Object-oriented Turbomachinery Analysis Code (OTAC)

About this technology

Overview

The OTAC software is a set of interpreted objects that extend the capabilities of the NPSS software framework to allow for design and analysis of turbomachinery. OTAC allows for user specification of various gas compositions as the working fluid. The user also has flexibility in selecting loss models, deviation models, and blockage models, and can create and apply their own such correlations.OTAC is an engineering research tool still in development with new features being added and existing features refined.NPSS is the Numerical Propulsion System Simulation code; it performs 1-D thermodynamic cycle analysis of gas turbine engines. Access to NPSS is required to run the OTAC software.
