Hello out there!
I'm an Aero. Eng. Undergrad testing a reusable carbon fiber motor casing designed around a CTI Pro 75-4G 5015L1115-P reload. My team and I intend to use the propellant grains and spacer O-rings but, we will provide our own insulation and Nozzle. My question is: Does anyone out there happen to know the dimensions of the grain spacer O-rings Cesaroni uses in their Pro 75 reloads? ... specifically their width? I need to know this so that I can figure out exactly how long the case needs to be. At present, this is the only dimension totally unaccounted for. Although, if anyone could confirm the length of the grains themselves, that would also be extremely helpful. I currently have information that they are 5 5/32" long...
The forum has been extremely helpful to me in the past but this is my first time posting anything. I really appreciate any help anyone can provide. Thanks!
