Flying high and down under, Amprius, the San Francisco Bay area-based battery developer and maker, announced 450-Watt-hour per kilogram cells, and seemingly immediately secured orders from three major clients.  One client of the three is a British specialist in HAPS (High Altitude Pseudo Satellite) aircraft.  A probably unrelated sale went to an Australian light plane maker unveiling the country’s “first commercially produced electric aircraft,” a two-seat trainer. BAE/Prismatic BAE Systems has collaborated with Prismatic, a HAPS pioneer, in the development of solar-powered unmanned aerial vehicles (UAVs).  The partners have crafted two prototypes of the PHASA-35 unpiloted aerial vehicle, a 35 meter (114.8 feet) span airplane weighing 150 kilograms (330 pounds) capable of carrying a 15 kilogram (33 pound) payload. Solar cells power the craft’s electric motors during the day and charge the Amprius batteries that keep it in the air at night. Amprius claims, “The new 450 Wh/kg cells are the only known commercially available batteries of their kind that …

Aussies Complete Electric Aircraft World Endurance Record

A three-pilot crew accompanied by a five-person, multi-vehicle support crew have set a world endurance record for electric flight.  The team traversed 1,350 kilometers (839 miles) over not-always-hospitable terrain and through not-always-welcoming weather.  Participants in the record attempt held up admirably, with few problems other than seemingly constant cross-wind landings and often uncooperative weather. Their flight made it onto Australia’s largest television network. The Airplane Eyre to There Managing Director Barrie Rogers explains the limitation of the aircraft and the effect this had on the flight.  “The Pipistrel Alpha Electro – dubbed the ‘Tesla of flying’ – currently has a flight time range of about 1 hour and cruising speed of 85 knots (157km/h) so we’ve had to very carefully plan each stop and build in contingencies for weather such as strong head winds.” The craft itself shows the characteristics that make it a good trainer – but probably not one’s choice for a world endurance record.  The 10.5-meter (34.5 …

Aussies Attempt Electric Aircraft World Endurance Record

An Australian flying school and a flight planning software enterprise are in the middle of a series of flights that attempt to break an electric aircraft world endurance record. The cleverly-named Eyre to There Aviation announces that, “In partnership with platinum sponsor AvPlan EFB will aim to break a world endurance record for an electric aircraft with a 7-day, 18-stop flight around South Australia.” According to the organizers, “The proposed route will include flying across to the Lower Eyre Peninsula and inland back to Port Augusta for flight sectors around the Yorke Peninsula before arriving back in Adelaide, subject to aircraft performance and weather.” A 1,150 kilometer (714.6 mile) trek, the flight would “shatter the previous record of 750 km (466 miles) flown in September 2020 in [Switzerland and] Germany.”  The Europeans needed 11 stops for recharging on their trip, so the 18 planned by the Australians is comparable for the planned distance.
