submarine fighter

[VALKYRIE013]

all right.. been awhile since i've worked on something other than school work.. but now i've started on somthing that ihope will turn out well and be a part of a series..

ok.. i direct you to E M P I R E or wikipedia on the theory on supercavitation. supercavitation in a nutshell is mach speeds underwater threw a bubble of air and hydrogen rocket engines.. very interesting subject..

my own spin on the whole thing is a ring drive... think of a caterpiller drive (hunt for red october) and an ion drive. a supermagnet moving the water semi-silently , also the rings are movable for ultra-manuverablity

I've been working on a whole story for a couple of years on this idea, and hopefully i will be able to do something with it for a production.. maybe a game.. maybe

so..here ya go.. any questions welcome.. and also any coments

Well, it looks nice so far. This supercavitation sounds a lot like the underwater warp drive I once played with. The only problem with my version was that the bottom of the shell had to be open to allow water to flow in. If not, the sub had nothing to float on and it would race to the bottom of the ocean. Supersonic landings are not pretty.

What I like most about your design are the rings though they look a tad small to me. I don't get the feeling of an uberpowerful, supersonic propulsion system. On the other hand, making them too big would make the actual sub feel unimportant. Balancing is hard I guess.

Anyway, I'm going to read up on this supercavitating thing. Supersonic subs, really cool. And sound travels faster through water than through air, so supersonic is really supersonic here. Hmm, I wonder how high up in the air a supersonic sub could go if it breached the surface at full speed and straight up.

well the ring drive is just to get it up to 100kph and for silent drive.. then the hydrogen rockets in the rear end take over.. and the ends of the rings (in work) would still be in the water to support the craft in the air bubble ..

i'm doing this as a sort of prototype sub... with more advanced ( more complex as my modeling skills improve) up and coming..

thank you for the interest..


edit... wing stubys for aquanautics..(any in water space is prime space for sensors)
and but end details.. more on the rocket engines latter...barring school work (plenty of free timet his week)

any questions on the theory of supercavitation or ring drive just ask away.. i've done tons of research over the past....atlest 5 years..

[VALKYRIE013]

OKAY.. brainstorming on the offensive tech of this thing... according to the article.. the navy right now is developing supercavitating bullits for mine sweeping .. 50 cal, 20-30mm cannons... same as regular aircraft today... so thats an idea..
and of course.. torpedoes... internal? external? both.... might end up both.. larger variety being conformal.. and enternal torpedoes being the size of maybe a sidewinder.. or smaller
there's an episode of seaQuest that had lasers... might do some research.. but lasers in water o_O...

open to idea's on this... get creative..

[Dallidas]

Im pretty sure lasers in water wouldn't work to well.

as for internal or external torpedoes, i would think there would be too much drag in the initial speed build up to make it structuraly safe, but im no engineer

For supercavitation sub to move correctly, it should be aerodynamic. Basicly, use wings (or wing-style fuselage design) for underwater flight inside of gaseous bubble. As for ring-drive design... interesting idea.

[VALKYRIE013]

well.. aerodynamic in terms of a missle.. not an airplane with wings..the only wings she needs are stabilizers to keep her in the center of the air buble.. hence the small winglets on the rings....
this sub will still be a ballast system unlike the up and coming reverse wings on the up and coming designs on the board...
more updates today.. just got home from school...

[VALKYRIE013]

ok something fun... came up with an idea for the cannon... and still keep the hydrodynamics for hi speed

the cannon rotates in its holder.. and when its firing its open. but when its not its closed...

thinking something simalar for the torpedoes... a rotating system that rotates to closed when not in use... its something that might be a problem at high speeds..

[jack cloudy]

That looks cool. A problem might be the water it scoops up unless the cannon is stored inside the airbubble. (Which is probably not what you want because penetrating the bubble just to enter the water would waste a lot of kinetic energy.)

Let's see, apart from a form of torpedo, I don't see anything that is really a possible weapon underwater with the exception of fired singularities. (which are so out of place here it's not even funny.) And as for the high speed thing, the only solution I can find is to slow down first.

I have a similar problem in my universe where the ships use a form of innertialess propulsion system. The only weapon that can keep up and do damage is a large missile with the same kind of propulsion system. To avoid getting their flightpath messed up by conflicting thrust vectors, the ships come to a full stop, fire and zip off. I suppose it could be similar here.

Another solution I just thought of. Instead of launching forward, drop the torpedo out of the back. As long as it is faster than the firing sub, it can float out of the bubble and then accelerate towards its target. (taking an appropriate curve to avoid the tailpipe of the firing sub of course.) That way, the sub can continue moving at full speed and your problem would be solved, I think.

[VALKYRIE013]

whoops.. guess i didn't elaborate.. i have the rotation thingy as the answer to the high speed problem..so it doesn't need to slow down to launch internal torpedoes sorry.. need to complete my sentence >_>

and i am going to have atleast 1 rear firing weapon.. probably torpedo..(external) .. maybe 1 would be a cluster bomb... going at high speeds.. even hitting a BB would screwup your day...
