I've really been wanting to build a large 2-Stage project for a while. Every few years or so I try to build something large and extreme, though this time it has been 8 years. The last one was the Proton M Group Project with NCR in Colorado, a 3-stage, 18 motor mount beast with a stunning array of electronics. It was an amazing and incredibly challenging project. Not totally successful, but safe and mostly recovered intact and rebuildable .. always a good thing on extreme projects.
For this one I've scaled the complexity back and gone with a straightforward 2-stage approach. It'll be 10" diameter, 14' tall, 4 fins design. I'll have a 4" MMT in the Booster with a 3" in the Sustainer. I'm debating adding some 38mm MMTs around the 3" for effect, we'll see. I'll use 10" sonatube for the body, 1/2 ply for the fins, styrofoam for the nosecone, all fiberglassed. Final weight will of course determine final motors, though trying to keep it light. It will be low and slow for the most part, but quick enough off the pad to be very stable. Definitely no mach speed issues. Should be another fun one! Here's a rough design:
Here's a shot of the Proton M from 2012 with some of the amazing team from Northern Colorado Rocketry!
