Having a problem with the deDaanan

[Taurec]

a tow sonar ? but if you look at a big sub like a typhoon .. there's enough room to place it.

[terran empire]

Tow sonar would cause problems as the primary array. and the Typhoon class as a conventional bow (dome shaped) the Dannan's bow though rounded comes to a point and has a large portion dedicated to the Flight deck and hanger bays which would take up a massive amount of space.

[HELLFIRE]

US Subs are the only subs I know of that use the bow sonar sphere,
largely because their primary mission was envisioned as ASW -- ref.
USS Tullibee. Since Danaan isn't really an ASW platform she wouldn't
need a bow sonar and could theoretically rely on, say, flank arrays
much like the British Trafalgar class.

Taking a page from radar technology, I'm also curious about the possibility
of a 'phased sonar array,' if it's even possible -- a bunch of inidividual
transmit / recieve modules interlinked into one big array.

Think more like 'The Abyss': If I use my lambda drive to create a negative pressure by lowering the density of the water front directly ahead/anywhere neer my sub, I would be able to "pull" it in any direction with little effort and great speed. I could also use such a theoretical devise to sense other pressure variences in the area, negating a need for any impressive sonar arrays.

...to which I'd reply: what exactly is the lambda driver? So far, the most
concrete response we've gotten is a BlackTech device able to form human
will into matter. Based on that GrendelPrime, part one of your argument is possible,
I'm not so sure of part two as -- at least by the anime standards --
we haven't seen the lambda driver able to form a functional DEVICE yet.

I think there are devices / techniques to check the local density of the
water... can't think of any off the top of my head

Every thing i have seen of the Lambda Drive indicates two possibilities

One the lambda drive could be a focused Gravity manipulator. The Drive would focus the gravitational field of the local environment to create a Wall of density preventing objects from impacting the host AS. it could also Boost the Mass of an object like a bullet to the point where in it's kinetic Energy would be magnified so instead of a small normal punch the round has a massive utterly Devastating punch. this could explain the speed of an LD geared AS. the Way Behemoth stayed together. and if focused enough the way gauron blew apart his victims with just a childish gesture of his hand

Possibility two the lambda driver could be a Focused Electro Magnetic Field generator. the field generated would have to be be a thousand fold that of an MRI. this would explain the light show displayed when it is activated. the pilot controls the intensity of the field for what ever they wish to do. Gravity and MAgnetics have some of the same properties there for my previous argument is the same for this one.

I don't think it's magnetic based ... ever held anything metal near a mri <g>


Lowering the density of the water ??

How would you influence water since water is well, very simple .. not much to tinker with on a atomic / subatomic level.

Second the Danaan is very silent,

So lets say you would create a "hole" in the water lesser density would make the rudders less usuable not to mention the cavitation you are going to get.

[GrendelPrime]

When you boil water your decreasing it's density, freezing increases its' density. Yep, phisics is cool.

Yea, I don't think it's magnetics either. Though They never actualy mention the materials that the AS's are made from and I presume that the Hardware is far more advanced than some copper wireing or fiberoptics. Possably wet-ware or some higher-tech level than our own. That said, I still doubt Magnetics would be a likely answer due to the adverse affects on the surrounding environment and nearby unshielded lifeforms.

I Think the most probable answer is Quantum field manipulation. Some undefined (yet undescovered?) energy harnesed and directed by the focus of select individuals with the aid of a "lambda driver". I don't think the writers know what it is. I would guess that given it's a Japanese Anime, that is hase something to do with the soul/heart of the manipulator. "Mystisism"... So this mechanism bends the water around the ship, increasing the density to the aft and lowering it to the bow, and in varying degrees for steering. The diveplanes and prop.s afore mentioned in the posts would be used for backups, 'don't go sky diving with out a reserve chute!', sucks if your Lambda Drive should fail for some reason.

Remember, they write/draw anime. Not the greatest at phisics or tactics. (total failure to understand U.S. undersea warfair. But I enjoy the story nun-the-less)

Dooooh .. i hear they cook eggs too with the LD ...
But really, I didn't see a trail of ice cubes behind the TDD-1 and no real steambubbles, imagine the IR signature you would get.

But i'll settle for the "undefined (yet undescovered?) energy " hey, works for me ..

[GrendelPrime]

I was just useing that as an analogy , I didn't realy want to get into the large amounts of space between the nucleus of the atom: its' electrons, its' protons and nutrons, not to mention it's the sub-particles. The spaces between these is varible in random particles at random times. If you should be able to make it hapen on a larger scale and direct it, the results would be fairly amazing. Well, not 'fairly'. What sort of power source is nessisary to power a LD? No idea. But I'm sure it could fry and egg at a 1000M with a spectacular light show and some cherry blossoms, No prob..

I don't know what relm of physics you studied, but water decreases in density both when it boils and when it freezes. Thats why ice floats on water.

Water is at maximum density at around 4 degs celsius. Below that, its density decreases.

H20 is weird as it does not follow the basic rules of chemistry and physics.

Oh, Yea. I forgot about the crystaline structure development. But it applies to most other substances and to a small degree water. Beond the more basic hot and cold analogy. Have you ever heard of the heavy water expariments in the mid 40's by Nazi Germany? Super Dense Water.

p.s. Easy expariment with hot water and died cold water will show the density thing. Just make sure you get the laminar flow down when you poor the cood water into the hot. Looks neat.

Ermm..

Heavy water is based on Duterium which is an isotope of Hydrogen. Nothing to do with its temperature. It allows the use of non-enriched uranium in nuclear reactions.

http://www.sno.phy.queensu.ca/sno/D2O.html

There is even heavier water based on Tritium, another isotope of hydrogen. a.ka. Tritium Dioxide

Laminar flow has nothing to do with mixing hot and cold. It's a fluid dynamics term that describes a fluid flow in which exists no turbulence. What you see is the variation in the refraction of light caused by the varying density of the hot and cold water. THe movement is caused by the convection of the 2 liquids of different temperature. The same effect can be viewed during a hot summer day as the heated air rises from the road surface, and interacts with the cooler air above it, causes variations in the refraction of light. The convection is turbulent flow, and not laminar at all.

In both cases the variation of density is miniscule, IIRC, since the refractivity index of materials is proportional to the square of its density, the visual effect is far greater.

Please do some more studying.

[GrendelPrime]

Umm... your mixing the subjects up a bit. I wasn't infering that Heavy water was any given temperature. That was just the little experiment when you mix clear tempid water in a tank, then poor in cold blue died water 'at a laminar flow'. then watch as the colder water sinks to the bottom of the tank'...

Absolutly nothing to do with Heavy water. Sorry for the confusion.
Thanks for the advise but I wasn't talking about that at all.
