SUMMARY:

This study examines the aerodynamic effectiveness on the iced rotor blades in hovering flight, with particular attention to the influence of the number of iced blade sections. A computational fluid dynamics (CFD) framework is employed to model ice shapes using a loosely coupled methodology that integrates aerodynamic solver, droplet impingement solver, and ice accretion solver. Two-dimensional ice profiles are generated at selected blade sections and subsequently interpolated to construct a three-dimensional iced-blade configuration. Local inflow conditions for each section, including the induced velocities and angles of attack, are determined using blade element and momentum theories.
The results indicate that the resultant aerodynamic forces and moments of the three-dimensional iced rotor blades are highly sensitive to the number of blade sections. These findings emphasize the importance of selecting the appropriate numer of blade sections when analyzing the aerodynamic degradation under icing conditions.
