One of the most fascinating aircraft in the eVTOL space has moved into flight testing with a new large-scale prototype.

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

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 ...

As boring as propeller designs may seem to the average person, occasionally there’s a bit of a dust-up in the media about a ‘new’ design that promises at least a few percent improvement in ...
