BlackTailDefense Doesn't Know Shit About Tank Design

Link?

It was on a clip from what I presume to be Sparky's favorite movie, Pentagon Wars, though I can't seem to find it in my youtube history.

We all know Sparks is fond of advocating for continued upgrading of our M113s. I spotted this youtube comment the other day of an Iraq veteran giving his perspective on the matter: 

 

 

"We had one run over an IED, it ripped a five foot hole in the floor, peeling it back like a banana."

 

Is he sure it was an IED and not just a stray AP round from a DShKM or KPV?

 

(Or maybe it just ran over an already fired projectile that scraped on the floor.)

M1 Abrams vs M4A4 Sherman.

 

WHO WOULD WIN!?

 

 

 

Sherman has more firepower than the Abrams guise!

 

 

ABRAMS INFERIOUR BECAUSE IT HAS NO 5 MAN CREW

[Vanagandr]

Does he actually conclude that the Sherman is better?

[Jeeps_Guns_Tanks]

He rated it a draw.  It's pretty clear he doesn't know shit about the Sherman or Abrams.

This is the same retard who rated the Arjun better then the Abrams,

 

Of course he did.

[Vanagandr]

I guess, if we eliminate the metric of being physically capable of destroying or making an effective kill against the other tank, the Sherman might be capable of competing against the Abrams. Probably need to remove any metrics relating to vision too. It's not fair to compare the two if we consider the Abrams' fire control so we're gonna take that out too. Yeah, sounds like a draw to me.

Sherman is better than a tank with the Krautmetal 120mm?

Just think how it kicked the Tiger's and Panther's ass!

Yeah. Suck on that Wehraboos!

USA! USA! USA!

Makes sense, Sherman was better than Jagdtiger, which has pretty much the same gun as the Abrams.

[Walter_Sobchak]

The Sherman had five crew members while the Abrams only has four.  And since five is greater than four, obviously the Sherman is the better tank.  Duh!  

[Vanagandr]

A7V had 18 crew

Germany stronkest

I made an account only to comment and support that BRD is absolute retard. He is also a FURRY which is all you need to know to understand that he is absolute retard. ABSOLUTE FURRY RETARD. HOW THE FUCK ARE YOU GOING TO COMPARE SHERMAN WITH AN ABRAMS?

good first post, though you can compare the M4 to the Abrams but nobody with functioning cognition should come to his conclusion.

Article by BLACKTAIL

[DogDodger]

So who else checked to see if the M113 article was by the same author? Spoiler: it wasn't.

 

M113A3 was.

Well, that explains why there are entire paragraphs of buzzwords. That's not his first article there, either.

[Walter_Sobchak]

It's been six months since Blacktail posted a new video on youtube.  I hope he is doing ok.  We can't afford to lose such a rich resource of inadvertent humor.

Two loaders? According to his Failed tank series Ep. 19, 4 man turrets suck because if a gun needs two loaders, it needs a new gun.

"I'm going to design a huge-ass tank that dwarfs the Abrams and then talk about it like it is the best thing ever" 

Didn't he rail against tanks being giant?

A wankel engine for a tank is attractive on paper; like I said, three companies have tried it (although none made it work).  Turbines have improved a lot since the AGT-1500 and GTD-1250 series, but I think a turbocharged wankel would still enjoy a bit of an edge in specific fuel consumption.

 

I have just discovered this hillarious thread thanks to Alex bringing it back to live after four years. The discussion about Wankels is particularly interesting though. AFAIK not even those experimental Wankel diesels were able to produce reasonably more power than they consumed. Aside of other issues common to all Wankels the diesel one has another much bigger ones related to the chamber shape (it was partially mentioned here already). The first is that from its principle it can not achieve high enough compression ratio to work at all, i.e. it needs to be fed by a compressed air to even run. So you need either sort of two-stage Wankel where one works as a compressor or you need an external supercharger. The other is that the chamber shape is absolutely wrong for diesel (there is no solution for proper injectior position and therefore also the mixture formation) and you can't do anything about it. Both things combined mean that the efficiency of such engine is abysmal and at least in some of the experiemental engines it was in negative values. And now all the other issues of the Wankel design on top of that...

jesus christ, what a mental case.

 

145 mm smoothbore howitzer. Yeah, good luck hitting anything at all beyond 15 meters.

 

Came across another mad cunt while searching.

FWIW, the Rolls Royce Wankel Diesel was actually built.
 

There were, as I mentioned, a few others.

Yes, I know. Though the Curtiss Wright one was not a real diesel. It burned diesel but it used spark ignition. 

 

Anyway, You are right, this last RR prototype looks to be really functional one (though the actual fuel consumption, reliability and durability is questionable as it looks like no testing was ever done or at least there is no info about it available). I learned that the development in Rolls Royce was stopped when the company went bankrupt and was briefly restarted when it was nationalized but soon again stopped. One can only guess that there was a reason why they didn't continue.
