Airplane Window Bleed Hole Simulator

OUTSIDE ATMOSPHERE INTER-PANE CAVITY PASSENGER CABIN

Cruising Altitude 35,000 ft (10,668 m)

Nominal Cruise Physics: The bleed hole in the middle pane lets cabin air gently pressurize the inter-pane cavity to 11.80 PSI. This routes 100% of the cabin pressure differential (8.34 PSI) onto the thick outer acrylic structural pane, keeping the middle pane stress-free while venting moisture to prevent window fog and frost.
