about the empty space for blowdown mode, its actually the exact same principle as for water rockets, around 33% is the most optimal amount of water compared to air, more water and it will lose thrust fast, less water and it will run out of water sooner without as much deltaV gotten, I am extremly happy of doing water rockets as a kid and knowing that from it
Thank you for the tutorial (This is a joke… maybe. But I’m nearly done my aerospace (astronautics focused) degree and have partaken in a fair bit of crackhead engineering myself)
This isn't going to have active aerodynamic surfaces is it? I know a lot of large hobby rockets don't because it changes it's classification and makes it much harder to legally launch. That's why so many are spin-stabilized. If it does have active pitch/yaw/roll control, that can put a lot of torsion on the whole airframe as well. It will be interesting to see the shrouds that cover the (non-keg) parts of the airframe.
Nice! Thank you! As I happen to be thinking about if this could strap on a xxl rc jet, ala shuttle, and woe there you flashed one... can one be strapped on and released at will?
I know we arent owed anything, but I am wondering why, when it was clear that the rocket was basically built since the first video, why it has taken half a year between 2 and 3 for this.
Clever rocket. But how many "episodes" are you going to tease us with on this project? The rocket was already built in the first episode a year ago. I'm not clicking on any more of these.
