New hybrid storage solutions

We've been beavering away on the Rocketry Experimental High Altitude Barosimulator (REHAB) element of our Low Orbit Helium Assisted Navigator (LOHAN) mission, and last week enjoyed a lightbulb moment as to how to create a decent seal between the metal hypobaric chamber and the glass lid.

This is the final concept, reached after a not inconsiderable amount of head-scratching, and plenty invaluable input from our beloved reader experts...

Here's a quick recap on how we put the chamber together. First up, our CAD-modelling expert, Federico Buenadicha, put together a representation of the REHAB chamber and inner assembly:

The CAD plans were whisked off to the plasma cutting machine, which crafted the essential inner assembly parts and flange:

Down at the local metalworks, Antonio Parra Cifre put the whole thing together...

...and in a couple of hours we had the finished product. Note the addition of a flat metal plate to the chamber's outer wall, to allow connection of the evacuation tube, thermocouple and ignitor wires:

Our test motor - an AeroTech RC 32/60-100NS - will sit inside the chamber like this, with a ring-type thermocouple strapped it its meaty girth:
