David Ullman, a professor emeritus at Oregon State University, predicted electric flight’s future in articles in 2009* and 2010**.  His predictions have come (mostly) true and David is working to fulfill the rest.  His background in mechanical and aeronautical engineering provides credibility for his prognostications, and he’s taking practical steps to take electric aviation to a next, very creative level. While Uber’s Elevate Summit in Dallas earlier this year focused on big-money players in the vertical aviation world, David and co-creator Vincent H. Homer promoted their paper, “The IDEAL for Near-VTOL Aircraft.”  IDEAL represents “Integrated Distributed Electric – Augmented Lift” flight, using “thrust from distributed electric propulsion to improve the lift and drag performance of the aircraft during takeoff, cruise …

Lugosi Enterprises Pioneers Late-Night Drone Deliveries

Even while Jeff Bezos at Amazon and competitors like UPS and FedEx strive to deliver packages to your front door, a Transylvanian experiment in extreme biomicry promises to make delivery in the dark of night the new standard. While other drone makers use fixed- or rotary-wing configurations, Lugosi Enterprises relies on a radical, human-powered ornithopter with the ability to change shape and size depending on the stage of the mission in which it is engaged.  This proprietary technology is shrouded in secrecy, but enables the wingsuit wearer to shrink to an extraordinarily small size, at which point, according to Lugosi spokesperson Dwight Frye, the operator can fly an undisclosed distance in total silence, except for an occasional annoying high-pitched piping noise. …
