E- M a il PUBLICATIONS STAFF The Wright Flyer B Accident I mentioned this to Chad [Jensen] in a phone conversation, [but] even with flawless welds I suspect the prop shaft design [of the Wright Flyer Model B] may have been lacking in the failure area considering the engine horsepower, two chain drives, relatively large prop diameters, substantial associated rotating mass with the possibility of opposing resonant frequencies, or just inadequate even for synchronous engine/chain drive/prop frequencies. I am not a professional mechanical engineer, just an old A&P;/IA lifetime shop guy. I would love to hear an engineer's take on this, if you come across one. Hopefully, if my comment proves out, it would be passed along to members in print, for their consideration in similar applications. Steven L. Dawson EAA 60588 Steve…we're printing your letter in case some engineers want to weigh in on your observation. .. Ed. Love Experimenter! Love the digital EAA Experimenter! Crisp text and vivid photos, and I can read it anywhere and keep it for future reference. I [download a PDF] typically to read it on my iPad mini because I can open it anywhere, unlike carrying a magazine with me. The photos really pop on the retina display. I estimate I read about 80 percent of each issue. Bern Heimos EAA 538444 Thanks for the kind comments, Bern. Glad you're enjoying the digital issue. – Editor How do you read the digital Experimenter?
