Gun, at some point, every tank manufacturer was not a tank manufacturer. There's always a first design for a company, and there have been several times when these first designs were good. EE-T1 Osorio comes to mind, for its goal (cheap reasonably modern tank for third world nations on a 40t weight limit) it was a fantastic design from a firm with no previous tank work, in a country with no tank industry.
I second the Osorio, was a surprisingly well made tank despite no prior experience making MBTs from Engesa; just wheeled death traps. I would personally have loved to see what would have happened if someone (Saudi Arabia probably, maybe Thailand or Indonesia too) did buy the Osorio and Engesa didn't go bankrupt.

Welcome to SH!
Personally I love the Obj. 640, it's quite the innovative design (at least, if it works as advertised, which is always and adventure when talking about prototypes and test beds). But some of the things you mentioned I don't think would help.
9 hours ago, ro1994 said:put Commander and Gunner inside the free space inside a turret basket, with crew capsule around it, and make all of them sit below the hull line. It would also decrease the chance of the one-penetration crew massacre.
Yes, sure, this is indeed a solution to a problem. But how much of a problem is it? Often times, when a vehicle is penetrated, comparatively few crew become casualties, as described here. (just click the text and it will take you to another site, where I got my info).

The biggest threat to a "complete crew kill" would be a catastrophic ammo explosion, but since the ammo is separated, there's not a lot of threat from that. In general, placing crew below the turret line would be a better solution that separating out the crew, rather than with some within a crew capsule and some outside (this might cause resentment and animosity from the crew placed outside the capsule, as the capsule obviously has better protection).
9 hours ago, ro1994 said:As far as I can remember, one of the major disadvantage of it is lacks of "Mk1 eyeball-style" surveillance capability, the commander cannot see much peeking through the periscope as the FOV is very limited, and then-use-only-panoramic-sight solution isn't the best option for maximum situational awareness...but that might be solved by redesigning it so that other parts of the tank doesn't block its FOV as much as it was (although it may increase profile of the tank), or one can supplement it with the fiberscopes that would not require as much area as adding more rigid and bigger-than-normal (since crew sits inside the hull, or nearly, in case of the real Obj.640) periscopes
It could also be supplemented by surveillance system similar to Israeli IronVision
this is exactly the problem products like "Iron Vision" are trying to solve. No matter how many periscopes you place around the tank, you will never have as much situational awareness as if you just stick your head out a hatch, without possibly compromising the armor of said tank. With Iron Vision, and similar products, you don't even need your crew in the vehicle (so long as you can keep a secure connection), but it's probably better to keep them in (some of) the tanks. And as you said, this would negate the problems with having all your crew in the hull (though, purportedly, the Armata doesn't have bad situational awareness).
9 hours ago, ro1994 said:Also, I think the basket/capsule could be designed to be "disconnected" from the turret (with another pair of hatches), hence it may have higher chance for the crew to survive the top-attack ATGMs (as they need to go through a lot of things inside the turret, including the empty space - thus creating more distance, which is important to be optimum for the shaped charges to be effective, and the crew has another layer of "basket's roof" protection)
Hmmm, so they have to open a hatch to get into the turret space, then another hatch to get outside? That sounds like a little to much work.
If I were to make a design, I would make the tank similar to the Merkava (front engine, rear crew space). With the introduction of the Mark 4, the front hull armor is quite good yet doesn't impede maintenance of the engine, while the rear compartment places the crew as far away from enemy gunfire as possible (whilst still remaining within the tank). The turret would be unmanned, with a bustle loader, launcher based APS (Iron Fist, more specifically), autocannon resistant (lets say resists 25mm M791 from the M242 at 250m), and placed upon the hull roof, separated from the crew. All 4 crew (commander, gunner, driver, robotic wingman operator*) would be in the hull, just below the turret (with the turret mass generally covering the crew from above), and equip them with an under armor surveillance system (i.e. Iron Vision).
* The "robotic wingman operator" would be a crew member who manages (and possibly controls, if armed) the various unmanned ground, aerial, and (if applicable) floating/submerged vehicles that assist the tank in battle.

Ah, but who will administer it?
And what will this doctor do after the purge?
Perhaps the patient needs a firm hand and constant guidance to prevent a relapse...
Obviously our god emperor, Trump!
But this is always a good question, as humans naturally try to destroy themselves... or at least benefit themselves in the short term and completely disregard any long term consequences.
Perhaps a more fibrous diet, like a term limit for the House of Representatives (and possibly the Senate as well), to keep things fresh and moving? A way to screen a candidate for their ability to think critically and compromise would also be a welcome change.
Just spitballing ideas.

As referenced several (3?) times on this thread: Washington DC needs a hearty, Stalin-era purging, of almost everyone on both sides, and replacement by people who are willing to cooperate, not just earn their pay check and squabble like retards with microphones. I would think of this as a political laxative, as both remove large amounts of shit and ease the pain of the guts of our political machine, making it more efficient, as well as more comfortable for all involved.

