    • A fan casing arrangement for a gas turbine engine and related method.
      A fan casing arrangement for a gas turbine engine (10) of a type having a propulsive fan (12), the fan casing arrangement having a fan case (24) and a fan track liner, wherein the fan track liner is provided around the inside of fan case (24). The fan track liner includes an elongate member (25) which is helically-wound against the inside of the fan case (24) in a plurality of turns (27). There is also proposed a method of installing a fan track liner in a fan casing arrangement for a gas turbine engine (10) of a type having a propulsive fan (12), the method involving: providing a fan case (24), providing a flexible and elongate liner member (25), and helically winding the liner member (25) against the inside of the fan case (24) in a plurality of turns (27) to define at least part of the fan track liner.
    • 一种用于燃气涡轮发动机的风扇壳体装置及相关方法。 一种用于具有推进风扇(12)类型的燃气涡轮发动机(10)的风扇壳体装置,所述风扇壳体装置具有风扇壳体(24)和风扇轨道衬套,其中所述风扇轨道衬套围绕所述内部 的风扇箱(24)。 风扇履带衬板包括细长构件(25),该细长构件以多个匝(27)螺旋缠绕在风扇壳体(24)的内部。 还提出了一种在具有推进风扇(12)的类型的燃气涡轮发动机(10)的风扇壳体装置中安装风扇轨道衬套的方法,所述方法包括:提供风扇壳体(24),提供风扇壳体 柔性和细长的衬垫构件(25),并且以多个匝(27)螺旋地将衬垫构件(25)卷绕到风扇壳体(24)的内部以限定风扇轨道衬套的至少一部分。
