You're right, I should have written "thrust implies a sustained acceleration (a sustained force)".  Imagine Woopy's rowing device on an air table; the device would move to the right, let's say, then stop. even though there was essentially no friction. Then with the next cycle it will move again to the right, then stop. There is positive acceleration at the beginning of each cycle, counterbalanced by a negative acceleration at the end of each cycle, with no acceleration in between cycles. Maybe engineering can get around this, I don't know at this point.

According to the 2nd law, any acceleration implies force.
In this case, thrust in one direction exceeds thrust in another, this is why it eventually moves in the direction of a higher thrust.

It is interesting that the turning of the arm carrying the spinning gyroscope (in the horizontal position) does not impart a back and forth movement of the little wagon. But once the gyroscope becomes dead weight (because the spinning stopped) the rest turning movement of the arm does well impart some back and forth movement.

In the last weeks I had almost no time to continue with my gyroscope experiments and that will stay like this for while.

Greetings, Conrad

Hi all
Sommer is almost past
So back to shop for some new discovery

Excellent tests. Attached images are what I think is happening.

Assuming the blue arrow is the direction the gyros are spinning, red arrows are the force applied to the gyros, green arrows are the resulting movement of the gyros.

Image one is what I think is happening in your system. Figure 1 happens first, which is an unnecessary step, causing figure 2 to happen resulting in the desired forward motion you have.

Image two shows possible tests of this. Figure1 has the gyros vertical movement pivot point removed. Movement force can only be applied forward and back, resulting in the gyros moving up. You should see basically no forward movement of your system. Figure 2 is the most efficient method of moving the system forward I think. Have the gyros pivot up and down only. Quickly move them up and slowly move them down.

To sum it up. We only need to apply up and down force to the gyros. Up quickly and down slowly. You can accomplish this directly with the servo.

Hi Magna Prop
Thank's for your interest.
If i understand you well in simple vertical oscillation of the gyro but at different speed should also induce a forward movement.
I am not so sure, because if you don't get the inertial asymetry between the back and forth stroke, as per Fiala's patent, i suppose that the gyro will be very similar to a dead mass, i mean when the gyro wil raise up quickly, you will get a quick forward movement and then when the gyro descend slowly you will have a long and slow backward movement.But with those gyros never knows, they are so unintuitiv.I wiil perhaps make a test later, because i have almost no more matos at the present, and i have decided to no more dismantle a working machine to test something new.But i have already ordered a bunch of small gyros and motors and servos to test different config.
Of course feel free to test yourself and please report here you results
Regards
Laurent

I believe so.

It isn't quite dead mass in that the 90 degree force on that gyro mass is in the direction you want your contraption to move. Perhaps in space you might be right about the long and slow backward movement. The small amount of friction your system has might be enough to counter that and keep it moving forward but I'm not sure.

I agree, definitely do not dismantle your working prototype! How many times have we heard the "I had it working but changed some things and now...nada".

Hope I can get some time to try something but I'm stuck at the moment trying to get a 32 bit drone off the ground. Very frustrating.

Keep up the great work.

Very cool experiment. But I'm not sure what you are saying. Are you winding up the wire it is hanging on?

I wonder if you spin up a gyro assy then threw the assy up into the air if it would just go up then back down just like any other object, or would it do something else. If it does something else.......
