Abstract

NASA Armstrong Flight Research Center (AFRC) is currently conducting research on electric propulsion technologies through the Hybrid Electric Integrated Systems Test-Bed (HEIST) project. The goal of the HEIST project is to research hybrid distributed electric propulsion by utilizing a hardware test-fixture to explore optimal flight control systems as well as overall system efficiency. The HEIST propulsion team was tasked with selecting and modeling a turbo-generator that feeds power into a hybrid system of batteries and a distributed bank of motors. Numerical Propulsion System Simulation (NPSS) is an advanced aero-thermo simulation language developed by NASA in conjunction with the Arnold Engineering Development Complex (Arnold Air Force Base, Tennessee), Honeywell, Rolls Royce-Allison, The Boeing Company, General Electric, and Pratt & Whitney. NPSS enables modeling and simulation of entire propulsion systems in order to study steady-state and transient engine performance and behavior under desired flight conditions. A Capstone C65 microturbine engine (Capstone Turbine Corporation, Chatsworth, California) was chosen by the HEIST team and is currently being modeled using NPSS. The C65 model is performing promisingly and is being integrated into MATLAB®-Simulink® (The MathWorks, Inc., Natick, Massachusetts) using the NPSS S-Function to enable compatible simulation with battery and control system models. The model will provide predictions for the real-time testing of the entire hybrid electric system with future plans to be connected to a flight simulator.
