一般注記In this paper, analytical study concerning the freezing and sticking phenomena of slush on the horizontal tail surfaces of a twin turboprop transport in the ground taxing and the succeeding take-off run phase is conducted. A simple mathematical model describing the outflow of heat from slush to the surrounding airflow through the boundary layer is proposed. Both the conductive heat transfer and the heat transportation accompanied by the evaporation of water from slush are taken into account. The influences upon the heat transfer rate caused by climatic and operational conditions, such as the atomospheric temperature, the dew point, the ground speed, the suction coefficient over the horizontal tail surfaces, the propeller slip stream effects and the roughened surface covered by the slush are quantitatively evaluated. Under the illustrative climatic conditions occasionally experienced by airline operations in winter season, the outflow of heat large enough to stick the elevators is predicted, during the 5 minutes ground operation after starting the engines and the following 25 second take-off run. During the course of analysis, the condition which cause, and the factors which accelerate, the freezing of slush are defined.
