RESULTS OF TEST PROGRAM ON AIRCRAFT DEW POINT HYGROMETER.
Abstract
An aircraft dew-point hygrometer was evaluated to determine the operating limits of dew point, altitude, Mach number, ambient air temperature, response time, and repeatability. The unit was evaluated under the environmental conditions of MIL-E-5272E and flight tests were simulated in a humidity atmospheric chamber. The test results indicated that the test system is best suited for low altitude sampling from aircraft flying at low Mach numbers. System improvements needed to extend this altitude and Mach number were determined. The improved system should be limiteed to minimum dew points of -60F to avoid the increased response time occurring as dew point temperatures are decreased. (Author)
