Please Post VIDEO'S if you got em .

[h&k machineguns]

I am always looking for video's on whistle rockets and similier fast rockets. It seems I can't find much on them. If anyone can post video's here, I'd love ya. Maybe even start a sticky on them.

 

If I were around someone in my area(AZ) that was into rocket motors as much as I have been lately,I probably wouldn't feel the need to ask for video's here,but I feel I have to ask for the video's so I can learn what I want to do for future projects.

P.S. I don't need video's of motors with headers,I just would like to see the launch and air flight.

Post what you have or what you have seen from other links,thanks.

Join WPA. They have this big thing in AZ every february I do believe. You will learn a lot.

I heard it was cancelled this year because of dry conditions. I actually have a few videos rendered from the last week of the 3lb. rockets I made and tested. Unfortunately they are 35-40 MB each. They were recorded in HD, but I transfered them in DV, and they are in .avi now. If I can figure out how to render them in MPEG the file size will dwindle dramatically, but so will the video quality. The sound should stay the same though. I'm gonna try to find a site to upload them to and link to it.

I already posted videos of 4oz whistle rockets in your previous post but here are some 1lb'ers.

 

1lb Sodium Salicylate

1lb Sodium Salicylate-Sodium Benzoate

1lb Sodium Benzoate

 

The first one is a pure Salicylate rocket (I hate these, too whiny).

Second one is 2 increments of Salicylate with the rest Benzoate.

And the third is a pure Sodium Benzoate rocket. These are my favorite, it's almost like they're spitting at you when they first take off, and Benzoate is a longer burning rocket for the same size.

 

and just like before, here's how I make these:

I don't get an effect anything like that from my straight benz rocket, but I'm using strobe tooling. Also, my 3lb'ers don't last nearly as long. Very nice rockets!

I just started putting these on you tube. Here you go:

[ewest]

I've never seen 3lb'ers before, they sound a little like an elephant don't you think? Anyway, nice job.

 

BTW, my favorite is the third video, you managed to film the salute with Old Glory right there in the frame; very patriotic!

 

We have lots of vid's and posts on BP rockets and not enough on whistles IMO, I'm glad h&k started these threads.

[Phildo]

I just got my chems for whistle but here's my BP 1 LB rockets. My camera really sucks at night so you don't get a good idea of the distance in the night time video.

Thanks ewest, the third is my favorite too. It was pure coincidence that we got the flag in the frame on the last video. If you don't get to see to many 3 lb. whistle rockets you are in luck, that's pretty much all I will be making for the next few weeks. I got my Barium Sulfate in today so I'm going to start building strobe rockets too. Great thread HK.

I have never seen a stobe rocket launch yet !

cpl that is an amazing sounding rocket, care to share the tutorial?

[cplmac]

Sure, on the 3lb strobe rocket tooling I basically pressed a long winded screamer. First 1 3/4" was Salycilate whistle mix, the next 2" were Sodium Benzoate whistle mix, the last 1" was the Salycilate mix again and I filled in the last inch or so of empty space with flash. Taped a disc over the top and the motor was ready for stick and fuse.

HK I made that batch of strobe tonight, so hopefully I will get one pressed tomorrow. I'm expecting a KATO however, I didn't have the 200 mesh MgAl so I substituted 250 mesh Mag. This is not going to stobe very well if at all, but I think I might still get the unmistakeable strobe rocket sound, which is a rapid low pitched thumping, a lot like a helicopter. I've heard them called sputter rockets, and that is a more accurate name than strobe rocket. In the meantime here is a link to the video of a test fire I did on a Salycilate whistle insert with Ti.

I have no idea what size this rocket motor was,but I believe it's the best I've seen yet. Just listen to how loud and long that thing goes for from launch to just before the boom. Anyone guess the hight,and size ? I'd especially love to know the speed in Feet per seconds ?

