We Design Underactuated VTOL Propulsion Systems...

Electron Flight is an R&D company developing innovative, simplified propulsion systems for electric Vertical Take-Off and Landing (eVTOL) aircraft. Our company maintains a lean profile with a focus on practical innovation for electric aircraft propulsion. The company emphasizes mechanical simplicity, robustness, and reduced complexity compared to traditional eVTOL designs, which often rely on actuators, linkages, swashplates, or complex tilt mechanisms. Our goal is to enable more reliable and accessible electric vertical takeoff propulsion for the growing eVTOL and advanced drone space, prioritizing elegance through simplicity.

SCOPIC (Shaft Controlled Pitch Change) Technology

SCOPIC technology is the final solution for every application involving a spinning propeller blade or rotary wing. SCOPIC technology will replace every current propulsion system by providing collective and/or cyclic pitch control to any system without using actuators, swashplates or other complex mechanisms...

TORC (Torque Operated Rotor Control) Technology

TORC technology provides tiltable rotors and variable pitch blades without requiring actuators, linkages or other complex mechanisms.

Rotor orientation and blade pitch are controlled by rotor torque. Motor direction is reversed to go from vertical to horizontal flight modes. Simpler configurations use a bidirectional propeller.

PTERO (Passive Tilt Electric Rotor) Technology

Airframe and rotors are passively positioned by differential thrust, gravity and relative wind. No servos, tilt mechanisms or control surfaces required. PTERO (Passive Tilt Electric Rotor) technology is a mechanically simple and innovative approach to tiltrotor propulsion systems. By enabling passive rotor tilting without traditional linkages or actuators, the system achieves precise control during transition from hover to forward flight through differential thrust, where variations in motor thrust naturally manage rotor orientation. This design minimizes weight, reduces failure points, and enhances reliability.
