Terrafugia in Transition

Terrafugia, a company started by a group of inspired college friends, has made it a mission to bring a flying car to the marketplace.  Quite literally – it’s in their mission statement: “Terrafugia’s mission is to create the ultimate mobility solution – flying cars.”  Even though the term is somewhat decried in current parlance – things like urban air taxis or sky taxis that would provide Urban Air Mobility being preferred. The Transition Their first craft, the Transition, earned a high hype score, with even Hammacher-Schlemmer including the flying car in their catalog.  It flew at AirVenture in 2013, demonstrating its folding wings and reasonable Light Sport Aircraft performance (even with a waiver for its “heavy LSA” gross weight). In some respects, the Transition is like Molt Taylor’s famous Aerocar, the first such vehicle certified for land and air travel.  It’s a great deal simpler to operate, though, not requiring a trailer like the Aerocar to haul the wings and …

Faster, Cleaner AND Less Pricey?

University of Michigan Research Sprinkled with Optimism (or Not) Can electric Vertical Takeoff and Landing (eVTOL) machines provide the swift crossing of  urban distances at a price that will attract the non-flying public? Can they do so while keeping pollution in check? A University of Michigan study, funded in part by Ford Motors, concluded that taking a short (depending on definition) trip in an autonomous electric vertical takeoff and landing machine might not only be quicker than a ground-bound journey through gridlock, but might even be less expensive.  These two factors are important if we are clean  the toxic atmosphere that hangs over our major cities, at least partly brought about by the constant transit of personal automobiles, public buses, and large trucks.  Another aspect of the study, though, showed that certain trips will be less polluting if taken by conventional automobiles.  This dichotomy comes from the nature of eVTOL flight compared to the distances to be traveled. Researchers published …

Carplane Makes a Comeback

Dean Sigler GFC, Sustainable Aviation 1 Comment

The German firm Carplane made an entry into the media a few years ago, especially when it compared its bi-modal flying car with a Burt Rutan design.  That started a brief kerfuffle of edgy comparisons between the two groups, but no necessary winner.  Now, having shown at least a finished and apparently drivable vehicle at Aero 2015, Carplane has renewed prominence in the media.  And the blog brings it all back, prepared for less-than-flattering comments. Stating what may stir others to contend for their rival mounts, Carplane makes a bold claim.  (The italicized and bolded word is Carplane’s emphasis.) “Flying cars will soon be a reality. And Carplane® is the world’s only flying car currently undergoing formal certification. Watch this page as we complete the process.” Some of the “automated” features on the design as originally conceived included a wing that pivoted out from its storage between the twin fuselages and attached itself to the central assembly.  The builders have apparently retained that …
