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 ...

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

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

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 ...

While propellor-driven aircraft are generally slower ... shockwaves generated or push through transonic drag with enough thrust to maintain lift, the noise level alone seems prohibitive." ...
