Environmental Tests of Meteorological Radiosondes Including Dynamic Temperature and Humidity Simulation in a Wind Tunnel
Abstract
An experimental investigation of the performance of meteorological radiosondes subjected to controlled variations of humidity and temperature in an environmental wind tunnel is described. Dynamic variations in temperature between -60 and 40C and in relative humidity between 0 and 100 percent, representative of those encountered in atmospheric flight were simulated by injecting liquid nitrogen or steam, respectively, into the wind-tunnel air supply. Tests were conducted at free-stream velocities of 15 and 75 ft/sec duplicating the average ascent and descent rates, respectively, of balloon-borne rawinsondes and dropsondes. Free-stream static pressures appropriate to the 300- and 700-mb levels were employed.
