Rocketry forums for experts & beginners Engines, recovery, electronics, rocketry software. We’re a university team just getting started with building model rockets, and one of our main goals is to develop an active control system We’re currently debating between using movable fins (canards) or thrust vector control (tvc). I have a tall/thin rocket with a fineness (aka aspect ratio or length to diameter ratio) of ~26 (80” long 3.1” diameter) As currently configured, it has a stability margin of 3.7/14.6% in openrocket
When the rocket is completed, everything is installed, except the motor, then weight it, and determine the cg Use those to override mass and cg in or Once you do that, you should get much better sims from or Have you considered what motors you want to fly after you have gotten the l1 cert Or is this rocket going to be a one flight and done? These either requiere the rocket to have a certainly speed to work or a heavy supporting structure to enable the deployments
I would love to know your opinion Hi, k'tesh here.i volunteered to help create an openrocket tutorial for nar's sports rocketry magazine, but due to issues with time and trying to find the right subject, i missed my shot But i did create the tutorial Rather than let it go to waste, i've decided to post it here I first designed this rocket on openrocket, where i saw a peak altitude of 11453ft and a maximum speed of 315m/s. Hello everyone, i am currently in the process of building a hpr hybrid rocket motor and am posting to get opinions, advice, and help
The motor has a theoretical average thrust of 800n 2 Propellant is paraffin wax with carbon black additive Oxidizer is n2o i have already. I downloaded the zephyr rocksim file from apogee I first noticed that i couldnt do a mass over ride for the nose cone when i added the j270 as my motor I want to add some mass since the caliber is below 1, and i like to have it about 1ish
