The high-efficiency aerodynamic and aeroacoustic optimization framework comprises the following key modules: 1) Shape parameterization, which transforms the baseline geometry into a set of design ...

Electrification is seen as having an important role to play in the fossil-free aviation of tomorrow. But electric aviation is battling a trade-off dilemma: the more energy-efficient an electric ...

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 performance ...

Collins Aerospace says the eight-blade NP2000 composite propellers on the Lockheed Martin C-130H enable more traction for a given propeller diameter. Credit: Collins Aerospace Propeller manufacturers ...

Could the secret to transforming propeller design lie in the dimples of a golf ball? It might sound far-fetched, but the same aerodynamic principles that allow a golf ball to soar farther and faster ...

As part of Digital Propulsion (DigiProp), the National Composites Centre (NCC) has designed and manufactured a full-scale prototype of a propeller blade and its manufacturing system for turboprop ...
