hondo Posted April 29, 2009 Share Posted April 29, 2009 check out my new projects, turbillions, made about 12 so far and they work great, just like pressing end burner rockets but drill 1/8 inch holes on each end oposing each other at about 45 degree angle, I go to lowes and get paint stir stick for the wings, cut them about 4 inchs long, hot glue on, quick match the holes together and visco for the main fuse, lay on ground, lit fuse and run, now trying variations. like colored comp in the middle so it turns colors at the top of flight and one with about 2 g of flash for a finalie Link to comment Share on other sites More sharing options...

hondo Posted April 29, 2009 Author Share Posted April 29, 2009 my book calls them tirbillions, and no I dont have a video yet but will make one soon Link to comment Share on other sites More sharing options...
FrankRizzo Posted April 29, 2009 Share Posted April 29, 2009 Very cool, Hondo. Not sure of you know this or not, but you don't need to angle the fins on Tourbillions. The "wing" effect is really negligible. Simply having the stick straight across the top of bottom provides a stable base for the spin to start straight.. The bottom vents provide all the lift.

psyco_1322 Posted April 29, 2009 Share Posted April 29, 2009 Z-bombs are basically single or twin ported stinger missiles. They launch standing up and are spin stabilized rockets, no wings or sticks attached. The difference between them and stingers is that stingers get there lift from a bottom port and the Z-bombs don't have this bottom port rather the side ports are slanted downwards, providing lift as it spins.

Arthur Posted April 29, 2009 Share Posted April 29, 2009 My understanding of a tourbillion is that one is launched like a cake insert with a lift charge and it spins on the way up and at the top. Link to comment Share on other sites More sharing options...
FrankRizzo Posted April 30, 2009 Share Posted April 30, 2009 Unfortunately there is a lot of terminology that gets confused in pyro. What I call the cake inserts is a z-bomb or a whirlwind, but I've also heard them called tourbillions. My definition of a tourbillion is a device that has two opposing vents on the ends, and two lifting vents on the bottom. Link to comment Share on other sites More sharing options...
hondo Posted April 30, 2009 Author Share Posted April 30, 2009 didnt know about the wings that they could be straight but here is the link to the movie http://www.youtube.com/watch?v=ahzogTMRmAU Link to comment Share on other sites More sharing options...
Mumbles Posted April 30, 2009 Share Posted April 30, 2009 Looks very nice. A bit of coarse Al, or charcoal would really add a pronounced effect I think. A very nice umbrella like spread. Link to comment Share on other sites More sharing options...
hondo Posted May 1, 2009 Author Share Posted May 1, 2009 yes next few I make will try adding some al or charcoal just wanted to make sure I had the design right before trying different things Link to comment Share on other sites More sharing options...
