Ok. I am going to calculate an approximation to the resonant frequency of a dynajet petal valve using my 'strip valve'. The reader may find the final result, surprising, as I did.

I needed some dimensions concerning the dynaJet's petal valve geometry. They aren't on the drawing so I redrew the parts that I needed.
• The 'flat' of the retainer dictates the 'free' length of the petal.
• The red outline shows 1/2 of the petal valve.
• The rectangle, of course, is the 'strip'. I'll show you how to deal with the 'left over', later.

Just a little bit more background before we can start 'plugging and chugging' ...

Hi GRIM,

I am glad to read you're enjoying the thread and are able to follow along. I promise, more curiosities to follow. This model incorporates and makes clear many things I have read that were not so clear, when I read them.

With a 'handle' like GRIM, no wonder you like the 'binary reaper'. I am not the originator. I saw it for the first time on the Internet somewhere, many years ago. I do not know the artist's name. I was so intrigued by its conception ... and had no clue then how to draw it. I do now. This is my rendition from memory of the original. I used PSP and 'masks' and 'noise'.

I wear 'hoodies', stare at computer terminals a lot, and live in a world of 'static' at times. The animation ... is me.

### Re: dynamic modeling of a strip valve

webpilot I just wanted to say That I think i may be "that guy" you got the concept from. Its been a handle of mine for years, and I am quite active on the internet in a number of ways. I goggled "BinaryReaper" just out of curiosity and found this page, and felt I had to say something. I agree with what you have taken from the concept completely, and I view it in much the same way! I am sorry if this post seems pointless, but when I saw this page I just felt an impulse and acted on it.

Keep the tag alive.
