LETTER PROGRESS REPORT FOR APRIL 1962 ON HIGH ALTITUDE SAMPLING
Technical Report
·
OSTI ID:4805137
Progress is reported in the design and testing of equipment for high- altitude air sampling. The operational characteristics of an air ejector were tested over a complete range of back pressures and primary pressures. Data are tabulated. Modifications were made in an altitude sensor for use on balloons at high altitudes. A balloon flight was made to 110,000 ft with two direct-flow units and an electrostatic precipitator. A sketch is included of the flight train and components used. Total payload on the balloon was 506 lbs. A second balloon flight was made to obtain a vertical profile of radioactive debris with directflow units at 70,000 and 80,000 ft. This was accomplished by using a gondola equipped with two direct-flow units and ballast to float the system at the lower of the two altitudes. After sampling was completed at the lower step, the ballast was dropped, and the system ascended. Total payload on the balloon was 865.5 lb. (C.H.)
