Abstract: A gas turbine engine fan blade (22) and disk assembly (30) is provided with levers (36) with which to apply a force to the radially inner end of respective blades (22) so as to move the roots (26) of the blades (22) into abutting engagement with the side walls of the inverted “V” shaped grooves (32) in the disk rim (34), and thereby prevent relative wearing movement therebetween. The levers (36) are appropriately moved by rotation of respective screws (52) that pass through exposed ends thereof in screw threaded engagement, and abut a fixed land (46) so as to apply a pivoting force on each lever (36).

Abstract: A gas turbine engine nose cone (44) comprises a spinner (46) and a fairing (48). The spinner (46) has a conical upstream portion (50) and a cylindrical base portion (52). The fairing (48) is frustoconical and surrounds the base portion (52) of the spinner (46). The outer surface (68) of the fairing (48) forms a continuation of the outer surface (56) of the conical upstream portion (50) of the spinner (46). A fibrous material (86) extends around the upstream end (82) of the fairing (48). The outer surface (68) of the fairing (48) has a skin (80) to protect the fairing (48) from erosion. The skin (80) extends around the upstream end (82) of the fairing (48) and is infiltrated into the fibrous material (86) to form a composite material and to bond the skin (80) to the upstream end (82) of the fairing (48).
