In order to understand the icing law on the inlet strut of an aero-engine and the anti-icing law of the inlet strut with the hot-gas,the anti-icing experiment, ice melting experiment and the icing experiment were carried out on the inlet strut in the icing wind tunnel.The results indicate that the heat flow of the inlet strut increases with increasing entrance velocity but decreases with increasing entrance temperature. Ice mostly appears on the leading edge of the strut and the thickest ice appears close to the stagnation location.The glaze ice occurs easily when the initial temperature of the strut is relatively high and drops slowly.The rime ice occurs easily when the entrance temperature is relatively high and the temperature of the surface drops precipitately.Besides,the results provide a basis for the design calculation of the inlet strut and some references for aero-engine anti-icing system design.
