Ducted fans have emerged as a promising propulsion solution for modern Unmanned Aerial Vehicles (UAVs), particularly in applications that demand high safety, efficiency and low noise levels. Enclosing ...

This hybrid engine innovation blends fuel generation with electric propulsion, enabling drones to fly longer distances while reducing noise for stealth missions.

Whisper Aero, a Tennessee start-up, spent the last two years developing a propulsion system that it says is quieter and more efficient than any other. Now it has finally revealed part of its secret: ...

When Daniel Schubeler began working on electric ducted fans in 1997, the technology was in a nascent stage. Batteries at the time were far too heavy and more-efficient brushless motors were not yet ...

Electric aviation is in its infancy, equivalent to the piston era of a century ago. But propulsion startup Whisper Aero is already working to enable the transition from the propeller age to the jet ...

Whisper Aero says its electric aircraft propulsion systems are "20% more efficient and 100x quieter than anything else on the market." They're designed for drones, planes and possibly eVTOLs, and ...

A Chinese-developed hybrid propulsion approach is combining fuel-based generation with an electric drive to ...

Urban conditions are uniquely tricky to navigate for electric vertical take-off and landing aircraft.

When it comes to the emerging UAM (urban air mobility) sector, some companies focus on developing specific eVTOLs (electric vertical take-off and landing), and others on developing vertiports. But a ...
