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. The flat disk (no skirt) was fully exposed above but was recessed into a box with the motor underneath so the bottom was exposed to the inside of the closed box. Lost about a pound of weight when run, which seemed like a lot for such a small gizmo. > > > >I wonder how a freely rotating air-blocking disk mounted on an axle on the underside of a frisbee would affect performance.

Though simply spinning the disk would pull in air over the surface due to dragging from the boundary layer (beta ether again), so the added mechanical complexity of a blower isn't even necessary. Yes, I think I'll call it the "Freely Rotating Intake Surface Beta Ether Engine", or FRISBEE for short." > > > >Cool Rick.
