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 …

Electric, Small, and Challenging

Dr. Ilan Kroo, a professor of aeronautics and astronautics at Stanford and designer of the Swift ultralight hang glider, among others, has a different kind of mission – that of reshaping small aircraft for the greatest efficiency. Lessons learned from light aircraft can be applied on a larger scale – but keeping it simple and light to begin with allows less expensive learning, according to Kroo. The outline for his presentation at the fifth annual Electric Aircraft Symposium in Santa Rosa, California on April 29, 2011 is instructive. He had three major topics, all repeating the title for his talk; “Design Concepts for Small Electric Aircraft.” The first topic emphasized the word, “Electric,” the second, “Small,” and the third, “Design Concepts.” First he discussed why electric aircraft are of interest, including their environmental impact, efficiency, reliability, energy source independence, and that fact that they are scalable – the latter being important to anyone also designing lifting body airliners. Modern airliners …
