50mm diameter, KN/Mannitol powered rocket flies to 4473 meters.wmv

Was looking at your video title, thought i saw 4473 feet. But when i saw the takeoff i looked again and realized it was meters! What a rocket!

Propellant is standard 65/35 mix (65% potassium nitrate, 35% mannitol)with 0,1% of surfactant added.

Holyshit what the hell is the formula ratio are you using?

[GabberJunkieZ]

Zanima me kje si dobil višinomer. Vsekakor pa čestitke za tako uspešno raketo.

Super raketa!

Šla ful visok.

Moja je pa letela rekordnih 30m.

this video rocks. mannitol is not a sugar, is a polyalcohol and this shows it contains high power in it.

No wonder why mannitol hexanitrate is so darn powerfull.

[Andre09091978]

Because it is totally non-hygroscopic, burns slow even at high pressures and has very good adhesion to the fiber liner that I use.

[creimers84]

I was going to ask that question too, great answer thank you.

is the propellant grain any harder to produce when using mannitol then other sugars?

[slither888]

Nice, but why mannitol? It is expensive and there are many other cheap sugar substitutes

[Peterditaa]

AWESOME!

Sjajno Andrej,

Pozdrav iz Beograda od Srdjana.

Zao mi je sto nisam bio, imao sam stosta da ispalim ali me niko od ovih mojih nije ni obavestio o smotri a dobili su zvanican poziv i vrlo dobro znaju da sam ja i jos jedan covek jedini koji nesto ovde radimo na tu temu...

Inace, kako ti prenosis to preko granice, da li prijavljujes ili se pravis kao turista. Gde nabavljas taj manitol i kakav je postupak mesanja ?

[stone4x4]

Great flight! Looks like you got a really nice propellant there!
