Also known as Voith-Schneider propellers, cyclorotors are barrel-shaped propulsion systems that spin at a constant speed, but can vector thrust nearly instantly in 360 degrees by adjusting the pitch of blades running the length of the barrels. They're currently being considered for a variety of electric aircraft and UAV applications.

  • Most drones need to tilt to move and correct against gusts of wind. Pitch Aero's Astria, however, can keep itself preternaturally level and stable, thanks to a novel use of cyclorotors that opens up a range of use cases other drones can't handle.
