Cycloidal rotors employ blade elements that translate and rotate along a trochoidal path, enabling continuous adjustment of blade pitch and orientation to vector thrust in real time. This mechanism ...

When it comes to VTOLs (vertical take-off and landing), such as helicopters and other aircraft, the most common approach used to lift these vehicles is to use rotors that rotate on a vertical axis. In ...

Austrian startup CycloTech has begun tethered flight tests of a demonstrator equipped with its cycloidal rotor technology for vertical-takeoff-and-landing aircraft. Flown indoors initially, the ...

The aircraft lifted only briefly off the ground, hovering under remote control. Still, the moment mattered. On March 27, 2025, an experimental vehicle called BlackBird rose into the air during its ...

Gearboxes let engineers adjust servomotors’ operating speed and resulting torque. But understanding the two major types will lead to lower costs and better performance. Engineers have long used ...
