Rocket bunny hardware kit, Oct 4, 2023 · Hello Rocketry Enthusiasts! I hope this post finds you all soaring high in your rocketry adventures! I'm a high school student currently navigating through the fascinating world of water rocketry for my research paper. Dec 31, 2025 · Hi, I'm a student trying to design a rocket made from scratch for the 2026 ARC competition, but I've run into some trouble when simulating on OpenRocket and getting the time predicted by the simulation to fall within the competition requirements (36-39s) while having a terminal velocity of 5 m/s May 29, 2023 · Hello everyone, I am currently in the process of building a HPR hybrid rocket motor and am posting to get opinions, advice, and help. My focus is on the optimization of water rocket fins in terms of their size Jul 3, 2025 · In my 50+ years of building and flying model rockets, I have only built one 2-stage rocket an Estes Hercules back around 1980. Propellant is paraffin wax with carbon black additive. See below, ignition at ejection charge to show delayed staging The motors above the H100/I357 are in the stock example sim, I'm ignoring those for now These are set to automatic, ignition at ejection charge Now switched to first burnout This is the stock 2-stage example rocket Jan 12, 2026 · Hello everyone, We’re designing a high-altitude student rocket with a transonic/low-supersonic flight profile, and we’d really appreciate feedback on our material choices and structural approach. To post you must either be a member for 30 days AND have 20 posts OR be a Supporting Member. We’re currently debating between using movable fins (canards) or thrust vector control (TVC) Feb 14, 2025 · So I took the 'stock' two-stage rocket in OpenRocket and tried a few different delays on the booster motor. Our goal is a build that’s safe, repeatable, and structurally robust under high dynamic pressure Dec 2, 2021 · Hello everyone, I would like to introduce you to a gyroscopic stabilization system which I made. It was right at 25 years later when I finally got around to flying it, and on the first 2-stage flight the booster section got stuck on the sustainer after burn-out (the spent motor dropped free) and got totally If you have a personal rocketry-related item for sale, or that you're looking for, this is where you list it. These are for one time sales items, no business sales. Electronics: flight computers and or altimeters to help with dual. deploy, cable cutters, recording the flight parameters, tracking devices to help find the project. The system is designed to prevent the rocket from rolling. The idea is to use it with rockets that have a built-in camera or other equipment that does not withstand the rolling of the rocket during Apr 23, 2021 · The advanced rocket will be multi stage rocket projects but has a new set of flight challenges. The motor has a theoretical average thrust of 800N 2. Oxidizer is N2O I have already Oct 4, 2023 · Hello Rocketry Enthusiasts! I hope this post finds you all soaring high in your rocketry adventures! I'm a high school student currently navigating through the fascinating world of water rocketry for my research paper. 3. Oxidizer is N2O I have already. Oct 6, 2024 · Question Hi everyone! 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.
