The talk was presented at the July meeting of the Texas Flying Club (<a href=\"http:\/\/www.texasflyingclub.com\/\">http:\/\/www.texasflyingclub.com\/<\/a>). As a general guideline, the audience was comprised of pilots, such that the mathematics and physics are not presented as a formal proof but presented with the intent to convey understanding. One key point made is that any discussion of aerodynamics concepts must be consistent with continuity of mass, momentum, and energy. A simple freestream, source\/sink, and vortex model was presented to explore a consistent understanding of aerodynamics for aviation. <\/p>\n\n\n\n<div data-wp-interactive=\"\" class=\"wp-block-file\"><object data-wp-bind--hidden=\"!selectors.core.file.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/charles-oneill.com\/blog\/wp-content\/uploads\/2025\/07\/AeroLiftMyths.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"Embed of AeroLiftMyths.\"><\/object><a id=\"wp-block-file--media-b5edd364-a360-4b0f-a1ff-a490842b7f85\" href=\"https:\/\/charles-oneill.com\/blog\/wp-content\/uploads\/2025\/07\/AeroLiftMyths.pdf\">AeroLiftMyths<\/a><a href=\"https:\/\/charles-oneill.com\/blog\/wp-content\/uploads\/2025\/07\/AeroLiftMyths.pdf\" class=\"wp-block-file__button wp-element-button\" download aria-describedby=\"wp-block-file--media-b5edd364-a360-4b0f-a1ff-a490842b7f85\">Download<\/a><\/div>\n\n\n\n<figure class=\"wp-block-pullquote\"><blockquote><p>One Vortex to rule them all, One Vortex to find them,<br>One Vortex to bring them all and in the darkness bind them<br>In the Land of Aerodynamics where the Myths lie<\/p><\/blockquote><\/figure>\n\n\n\n<p>Update: 1\/30\/2026<\/p>\n\n\n\n<p>The use of potentials in the above aerodynamics analysis is mirrored in the use of potentials in more theoretical physics.
