Thus [Valkyrie Workshop] has come up with a simple but ingenious rig to evaluate a motor and propeller combo without ... allowing a direct readout of the thrust in grams or kilograms.

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 ...

The action of a propeller is that of a rotating wing where the lift provided by the wing is the desired thrust for propulsion. The blades also have an associated drag which reduces the overall ...

Airplanes obviously employ very different engine technology compared to ground vehicles, but some actually do use a form of ...

“What you need is relative motion.” In addition, the shape of the channel deflects propeller thrust downward, as much as 26 degrees. With this extra lift, an aircraft with a channel wing is ...

Fly without wings or propellers? One team just made it happen—this breakthrough could forever change how we take to the skies.

and is described as essentially a cycloidal propeller – where vertical blades are mounted to a spinning circular plate to provide thrust. It's not a new idea, the Cyclogyro from and few years ...

The system continuously monitors wind propulsion performance, ensuring reliability and optimising sail technology and control ...
