High Altitude Simulation Chamber


The High Altitude Simulation (HAS) chamber recently acquired by CALCE is a one-of-a-kind piece of equipment. It is designed to replicate environmental extremes that an airplane may normally encounter during operation. From a hot, wet tropical environment at sea level to the cold, dry extremes 70,000 ft. into the upper atmosphere. The altitude test machine has the ability to simultaneously change temperature, pressure, and relative humidity.
