Launch report 12 march 2011 740feet/225meter

Hi,

Today we launched our new rocket posted in the previous topic. It is a 9,1L rocket and we launched it at 12 bar.
Everything went wel.. exept for the parachute bungie cord.. it snaped.. and the rocket was free to go back to the earth fast :-( The bungie cord was to old perhaps that causes it to snap. We have some rebuilding to do.. the top section has a leak and its smashed like an accordion..

altough a nice view at 225 meter by the md80 clone. On the next flight we are going to remove the time stamp. rebuild the rocket and launch it at 14 bar. To get over the 250 meters!

What size nozzle do you use on that rocket? The liftoff speed looked pretty high for a rocket of that volume. Nice flight! Sorry you had problems!

its a 21 mm nozzle

its a 21 mm nozzle

So that would be a full size bottle neck opening with what would likely be a cable tie or similar launcher. You put that thing up there for sure! Good job!
