Missed that blimp yesterday, must have been flying around before I got home from work.

Radials are amazing, but I still love the sound of a merlin at full chat

very cool. Take a look at this baby, every house hold should own one of these. A very trusting spectator crowd though, I dont think I would stand that close to the side of a running propeller.

I love rotarys. That huge mass spinning. A reverse radial where the crank is static and the cylinders spin around it.

That Bristol is also sleeve valve, which is a complexity all of its own - great VE though.

Now go look for rotary, (but not Wankel) engine.

Also:
Wankel
Split single
Napier Culverin, Napier Deltic and Napier Sabre
Commer TS3

I love unusual engine configurations, Any engineer trying something new has my vote.

You missed out the engine of my youth, the opposed piston, or specifically in my case the Leyland L60. 2 cranks, 6 cylinders, 12 pistons, 2 stroke, multi fuel, a couple of blowers and as unreliable as hell. Pity I cannot find any animations.

Edit, damm I should have read your list, the Napier Culverin is similar.

Opposed piston may be making a comeback. There was also a prototype motorcycle motor that worked in a similar fashion to a dual expansion steam engine - 2 small primary pistons where the explosions happened and a central larger piston which could extract more energy from allowing the exhaust gasses from either cylinder to expand further.

Empty, from this very forum once wasted about 20 minutes trying to get me to understand a Napier Deltic engine while we were sat having a coffee in Soho. Finally settling on "I'll send you a picture". It was the first time I'd met a motor with multiple cranks, and facing pistons. Once you've got your head around that most others are just about possible!

I'd not seen Cam engines either:

Thankfully these are animated

Very similar in principal to the Ducati desmo valve mechanism.
