With my time consumed by more than one project, I don't get the time to blog as often as I like.But I wanted to share a 3D "doodle" I mad in Fusion 360.
It's a rudimentary hydraulic reservoir, based on the type that has been used for many aircraft for quite some time. I modeled it because I find a certain inspiration in a simple solution to a problem.
The challenge for this hydraulic system? How is a supply of hydraulic fluid kept for the emergency system, should the primary system fail, and bleed out completely?
The solution? There are two intakes in the reservoir. The inlet for the primary system uses a standpipe, which sits higher in the reservoir than the inlet for the emergency system.

That leaves enough fluid for the emergency system, allowing the pilot to do things like lower the landing gear and flaps for example.

It's a clever way to solve a problem!
Naturally, there is much more to an aircraft hydraulic system than just this reservoir. There are pressurized reservoirs, hydraulic fuses which close if hydraulic fluid starts flowing above a certain rate, and redundant hydraulic systems found in airliners.
If you're inclined, you can read up on aircraft hydraulic systems with the FAA handbooks found at this link. The PDFs are free, so there's no reason not to take a look!
