🚄 Low-Pressure Tube Pod Lab: Kantrowitz Limit, Drag and Tube Pressure

Pod in a low-pressure tube: compressible flow in the gap, the Kantrowitz limit, drag power versus speed and tube pressure, an onboard compressor option, curve g-loads and pump-down energy. A Blender-built, Three.js teaching model.

⚙ Under the hood

A pod in a partial-vacuum tube, inspired by the publicly published 2013 'Hyperloop alpha' concept: quasi-1D compressible flow in the annular gap, the Kantrowitz choking limit versus blockage ratio, the air column that builds ahead of a choked pod, an onboard-compressor option, drag power versus speed and tube pressure, curve g-loads and pump-down energy. Existing maglev sims do not cover tube aerodynamics. Blender-built pod and tube cutaway with a density/Schlieren slice.
