Do you have any tutorial videos for high school students that are starting the American Rocketry Challenge? I am looking for something that brings them through the very basics of design and simulation. Thanks, Jeff |

Hello Ali, We do not provide any certificates. OpenRocket is not an entity; we are simply a small team developing a free, open-source program in our spare time. Good luck with the competition!

My name is Ali Habibzadeh, a senior Mechanical Engineering student at Marmara University in Istanbul, Turkey. I have recently completed the following OpenRocket modules with great dedication: * Multi-selection and Multi-editing * Pods and Boosters * Export Design to OBJ File for 3D Printing I have practiced these topics extensively and consider myself highly proficient in each. Additionally, I am currently a member of an international student team participating in the International TEKNOFEST Competition, where we are using OpenRocket for various stages of our rocket design and simulation. Given my commitment and practical experience, I would like to kindly ask if it would be possible to receive a certificate from your team confirming my completion and proficiency in the above modules. Such a document would be extremely valuable to me in both academic and professional contexts. Thank you very much for your time and consideration. I look forward to your response.

Hello Wang, Thank you for the interest in OpenRocket. We have several documentation sources. You can find our user guide here: https://openrocket.readthedocs.io/en/latest/. We also have a series of tutorials: https://openrocket.info/tutorials/. You can also find plenty of OpenRocket tutorial videos online, for instance this channel has a good OpenRocket series: https://www.youtube.com/watch?v=nuLyZ4Es79A. For direct feedback, it's best to join our Discord server (https://openrocket.info/contact.html). You can not only get feedback from the OpenRocket developers there, but also a lot of other OpenRocket users that can provide valuable information.

Hi, My name is Uriel Rivera, and I am an undergraduate studying aerospace engineering. I am currently leading a few projects supported by the Royal Academy of Engineering to inspire primary and secondary school students to pursue careers in engineering. As part of this initiative, I plan to conduct a workshop that introduces high school students to CAD design and rocket building . I have previously used OpenRocket and found it to be the best tool for demonstrating complex engineering principals in model simulations. I would like your permission to use OpenRocket as part of my workshop. Also, if you're interested in the workshop itself, I would be more than happy to organise a formal meeting via Teams or Zoom to share more details and or discuss collaborations with your team. Thank you for creating a fantastic resource, I look forward to hearing from you soon. Kind regards, Uriel Rivera |
