NASA’s Glenn Research Center reviews the prevalence of fossil fuels in keeping us flying for over a century. “Since the beginning, commercial planes have been powered by carbon-based fuels such as gasoline or kerosene. While these provide the energy to lift large commercial jets into the world’s airspace, electric power is now seen as a new frontier for providing thrust and power for flight.” Noting the use of hybrid and turboelectric power used to increase efficiency in cars, boats and trains, NASA has set a goal “to help the aircraft industry shift from relying solely on gas turbines to using hybrid electric and turboelectric propulsion in order to reduce energy consumption, emissions and noise.” This would require a large shift …

Getting a GloW On

Great Britain has recently allowed very light aircraft to fly under SSDR (Single-Seat DeRegulated) rules, which permit single-seat aircraft with an MTOM (maximum take-off mass) of not more than 300 kilograms (660 pounds) and a landing speed of not more than 35 knots (40.27 mph or 64.82 kilometers per hour).  With weights and speeds a bit higher than those allowed for American ultralights, these would be desirable as a way to expand the number of aircraft flying under ultralight rules.  How a machine such as the ProAirsport’s GloW will be regulated in America remains to be seen. Formed in 2014, ProAirsport will built light aircraft around the new British rules while adopting ASTM F2564, Standard Specification for Design and Performance …
