Modelling and Analysis of an Aircraft On-board Electric Taxiing System

Abstract

This paper presents a model that enables analysis and design validation of an aircraft on-board electric taxiing system. A detailed model, which includes power electronics, electrical machine and mechanical drivetrain, is first developed and discussed. The model is then employed for simulating two characteristic taxiing mission profiles with a Boeing 737-400 as a selected benchmark aircraft. From the simulation findings, acceleration performance, power and energy load profiles, as well as the energy harvesting stages are studied. These outcomes allow to evaluate the appropriate energy storage technology to be selected, enabling complete emission free aircraft taxiing.
