TurboGenerator & SiC Inverter Modeling with an NPSS/ngSPICE DLL Interface

Event Center BC

The new hybrid-electric propulsion system combines the traditional gas turbine engine with an electrically powered motor/ generator. This system can benefit from both the practicality of a gas turbine engine and the efficiency of electrical components. The reduction of fuel consumption, takeoff noise and harmful emissions are all improvements this hybridelectric propulsion system can provide. There are many ways to begin understanding the coupled nature of these two distinct systems. NPSS (Numerical Propulsion System Simulations) is a computer software program which can help analyze the thermodynamic properties of the gas turbine engine portion of the propulsion system. To create a practical hybrid propulsion system, focus has been centered on the conversion of mechanical energy in the turbine section to electrical energy. The energy and various other properties can be quantified with NPSS in order to move on towards the actual conversion between energy states. This project will not only contribute towards building a foundation for hybrid-electric aircrafts but as well as help the HEIST (Hybrid-Electric Integrated Systems Testbed) project at NASA Armstrong.
