The traditional farm Western windmill can handle high winds well.
False, there’s a limit, read about Betz’s law.

It's hard for me to imagine the design parameters for something that could survive and operate there.

How about a building-sized enclosure with intake shutters to direct/limit-as-needed the flow to internal dynamos? Here's some technical drawings as example (warning, google alert): Very, Technical

My comments were addressing the survival bit, not the power generation at a high speed. Proper construction of a windmill on a derrick type tower as seen in "Old West" movies" is quite stout.
The other 2 designs I mention were designed to be hardy. The capstan style (which I can find a picture of at the moment) is very stout. And if the winds will be too strong, a shield can be rotated around from the leeward side to the windward side, to block the incoming air.

I am sorry to break this to you but that is a failure of your imagination.

Some people are trying to work out how to run a useful rover on the surface of Venus (https://www.space.com/steampunk-venu...-nasa-jpl.html) without much in the way semiconductor electronics. Clockwork plays a big role. I proposed the use of thermal phase-change materials for an optical component in thenavigation and obstacle avoidance sub-system.
