Turbomachinery Design Special Projects

Case Study 1

A jet engine manufacturer retained SoftinWay to perform an assessment of a design of a low pressure turbine, and to determine any potential ways to improve the design while keeping the outer casing dimensions the same.

Using AxSTREAM, SoftinWay engineers were able to redesign the flow path while maintaining the same flow characteristics and power output. The new design eliminated one complete stage (from 7 to 6), which resulted in a 15 percent weight reduction of the turbine. The new design was fit within the overall engine configuration (mean diameters of the first and last stages) and efficiency was increased to 94%.

Case Study 2
A service company for turbomachinery asked SoftinWay to perform a redesign of LP steam turbine for the purpose of flow path improvement and capacity increase, while keeping the outer and axial casing dimensions the same.

Using AxSTREAM, SoftinWay engineers were able to redesign the flow path. The LP turbine capacity was increased 16% (from 347 to 401 kW), even while the design inlet pressure was decreased from 1.29 to 0.97 bar.
