DEVELOPMENT OF AN EXPERIMENTAL AIRCRAFT HYGROMETER.

Abstract

Two experimental aircraft hygrometers using dry-ice heat sinks were designed and constructed, both units recorded frost points below -80C when flight tested at altitudes to 65,000 feet aboard a U-2 aircraft. A third hygrometer which requires no chemical heat sink was also designed, built and laboratory tested. In addition, a heat-transfer analysis was conducted to allow predictions of the instrument's capability as a function of altitude, free-air temperature and Mach number. This report describes the instruments and presents analytical and experimental results of the program. (Author)