I see that the BMP-2's apds rounds are limited to one belt. Any guesses as to whether the German 20mm guns will get the same treatment?
Still waiting on German 37mm AA guns getting their APCR, like the Ju 87 Gs.

For what it's worth it seems more like that the A4 upgrade is being scaled back instead of simply being cut. Removing the future growth perhaps?
When you put it that way, the Bradley sounds like a tumor... which I won’t argue against.

That handguard is rather long. It could be made of injection-molded plastic, but injection molding something that long while still holding good dimensional tolerances is challenging. The mold halves have to close exactly on the part. Those mold halves would be something on the order of 300mm long. At that length, slight differences in temperature between the mold halves are enough to cause distortion and misalignment due to differential thermal expansion.
This might be stupid, but couldn’t you make that 300mm long handguard in 3x 100mm long pieces and fuse them together? It might not look pretty, but it should get the job done without having to worry to much about warping.

I upgraded my Shot mk-1 to Shot mk-2... I now need to make a new gun, but still:
18.11kg complete shell, 800mm total length, and now has a 130mm bottle shape.
New propellant mass: 5.25kg
New velocity: 1207 m/s out the barrel (with 50 caliber barrel).
projectile is the same as before (5.84kg complete, 275mm length, 50x200mm tungsten carbide slug)
I'm getting penetration values that I believe are a little high (173mm @ 2000m @ 0o), but then again my shell is going hella fast, so IDK.
After doing some research, and some better math, I found different numbers for my shell’s penetration. Using this formula:
E= energy of projectile
A= armor resistance factor (1960 for tungsten carbide against 240bhn armor steel)
D= Diameter of penetrator (in decimeters)
S= armor thickness
And solved for S, you get an equation that will give you a penetration figure for your shell that’s close to RL (I tested 90mm M304 and 76mm M93 and came out to 322mm (12.68 inches) and 235mm (9.25 inches) at PB, respectively). Using this and the data I got from JBM and the load calculator for my projectile, I am now getting numbers that look like:
point blank:
447mm @ 0*
335mm @ 30*
2000m:
232mm @ 0*
174mm @ 30*
I am now pondering how I made a weapon so poweful by mistake, but then again my shell is over 1kg heavier, and moving about 200m/s faster, that M304, so I guess it makes sense that my shell would penetrate more armor.

Interesting threads by a WT user to try and calculate realistic shell performance:
https://forum.warthunder.com/index.php?/topic/418496-realistic-88mm-kwkpak-43-apcbc-performance/
There's a couple more, too. Any truth behind all this effort, @Bronezhilet?

End date for posting your design is 30 sept, about 2 weeks left. Are those events something serious?
The things that are/have been happening, I couldn’t care less about... but someone else does care, so it’s my fucking problem now.
The things that are going to happen are going to be serious though, I just need to work up the courage... whenever the hell that will be (I’m quite timid /reserved /introverted IRL).
On top of that, I feel like I’ve hit the ground emotionally, and have lost a lot of motivation over the past months. Coupled with all the stress from the other bullshit, I feel pretty low RN.
...

...
Point is, it would take a damn miracle for me to complete my vehicle by the end of September... in my opinion. As much as I want to do this, I can’t make my vehicle and figure out my life shit at the same time; and even though I desire this project above my IRL responsibilities, I have to focus on my life.
Good luck, Lord James

I don’t think I will be able to complete my vehicle, with all the stuff that’s happening (and about to happen) in my life. Kind of a shame; this is the first time in a while that I actually felt a desire to do something... oh well.

"It's shit, just less shit than the others".
This was my point.
Is shattered, fine china (WT) any better than polished garbage (WoT)? Because I’m pretty sure both are worthless and should be placed in the trash. Gaijin ruined their own game, for me, by making to many business decisions at the expense of player enjoyment. They’re comparable to EA in my eyes, and will therefore be ignored (and ridiculed) by me until changes are implemented.

Jim, buddy, pal. Wow.
Also, the fact that his net worth is 50 million dollars MORE than Bill Mahr's, and he's squawking about Socialism? Yeeahh.... Sure, buddy. Sure.
Hmmm. Doing a little math, if Jim Carrey were to relinquish 2/3 of his net worth ($100 mil),
he could effectively double the average income of almost 125,000 Venezuelans for a whole year... except we we all know rich socialists never actually practice socialism, so this would never happen.Edit: whoops, late night/hungry posting is not in my best interest. I mistook the average salary for average daily wage. Recalculating, he could double the monthly salary ($1.61 [April of this year] to $3.2) of over 5 million Venezuelans (~5,175,000, if my math is correct this time) for a whole year, or roughly 1/6th of the entire population of Venezuela…
