Chris Rosser has pulled off something rather extraordinary with the AOS Supernova 3220. After some clever tinkering—including selecting a 32mm stator from RCM Power and employing a touch of Bayesian optimisation—he and the team managed to clock an eye-watering speed of 580 km/h with the ‘Peregrine’ drone during a rather warm jaunt in Dubai. Apparently, dry ice was the secret ingredient to keep those motors chill while breaking records. Not your average bedroom project, is it?
Now, before you rush off to replicate this feat in your garage (please don’t), let’s unpack the engineering marvels involved. The team not only had to overcome previous speed limitations but also grappled with aerodynamics that demanded a svelte motor design to minimise drag. Chris’s genius lies in the magnetic geometry, which remains optimal across various configurations—essentially allowing for a bit of flexibility in matching props and cells without redesigning the wheel… or in this case, the rotor.
Of course, it’s not all fun and games; they’re eyeing a new target of 624 km/h, which will undoubtedly come with its own set of headaches. Expect future versions of the Supernova to be reinforced and possibly made from even more exotic materials. Because why not push the boundaries a little further, eh?
