While it would reduce surface friction, angular winds on the holes might cause air to curl up and stack up inside the cone - building up pressure inside and increasing the chance for the cone to flip over. The point of the cone shape is to increase the pressure differencial on the outside and push the cone down.<BR/><BR/>If I were to change some details on the probes I would taper the top and perhaps attach some kind of rubber skirt to create the best possible seal with the ground.Eric Carlsonhttps://www.blogger.com/profile/17569775025253693573noreply@blogger.comtag:blogger.com,1999:blog-20177520.post-65994183225335765832007-04-12T14:37:00.000-06:002007-04-12T14:37:00.000-06:00i'm trying to figure out aerodynamically if it mak...i'm trying to figure out aerodynamically if it makes sense to put ventilation holes in the cone to equalize the pressure from the underside of the cone to the top (or even create a slight vacuum due to venturi effect over the holes).
