977th
so that the topic should be done now but ...
I hope you can understand what I write .. I have to say what I want to write a translation program .. sry


"In the military field torpedoes are used, moving at high speed under water in an artificial cavity. This technology was first developed by the Russian navy to the application stage and the term is supercavitation known.
The speed of forming a super-cavitation in water is in the range of 180 km / h, depending on the pressure and the temperature of the water and the shape of the cavitator. First, a functioning system that uses the supercavitation, 1977, the torpedo Schkwal after ten years of development by the Navy of the Soviet Union was put into service. Its speed is specified with 350 to 500 km / hr. It is driven by a solid rocket motor.

One problem with the motion in a super-cavitation is the controllability, the early models of Schkwal were uncontrolled. There were, however, since different control concepts developed rotate, so current versions of the Schkwal probably around its longitudinal axis and are controlled by means of a hinged axis cavitator.

The German Navy has in common with the technology company Diehl BGT Defence is developing a new high-speed torpedo (Superkavitationstorpedo). The torpedo is specified by the manufacturer under water, not only over 400 km / h (about 216 knots), but still manageable."

...Yeah...But super cavitation - that's entirely different subject...I was writting about propeller cavitation that is caused by the speed and design of ww2 toerpedo propellers...:salute:Mybe somebody with more knowledge of English language will find different word for that effect...

[KarlKoch]

It is the correct word for that. Its called cavitation. What Olzeen is referring to is based on the same effect, just in a larger scale. He is right when he says it was developed sometime in the 1970's. However, cavitation as a hazardous side-effect was known to be present in WWII technology.

Yes, you are absolutely right on that. However, cavitation is also present in high-speed movement scenarios in viscous fluids. It happens when the movement is fast enough to cause the fluid to boil, because of friction. Bubbles are generated by that and they will explode shortly after, causing noise and mechanical forces. Mechanical forces can destroy a propeller in pretty short time, while the noise can be heard for very long distances underwater.

that's absolutely right .... you are right ... I just can not imagine it in the second world war as a side effect cavitation torpedoes produced ....
the enemy would have to see her and was very easy to listen to .... these effects to be prevented at that time ...
I still think the bubbles formed during cavitation no trace, since the bubbles then collapse into itself, while cool (condensed) and no traces left behind ....


again sorry to you oby .....:oops:
I hope you're not angry with me

[Oby]

No I'm not angry...:DL

KarlKoch,what is your opinion on e-trails? Should they be removed as Olzeen said or not?

[KarlKoch]

I didn't look at the Mod, yet. But they should not be visible at the surface, as cavitation is a very short-term process and the bubbles should not last long enough to reach the surface, even at very shallow depths.

[Bill Nichols]

This is screw cavitation:

http://www.originalpropshop.com.au/Images/cavitation.jpg

http://www.originalpropshop.com.au/Images/pitch.jpg

Cavitation occurs when the pressure on the forward face of the propeller blade becomes low enough that vapor bubbles form and the water boils. As the vapor bubbles pass over the blade face and move away from the low pressure area, they collapse. The collapsing of the vapor bubbles might seem trivial, but it is a very violent event which can result in the pitting of the propeller surface. Cavitation is a major source of propeller damage, vibration, noise, and loss of performance. Cavitation can be caused by nicks in the leading edge, bent blades, too much cup or simply high boat speed.


Whether or not screw cavitation occurs depends on: the shape and size of the screw, the speed at which it is turning, and how deep the screw is in the water.

To avoid generating cavitation-induced noise, modern submarines have large, slowly rotating screws and avoid high speed operations at shallow depths.

:know:

[Oby]

Thank you Bill and KarlKoch - this is exactly what the mod is trying to represent...:salute:

[Olzeen]

Does this mean that do you remove the e-trails?? the bubbles will collapse they are no longer visible after a few milliseconds..... so do not rise to the surface ... do not forget torpedoes have two screws that rotate against each other ..

Not really...
In american submarine - yes, but this is "real Hollywood true".
In real whole air which push torpedo into water was pushed to uboat (to hide uboat position).

Don't trust amercian Hollywood effects!
