inertial propulsion with gyroscope

[woopy]

Hi Hanelore

It is freeday in my country , and bad weather, so i decided ti give a crude go to this "Nasa's" pendulum test.

As i thought, there is a lot of wobling, so the motorising effect is not at max for sure.

At the end of the video the pointer is somehow partially stabilised, but always pendels a bit, so i don't know if the test is of any relevance.

To me the test on the marbles (part eight) is much more interesting, because we can study the device and its behaviour in details.

Just for your info as your are new in this forum,  i have no commercial interest in inertial propulsion system, and i do it only for my pleasure. And frankly said  , the motorising effect is so weak that i see no possibility for a practical use on this planet, and this Fiala's flat system is  gravity precessed so they does not work in space. And as i have no connection to Elon Musk for developping a forced precessed device whych could go through space at supraluminal speed my hope are very short. But who knows?

And my pleasure now will not be to prove to you or anyone else something, but to share info and eventually go deeper in the understanding of gyros when they spin and precess.

The gyros are fascinating,..... are they more??

So back to workshop

Interesting video https://www.youtube.com/watch?v=t34Gv39ypRo (no weight loss when a gyroscope is precessing)

Wild contraption that does not work https://www.youtube.com/watch?v=gwh2vGudeLk (there seem to be some people who experiment, but it is not easy)

Even wilder https://www.youtube.com/watch?v=gQs0FtjUj1c

@Laurent: your pendulum test https://youtu.be/CCN2cWNFVWA is not so bad for such a slowly turning "space drive". I think with two drives and a bit faster turning of the arms it would stay on one side of vertical.

Greetings, Conrad

Hi Laurent,

thanks for the video with pendulum test attempt, but
without parallel line pairs it is not Nasa pendulum test.

In your test lines go up conically and allow rotation about transverse axis!

The machine in traction phase causes a torque parallel transverse axis,
which becomes visible with lines going up conically.

I made a scetch for Nasa pendulum test in your room (see attachement) and
with such an arrangement the system can not rotate about transverse axis.

Gyros are indeed fascinating!

Thanks for all your efforts, Hanelore

Hi all

A new member "shadowbones" is trying to post here but he could not and he PM to me. here is the paste of his PM.

  "Sorry, woopy, I'm stumbling around trying to learn the forum site.

My attempted post for a couple days ago is still in moderation. Basically, I pointed out that since your method doesn't create sustained acceleration, the NASA pendulum test is not appropriate.

Also, I asked if you have good suggestions about where to get small parts for experimentation, including the fidget spinner you use. Years ago when I last tried some of this, I used a company called Small Parts (in the US)  but they are no longer around.

Thanks,
Kevin "

So Kevin i hope you will be approuved soon. Just for info the spinner i use come from Banggood china. I insist on the fact that the weight of a good gyro for our purpose MUST be in majority in the rim of the gyro. So the spinner i got are not the cheaper, but they work so well and they can easily be combined up to 5 together. Ref at Banggood "
_{EDC motif circulaire Fidget Creative Fingers Entre spirale Jouets Gyroscope ronde réduire le stress.}And chose the version with the smooth ring.
They also have 360 degrees servo if you want to replicate some of my experiment, so we can discuss the results.
Hope this helps
Laurent

I conrad

Yes nice videos

My comment on the first one.
This guy make a totally wrong test trying to debunk Prof Laithwaite. He should have much better spend his time and money and build the big wheel as Another debunker "Veritasium " did, and discuss the result. He would have learned something. It is somehow similar to the students (i mentionned in part 16) at Imperial college that jump on conclusion with incomplete experiment. Pathetic !
And if you notice, all these people use the famous HIGH PRECISION gyro from England, with a lot of dead mass all arround the gyrowheel. This gyro is certainly a very good school object with a lot of gimballing possibility, but probably not the best one to replicate Laithwaite's or Fiala's experiment. The big wheel is only one big gyro and a pole, if it was surrounded with lots of heavy protective dead mass, i am almost sure that Laithwaite would have been "centrifuged" against the wall and would have missed the remarkable effect.

The 2 other videos are good attempt, but with poor material. If you look at Sandy Kidd latest video https://youtu.be/ExCC9zZeZuY, you see that another time the gyros are "nude" (no dead mass) at the end of the shaft. And the device is very solid. You know very well how strong those gyros react when they are forced precessed.
And Sandy has the speed controll of the spinning gyro and the rotation with RC.

And for the Nasa's pendulum, Hanelore say that it is not correct so let's assume it is not a Nasa's pendulum test et voila.
