The Tanks of YOH - Tank Design & Theory

Let us know which faults you have spotted in those tanks! ✌️ Do you want to hear Ed's rant about the issues in those tanks as a follow-up video? Please vote on whether we should make that vid. www.strawpoll.me/20967894

Without making too long a list, it seems like the YOH design team had generally acquainted themselves with the design principles of tanks, but that they didn't have knowledge or appreciation for certain design elements that had already been tried and failed, or those few that were found useful, but had since become outdated. Some of the elements (such as the mine flails and the walking feet) seem to be ideas from people with absolutely no military experience whatsoever. They were also guilty of the classic engineer's blunder, developing interesting systems that added complexity and cost out of all proportion to the claimed benefit. It's amazing to me that they tried so many things to shuffle weight and ammunition around, with sensible goals like balancing the gun, increasing the ready rounds, and protecting the crew, but rather than settling on putting the ammo in the turret bustle in even one of their designs.... they decided to put the entire engine up there instead. ಠ_ಠ

Putting an engine in the turret presents a whole host of problems, especially if mechanical coupling is used to transmit the power, as opposed to electro-motive drive. Even if electro-motive drive was selected, it would represent a significant rotating mass and the turret would necessarily be able to turn faster in one direction than the other. It would eliminate the degree of isolation from a source of vibration that the gun and its attendant optics enjoy by being mounted to a separate structure, just like an ordinary pick-up truck will ride better than even modern luxury cars because it enjoys body-on-frame construction which has been abandoned for cars entirely. Putting the engine in the turret would also probably render manual traverse either impossible or unreasonably difficult, or slow, or both. It just seems a stupid way to balance the turret compared to putting literally every other piece of possible equipment into that space to balance out the gun, everything from the radios to the coffee pot, and letting the engine be in its proper place in the hull. Let us not even say anything about the difficulties that would arise from transmitting the power mechanically to the drive...

I love the old 1950s-60s style of these tanks, while some ideas were super bizarre, not all their ideas went to waste. The ammunition fire funnel system lives on with our blowout panels.

My main question about these designs (particularly 5-7) is what the actual hell was going on in this design process

When all the world of tanks blitz ppl are watching this video

I know that I'm probably being effected by my upbringing in the US during the 1950s-60s, but it looks like the Yoh company was doing designs for Matel, HASBRO, and several other toy companies for the toy tanks we played with.

I once worked for HL Yoh. I had no idea they had done this.

The ingenous idea of engine in the turret should be augmented by putting main gun in the body of the tank. When tank would need to pivot fast to acquire target, small legs would come out on sides, rotating whole tanks fast.

A 105mm revolver cannon? I'd love to see somebody actually make one.

You've got yourself a new subscriber here, this was fascinating. I imagine the 'drawing board' consisted of a few pencils, 1/5 of a Reem of paper and every known drug available at the time. No.7 is hilarious 🤣, just ...why?...

There's really no one who knows Flawed Tank design like the British, Its in their DNA..

Short hulls and long guns . . . a recipe for the WoT pole vault event.

Wait... WHERE ARE THE HATCHES?!

Although none of those designs became reality (for obvious reasons), it is still important that someone made the design and thought about it. Improvement is only made by questioning the established.

I think I had an aneurysm on the last one.... Engine in the turret and without an electric drive so mechanical power transfer to gearbox... X_X

WoT Blitz gonna add this to the game. So, get ready for new views!

From a basic operational & maintenance standpoint, putting the engine above everything else almost ensures that everything will have oil on it eventually. Like, everything. Or fuel. Or both. Probably both. And water. basically, the crew would be swimming in filth after a hundred hours of operation. From a safety standpoint....a rollover would be cataclysmic for most of these tanks. There's no way to get the crew out of the oscillating turret should their hatch get jammed up. They would literally have to cut them out. These things all look like deathtraps for at least half the crew, frankly. I love that the loader in that one abominable tank is handing shells up to the gunner blindly and hoping he doesn't drop it back down on his foot. Don't think it wouldn't happen, it would absolutely happen. From an ergonomic standpoint...none of those look even slightly comfortable. And boy would it suck to be sitting in front of the engine up in the one turret--boiling while the driver freezes down below--or vice versa. "Sir, can I turn on the heat?" / "Fuck no." / "I can't feel my toes anymore." / "Stop bitching."

welcome, PC players. here lies our intrest for the Yph series from Blitz players, 6 months ago.... now, itd your turn!

As a Swede I would love to hear your opinion on the Strv 103.
