"Ice formations penetrated to the second-stage rotor blades"
"Preliminary Results of Natural Icing of an Axial-Flow Turbojet Engine" 1
Abstract
A flight investigation is being conducted. in natural icing con- ditions to determine the effect of ice formations on the perforxnce of en axial-flow turbojet engine. One flight was made in icing con- ditions in which the icing rate varied from 5.1 to 2.1 inches per hour. During a period of 45 minutes in icing, the tail-pipe temperature increased from 761° to 1065° F and the jet thrust decreased from 1234 to 910 pounds. Ice penetrated to the second-stage stator blades. No general conclusions can be reached from these data because the icing condition was relatively light.
