Skydweller Aero, an adaptation of Solar Impulse technologies, is working with the U. S. Navy to provide ultra-persistent flight capabilities.  It’s using Solar Impulse Two, for which Skydweller purchased the assets and intellectual property rights.  Being flown in Spain at this time, the aircraft’s 2,900 square feet of solar cells provide two kilowatts of power, and may be augmented by hydrogen fuel cells in future. In Spain Skydweller founders John Parkes and Robert Miller have headquarters in Oklahoma City, Oklahoma, but are performing flight tests in Spain, coordinating efforts with the University of Castilla-La Mancha (UCLM). After successfully completing ground tests that checked the structure and control systems, Skydweller works toward crafting the software that will guide it on unpiloted missions, scheduled to last at least 30 to 60 days.  Such persistence, long sought by the military for ISR (Intelligence, Surveillance and Reconnaissance) missions, is also essential for many future civilian applications.  Co-founder John Parkes explained this to Aviation Today.  …

Two different machines, with vastly different purposes and unique looks, are flying electrically above Wittman Field for the worlds’ biggest airshow.  The Experimental Aircraft Association’s gathering, having skipped a year because of the pandemic, is back with nearly twice the number of attendees.  It’s a crowd ready to be rocked. Volocopter Helena Treeck, head of public relations for Volocopter GmbH, is on scene at AirVenture, not only promoting her company’s machines, but granting interviews and reporting herself. She shares the experience.  “The crewed Volocopter 2X took off at 2:45 PM CST for a 4-minute flight at ~164 feet and a top speed of 18 mph over Wittman Regional Airport as part of EAA’s AirVenture aviation celebration. Event attendees were able to watch the Volocopter 2X fly and take a seat in the VoloCity model at Volocopter’s booth to experience these aircraft. Nicknamed the ‘World’s Greatest Aviation Celebration,’ more than 600,000 visitors are expected to come to see pioneering designs in …

Borschberg, H55 Introduce BRM Energic

Leadership is about empowering people to make them owner of their world, and constantly challenging them to make them extend their known territory.” Andre’ Borschberg Andre’ Borschberg’s current challenge, shared with Bertrand Piccard, involves their Solar Impulse Foundation, whose goal is to foster 1,000 solutions “that protect the environment in a profitable way.”  “Profitable” helps produce results, and with Piccard being a psychiatrist, ensures the self-interest that drives many also drives a certain level of altruism in saving the environment. Borschberg and two other Solar Impulse leaders, Sébastien Demont and Gregory Blatt, founded H55 and produced a modification of the Silence Twister, a single-seat aircraft with a Siemens motor.  Their latest conversion, following their philosophy of, “Building up experience by flying existing airplanes with electric propulsion,” uses what looks like an Emrax motor in a Bristell Energic two-seat training craft. “Single Engine Dual Battery Pack System” Energic is an electric variant of a Czech Republic Light Sport Aircraft, with an …
