Abstract
A fan of a gas turbine engine, which has a fan disk with a multiplicity of fastening elements which are spaced apart in a circumferential direction and which project axially forwardly from the fan disk, and a nose cone which is arranged upstream of the fan disk and which is connected by means of the fastening elements to the fan disk. On an axially front side of the fan disk, there is formed a periphery which runs in encircling fashion in the circumferential direction and which runs radially at the inside in relation to the axially rear end region of the nose cone, wherein the periphery which runs in encircling fashion in the circumferential direction forms a concave indentation, in such a way that water which ingresses into a gap between the axially rear edge of the nose cone and the fan disk passes into the concave indentation.
