Calculation of Heat Required for WING THERMAL ICE PREVENTION in Specified Icing Conditions 480204
DATA exist now for the design of heated wings on a fundamental wet-air basis. The design method takes into consideration three factors:
Meteorological and flight conditions.
Area of water impingement, and rate and distribution of impingement.
Rate of evaporation.
All of the water intercepted by a wing which is to be heated only in the leading-edge region must be dispersed by evaporation. The design method provides for determining the heat required and the extent of heated area needed to evaporate the intercepted water.
