Items like this deserve to be showcased in full detail with explanations to it's opperation.

I got more questions than answers after that demonstration 😮

So back in the 90's I had a very old college professor who worked in white sands Arizona during the cold war, helping design the first electronic guidance systems for minute man missiles. He told us lots of stories, then half way thru he would just stop the story and move on. One of his stories he said there was a neat "clockwork" gathering dust on a shelf. It has gyroscope and a bunch of gears and the whole thing was about the size of a basketball. So he cleaned it up and put it on his desk. Some time later, a big brass general was walking by and stopped and said "where did you get that", and he told him it was on a shelf somewhere, and the general informed him that it was a Russian ballistic missile guidance system, and that possibly it wasn't really a great idea to be a paperweight on the desk of some mathematician. And then he laughed and never finished the story.

Гироскоп и механическая система стабилизации курса . Прибору минимум 50 лет, но в принципе в его работоспособности сомневатся не приходится . Просто сейчас применяются другие системы основанные на других принципах работы .

And to think that every part was machined by hand. No CNC back then. Amazing!

My father, in 1942, was on the cruiser HMS Trinidad in the arctic. They fired a torpedo but the bearing mechanism, shown in the video, froze because of the extreme cold. As a result the torpedo went in a circle and hit the ship.

and to think, that was all made on an engine lathe and Bridgeport.

I once had a tiny 1 1/2” diameter gyro from a guided missile that was supposed to be spun up by an explosive charge inside a little pressure tank. I thought it would be cool to spin it up with compressed air like you just did. It was cool. . . Until it disintegrated. I had 47 stitches in my left hand to re attach a finger and a huge bruise in the middle of my chest from a tiny piece of titanium shrapnel about the size of a dime. When it came apart the impact knocked me backwards about 6 ft. You might ought to monitor the RPM of that thing if you know it can withstand 20, 000 revs.

Whether it’s a mechanical systems/analog computers in ww2 or rudimentary electronics and circuit boards during the Cold War, it’s clear that the military spares no expense and uses the latest state of the art systems for its weapons. It really makes one wonder what’s put into missiles designed now.

[godlugner]

The grease in those bearings is impressive

[thefinalkayakboss]

The fact that they figured out a way to do this without solid state electronics- and it even worked occasionally, is incredible.

эта штука держит торпеду по курсу, не давая ей отклоняться... механизм без электроники, сейчас это выглядит дико...

[zacharytracy]

I love everybody admiring this creation for being masterfully crafted when in reality the MK.14 torpedo was one the worst-designed and produced torpedoes in all of human history. They didn’t test fire A SINGLE torpedo before mass-production and war started.

They went twice as deep as they were set to, the magnetic detonator rarely worked, the impact pistol detonator broke off when it hit a ship before the mechanism could detonate the torpedo, they didn’t swim straight AND, possibly quite frequently, ran in a circle and hit their own ship.

Multiple submarines were suspected to be lost as a result of this phenomenon and at least 1 incident was confirmed by survivors.

Worst part about it: The Bureau of Naval Ordinance blamed the submariners for improperly maintaining the torpedoes (while not even distributing service manuals because they were considered “secret” even though it was a well-understood technology at the time worldwide). They REFUSED to address ANY of the problems and denied that ANYTHING was wrong with the torpedoes. Drachinifel has a good video on it.

And it just gets blown to smithereens. We humans are indeed nuts.

"What an intricate piece of equipment I wonder how he's goin-"
*pulls out blow gun*

...А где ты работаешь?
-Делаю гироскопы.
-Ой, не верю я этим гироскопам....

[DarkMatterX]

Extraordinary craftsmanship. Each and every one of those pieces was machined by a person. Yes, yes, yes, cnc is more precise. It's exactly because people aren't flawless machines that such handcrafted precision is so amazing.

[mitchf.]

Such a complex and expensive looking system for something that would just be blown up or lost in the bottom of the ocean

[blakeengland]

it's a submarine device that's used to stop the boat from shaking side to side when rocking but much more sophistaced gyroscope

note how the spherical "bearing" shifts directly back into north/south position even @ 20k rpm

[НатальяСотская]

Прибор направления по курсу. Есть в любой торпеде или ракете. Только в ракете их, как правило, не менее двух-трех.
