MBT

I have an MBT project going. Any criticism and suggestions from the community at large would be good. Still considering a material for the turbine to made out of.

Take a look at what comparable turbines use, and WHY they use it. That's the best advice that you could get, for turbines.

Well why not post the whole tank description over here?

Because I cann easily modify it on google docs, and it's what I use instead of MS word because it hosts them online.

I'll reply here rather then in PM, to boost V10's esteem.

Your APU is an electric motor? That doesn't work on any level.

Perhaps you mean hydrostatic or hydrodynamic?

Unprepared fording depth should not exceed your turret roof height. It should be a fair bit lower then that actually.

Your speeds. They are absurd.

There really is no reason to use a gas turbine as the primary engine in a tank which is driven by mechanical transmission. Perhaps with an all electric drive, but not mechanical in any way.

And aside from that, I can think of 30 year old military multifuel diesels which are better in every way then any modern gas turbine that would be put in a tank.

I'm no GT design expert, but I'm pretty sure you have two useless recuperators, as only one will actually help.

By the way, speed in a tracked vehicle is really limited by track strength (Which you can't improve on much from RL), and the fact that when you move them fast they "balloon", tearing themselves off the wheels. In MT, you can't get away from this, and therefore can't really increase speeds much.

As for battery charge time, I think you underestimate the ammount of juice needed to run the systems on your tank. Grossly underestimate.

This just asks for trouble.

Your first layer of armour won't work, especially not on HEAT rounds. By the time energy has transfered in a "wave" around the plate, the AP or HEAT penetrator has bored through. This is especially so since AP rounds since 1921 have been designed to concentrate as much of their energy as possible on a single, small point.

This makes no sense.
Chobham = layered plates of ceramics and metals.

Also, you seem to have no structural element, as exote isn't structural. And really, if it got through the DU mesh, the exote won't help much unless it's real thick.

Spall liners do not a quiet vehicle make.

Also, where is your ammo and fuel stored to be able to have blow off pannels? It's nice to say it has it, but there are very few places they can actually be.

Where are you fitting your huge APS missiles?

Actually your whole APS and armour scheme isn't realistic.

7m rule, you brokes it.

I don't think your autoloader works. Revolver autoloaders have poor capacity, and this robotic arm thing doesn't seem like a workable idea in the cramped confines of a tank, where the rest of your rounds will be spread around in small groups in akward places.

Thanks.

I actually heard that the French Leclerc uses a similar autoloader, so that's why I used it. Could be potentially ludicrous and wrong. I'll look into that some more.

*facepalm* I forgot to log in.

I need a lot of help with the armor. Anyone have suggestions? I want this to be protected with at least three layers designed to handle most any projectile. I am doing some reading, but suggestions on improvement would be nice.

Protection from "most any' projectile, means weight. There's a reason the MCA-7 exceeds 80 tonnes, despite very cramped internal space. A big, heavy reason.

The Leclerc's autoloader needs to be manually reloaded from the hull magazine. There is no special arm that does it.

Only the front can be armoured against MBT guns anyway. I'm not sure about designing your own armour scheme, because it will probably not work and the improvement over RL stuff won't make much functional difference to how good it is.

Yeah.

My inability to design a good enough own armor scheme is one of the things that hold me back from entering tank design. Although I have certain ideas, but I'm unsure about their viability ::pokes Nianacio::, and then containing costs is very difficult if I try to achieve results.

Worse than just cost in dollars is using limited non-renewable resources, where the more of it you need, the more it costs, i.e. massive diseconomies of scale occur. If working with well available, positive economy of scale resources, using processes that can be well automated, the possibilities of armor improvement in MT vs. RLT are or at least appear to be very marginal. We're not talking twice better armors, more like 15%, 20%, 25%, maybe 30% gains.

I'll keep looking. I've got some ideas myself. As for weight, I'm not particularly worried. Since I field the MCA-7 anyway, my army would be equipped to deal with such a big tank. I've also ensures bridges were up to standard as well.

If you field the MCA-7, you already have the role of a high-end, heavy, high-capability tank filled. I don't see why you'd need to supplement it with a less capable heavy tank. I'd rather add a medium one to the mix.

This isn't exactly true when you're looking at overall protective capability, rather then protective material depth. And I realise you may try to argue this, so if you do just PM your concern so we can clear up the meaning right away rather then have 50 pages of increasingly longer posts that I don't have the time to keep up with. Although I'm hoping you understand what I mean when I say protective capability and not protective material depth, aka armour thickness.

Sumer's tank is very capable, and I'll purchase every new DPR he has available for the newest model. I am mainly trying this because I want to know that I can design a successful tank.

I like your idea though, and I'll call it a medium and change the stats.

I have had Firefox, IE, and Google chrome downloaded onto my computer for a while now with no problem. Recently I downloaded YIM and now Firefox doesn't start up. If I restart my computer a few times, and try to open it a few dozen times each time I restart, it will eventually pop up. How do I fix it? Chrome and IE still work fine but I prefer Firefox..

I have two computers: I call one the "good" computer -- it has two monitors. The other is my "junk" computer with one screen where I download a lot of stuff to it.. . If I wanted to continue using both computers but only with the dual monitors, what would I need to buy? Is there some sort of splitter I can buy that will allow me to switch between each CPU? Where can I buy one if it does in fact exist? Will I still be able to use one mouse and keyboard?.
