Perlan,  Egrett,  and Airbus at Oshkosh

Most Interesting Formation Flight at Oshkosh? Perlan 2, its Grob Egrett tow plane, and sponsor Airbus gave AirVenture 2022 attendees a glimpse of future records and promising technology.  Few people outside the Perlan Project have witnessed these two-planes flying in close formation, linked by a tow rope. Initial attempts to get Perlan to an altitude where it could catch high-level mountain waves were hampered by the relatively slow climb of the conventional high-wing craft. Because Einar Enevoldson, founder of the Project, had been a test pilot for the Grob aircraft works in Germany, he had reached a record altitude of 60,867 feet in their Stratos 2C, a twin-engine research craft powered by triple-supercharged Teledyne engines.  The Stratos is the highest flying piston-engine airplane. Its single-engine cousin, the Egrett flies behind a turboprop engine, though, which enables towing the Perlan to the stratosphere for its final search for record altitude. Spectators at AirVenture got a small taste of that stratospheric adventure, …

Volocopter Starts Autonomous Air Service Trials in Dubai

In June, Dubai’s Road and Transit Authority (RTA) announced its plans to test fly Volocopter’s 200 over the country by the last quarter of this year.  The government and Volocopter have succeeded in meeting that timeline, with demonstrations this week of Volocopter’s quiet ability to fly autonomously (although without passengers so far).  Aerial transit will be a small part of a much broader scheme, the government intent on providing excellent public transportation, as shown in this well-produced video. To ensure meeting Dubai’s ambitious goal, Volocopter’s designers tested the machine thoroughly in German skies.  Note the Grob Strato 2C by one of the hangars, the twin-engined airplane in which Einar Enevoldson, founder of the Perlan Project, set the still extant world altitude record for propeller-driven airplanes in 1995 – 60.897 feet. With fresh infusions of 25 million euros from Daimler AG and “serial entrepreneur” Lukasz Gadowski, Volocopter has been able to achieve this early trial as a sky taxi.  Both Volocopter …

EAS IX: Calin Gologan Talks SolarStratos 

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Calin Gologan, founder and CEO of PC-Aero GmbH, has many electric and solar-assisted aircraft flying right now, and is responsible for the design the Aero Electric Aircraft Company’s SunFlyer training airplane, 20 of which have been ordered by Spartan Aeronautical University.  The initial Elektro One has flourished in a number of variants, including the SunFlyer, a two-seat, side-by side trainer developed with George Bye in Colorado. Another variant of that original design, Solar Stratos is destined to combine record-setting altitudes with scientific research.  Its banner, “Manned Flight at the Edge of Space,” highlights the craft’s intended mission to reach 80,000 feet as its initial goal, a record that will be hard to beat.  Its mission is also a research venture, with Calin serving as Chief Technology Officer of SolarStratos. The initiator of SolarStratos, Raphaël Domjan, is now paddling his way through an Arctic Passage in one of two solar-powered kayaks, accompanied by Anne Quéméré, described as a Breton sailor.  Their …
