single bottle height
Hi all!
for my research competences we launched single bottle rockets (mor info in another topic; named project week). our highest was 40 metres with 7,5 bar. I know that's not high, but I want to have a reference. So what is your highest altitude recorded with a single bottle?

Re: single bottle height
Congratulations!
I had a 1 liter bottle hit 250ft at 100psi. So about 76 meters, just under 7bar. Don't think I had a camera in at the time.

Re: single bottle height
Ours was a 1,5 litre bottle, but it weighed a lot. I think that is our mayor problem

Just checked mine, I think its "dry" weight including the ballast, was ~240g, 151g without the ballast or altimeter.

Re: single bottle height
Mine weighed about 600 g and the weight distribution isn't optimal: the cage for the wings weighs about 250 g , our altimeter weighs about 100 g and our parachute+ cover weighs about 70 g. I'll try to post a movie later on.
TO EVERYONE:
please do post here. It would be very handy

Re: single bottle height
What is all this metric rubbish??
I often use this simulator to get estimates on about how high my rocket either went or should go: http://cjh.polyplex.org/rockets/simulation/
It works great and has been tested with a altimeter.

Re: single bottle height
143g is the target weight for pinewood derby cars IF the official scale only measures to tenths of an ounce. (5.04)Blenderite wrote:What is all this metric rubbish??

So when measuring small things or where more precision is needed than ounces, I find it makes more sense to use grams. Also for international comparisons, we're the odd duck out.
