A fan blade anti-icing system comprises a fan hub (12) and a fan blade (1) extending radially outwardly from the fan hub (12). The fan blade (1) has a base (14) and an airfoil (15) extending radially outwardly from the fan base (14). The airfoil (15) having a leading edge (17), a trailing edge (18), a convex side surface (19) between the leading and trailing edge (17, 18) and a concave side surface (20) between the leading and trailing edge (17,18). The fan blade (1) further has a radial passage (21) extending from a blade air inlet (22) in the blade base (14) in communication with a source of heated air, and a rearwardly directed passage (23) in communication with the radial passage (21) and having a blade air outlet (24) forward of the trailing edge (18) and oriented tangentially to the convex side surface (19) or concave side surface (20) of the airfoil (15).
