Having circumnavigated the world by balloon and solar-powered aircraft, Bertrand Piccard is ready to make a third around-the-world flight – this time in Solar Airship One, powered by the sun and hydrogen fuel cells.  Able to make the 40,000 kilometer (24,855 mile) trip in one gigantic hop, the 151 meters (495.4 feet) long craft will be borne aloft on 50,000 cubic meters (1,766,000 cubic feet) of helium. Unlike his lonely stints at the controls of Solar Impulse 2, Piccard will be joined by two worthy co-pilots; Dorine Bourneton, “The first disabled woman to become an aerobatic pilot (Bourneton was severely injured at age 16 in an aircraft accident) and Michel Tognini, a former French Air Force fighter pilot and European Space Agency astronaut (Tognini has been twice to space, in 1992 and 1999).”  The Craft Its helium sealed in 15 large gas bags that emulate the shape of the airship, the ship carries 50,000 cubic meters (1.77 million cubic feet) …

eCSTOL: Longer Range Commutes on Less Power

Competition is growing in the electric Vertical Take Off and Landing market, with 407 potential builders listed in eVTOL News.  Vertical flight takes power, though, and with available batteries limiting range, most such vehicles can make only short hops.  Alternatives that allow speedier, longer flights, in the form of electric Conventional Short Take Off and Landing (eCSTOL) aircraft are in development. Such craft offer the benefit of requiring less power for takeoffs and climbs, being more aeronautically-based than power-based.  Airflow, for instance, claims operating costs for their eCTSOL craft is one-third that of an eVTOL or helicopter. We will look at three eCSTOL craft that seem to making headway at this time.  The infrastructure (in two cases below) to support their flight may already exist. Airflow Curt Epstein, writing in Future Flight, under the headline, “Infrastructure Needs for eSTOL and eVTOL Aircraft May be Closer than Imagined,” notes the “intense study” being undertaken.  Speaking at the Vertical Flight Society’s  Electric …
