Anyone ever modelled a whistle?

I'm trying to incorporate a pneumatic whistle in a design I'm working on
(driven by CO2 cartridge) and I've been looking around the Web (with no
success) to see if I can locate a drawing of some geometry. What I'm
hoping to find is something like a police whistle or recorder (flute)
geometry. Anyone ever done a whistle like this, or have seen such a
model?

See my Web site for a valid email address, or just post a reply (please
don't POST my email address while trying to send me a message -- I get
enough spam as it is).

TIA

I've seen drawings like this for pipe organ pipes. Can't remember
where, it's been a long time since I had that hobby, but they do
exist. Same principle so it should work for you .... you also might
look for a cross section of a steam locomotive whistle. Railroad
fanatics are common and I'm sure you could find that pretty easily.

 

here's a few -

I'm sure there's many more ....

 

or better yet, contact this person :

(i think you'll have to slow down the pressure of a CO2
cartridge, tho. Most whistles and organ pipes deal with
low-velocity high-volume airflow.)

 

nah, but I've whistled a model.
