inertial propulsion with gyroscope

[woopy]

Hi all

I found some steel balls and a light flat structured cardboard plate.

So i  looked for a flat and smooth enough surface in my house to make some first crude "marble" test.

As expected there is dynamic torsions and drift because the device is not a twin device working dynamically against each other but allowing the main forward movement.

So i made a short video, where you can see that there is always a main forward direction of movement.

I also made a test on a not perfectly leveled surface (the steel balls roll down the very very gentle slope ) and to my great surprise, the device could coast.

Something interesting is that the drift movement tends to deregulate the device, and i had to increase slightly the diameter of the traction wheel to get the device working correctly on the marbles.

Then with the same traction wheel, i reinstalled the ballbearing wheels and redo a test by rolling (no more marbles) , and in this case the systems spins too fast and the traction wheel touch the ring track all along so there is no more gyroscopic precession on any  location around the 360 degre ring and the device move back and forth without any directional displacement. To get back  the forward rolling movement, i have to decrease the diameter of the traction wheel or decrease the spinning speed of the gyro.

Very sensitiv device indeed, but so a lot of fun.

Of course these test are "crude" and not made on perfectly smooth lab surface and probably my steel balls are not perfectly round. But to me and so far, the movement stay there. So i encourage replicators to redo all those test before going to any conclusion. We are so often fooled by unattended artifact that we have to be very careful especially with such sensitiv topics.

Hope this helps

the 4 gyros inside the rotating container seem to be fixed on the bottom. So they can not precess.

Yes, they are bolted down. but remember that the base plate must be made to rotate (which is not that easy).

  it moves with great speed !!
if you start it in the spot where it ended up [against the furniture]

and point the front drive  180 degrees towards the old starting point
will it travel the same line towards the old starting point [by the carpet?] [or is this the coasting you mention?

This sounds very familiar , the 4 Gyro's were fixed vertically and NOT allowed to angle up in precession and as a result  were lifting the Plate they were attached to ... as the 4 gyro quad array was turned toward precession.

Yes !!

I do believe a had seen this Video too, along with weight scales and a claim.

gotta try that one !!

and as Laurent has mentioned this could be inverted to put weight on the scale too?

There are two perspectives, and both are correct in their own right.
In one, the force can only be on the entire assembly, and not on the inertial frame
of the gyro. This means that the force cannot be used to apply external motive force.
like two guys on a boat on a sliding platform, trying to push a wall to move the boat forward.


In the other perspective, the force represents itself along the axis in one or two of the perpendicular
dimensions, depending upon the applied force and the angle of the force to the angle of rotation.
This can manifest itself as a tangential-force vector.
applied to the axis.
If the axis itself is free to move in space, and precession interrupted appropriately, the result is
a linear momentum.


to truly direct this becomes tricky.
The gyro boat inventors used an additional motor to rotate the
platform the main axis was mounted to.
This allowed them to "steer" the linear force. (kind of)
what they learned indicated that the linear force has also a vectored component, from the rotational
momentum, and by steering it in their manner, did not give full control over direction.
but that it can be directed, if the variables are identified.
which we now know how to do,
If a modern-day attempt to construct the gyroboat were made, it would probably be quite an interesting
thing.

Hi all

As TK made a very interesting comment on my video

i did  make his proposition

and so i reinstall the ballbearing wheels on the device and  place the whole system on the cardboard ( which as been replaced by a stiff and very smooth aluminium plate )

and all of the system  "floating "on the steel balls

Of course it is very difficult at technical level  to be very accurate. So please take all this stuff as simple experiment and not as established fact.

But perhaps as TK  seems to have made all this experiments long ago perhaps he could help us and show some of his experiment and results.
