This is being worked on by Pat G.
He's got the casing dimensions and before too long should have some good working numbers.
It's going to be cool to see what he comes up with!
Sorry guys, been a tad busy, plus I have been waiting to see what diverges over the rocket design and dry weight. I have Dude Perfect coming out to the ranch next week to shoot a video, so I am busy doing prep work for that (and yes, I heard it was going to be about rockets, so check em out on YouTube).
The neat thing about designing your own power plant is that you can design it "around" your project, NOT the other way around.
For instance. Have a big heavy slug for a rocket? Build the motor to BAM on the ground to get it moving, and then taper off to sustaining thrust.
Want a realistic, slow takeoff of a project? No problemo, design a flat burn 4.5 to 1 thrust to weight ratio.
Whatever we decide we want, I have the equipment to do a full motor test giving me thrust, MEOP/operating pressure, time, even exhaust heat and hardware external heat temps from bulkhead to nozzle.
I assisted TMT for years certifying mfg motors for commercial release, and I can assure you no mfg of commercial hobby motors at that time, or now to my knowledge, had any testing beyond thrust and time.
(Notice Anthony and Gary, I said "hobby" motors....
Gonna be fun. When we do a full up motor test before we commit it to project flight, we'll post it on youtube and provide you folks the link.
