Joby Aviation is testing an autonomous Cessna Caravan with the United States Air Force, part of “a successful demonstration and validation of its SuperpilotTM autonomous flight technology.”   The 208 Caravan logged more than 7,000 miles and 40 flight hours over the Pacific Ocean and Hawaii.  A similar Cessna 208 Caravan has been flying similar missions for Reliable Robotics.  And yet a third Caraban is flying for Merlin Labs on the U. S. East Coast and in New Zealand.  The three companies have chosen to test their autonomous systems on Caravans because of the craft’s reliability and availability worldwide. Over 3,000 Caravans worldwide and their Pratt & Whitney PT-6 turboprop engines contribute to their ongoing popularity. Joby and Its Superpilot According to a company press release, Joby’s autonomous control system, Superpilot, was integrated into a Cessna Caravan 208, and tasked with a variety of missions, including: Mission Readiness: Superpilot demonstrated the capability to execute rapid cargo deliveries, hub-and-spoke logistics, inter-island transport, dynamic retasking, …

ZeroAvia recently presented at the Paris Air Show and is working intensively on certifying its motors and systems in the United Kingdom.   Their two motors are now joined by several components, including a liquid hydrogen fuel management system.  This system comprises a “lightweight metallic tank design and associated systems for filling, storing, and distributing the fuel as hydrogen-electric technology is increasingly applied to larger aircraft,” according to the company. Here, Val Miftkhov explains the workings of the company at this year’s Paris Air Show.  Of special interest, he compares the positives and negatives of sustainable aviation fuel (SAF) with those of hydrogen fuel cells, a matter of competitive importance. The Motors ZeroAvia has a pair of motors in the 600 kilowatt (804 horsepower) and 2,000 kilowatt (2,680 hp.) range, the ZA600 nearing certification in the UK and the ZA2000 attracting buyers in the regional airliner world.  The company claims several advantages for its motors.  They include, “90% Lower life cycle …

Universal Hydrogen flew the largest hydrogen-powered aircraft yet at Grant County Airport in Moses Lake, Washington.  The DeHavilland Dash 8 was powered on its right side by a MagniX motor and fueled by H2 from a pair of containers in the rear of the fuselage.  It made a 15 minute flight to 3,500 feet and settled back to a safe landing It carried “the largest hydrogen fuel cell ever to power an aircraft, “and Universal Hydrogen co-founder and CEO Paul Eremenko “declared the moment the dawn of a new golden age of aviation.” Prep for flight Lightning McClean, Universal’s modified Dash 8, normally flies with up to 50 passengers.  The penalty for using H2 for fuel is giving up 10 of those revenue-producing seats, Universal’s Plug Power containers taking up the back rows of the cabin.  Other gear included a rigorous evaluation of every component and system, the Dash 8 was ready for taxiing and test flights. Two large hydrogen …

An Historic Hydrogen Outing While Airbus and MagniX promote the near- and not-so-near virtues of hydrogen-powered flight, ZeroAvia has demonstrated such flight with the largest H2-powered aircraft so far.  Their Cranfield, England-based Piper Malibu flew on H2 power for the first time September 24 on an eight-minute circuit.  The blue Malibu reached 1,000 feet and a top speed of 100 knots true air speed. Quick to capitalize on the successful mission, , ZeroAvia founder and CEO Val Miftakhov held a press conference the next day.  In it, he explained his team,“has had discussions with seven aircraft manufacturers about possible retrofit and new-build applications for the propulsion system. He said the company has signed letters of intent with 10 airlines that have expressed an interest in the program based on presentations made to around 30 different prospective operators.” Earlier flights in Hollister, California and Cranfield were battery powered “to evaluate different elements of the powertrain.”   Unspecified modifications helped prepare the craft …

Harbour Air and MagniX Partner for First All-Electric Airline

A seaplane fleet is preparing to convert its fleet to all-electric operation, which will make it the first commercial electric airline. Harbour Air, a seaplane operator based in Vancouver, B. C. is partnering with MagniX, an Australian electric motor manufacturer with offices in Seattle, Washington.  You may see Harbour’s DeHavilland Beavers, Otters and Twin Otters lifting off from or landing on  Lake Union when you drive by on the I-5. Harbour Air flies “more than 30 seaplanes” on 12 routes that carry more than a half-million passengers on 30,000 commercial flights a year.  The smallest craft they fly, the DHC-2 Beaver, carries six and burns about 20 gallons per hour of 100 low lead fuel – which now costs from just under $5.00 to over $7.00 in the Seattle region.  Obviously, fuel costs and maintenance on an engine (on the Beaver) that has not been built since 1953 must be of concern to operators. MagniX is Zero Emissions MagniX CEO …
