Electro-thermal Anti-icing Characteristics of Composite Strut of Aeroengine Inlet
Composite part is of low quality and high intensity, and composite is a kind of material preferred for aeroengine inlet part now. Under icing conditions, the inlet of aeroengine is prone to icing. Icing in inlet of aeroengine causes degradation of performance and menaces the safety of the aeroengine, so the composite inlet must be protected from icing. Electric ice protection is the way forward and is one of key technologies for composite part. The 3D Reynolds averaged Navier-Stokes equations and 冋 儃 k model are used to simulate the airflow over the strut in aeroengine composite inlet. A Eulerian model for airflow containing water droplet is used to get the water droplet trajectories. The supercooled water impingement on the strut surface is achieved based on a certain flight icing condition, and anti-icing heat-load and overflow-water distribution on its surface is also obtained on both complete evaporation and incomplete evaporation. On the basis of the results, the configuration and heater mats for composite strut was designed. The experiment for electro-thermal anti-icing characteristics was made on certain icing condition, and anti-icing effect was got on different electro-thermal conditions. A comparision between calculation and experiment results was made, and the two fitted each other well.
