Subsystem Integration for Efficient Power Flow in 21st Century Airlifters

Abstract

In this report we are concerned with modeling, simulation and dynamic stability of next generation DC power distribution systems for 21st century airlifters. These new power distribution systems allow for two way power flow between the generator, power distribution system, and loads (actuators, avionics, environmental control system). This two way power flow implies that all of these subsystems dynamically interact with each other. An extensive simulation block library was developed including models of generators, power converters, filters, and electromechanical and electrohydraulic actuators. A methodology based on bifurcation analysis for investigating the dynamic stability of two nonlinear subsystems is also presented.
