Abstract

Hybrid powerplants combining Internal Combustion Engines (ICE) and Electric Motor (EM) prime movers have been extensively developed for land and marine based transport systems. The use of such powerplants in airborne applications has been historically impractical due to energy and power density constraints. Improvements in battery and electric motor technology make aircraft hybrid powerplants feasible. This paper presents a technique for determining the feasibility and mechanical effectiveness of powerplant hybridisation. In this work a prototype Aircraft Hybrid Powerplant (AHP) was designed, constructed and tested. It is shown that an additional 35% power can be supplied from the hybrid system with an overall weight penalty of 5%, for a given UAS. A flight dynamic model was developed using the AeroSim™ Blockset in MATLAB® Simulink®. The results have shown that climb rates can be improved by 56% when using the hybrid powerplant concept, with a standard propeller design.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
