Inlet cone of a jet engine

Inlet cone (1) designed as a turbofan jet engine (10) having an engine core region (11) and this sheath region surrounding (12), wherein the inlet cone (1) is arranged concentrically in the air inlet area of ​​the jet engine (10) and rotatably mounted on a mounted shaft (14) is arranged, wherein the inlet cone (1) has a cone angle (15), in which with the air flow to the inlet cone (1) impinging solid body (16) in the movement paths (17) to bounce from this that (the solid lead 16) predominantly (in the cladding region 12). For an inlet cone (1) is provided in which the entry of solid bodies 16 in the engine core region (11) is minimized.
