“…The manufacturer, Diamond Aircraft, indicates a potential 25% decrease in fuel consumption. The series configuration has been shown to be unsuitable for RPAS/UAS applications, where it was estimated that a small UAV would result in an 8%, or 2.5 lb (1.13 kg), weight penalty for a 30-lb (13.61 kg) UAS [55].…”

The development of more efficient propulsion systems for aerospace vehicles is essential to achieve key objectives. These objectives are to increase efficiency while reducing the amount of carbon-based emissions. Hybrid electric propulsion (HEP) is an ideal means to maintain the energy density of hydrocarbon-based fuels and utilize energy-efficient electric machines. A system that integrates different propulsion systems into a single system, with one being electric, is termed an HEP system. HEP systems have been studied previously and introduced into Land, Water, and Aerial Vehicles. This work presents research into the use of HEP systems in Remotely Piloted Aircraft Systems (RPAS). The systems discussed in this paper are Internal Combustion Engine (ICE)-Electric Hybrid systems, ICE-Photovoltaic (PV) Hybrid systems, and Fuel-Cell Hybrid systems. The improved performance characteristics in terms of fuel consumption and endurance are discussed.

“…This work made large strides in the UAV parallel hybrid design space that involved conceptual design work, simulation, and control strategy development by several groups. The initial designs from this group predicted that hybrid-electric propulsion systems could reach efficiencies of 94% (Harmon et al 2005;Hiserote 2010;Hiserote and Harmon 2010). The University of Colorado has shown success with their project HELIOS, which also made use of a parallel hybrid architecture in their UAV (Koster et al 2011).…”

“…In a study conducted by Harmon et al (2005), it was estimated that a parallel configuration on a small UAV would be approximately 8% lighter than a series configuration. The difference in mass can be largely contributed to the requirement of both a large electric motor and generator of the series configuration.…”

The transition to cleaner, more efficient and longer-endurance aircraft is at the forefront of research and development in air vehicles. The focus of this research is to experimentally evaluate hybrid propulsion and energy harvesting systems in unmanned aerial vehicles (UAVs). Hybrid systems offer benefits over conventional gasoline and electric systems including lower environmental impacts, reduced fuel consumption, redundancy, and distributed propulsion. Additional energy efficiency can be achieved by harvesting some of the thermal energy of the exhaust gases. The development and experimental evaluation of a hybrid propulsion UAV was carried out at the University of Victoria Center for Aerospace Research (UVIC-CfAR) in the framework of the Green Aviation Research & Development Network (GARDN) grant. The work involved the development of a framework to evaluate UAV hybrid propulsion efficiency, and to predict the amount of power harvestable from thermoelectric generators (TEGs). The objective was to combine all of the components into a modular test bench that will allow the performance of the parallel hybrid system to be characterized and compared with theoretical results. Several experiments were performed to collect performance data of various components including a triple-TEG system connected to an engine, and system variables were modified to simulate flight profiles.
