My Beginning in Whistle Rocketry

[Mumbles]

Ok Stinger, being a moron and making completely unsafe rockets on your own time is one thing. It's obvious that you're not going to change your ways despite frequent warnings. Giving terrible advice like that is another. I'm not fucking around anymore. If you don't shape your game up, you're banned.

 

Now, chemically speaking, chlorate is a weaker oxidizer than perchlorate. However, chlorate is much more unstable than perchlorate. As such compositions made with it light easier, burn faster, and are more sensitive. There really is no reason to use chlorate whistle. Perchlorate based whistle is unstable enough, tossing chlorate into the mix is just asking for trouble.

[Stinger]

Mumbles I dont want to offend you, but I know another guy who uses the same materials that I use and

he is doing a very very nice job on whistle rockets

I DID NOT say that I used chlorate whistle in the previous post, did I?

Many people use chlorate whistle, Cplmac for example, doesnt he?

You will not expect it but I think I will never use chlorate whistle despite of your opinion on me being a complete moron

Why are you nagging about me if I follow all the safety warningss, except using PVC-casing for whistle?

I tought posting videos of someones first success is accepted here, but just because of using PVC-tubes for whistle rockets its not?

As you might have seen the rocket didnt even CATO by the way.

 

I dont get the point, really.

In the future I wont post any videos again because its really not worth it.

 

If you´r nagging again, do it, thats my point of the whole story right here, it might be easier for all of you in good old america when

it comes to pyrotechnic stuff, but here its different.

If you want to ban me, then do it, but I am sure there is a way out

[Mumbles]

I never said it cannot be done, PVC or chlorate whistle or otherwise. The problem is neither are very safe, especially if you have little experience. Cpl for instance has plenty of experience and appropriate blast shields and all that. In case you haven't seen it, he's also had a whistle rocket explode on him while pressing it. That was perchlorate based mind you. He has experimented with it, but the vast majority of his rockets are perchlorate based. Chlorate whistle is unnecessarily sensitive.

 

The problem was not that you said you used chlorate whistle, but essentially were suggesting that this other gentleman use it, particularly without offering any safety warnings or information. Like I said before in slightly harsher terms, we just can't have that.

[Stinger]

Okay, I´ll accept that , so we´re done then

Today Ive been working on some decent whistle tooling, I have made a 1lb pusher core tool using

my dad's lathe. My whistle mix is drying so tonight I will test this thing out.

 

 

The tool is a replica of the 1lb pusher desing from this site: http://www.wichitabuggywhip.com/fireworks/...rich/index.html

I don't see why everyone keeps making pusher tooling. I see it as nothing more than a waste of tube with its huge dead space.

[firetech]

I think its the difference in sound that they like.

[FREAKYDUTCHMEN]

And performance.

[psyco_1322]

My standard 4oz spindle is over a 1/4" long than the pusher, its doesnt waste an inch of tube and its still screams and whistles.

 

Anyone running 4oz pusher tooling? Lets have a weight lifting contest or something, we can see what really works and what doesn't. Or we can even play on the 1lb level. I'm game, lets do this!

[firetech]

Lets see your tooling so we can compare the two.

[psyco_1322]

The spindle on the right is what I use. The left is my older one, which I have another made all in one piece of solid brass, these are bronze spindles. I still need to remake it, its not hot enough, the length and diameter of the spindle needs to be increased.

Whoot! I got some new tooling, whistle mix and a whole lot of bad luck on my side! I just know that I will win in in the CATO and DUCK! categories.

[firetech]

Very shiny...and nice looking. How'd you put the base, tube centering piece and spindle together?

[psyco_1322]

Its kind of odd. Notice the bases in the picture are the same, only the spindle is different. The nipple piece is just in a whole I drilled in the block of wood. Under the nipple is a small washer that the spindle sets on. The nipple has a whole so I can just swap out spindles of that diameter. They just fall in, nothing more. Nothing fancy on the non fancy base.

 

So like this: hole in wood>washer in hole>nipple in hole>hole in nipple>spindle in nipple

[firetech]

So you have to pull the spindle out at the end?

[psyco_1322]

Yes, it just lifts out, I clamp the spindle end into a vise, give it a twist and the motor comes right off.

This is 24mm ID whistle rocket I launched today. It was quite powerful and I loved the sound, but I have one question. How can I make the rocket flight straight up and not at the angle? I used one stick for stabilization about 10x10mm and 90cm long, do you think it was to short?

[dagabu]

That is a common issue with high thrust rockets. The thrust spike pushes the motor against the stick and it starts to go off at an angle. Use two shorter sticks, 180° apart from each other and you will have better flights.

 

Sweet sound and nice long flight! You may wish to put some kind of indicator of end of flight such as a report at the end.

Or put some weight on top of these overpowered rockets, even with a 800 gram header it will fly 400 meters high. And the stick could also be a bit longer and maybe a bit more in diameter.

Nope, not on the long winded screamer, it would turn around and plant itself in the ground once the thrust phase was finished.

[FREAKYDUTCHMEN]

Where did you read it's a lws?

[dagabu]

Where did you read it's a lws?

 

Really? Seriously? 15 seconds of whistle is not a clue?

 

There is no thrust worth a darn in a flat whistle grain, what would be providing the thrust that would keep the rocket flying? A heading would turn that rocket back around somewhere around the 5 second mark, the rocket would take about 5 seconds to come back to the ground where it would sit, planted nicely in the ground until it popped the heading... if it wasn't torn off by the impact with the ground first.

 

But hey, that just my opinion, I may be wrong, it could work. Freaky, why dont you demonstrate the way it works?

[Zmuro]

Hehe, I know that I should use less fuel over the spindle when I will put a header on it. This was just a motor test to see if it will cato or not because of a long spindle.

[FREAKYDUTCHMEN]

I already have experience with this type of rocket, no need to demonstrate

Pressing 15 seconds delay in whistle rocket makes it a lws?

 

"what would be providing the thrust that would keep the rocket flying?"...

Kinetic energy, the core burns like hell, thats why the rocket takes of with an angle, it can't put all it's energy into the material of the rocket, that's why it makes some extra movements.

I did a test a while ago with a 800 grams brick as payload, it flew for about 8 seconds into straight vertical direction, it landed about 25 seconds after take off.

This would be a great signature for you hehe...

I have the same tooling and lifted a 4inch shell on it no problems with basically the same fuel,I'll be lifting some 6inchers in the next few weeks,I found that long delay strange because mine only whistle for half a second,pyrozmuro did you use a full 10 inch tube to get such a long delay rather than trimming it to the dimensions of the p.v.c case support sleeves.
