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. My focus is on the optimization of water rocket fins in terms of their size...
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. We’re currently debating between using movable fins (canards) or thrust vector control (TVC)...
Long story short I just got my Level 1 over the weekend and flew it low and slow. But now I might like to reach for the stars as it were lol. I'm terrified of losing my rocket though and am contemplating investing in some sort of tracking system. I know these "egg timers" are suggested but yes...
FWIW here is 369 pages of design/construction info on the Mojave Sphinx, apparently very similar to the Half-Cat rocket. 350 lb thrust for five seconds. A two-minute YouTube video.
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. 3. Oxidizer is N2O I have already...
The advanced rocket will be multi stage rocket projects but has a new set of flight challenges. Electronics: flight computers and or altimeters to help with dual.deploy, cable cutters, recording the flight parameters, tracking devices to help find the project.
These either requiere the rocket to have a certainly speed to work or a heavy supporting structure to enable the deployments. If the objective is to minimize weight and for the deployment to occur as far and as close at apogee as possible, wouldn't this Rocket Extraction method be very practical? I would love to know your opinion. Thank you!
Hello everyone, I would like to introduce you to a gyroscopic stabilization system which I made.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...
Looking at your rocket, I'm thinking you need a bigger rocket, and probably a few more years of experience flying high power rockets. Even with the biggest LOKI motor, the M1378, you would still come up short by a few hundred feet. That motor is almost 4 ft. long. Your design would not be long enough to hold that motor, and would probably not ...
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. I am trying to answer the age-old question is if this rocket is over-stable. The only “rule of...
