“…The evaluation of the anti-icing system of engine components is usually conducted in the icing wind tunnel, considering its lower cost in comparison with the engine icing test cell. A number of experiments were carried out to investigate the physical aspects of ice accretion on the aircraft wing or the engine inlet [21][22][23][24][25][26][27][28][29]. On the other hand, some research experiments are performed to study the ice protection systems.…”

Icing and anti-icing characteristics of engine inlet guide vanes are studied in this paper. Experiments are carried out in an icing wind tunnel under different icing conditions. The tests are performed at a freestream velocity of 85 m∕s, an inlet angle of attack of 0 deg, and a freestream static temperature in the range of −8 ∼ −20°C. The icing environment parameters include a mean volume diameter of 20 μm, liquid water content in the range of 0.5 to 2.0 g∕m 3 . The experiment is performed on full-scale inlet guide vanes. The temperature distributions on the guide vane surface are measured by thermocouples. The leading-edge ice shapes of inlet guide vanes are compared under different icing conditions. The effects of freestream static temperature, liquid water content, and the mass flow rate of anti-icing hot air on the performance of the anti-icing system are presented and analyzed.
