Abstract Global energy scenario requires thermal systems with higher efficiency and lower capital and operating cost. The paper deals with the thermoeconomic analysis of the gas turbine cycles with possible application as marine gas turbines. Thermoeconomic analysis of an energy conversion cycle is a combined study of thermodynamics and economics. Different configurations of gas turbine cycles have been analyzed using thermo-economic methodology keeping the gas turbine operating parameters (compressor pressure ratio, turbine inlet temperature, isentropic efficiencies of compressor & turbine etc fixed. Study has been carried out by considering appropriate objective function in a form of decision variables. This objective function combines both fuel cost and investment cost.

Abstract In modern complex engine design, it is a common challenge to keep simulation in step with changes to component geometry, environmental conditions, and mission data - and this applies to both actual designs and those that belong to the hypothetical design space as explored in design of experiments (DOE). In this paper, an effective simulation process and data management (SPDM) approach is presented that hinges on a focus on components, their generalized connections and programmatic templating. This simulation approach improves the fidelity of engine analysis, engineering productivity, quality, scalability across the gas turbine engine organization, and HPC utilization. In addition to this new analysis machinery, gas turbine engine modeling fidelity is elevated by surpassing commonly used one-dimensional (1D) models of rotors.

This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of turboprop and turboshaft engines. This Aerospace Recommended Practice (ARP) shall apply to both dynamometer and propeller based testing. Test cell correlation is performed to determine the effect of any given test cell enclosure and equipment on the performance of an engine relative to the baseline performance of that engine. Although no original equipment manufacturer (OEM) documents are actually referenced, the experience and knowledge of several OEMs contributed to the development of this document. Each engine manufacturer has their own practices relating to correlation and they will be used by those OEMS for the purpose of establishing certified test facilities.

This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of APU (auxiliary power unit) engines. Test cell correlation is performed to determine the effect of any given test cell enclosure and equipment on the performance of an engine relative to the baseline performance of that engine. The baseline performance is generally determined at the original equipment manufacturer (OEM) designated test facility. Although no original equipment manufacturer (OEM) documents are actually referenced, the experience and knowledge of several OEMs contributed to the development of this document. Each engine Manufacturer has their own practices relating to correlation and they will be used by those OEMs for the purpose of establishing certified test facilities.

This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of turbofan and turbojet engines. Test cell correlation is performed to determine the effect of any given test cell enclosure and equipment on the performance of an engine relative to the baseline performance of that engine. When baseline testing is performed in an indoor test cell, the baseline performance data are adjusted to open air conditions. Although no original equipment manufacturer (OEM) documents are actually referenced, the experience and knowledge of several OEMs contributed to the development of this document. Each engine Manufacturer has their own practices relating to correlation and they will be used by those OEMS for the purpose of establishing certified test facilities.
