A turbine with multiple gas inlets is designed by a process of, for a given engine, obtaining time series data characterizing the power bias of the engine, obtaining an isentropic power associated with each data point of the time series, and using the isentropic powers to obtain a design point. The turbine is then designed based on the design point, such as by optimising one or more design parameters of the turbine based on the design point.

Method of designing and producing a turbine

There is provided a diffuser for a turbine, comprising: a support configured to mount to a turbine housing; a diffuser body configured to receive fluid from an outlet of the turbine, the diffuser body defining a longitudinal axis and having a perimeter with a length measured in a plane normal to the longitudinal axis; and a bridge configured to connect the support to the diffuser body, wherein the connection between the bridge and the diffuser body is confined to a continuous portion of the perimeter of the diffuser body that is not more than around 50% of the total length of the perimeter of the diffuser body.
