What are the design considerations for a LPR motor mount? What determines the length of the tube and placement of centering rings? I notice in kits the tube usually extends well past the thrust ring. Any reason for that? (I'm not talking about stuffer tubes, just an extra long motor tube.) Would...

Hello all, Has anyone used a Xoss GPS tracker? I've received mine and looking for a 3D-printed mount and thought maybe someone has already made one for it. Ralph

Hello everybody. I've got a rocket I am working on with an aspect ratio of about 22.5 (length to diameter). At this point, I am not concerned, but I was wondering at what point I would start to encounter issues or have to take other considerations into account if I were to increase the length...

Is there any formulas for wing area vs rocket length? I what to build a customer rocket. I know I have to have the center of gravity higher than the center of pressure. If the fins are too small, not enough pressure (CP too high), weight distribution wrong, then may need to put clay in cone. I'm...

I need to draw a nose cone using solidworks but I couldn't draw, can you help? power series ,parabolic series or haack series. I need one of these three. please help me

I picked up a couple of parts from a free parts bin at my local launch, and want to build a ring tail rocket with them. My current plan has a 4 inch body tube and a 5 inch ring tail that is 1 inch long. However, I am dubious of RockSim's accuracy on the matter. Adding a ring tail to the rocket...

Hello! This is a thread where I'll be posting my designs for rockets, some which may eventually get built. Please feel free to make any sort of comments on my designs, i would appreciate the input. Also, this thread is inspired by neil_w's half-baked design thread

I am a total beginner to designing models, though I've built ones which are readily available online. Therefore, if someone here could point me in the right direction as to how I can start designing rockets and spacecraft for making card models, I'd be very grateful. I have no idea on how to...

Hi, Today I would like to share with you my first ever rocket: Cormoran MK1 Specs: Length: 370mm Body diameter: 32mm Propulsion: C6-3 Mass with motors:124g Expected apogee: 150m (~495ft) Build material: PLA About it: I have been interested in rocketry for a long time. For one reason or...

I've been designing a simple one stage rocket with OpenRocket, which allows the user to design and simulate their designs. I was always told that a general rule of thumb for a rockets stability is that the center of gravity should be 1-2 calibers above the center of pressure. With this rule...

I am hosting a 3D design and printing contest. I would like to see the product utilized and not just a concept. What should the rules be? Rules: It must be your design and not off thingverse etc. Not just a concept. Show utilization or flight. Post an image with the part, rocket, jig being...
