Abstract

Hybrid-Electric aircraft powertrain modeling for Unmanned Aerial Systems (UAS) is a useful tool for predicting powertrain performance of the UAS aircraft. UAS aircraft utilize small-displacement engines that have poor thermal efficiency and as a result, could benefit from a hybridized powertrain by reducing fuel consumption. The scope of this work aims to provide a tool that can allow one to estimate the hybrid powertrain performance based upon the aircraft specifications, component specifications, propulsion component performance maps, and mission power profiles. Utilizing MATLAB, a powertrain model will be developed that can facilitate system performance testing for a given mission profile, as well as component sizing which will allow for optimized powertrain power consumption in addition to aircraft range and endurance.
