UAV Engines Limited (UEL) is a company dedicated to the design, development and production of Wankel-type engines for the propulsion of small and medium sized Unmanned Air Vehicles (UAVs).

The technology is based upon the rotary engine Research and Development work carried out by Norton Motors Ltd during the years 1969 to 1992.



The AR682R aero-engine has been developed to power UAVs which require up to 120 bhp. It is based on the proven AR642 core engine which was designed to meet UK CAA / European JAR-E and US FAA FAR-33 certifications for manned flight.

Back in my previous life as a rocket scientist, we ran a bunch of electromagnetic tests on a military UAV powered by a Norton rotary engine. That was in the early '90s, I think. I've forgotten who the manufacturer was. We also tested a UAV powered by a Moto-Guzzi v-twin engine.

That does it. Anti-clockwise rotation is out of the question for me. Next thing you know, we'll be drinking beer upside down.

Time Might Go Backwards , if its Anti Clockwise .
Or youd have to fit it with the Gearshift on the Left , and the engine upside down .

Hey Hobot, did you check out the Vincent triple rotor mill in Nov`12 Cycle World? Back in the day Vincent did sell their engines for target drone use.

Cool... that must have been with General Atomics. I know an engineer that worked on that project. He's well known in Guzzi circles for his work on fuel injection.
