The first stage nozzles of the ERB1 power turbine are, like many early turbines from English Electric and GEC, constructed with individual blades held in a stator mounting-ring. The arrangement reduces cost as only the nozzle blade and the shroud need be in high temperature nickel alloys. The stator ring being remote from the gas path was made in alloy steel, FV448. The stator ring of the ERB1 is necessarily a substantial component and is used to carry the outer section of the turbine inlet duct. As it is exposed to the gas stream this ductwork is made from Hastelloy. This arrangement seemed to work well at first but as the service experience on the ERB1 accumulated, problems appeared with the duct. The rear flange distorted badly, the bolt holes became elongated radially. There was clearly movement between duct and stator ring, differential thermal expansion was too great. The cause was straightforward, the co-efficient of thermal expansion of FV448 is 12x10-6 /OC, for Hastelloy the figure is 18x10-6 /OC. To reduce or eliminate the damage a design change was needed. The degree of damage suggested it must be a fundamental change, and the decision was made to offer a stator ring in Inco 718, material with an expansion coefficient close to 18x10-6 /OC.
In gas turbine aerodynamic design it is normal to set the dimensions of the hot gas path and back calculate the thermal expansions to set the cold dimensions. This ensures each turbine stage has the correct swallowing capacity. Before introducing the change, nozzle expansions were recalculated to ensure acceptable nozzle size. Service bulletin SB/ERB/99-001 gave notice of the change. Recognising that this was a significant change and that a service bulletin is necessarily a brief document, the details of the modification were given in a presentation to users. That presentation was well received and all ERB1 users made the change.
