Quieter, smoother, more fuel efficient – it sounds like the CAFE Foundation’s goals for its Sky Taxis.  ACHEON, a Euro-consortium of high-powered academic institutions, is working to bring together the Coanda effect with modern plasma technology to create a much-improved aerial travel experience. Having explored a few of the many aircraft that have attempted to use the Coanda effect, we now examine the work of the consortium of six organizations: four Universities, one Research and Tech Transfer Organization and one Research intensive SME (Small and Medium Enterprise – Nimbus S.r.l) from four European Countries (Italy, Portugal, the United Kingdom, and Belgium). The team, committed to exploring and demonstrating the benefits of ACHEON technology, is at work on possible applications for different …

A Not Totally New Idea After All

Delos Aerospace patented an electric landing gear system as early as 2007, according to their web site.  Steven Sullivan, an alert blog reader, provided the following lead for your editor. Delos says, “This revolutionary technology is a total systems integration of a fully electric landing gear and maneuvering system wherein axial flux disk motor/generators replace the old friction disk technology providing increased braking and maneuvering capability to the aircraft wherein there are many engineering benefits to eliminating the heat generated within friction based braking systems.” Use of these brakes could reduce takeoff distances and increase range by reducing fuel weight otherwise required for takeoff and cruise.  Power would come from an auxiliary power unit (APU), currently part of most large …
