摘要
Abstract
Based on the ground icing-test data of a certain type of helicopter tail rotor, an analytical model of iced rotor aerodynamic performance was established. It was found that the lift and drag coefficients of NACA0012 blade section airfoil by the model correlated well with test data. Based on the established model, the characteristics of tail rotor blade airfoil was calculated both for clear and iced situations by Fluent code The results showed that icing reduced the lift coefficient and increased the drag coefficient of blade airfoil. At last, a method to analyzing aerodynamic characteristics of tail rotor on icing condition was formulated by using element -momentum theory in combination. The final results showed that icing could reduce the thrust coefficient and increase the torque coefficient, which significantly deteriorated the aerodynamic performance of the tail rotor.关键词
