help needed

I have created a model rocket design capable of 2500 ~ 2700 ft, and I am wondering if my model rocket design is missing something. I have: 1. The two engines for the individual stages. 2. The engine blocks. 3. Tube couplers for my staging. 4. Parachute and shock cord. 5. Mass component of 70...

I'm not sure if the file uploaded correctly, but, when I run flight simulations, Open Rocket says I'm accelerating at 2584 m/s^2. I don't think this is normal and I'm wondering how I can fix this. Thanks.

Good day, with my local club launch in a week, I need to get this case ready ; the aft closure has seized terribly and nothing I have tried so far has been successful. So far I have tried, WD40, lubricant, hot water, knocking it against a hard surface, rubber grips, water pump pliers, and all...

Does anyone know what the fin specs of LOC Precision's 3.1" Hawk Kit are? The kit is discontinued and I'm trying to DIY it...if anyone knows the length and measurements of this specific kits fins that would be great to know for my project. Thanks

Hello, My bamachutes order was cancelled and I have got an email that I will get refund on credit card in 5-10 days, but there is a problem - I do not have that credit card and access to the bank account. I wanted to contact with BAMA, but their site and everything is down. The money I've paid...

Hello everybody I belong to a group of students currently undergoing our studies in Mechanical Engineering, Civil Engineering and Electrical Engineering at the University of Costa Rica. We have been involved with Aerospace activities as active members of the Aerospace Engineering Group (GIA)...

Hello! I’m currently doing a project for my Science class. Basically, we have to design a rocket from water bottles and try to make it have the most airtime. This includes from the time it launches to when it falls on the ground, parachute deployed and all. I’ve done a lot of research but...

Hey guys, this is my first post here and my first excursion into model rocketry, so if you have any resources you think would help me out, let me know! I've wanted to build a small-sized rocket since a few summers ago, but only now am I actually considering going through with the task in a...

Hey everyone, Being an IB student requires one to write a 4000 word essay on a subject of your preference. Mine is physics. So, I wisely decided to conduct an experiment based on model rocketry; namely potassium nitrate and sugar rockets, but dry compacted like Grant Thompson does it in the...
