Hi, i'm curious is there a recommended ratio of rocket length to diameter for the most efficient design? I’m currently operating off a chromebook right now and i was wondering if there were any free alternatives to open rocket that could be run on the web or downloadable on chrome os I don’t care much about the design part of openrocket but finding the center of pressure is the most important. I first designed this rocket on openrocket, where i saw a peak altitude of 11453ft and a maximum speed of 315m/s. I have the attached rocket modelled in openrocket where the nose cone, payload section, and recovery section are existing sections and have specific overridden mass and cg values that are actuals I am removing the previous fin can section and replacing it with a fin can assembly consisting of.
What are your favorite model rockets made by estes? So i'm currently in the process of designing a ssdd 4 goblin rocket in openrocket that i later want to upgrade to be a cluster rocket For my previous rockets, i've kept my stability between 1 and 1.75, but my friend was telling me that i should be looking at a lower stability for a low length. I'm building my first mid power rocket and going with the balsa machining 3 29mm school rocket I have the kit and have modeled in open rocket using exact measurements and having weighed each part With a stock build, and adding 50 grams of clay nose weight, i'm getting a ground hit velocity.
