Abstract : The Open Skies FOC surveillance aircraft's (WC-135B) thermal environment is constantly changing per mission profile. Supplementary heating and cooling equipment is required on board the aircraft to maintain environmentally controlled temperatures for the preparation and storage of exposed and unexposed film. Temperature chambers located within the Transparency and Thermal Systems Laboratory (TATLAB) were used to demonstrate the thermal performance of electrically powered Narcold TEK-II coolers and a similar-sized heater in meeting the open skies POC cooling, heating, and storage requirements. The coolers and heater, instrumented for temperature measurement and thermostat-regulated operation, were examined over the expected operational range and WC-135B environmental conditions. This report documents the findings of the Transparency and Thermal Systems Laboratory in-house tests and offers installation/design recommendations. In addition, the experimental results have been recorded herein as comprehensive tables useful to open skies personnel in predicting film temperatures based upon mission conditions.
