Mumbles Posted October 10, 2011 Share Posted October 10, 2011 Any videos or other information on these? I honestly haven't a clue what you're talking about. It sounds like a special kind of whistle rocket though. Link to comment Share on other sites More sharing options...
californiapyro Posted October 10, 2011 Share Posted October 10, 2011 i believe these are a type of commercial rocket available in european/asian countries. am I correct with this? Link to comment Share on other sites More sharing options...
allrocketspsl Posted October 11, 2011 Share Posted October 11, 2011 I never herd of a siren rocket but would like to,most likely a whistle? Link to comment Share on other sites More sharing options...
TheArchitect23 Posted October 11, 2011 Share Posted October 11, 2011 would it be possible to make a whistle rocket, and instead of a core and nozzlemake and equal total size of smaller holes spaced evenly in the clay end plug.i would try this, but im not quite proficient with whistle yet.sounds like it would likely explode, or the clay plug would give out.

californiapyro Posted October 11, 2011 Share Posted October 11, 2011 even if you could make it not cato it probably wouldn't whistle... Link to comment Share on other sites More sharing options...

Anything which restricts the gas flow out of the tube is likely to cause a CATO.  There is a gerb device written up in the PGI anthology made exactly as you describe. Press the comp in the tube, make a solid plug, then drill out 5 small holes, equally spaced around the diameter of the tube just above to the nozzle. Mount it horizontally on your set piece like a lance and enjoy. Link to comment Share on other sites More sharing options...
Mumbles Posted October 11, 2011 Share Posted October 11, 2011 I think you're thinking of something slightly different Nater. I don't have my copy on hand either so I don't know the name, but the idea is that is sprays out 5 streams of sparks in a star shape, sort of like a mutant ground based farfalle. (Don't tell Mike Swisher I just called it that ) From what I got from the description, he wanted a number of vertical vents in the clay plug itself.

nater Posted October 11, 2011 Share Posted October 11, 2011 i see what you are saying, multiple nozzles in the same fuel grain. might look like a cluster rocket from the bottom, but i cant imagine it would work with whistle. Link to comment Share on other sites More sharing options...
Juiceh Posted October 12, 2011 Share Posted October 12, 2011 When you've got a nozzle on your whistle fueled motor, if it doesn't CATO it won't whistle from my experience. So, using multiple nozzle openings in a single end plug probably won't change that. Could a Siren rocket be a whistle rocket that has some smaller whistles attached to it that get ignited along with the motor?? Link to comment Share on other sites More sharing options...

It's mentioned in Brocks book which I believe alludes to the fact that Ruggieri used them about 200 years ago. Link to comment Share on other sites More sharing options...
aftertheaftershock Posted October 13, 2011 Share Posted October 13, 2011 Â The link shows a tannerite siren rocket, I don't think this matches the description listed above. It is a whistle rocket though and well hell it's a rocket with a boom so it works for me Link to comment Share on other sites More sharing options...
Mumbles Posted October 13, 2011 Share Posted October 13, 2011 I can't recall the name either but it's a very old device. It's mentioned in Brocks book which I believe alludes to the fact that Ruggieri used them about 200 years ago.  THe Anthology just calls them 5-pointed stars. He references Kentish, and further looking shows that to be on page 60 of his book. I don't doubt that it goes back farther than Kentish, who was late 1890's. As far as I've been able to tell, Brock's book hasn't been too widely available until perhaps recently. Rugerri is also not commonly referenced for many native english speakers for lack of availability and language barrier. There is an english and german translation available, but whenever I've looked I've never been able to find the English version, or it seems to be prohibitively expensive.
