Went back to the launching site yesterday and found the reason for the explosion:

Sky Observer V2 explodes vigorous on the launch pad...See embedded video!

Using a video to JPG converter, the explosion looks as following. All this happens in a split of a second:

This is the second version of my sky observer rocket. The payload containes a 3km range rocket locator and a mini DV camcorder. The rocket is propelled by 3 C6-engines.

The simulated flight plot of the rocket looks as follows:

Since a few months I am also supporting the Sugar Shot to Space team financially and as a volunteer. The underlying goal of the Sugar Shot to Space program is to loft a rocket powered by sugar propellant into space, officially defined as 100 km (62 miles) above the earth's surface. If you want to support this project as well, you can do it here.

Here is a video of the first flight of the MiniSShot rocket in the SS2S project: http://www.youtube.com/watch?v=bQ4Tl4TCi8M

hi MarkusB, neat job!ps, how

hi MarkusB, neat job!

ps, how are you going with your home made rocket propellant motors?

Hi Mikv,Don’t know if you

Hi Mikv,

Don’t know if you saw it, I was at least successful with hexamine and nitrous oxide: http://www.youtube.com/watch?v=opgF9nrIzM8

 

OUCH :frowning:

OUCH :frowning:

Terrific photographic record, though.

Oh man, so much work, just…

Oh man, so much work, just… … !

Cluster Engine/Bomb ?

By your wording “contains” vs. past tense “contained”, I assume that your payload passengers are still hopefully ok?

Is the mixture too vigorous for the venturi? What was the mixture?

Cluster engines would seem to be more difficult.  If differences in thrust occur, and depending on how far the engines are from the center axis, steering could get very “goofy”, yes?

Great Stuff MarkusB !

I will be second in line volunteering as guinea pig astronaut, … um right behind you :smiley:

 

That’s confusing

You wrote about engines, that are bought, not home-made, so:

Engine malfunction?. Maybe a manufacturer mistake?. Bad mounted ignitors?.

 

Tell us about the forensic investigation!.

My bet

is on the lesser know year 2008-bug. Your on-board camera must’ve infected the flight controllers.

I bought the engines, yes.I

I bought the engines, yes.

I guess the grain of the engines got cracks, caused by the high variation in temperature and humidity here in Shanghai. If an engine has these kind of cracks, it can explode vigorous at ignition. I never had this problem before, but now it happened unfortunately on 3 engines.

I will come back to your offer volunteering as a guinea pig astronaut :smiley:

Wow, were those old C6

Wow, were those old C6 engines? Also, do you have the actual flight plot of the rocket?  :slight_smile:

The laugh is always on the

The laugh is always on the loser :stuck_out_tongue:

The problem was Weak paper

The problem was Weak paper O-rings?  Paper blew out sideways? Blowing the other 2 engines into impossible to plot flight paths?

**Failure to launch ! **

Too bad ! Nice explosion though ! Electronics still working fine ?!

Hi Jad-Berro,All electronics

Hi Jad-Berro,

All electronics are fine :slight_smile:

two words

Appollo One.

What type of rocket is

What type of rocket is that…do you know where i could buy one that i could put a camera in like that?

Hi Jaryd,You can order this

Hi Jaryd,
