Competition: A modern medium AFV

[Khand-e]

Tentative announcement I may actually be withdrawing from this, I just don't really have the drawing or art software using skills to make anything that looks remotely decent.

I'm not a judge, but I assume you'll be judged on your design choices and the reasoning behind them, not shiny pictures.

[Collimatrix]

Yeah, the only thing Solidworks is nice for is that it gives a very convincing accounting of vehicle weight and size.

[Sturgeon]

Yeah, absolutely, just because I'm using SW doesn't mean nobody else should compete. For one thing, my submission is just one idea out of many, and I want to see what everyone else comes up with.

Having said that, Baberams now has (really bad) tracks and fenders:

 

Total weight right now is estimated at 34 tonnes. The tracks are shit because I couldn't find reference figures for Bradley tracks beyond the dimensions you see here, also because effort lol. As you can see, I have 7 roadwheels and one idler, which is a standard Brad roadwheel instead of a Bradley idler. The drive sprocket is supposed to be about the same size as the Bradley drive sprocket, although it may be better to use a new, bigger diameter sprocket.

[Collimatrix]

Conventional metal link tracks for a fast-moving military tracklayer should be 10% of the total weight or so IIRC.  Band tracks are somewhat lighter.

 

I'll try and put up a guide on how to do weight accounting.  Maybe this weekend.

[Sturgeon]

Well, Bradley tracks weigh whatever they will weigh given the individual components.

Point is, this tank will be well and truly coming up on the 38 tonne limit by the time I'm done. I'll throw out an estimate at the end that will be massaged, because the tank will be heavier in some respects than it should be, so I am going to hand-wave and say it evens out once I have a decent estimate in hand.

I am not sure if a bore evacuator is a great idea with an autocannon, but prepare yourself for the kawaii desu desu that is the 75mm caseless autocannon-armed Baberams:

Now available in Extremely Unconvincing Tan!

[LoooSeR]

Gun muzzle reference system may be blocked by bore evacuator.

Yeah, it probably is. I should fix it...

[Sturgeon]

Raised and improved the detail on the muzzle reference device:

[Sturgeon]

Now with side skirts!

 

Alright, current to-do list for the Baberams:

1. Finish the turret. It's currently just a box; it needs details like rangefinders, cupolas, etc.

2. Add a driver's hatch.

3. Add ERA

????

Profit!

[Sturgeon]

Updated my worksheet. Current overall weight estimate is standing at 34.64 tonnes. At this point, I feel pretty good about that, and am fixing the weight estimate at 35 tonnes. There's a lot of shit that needs to be added, but I also know for a fact that there are a ton of armor plates on the tank that don't need to be there and/or don't need to be as thick as they are (the hull box is, for example, literally 40mm all around, and there are no holes for the engine, suspension, etc like there should be). So, because effort is for suckers, the tank weighs 35 tonnes.

[Sturgeon]

This is about the rate of fire I'd like from that 75mm autocannon, BTW:

[Bronezhilet]

I have (properly) started:

[Bronezhilet]

Finalised-ish layout

[Bronezhilet]

And I forgot the transmission. I'm a genius.

[Vanagandr]

What applications are you guys using for design? I feel like one can do better than graphing paper in this modern era

 

Van should learn to read

[Bronezhilet]

Download Solidworks, I can give basis lessons.

[Toxn]

I use sketchup, because I am the worst.

[Bronezhilet]

Hmmm, I wonder what that could be...

[Bronezhilet]

Time to start work on the hull. 

[Bronezhilet]

Also, for those thinking "Wtf I will never be able to make something like that", it's made with the use of only a few SW base features: Extrude, Cut, Chamfer, Pattern and last but not least, Mirror.

 

Like I said before, I can teach whoever wants to learn SolidWorks the basis of the program. I don't know if I'm allowed to link torrents here, but they're out there. If you have SolidWorks and want to learn the basics, poke me on Teamspeak.

 

Also, since I'm providing the price, I won't be participating for the win. But if the judges somehow decide I should win, I'll give the prices to the person in second place.

[Bronezhilet]

I had forgotten how fucking broken the Mirror feature was, this took way longer than I wanted.

 

 

Also, making tracks is a disaster. I'll do that last.
