Emil from The Practical Engineer purchased two electric duct fans for this project. A duct fan has a propeller-like rotor fan installed inside a cylindrical duct, and generates thrust by rotating it.

Multi-rotor fixed-pitch aircraft – quad, hexa, octa copters – are the current flavor of the season with hobby and amateur flight enthusiasts. The serious aero-modeling folks prefer their ...

Although personal drones are becoming increasingly popular, a lot of people are still understandably intimidated by their exposed propellers. Not only can those whirling blades hurt people, but they ...

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 ...

Want to learn why ducted propellers improve both thrust and efficiency? Well, we’ve got both the lesson and the teacher for you. [Bruce Simpson] isn’t exactly a household name, but we bet most of you ...

Lilium was founded in 2015 and spent over $1.5B developing advanced technologies related to electric vertical takeoff and landing (eVTOL) aircraft The Lilium patent portfolio is made up of key ...

Urban Aeronautics has manufactured new propeller blades that will be fitted to its unmanned AirMule ducted fan vertical take-off and landing aircraft. Using in-house capabilities, the company has ...

Most of the work so far on the electrification of aviation has involved propeller-driven aircraft and the development of electric propulsion units that can replace turboprop engines. Now GKN Aerospace ...

Key point: Many countries have tried to use duct-fans in their military planes, but they aren’t common for a good reason. Here’s why China’s “UFO” isn’t much of a breakthrough. A Chinese firm claimed ...
