Rotron single rotor UAV engine
 

Anybody heard of this?

Rotron RT600 HFE Heavy Fuel Rotary Engine for UAV, Drone & VTOL Applications

They show the rotors in the PDF brochure; it looks similar to Woelfe Engineering's kart engine where the fuel-oil mixture also lubricates the internals before entering the combustion chamber.

In the RX-8 development book they show Mazda tried even 3 spark plugs on leading and trailing, but they said it didn't make that much of a difference in efficiency. Perhaps with a smaller displacement it works better?

Rotron also provided the engine for Crighton Racing's experimental racer motorcycle.

holy shit that looks awesome. so many ideas entered my head on what id do with it lolol. too bad im broke lololol

never heard of it until now, but it does look interesting. i am very tempted to create some reason to "NEED" one. :)

The extra sparkplugs could be there for cooling purposes. But damn son 4?!?

That's a twin-rotor, gents, not a single. And it's made to run on essentially thickened kerosene, so ignition and flame-spread would be an issue at higher RPMs. So, more plugs.

I originally copied the link for the single rotor engine, but changed the link and not the title.

Thanks for clearing up the fuel info., they show two versions of each single and twin rotor engine running on avgas and jet fuel which I didn't look up until later.
