We just received the new nozzle for the shock tube from the 3D print house. We designed it but it needed laser lithographic instead of conventional printing so we had it printed by Shapeways. The shock tube runs at mach 2.2 now. The new nozzle will get it to Mach 3. After that we’re putting an expansion chamber on the end that will get it running at Mach 4.

Here’s the altitudes:
