Electric Paramotor Experimenter
How much can be done with any given amount of weight? How long will the power last if pushing at some amount of thrust? How much will it cost? Most of these answers can be derived with a knowledge of batteries and electric motors and propellers but the calculations can be tedious at best. Mark Deseck, paramotor pilot from Michigan and electric propulsion enthusiast, designed a graphing spreadsheet that lets users tinker with the possibilities.
Of course reality will easily get in the way with losses in the processes but many of the relationships are purely mathematical: you can only suck 1 amp out of a 10 amp-hour battery for 10 hours, for example. To produce x amoun..\Developments\yuneec\index.htmt of torque requires y amount of current at z voltage, etc., etc. This spreadsheet lets you play with the possibilities at will.
Jerry Coleman of North Carolina has years of involvement in sport parachuting, then powered paragliding and now powered paraglider triking. He is enthused over the possibility of electric PPG and has offered his knowledge of Lithium Polymer batteries, brushless DC motors and controllers (for throttling) to anyone working on developing an electric paramotor. To contact him, please email firstname.lastname@example.org with "Electric PPG" in the subject line.
They're all experimenters right now. Although at
least one well-funded group toils to perfect the application, most are spending
their own money. Our hats are off to those who work on it in the face of a
relatively small market.
