The paper presents the wing airfoil rime ice accretion prediction code R-ICE 1.1. The rime ice accretion model includes the calculation of a velocity distribution round a wing airfoil. The resulting flow field is used to an aerodynamic forces acting on water droplets determination. The set of differential equations describing particle trajectories through the local flow field is derived from the spherical shape droplet motion equations. Results of the droplets trajectories solution are used for the determination of a water mass flux impacting on the wing airfoil surface. There are presented some computational results of the volume median diameter droplets influence on the airfoil droplet collection efficiency. The impacting rime ice accretion changing the airfoil shape is illustrated in compare of experimental results.
