“Older and contemporary attempts for inertial propulsion”

“A device that can produce net impulse using rotating masses”

His work makes one wonder "do gyroscopic principles hold true for 'partial' gyroscopes?
Looks like you don't need a full flywheel...

 An interesting post. Is the (home/chronos/u- etc) supposed to be a link? Gyroscopic principles do exist for partial gyro rotors and can give some useful effects for manipulating angular momentum.
You do not mention conservation of momentum. Deliberate omission or an over-site. Gyroscopes are not the exclusive method for producing asymmetric thrust.
Well worth a more detailed read.

 Nate;

Anybody home?

Sandy vouches for ya.

Same question as Momentus.

(file:///home/chronos/u-a8...); is a file on your computer?

 Sorry. Here's the link to download the pdf.

Also, I found an even more interesting report relating to patent US2008/0223636:

The first link shows only a computer image of device. It appears to be an open device, which brings up questions about the geometry of the "masses" and their varying aspects to the atmo in their figure eights and the airflows generated by their motions. If it is an open device, then the possibility exists that the "thrust" could be entirely to do with airflow generated by the masses motions. Apart from that consideration, I would be concerned about averaging out positive and negative values generated by flexing rods and other non-rigid members.

Do you have any info if it has ever been done completely enclosed?

The second link for Patent? was blank.

 Dave-

No, I haven't found any evidence that Provatidis has tested his devices enclosed. I wonder why he doesn't simply put one on a scale. I did, find value in his math that predicts a net lifting force.

My approach involves a combination of gyro forces and eccentric mass forces. All of the references I've found use only one or the other and I don't believe symmetrical systems will ever release the forces we're seeking.

Right now, I'm struggling with the PTO over the formalities of my patent application - very difficult indeed (even with a patent attorney).

I have a number of devices in mind and have noticed that any departures from "unbalanced" , tends to "balance" the effect out of existence.

I have to put a "thumbs down" on discussed device until it has passed the "enclosed test".
