Research On Electro-thermal Performance Of Carbon Nano-paper Composite Wing Structure

In view of the present problems and phenomenon in the process of aircraft electro-thermal anti-icing, this topic explore the electro-thermal performance of carbon nano-paper composite wing structure. Through the combination of simulation and experiment method, design of carbon nano-paper electro-thermal layer, temperature distribution between the carbon nano-paper composite laminate, heat transfer performance of carbon nano-paper composite wing structure are studied. This paper provide the reference for the heat flux density selection of the carbon nano-paper composite wing structure under the anti-icing conditions, so as to save energy, improve the efficiency of experiments.Firstly, material selection, shape design, current density simulation and thermal imaging testing are analyzed to prepare carbon nano-paper electro-thermal layer.Secondly, using the vacuum bag molding process to make the carbon nano-paper composite laminate, and test the temperature distributions of carbon nano-paper composite laminate and carbon nano-paper composite wing structure under different environmental temperature and heat flux. The temperature distribution between the carbon nan-paper composite laminate layers in different environmental temperature and heat flux conditions is simulated, the solution is compared with thermal imaging experiment. Then, heat transfer simulation is used for carbon nano-paper composite wing under the different heating modes to obtain the corresponding relation between the environment temperature, heat flux density, wind speed and composite wing surface temperature. Finally, verification experiment of carbon nanao-paper composite wing structure is compared with the simulation results of the surface temperature, verify the reasonableness of carbon nano-paper composite wing structure model, provide guidance for the icing tuunel experiment of nano-paper composite structure in the future.
