The Bombardier Global 7500, is certified for a Maximum Take-Off Weight (MTOW) of 114,850 lb (52,000 kg). At maximum power, ...

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

That’s not really what you want if you’re testing brushless motors and prop configurations, anyway; similarly sized props can have very different thrust profiles. Instead of building a dyno ...

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 ...

Swiss marine giant ABB has spent more than a decade developing a radically different Voith-Schneider take on a marine ...

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 ...
