新型电热结构防除冰性能研究
Investigation on Anti/De-icing Performance of an Innovative Electrothermal Structure
摘要
Abstract
Innovative development of an anti-and de-icing system which can be practically used for aircraft wings is an ongoing challenge.High energy-consumption of electrothermal anti-icing/de-icing in aircraft is a tough problem up to date.In this work,we design an anti/de-icing structure based on the electric heating.The electrothermal structure is composed of the polydimethylsiloxane(PDMS)insulation coating,conductive layer,electrothermal layer and porous insulation layer from the top to the bottom.The effect of the thickness of the conductive silver paste layer and the content of the conductive liquid on the temperature of the insulation layer and the insulation layer under different power levels is investigated.The results indicate that at room temperature,when the input power is 4 W and the thickness of the silver slurry layer is 300 μm,the maximum temperature of the insulation layer can reach 134℃.Moreover,when the input power is 18 W,the top temperature can quickly reach 0℃,while the bottom temperature remains around-12.5℃at-20℃,resulting in less energy loss.Our study can provide theoretical guidance for the design of electric heating anti-icing material systems.关键词
