Well for example this report: https://repository.asu.edu/attachments/97903/content//tmp/package-ufqfxU/Peshlakai_asu_0010N_12439.pdf It gives rotor efficiency of over 90% witch is really good and it is also in line with other reports and pages i have read, but still the overall efficiency is...

Hi. I have read about Tesla turbines. What i have found is that it is actually weary little research published on the subject. And as i understand it the main problem with them is the inefficiency in the nozzles used. While the turbine rotor efficiency in it self is really good. But what...

That is what i am after. But i don't particularly like the track and cam idea (but that is the same possible mechanism that was the only one i could think of too). I like a linkage mechanism better (more robust and simple). And the switchover mechanism (for selecting between the two tracks in...

That is what i have tried in post #3 The bistable mechanism is not in the drawing obviously because that is what i am asking for. But the bistable mechanism will be in the center of the plane that is moving up and down the linear axis, and will change the angle of this plane on each end position...

As i said i have a force driving it, but the problem is that the force diminish to zero right before the midpoint where the switching takes place. If we assume that the plane has sufficient mass and speed the inertia will fix the problem by overcoming the spring force and carrying it past the...

How does that have any relevance to my question?

I tried to draw what i am trying to achieve: So the plane (1) is moving up and down the axis (the vertical filled box) and flipping the angle of the plane at each end of the travel. The plane that is flipping is driven with a force up or down when it is angled, but when it is flipping it will...

For my application i can only have one driven part, so that does not work. I am thinking that somehow some joint that moves the "unstable position" must flipp over at the same time as the whole lever flipps over. My application involves a oscilating part that will change the angle of a plate on...

Hi. I have a application for a bistable spring mechanism. But my problem is that all of the ones i have seen require to go past the "midpoint" before it flips to the other side. Is there any such mechanism that flips over to position 2 before you get to the "midpoint" from position 1? Example...