[cplmac]

It sounded like a smaller diameter rocket when it took off, and the whistle itself while long in duration didn't sound deep enough to be very large. But the report sounded pretty heavy. I'm going to guess a 1 pound rocket. No idea on the height. I think I'm going to add another inch of delay to my rocket so I can get the nice long whistle. The core seemed to burn fast on that rocket to, so I'm definately thinking a 1 pounder. Just a guess though, I really have no idea.

Two new rocket videos posted tonight. Both 3lb. rockets, the first is a straight Salycilate rocket (my buddy told me it wouldn't work, so I had to try it) with a large report head, the second was a salycilate/benzoate mix with large mag. shavings. I hoped that laat rocket would give a flitter type effect, but it turned out to be just a really fat Ti looking tail. I mixed a bag of Benzoate whistle with a bag of Salycilate whistle and pressed the mixed comps. Enjoy.

 

 

Also, here is a video of a green strobe comp I used as rocket fuel (that video was unfortunately recorded over) and the video of my second red flash test.

Here is my YouTube channel address, so I don't have to post all these seperately from now on.

Enjoy everyone!

[rocket]

Them vids are great the sound on them is so clear, the reports sound so good. Oh and great rockets as well.

[h&k machineguns]

Oh my,this one was just posted over at passfire.

Best I've ever seen.

3 stage whistle rocket .

[saluterocket]

amazing rocket, i just saw this at passfire allso, i read that the boom was 3.5 seconds from the flash, that says one thing; it whent really really high.

[cplmac]

That was awesome.

[cplmac]

The newest entry. Another 3lb. whistle, really hot mix with a good sputter. The video sucks but the audio is good. I think I could end burn this mix.

 

[a_bab]

cplmac, I just LOVE your rockets. They...rock!

 

In your experience, do you think a mix of sodium chlorate/sodium salicilate might work?

 

Also, can you post some details about how you build your rockets? Maybe a tutorial with a few pics?

 

Thanks and keep up the good work.

[shadopyro]

Not sure whether that'll work but i really wouldnt suggest using sodium chlorate. Not just because its unstable but also because of it hygroscopy (sp?). I'd say whistle mix is sensitive enough as it is.

Thanks! As for the Sodium Chlorate, I have no idea, it's funny you mention it though, I was just thinking the other day that I should try making a batch with Potassium Chlorate. As for a tutorial, I'm not sure. I guess I can bring the camera into the lab and snap some "as you go" pictures, but I would not really want to tell someone to press rockets the way I do because I press them a LOT harder than the accepted norm. I would not want to find out someone lost a hand following my tutorial. I'll talk it over with mumbles.

Okay, new video. This is my first two stage rocket, although it is hard to tell because the first stage did not have enough delay and it passfired about ten feet off the ground. Enjoy!

[a_bab]

Well, if you are afraid of someone loosing a hand, you may want to "hand" me the guidline, along with some pics. I'll be eternal thankful for that. Frankly speaking, I don't think Mumbles will be against posting a tutorial about how to make good whistles, with the right guidlines.

 

The idea of using the sodium chlorate just poped up, because I can get it easier than the potassium chlorate (or perchlorate). I don't think it'll be more sensitive, as the sodium oxydisers tend to be less energetic than the potassium ones. Hygroscopicity on the other hand would pose a problem though.

[shadopyro]

Try google.

Didnt take me that long to find this:

 

http://www.powerlabs.org/chemlabs/deflagrants.htm

(whistle#4 at the bottom of the page)

 

There are many websites that give tutorials on making whistle rockets, including the proper mixing procedures.

If you were adament on using sodium chlorate it with a press, i suppose the added 2% vaseline would help fight off absorbed moisture a bit. The vasline would need to be dissolved in alcohol pror to mixing in with the whistle powder.

[cplmac]

I just melt my vaseline. I'm putting together a tutorial right now on the two stage rocket. sans pressures etc. it's more of a how to assemble than a how to press a rocket.
