Abstract:
A fan hub assembly for a gas turbine engine includes a fan hub that is configured to rotate about an axis. The fan hub has an axially extending aperture and a platform. A fastener is received in the aperture in a slip fit relationship to secure the platform to the fan hub.
Abstract:
A method for balancing a rotatable component is disclosed This method comprises and then plating the component to deposit a metal layer onto the component until the component is balanced. In addition, and alternative method for balancing a rotatable component is disclosed. This method comprises attaching a balancing weight to the rotatable component and rotating the component. This is followed by plating the component and the balancing weight to deposit a metal layer onto the balancing weight and the component until the component is balanced.
Abstract:
A duct (78) has: a first non-metallic member (86) extending between a first end and a second end, at least at the first end having an outwardly-projecting flange portion (94); a metallic flange member (90) having a sleeve (180) extending between a first end and a second end and a flange (140) extending outward from the sleeve and having a first face (144) and a second face (142); and a second non-metallic member (88) extending between a first end and a second end having an outwardly-projecting flange (150) portion, the first non-metallic member flange portion mounted to the flange first face and the second non-metallic member flange portion mounted to the flange second face.
Abstract:
A fan rotor includes a fan hub and a plurality of fan blades extending radially outwardly from the fan hub. Platforms (106) are positioned intermediate blade sides (122) of adjacent ones of the fan blades (102). Seals (124) are positioned between the blade sides (122) and platform sides (120) of the platforms (106). The seals (124) have an elongated attachment portion (126) bonded to one of the platform sides (120) and the blade sides (122). The seal (124) extends radially outwardly from the elongated attachment portion (126) to a wedge portion (134).
Abstract:
A nose cone may have a spinner including a main portion and an axially extending stepped portion. The nose cone may also have an annular aft support ring radially secured to the axially extending stepped portion. The nose cone may further include a fairing, which may be secured to the stepped portion.

Abstract:
A spinner (80) for a gas turbine engine (20) comprises an outer shell (82) for defining an airflow path when mounted in a gas turbine engine (20). An inner surface (84) is provided with a plurality of webs (86). A gas turbine engine (20) and a fan section (22) for a gas turbine engine (20) are also disclosed.
Abstract:
A gas turbine engine (20) is provided. The gas turbine engine comprising: a fan section (22) having a fan; and a containment zone (100) encircling the fan, the containment zone comprising: a ballistic liner (200; 300; 400) composed of a plurality of ring segments (220a-e; 320a-f) located radially outward of the fan; wherein each of the plurality of ring segments include two opposing circumferential ends (230a, 230b; 330a, 330b), and wherein the plurality of ring segments are arranged circumferentially around the fan section and the circumferential ends of each of the plurality of ring segments meet at joints (240; 330) to form the ballistic liner.
