Abstract

Abstract: Aircraft ground freezing could lead to potential danger and delay for flight. To alleviate these problems, the main method is to use the deicing fluids to clean ice or snow on the aircraft body, which lacks of reference of the deicing fluids parameters and efficiency. To study the effect of the deicing fluids parameters on the aircraft deicing efficiency, the deicing mechanism is analyzed.The black box mathematical model of the deicing process is generalized abstractly. The deicing process is divided into two subprocesses to establish the deicing model.The relevance between the deicing fluids parameters and deicing efficiency is studied through numerical simulation method. Experiments show that the deicing efficiency is positively related to the deicing fluids temperature. But the deicing velocity could not be enhanced with a big fluids flux in a moment, yet more deicing fluids are wasted massively. Experimental results verify that the deicing mechanism is reasonable, which provides a basis for deicing equipment qualification and performance optimization.
