[time-nuts] OCXO sensitive to gravitational effects

[Lux, Jim (337C)]

More realistically, it's not that hard to simulate 2 G

9.8  = V^2/r  or (2*pi)^2*r*rotation rate^2.  Say you have an r of one meter (should fit conveniently in your garage)...

10/12 /1 = rotation rate^2...  About 1 rev/second -> 60 rpm.  12 m/s tangential velocity.

That would actually get you sqrt(5) = 2.23 G

For comparison, airplane props have a tangential speed at the tip close to mach 1.. 300m/s, are about 1 meter radius, and turn at 2400 RPM.

It's doing zero G that is a challenge.. A big drop tower works.

   18011 oscillator... one G this way... two Gs the other way...
   Here you can see the result of some serious Gs, all applied at the same
   time...
