Preliminary studies were performed, using both full-scale drop tests and one-third scale atmospheric wind tunnel data, to optimize a passive, high altitude, ram air, density sensor in terms of drag, stability, and fabrication. The drag coefficient of this evolved design was then evaluated by low density wind tunnel tests through the entire range of Mach and Reynolds numbers expected under full-scale operating conditions 0 M or 0.85, 500Re or 15,000. Limited additional tests were conducted to ascertain aerodynamic stability at these same conditions. An error analysis was performed on the wind tunnel drag data to establish the maximum error range for the experimental results. Author
