Wisk Wows at Oshkosh

A Wisk Cora flew autonomously several times along the length of the 8,002-foot main runway, a first at the Experimental Aircraft Association’s 2023 AirVenture in Oshkosh, Wisconsin.  The July 25 event was, “The first-ever public demonstration of a fully autonomous eVTOL fixed-wing airtaxi,” according to the company. Under development and appearing in different configurations over the last several years Wisk’s aircraft have flown in Hollister, California and in New Zealand.  Cora represents the fifth generation of such vehicles.  Wisk, a Boeing partner, is not stopping there. The flight from another perspective, with an explanation of the noise on the soundtrack: “The noise is the 787 APU, not the @WiskAero. ‘  Note how the noise drops as the auxiliary power unit shuts down, with crowd noise competing with the Cora for dominance. https://twitter.com/i/status/1684023361804943360    A Future with Four Seats The latest iteration for the firm is their sixth-generation craft, simply called Generation Six.  It’s a four-seater, with ample room for passengers and …

Faster, Cleaner AND Less Pricey?

University of Michigan Research Sprinkled with Optimism (or Not) Can electric Vertical Takeoff and Landing (eVTOL) machines provide the swift crossing of  urban distances at a price that will attract the non-flying public? Can they do so while keeping pollution in check? A University of Michigan study, funded in part by Ford Motors, concluded that taking a short (depending on definition) trip in an autonomous electric vertical takeoff and landing machine might not only be quicker than a ground-bound journey through gridlock, but might even be less expensive.  These two factors are important if we are clean  the toxic atmosphere that hangs over our major cities, at least partly brought about by the constant transit of personal automobiles, public buses, and large trucks.  Another aspect of the study, though, showed that certain trips will be less polluting if taken by conventional automobiles.  This dichotomy comes from the nature of eVTOL flight compared to the distances to be traveled. Researchers published …

MAGiCALL Motor/Controller Vies for Simplicity, Lightness

Dean Sigler Electric Powerplants, Sky Taxis, Sustainable Aviation 1 Comment

MAGiCALL, a California-based firm whose slogan, “Innovative Magnetics to Power Your Products,” covers everything from aircraft to medical applications, has introduced a combined MAGiDRIVE™ integrated motor and controller line of products.  These are of particular interest for electric aircraft designers, since the company has been picked to supply motors to the Airbus A3 Vahana project. Whatever else they may accomplish, the many multi-rotor sky taxis will create a demand for a great number of motors, controllers, and battery packs.  16 on every Volocopter, eight to 16 on every Ehang, and eight on every Vahana will promote mass production, perhaps leading to a Model T moment where such technology becomes universally affordable. What Ford did for automobiles, most of the current crop of sky taxi designers are attempting for the democratization of flight.  They could start with Ford employee Bill Stout’s motto, Simplicate and add more lightness.”  He, by the way, designed the Ford TriMotor, the first certified airliner in America, …

Whistling at High Frequencies in the Dark

The same millimeter wave-length scanning that sees through your clothes at TSA’s very personal pre-flight inspections in airports could also provide a new type of heads-up display for pilots.  With an ability to distinguish power lines and other finely-resolved images in otherwise total visual blackouts, the technology could find a place in navigation, searches, and even private flying.  A few drawbacks stand in the way, however. Extremely high frequency MMW devices sense objects at a range just below that of the lowest frequency infrared light.  The high frequency allows a high level of discrimination in imaging. Used in automobiles for applications such as radar braking and adaptive cruise control, the potential for adapting such devices to weather flying is promising.  Used today in military helicopters, it is highly useful in places like Afghanistan, where blackouts of Biblical proportions darken mountain passes at incredibly high density altitudes.  Operation Eagle Claw, the 1979 rescue attempt of 400 American prisoners in Iran was …
