R.A.N. Sea King Cabin Environment Survey. Part 2. Measurement of Temperature and Humidity.
Abstract
Measurements of temperature and humidity have been made in a Royal Australian Navy Sea King over a period of four months. These measurements were carried out as part of a survey of the cabin environment which had been reported to be sufficiently adverse to cause impairment of crew efficiency, even when operating in moderate ambient temperatures. This survey has shown that the cabin temperature may be up to 12 C above the outside air temperature; this temperature differential, however, tends to decrease with increasing outside air temperature. Cabin wet bulb globe temperatures reached 32.3 C in an outside air temperature of 29 C. A WBGT level of 28 C is generally accepted as the level above which crew performance decreases; this level was reached at an outside air temperature of only 19 C. It is shown that operation of the Sea King to the extreme limits of outside environment such as the humid extremes of the Australian environment, or the United States MIL-STD-210B design environment (naval operations) would be quite impracticable, as it would be physiologically very hazardous to crew members.
