The High Altitude Turbine Survey (HATS) is an attitudinal wind velocity experiment aimed at understanding thrust and other performance characteristics of micro-propellers along a vertical profile (35km).  The survey data will have a wide range of application towards further study including wind power generation from airborne turbines, propeller-driven airships, and micro-propeller performance characteristics at extended altitudes.
