Definitions

  • Fig. 1 illustrates an arrangement 10 for providing thermal energy from a heat source 12 to a component 14 of a gas turbine engine.
  • the component 14 comprises a portion 16 that is heated by the heat source 12 via an elongate member 18.
  • the elongate member 18 is connected to the portion 16 and shaped so that there is a net thermal energy input into the portion 16, to increase the temperature of the portion 16, while the component 14 is forming.
  • the elongate member 18 increases in cross sectional area from the join between the elongate member 18 and the portion 16 (base) to define a trapezium shape as illustrated in Fig. 1.
  • Fig.3 illustrates the arrangement of Fig.1 when viewed along direction B.
  • the elongate member 18 is substantially rectangular when viewed in the direction B. It can also be seen from Fig. 3 that the second surface area component 36 has a greater surface area than the third surface area component 34.
  • the elongate member 18 is, in this example, approximately 25mm long and 3mm deep.
