Research on Anti-icing Design and Thermal Load Calculation of Civil Aircraft-Water Supply Pipeline
The water supply pipelines on civil aircraft are almost located at the bottom of the equipment cabin without temperature control,and almost run through the entire aircraft.In low-temperature environments,icing is likely to oc-cur.In this paper,an anti-icing design method for civil aircraft water pipelines is proposed,based on the energy conser-vation and the theory of multi-layer circular tube heat transfer.The required parameters are reasonably assumed,and the anti-icing design for water pipeline is attempted.In order to verify the method,the numerical simulation methods is adopted,too.The results indicate that it is necessary to carry out anti-icing design for aircraft water supply pipe-lines,and the method proposed can meet its anti-icing design requirements,providing theoretical basis and data sup-port for the anti-icing design.
