My heart sank to the floor when I saw the slip ring contacts. Thank you for documenting this beautiful piece of engineering for future historians and nerds like me.
Michel, would this be a floated design like the Apollo IRIG, where the liquid was used to float a hermetic rotor enclosure near zero buoyancy, to reduce friction loads in the bearings? They actually called the spherical enclosure that held the rotor the “float”. In Apollo the fluid was also used as a dampener for the float. I wonder if this is a similar idea.
4:20 For those that were curious. This is a solder-band seal. Very common means of hermetically sealing flight hardware that will see extremely dynamic environments. Thank you Michel!!!! This is going to be an awesome series!!! 😀

Awesome artifact and awesome tear-down! Now that you know the functions of the brushes you can get that second gyro running without having too much trouble. First gyro I've ever seen using liquid. Amazing precision and quality. The best money could buy at the time.
Yes, I tried to build such tool, a small aluminium plate which can be inserted between contacts then rotated to spread them but it was not obvious. It is a delicate task performed I assume by a qualified worker.

Il y a une amélioration certaine de l'accent ! on sent la pratique :) très belle review à nouveau !
What a beautiful design, absolutely wonderful to get a look inside. Many thanks.

They actually called the spherical enclosure that held the rotor the “float”. In Apollo the fluid was also used as a dampener for the float. I wonder if this is a similar idea.
I am not sure, I think that the temperature should be controlled to have neutral buoyancy. I think it is just a damping oil.
@@lelabodemichel5162 Yes, definitely the temp had to be tightly controlled on the Apollo IRIG. No heaters in yours?
Not on mine. I have done a quick reverse engineering and I didn't find any connections for heaters or temperature sensor.

Damn that competition for teardowns of impossible to find devices is becoming more and more difficult😅
I’ve always wondered where do people find these things?

You get all the cool toys! :)
Thank you for taking us on this journey of exploration.
nice
Functional engineering art.
Thank you for sharing

Huge respect Michel!
Wow, what a fabulous piece of kit. Very impressive. Would love to know more about the control system and data output.
It looks like the slip ring assembly can accommodate some type of tooling to retain the contacts during removal or install.
Yes, I tried to build such tool, a small aluminium plate which can be inserted between contacts then rotated to spread them but it was not obvious. It is a delicate task performed I assume by a qualified worker.
There were only a few hundred of these made, so they are somewhat rare. Nice find, especially at such a reasonable price!

vraiment impressionnant , un grand merci pour le partage c'est toujours un reel plaisir.
Tecnologia surpreendente
Looking forward to part 2...
