Silly thought, but one I had in the shower earlier today. Is there any way to simulate parallel staging in a cluster? Specifically, I'm thinking of a situation where you'd have several very large motors strapped together in a cluster, and then only certain sets (in symmetrical pairs) would be...

The other day, I was generously donated some spare 4" body tubes (and one coupler) for building an L1/L2 bird. However, I'm not entirely sure what they're made of, and because they're black, they don't photograph too well. Things I know: They're from Madcow Rocketry. They're 60" long and 4"...

I flubbed the title, and accidentally hit "post" while writing this. Oops. Title should be ""Naked" cluster drag simulations?" Just a simple question - is there any way to simulate a "naked" cluster? Basically, I'm thinking of a vehicle that has the motor tubes in a cluster open to the air...

Something I've been thinking about over the last couple days. As someone who is part of a university team myself, that had an upper stage ignition failure due to a faulty AV bay, this is a question that is near and dear to my heart. A lot of university teams, particularly those aiming to do a...

I want to clear up what I believe is my own misunderstanding. I'm very familiar with the concept of spin-stabilization, and my understanding of it revolves around giving the vehicle a very high spin rate in order to resist aberrations in thrust, aerodynamics, etc and average out forces during...

Hi everyone! Long-time lurker, first-time poster. I'm intentionally reposting this here and deleting the old thread, because on reflection it doesn't quite fit in "Rocketry Electronics and Software." No replies over there to miss, either. I'm exploring high-altitude darts, and conversations...

Hi everyone! Long-time lurker, first-time poster. I'm exploring high-altitude darts, and conversations with a friend of mine with a large amount of HPR experience has led to some design exchanges. Unfortunately, we both use different sim software - he uses RockSim, and I use OpenRocket. This...
