You need a bit more than just a 3D printer to print metal parts. The general process involves printing your parts onto a build plate made of the same alloy, heat treating, then using an EDM to remove the parts from the plate. If any support material was used during the print it will need to be...

Thanks to your videos I am going to try and make my own system, bought a servo motor from hobby king (robostar sbrs-5314) that I am going to tinker with. Hopefully I can figure out how to mount a set on bearings and cram them inside of a 4"/4.5" tube. Would rather use dynamixel servos but there...

This is an older post but whatever. A control system like this can be simplified by making a few assumptions and initially ignoring canard angle. If the rocket has sufficiently low roll pitch and yaw then these three systems can be assumed to be independent of each other and tackled separately...

Our team number and school logo were painted on the fins, I doubt anyone will find it out there. They would have to walk within 20 feet of it to spot it. Using openFOAM in-compressible solvers it appeared that the fins were far enough back that they were not being affected by the payload bay...

Our rocket is at 32:30 in that video (Washington State University). It looks like it has two wind cocking events during launch, either that or we had stability issues; What do you think? I was standing at the cross road 90 degrees out from the video's point of view and it looked like it went...

from that video it looks like the failure occurred just above your CG from how the rocket moved during the explosion; was your CG on that destroyed area?

do you know what your decent rate was during main deployment on that first failure and where did the parachute fail exactly? Covert rocketry chutes are very similar to rocketman chutes right? That poor rocket lol; at least you got some good video from that last launch.

Your right, separation would depend on the forward section reaching a high enough velocity before the slot is uncovered to clear the rest of the coupling. The coupling section would also need to be well above the CG to create enough moment to kick the whole rocket over and the slot needs to be...

there must be a simple and effective way of kicking the rocket sideways during main deployment using a drogue system like this; I was thinking about seeing if I could cut a slot in the end of the coupling section so that main ejection gasses kick the rocket over to one side during separation. I...

I believe I can turn a custom motor retainer and have the tail cone attach to the motor retainer by gluing neodymium magnets into the motor retainer and gluing a small steel ring into a light weight aluminum tail cone. I can run two tubes next to the motor tube up above the forward bulkhead and...

Yes; I want to make a system that will release a tail cone which forms the apex of a drogue chute. The motor would remain attached to the body of the rocket. The drogue would not be deployed at apogee but during ascent to act as an air brake so that the rocket would be able to target an exact...

Does anyone have links to or know of any tail cone drogue deployment projects?
