Material for Chimera B0
Chimera is in the process of selecting the material, and supplier, for the main motor tube. The type of aluminium alloy, as well as its wall thickness is important. The tube must withstand great pressure. The problem is complex, for ideally we would like to make a 38mm motor, to fit standard motor tubes and retainers. If the walls are, say, 2mm thick, then the inside diameter is 34mm. The problem is, such a size is very rare, or impossible, to find for the plastic rod for reload/fuel.
