DETERMINATION OF PARACHUTE DESCENT TIMES AND IMPACT LOCATIONS FOR HIGH ALTITUDE BALLOON PAYLOADS,

Abstract

Tables relating a wide range of payloads, terminal velocities, release altitudes, and descent times are presented for six flatcircular parachutes that measure from 12 to 100 ft in diameter. These data, together with a tabular method for forecasting drift trajectory and impact point, have proved to be accurate and convenient in expediting recovery of scientific payloads released from high-altitude balloons.
