N1 disc AI capability
Recently had an icing encounter that had me wondering about engine blade icing. Rime icing on the N1 blades caused high VIB's on both engines and airframe buffeting. Cowl AI was on, but that's not not going to stop the blades from icing up. Do any engine manufacturers past or present have anti icing capability for the N1 disc? Seems to me heating them by some means would rob the engine of further by robbing more bleed and potentially raising the air temp.
