Fred To answer a question in answer to a question with an answer, I suggest one needs to adopt the Messerschmitt solution which led to the production of the very successful Bf 109, two of which as a boy of 12 I saw flying 50 feet above my head in 1944 (shades of Jim Graham in Empire of the Sun) - in other words, one needs to suck it and see. 8-) Frank >Frank. > >To answer a question with a question. > >What happens to the lift if you use a rotating disk or >blow air over a board with a gazillion holes (blind or through?) in it? >Will rotating your hemispherical spaghetti strainer (fixed plate seal on >bottom?) >add buoyancy lift to the Bernoulli lift? >Banned from the kitchen forever? :-) > >Fred > > >> [Original Message] >> From: Grimer <[EMAIL PROTECTED]> >> To: <[email protected]> >> Date: 1/16/2006 9:12:13 PM >> Subject: RE: Dash Files for LENR Patent >> >> At 08:09 pm 16/01/2006 -0700, you wrote: >> >> I wonder if anyone has ever optimised the Frisbee design >> by doing what Messerschmitt did with the Bf 109 wing, >> i.e. a completely empirical approach with a series of >> small changes and precise measurement of the effects - >> He deliberately made them too weak and saw which line >> of rivets popped first - a process of climbing up the >> efficiency slope to find the top of the hill. >> Of course, there's is no guarantee it's the highest hill. 8-( >> >> Frank >> >> >> >> >Good info, Rick. >> > >> >That might explain some of the reported "antigravity weight loss" of >motors. >> > >> >The 90 ft/sec perimeter velocity on a 12 inch disk at 1728 rpm is >interesting >> >to say the least, if it saw a thrust of about a pound in 0.785 square >feet. >> >Covering "the bottom with something non rotating" as you say, >> >is easy enough, I think. >> > >> >OTOH, a board mounted on a scale with the suction end of >> >a vacuum cleaner or leaf blower on one end and the blower >> >hose on the other setting up high velocity air flow, >> >might lead to an Aero-Hoverboard that you >> >can Surf the Clouds with on Saturdays. >> > >> >4' x 8 ' x 3" fiber glassed Styrofoam? >> > >> >Fred >> >----- Original Message ----- >> >From: Rick Monteverde >> >To: [email protected] >> >Sent: 1/16/2006 6:49:49 PM >> >Subject: RE: Dash Files for LENR Patent >> > >> > >> >Fred - >> > >> >Cover the bottom with something non-rotating. >> > >> >I built a small centrifuge a while back for casting small plastic parts >with thick resin, 1728rpm motor, disk 12" or so in diameter.
