Purpose This paper aims to present the main results achieved in the frame of the TIVANO national-funded project which may anticipate, in a stepped approach, the evolution and the design of the enabling technologies needed for a hybrid/electric medium altitude long endurance (MALE) unmanned aerial vehicle (UAV) to perform persistent intelligence surveillance reconnaissance (ISR) military operations. Design/methodology/approach Different architectures of hybrid-propulsion system are analyzed pointing out their operating modes to select the more suitable architecture for the reference aircraft. The selected architecture is further analyzed together with its electric power plant branch focusing on electric system architecture and the selected electric machine. A final comparison between the hybrid and standard propulsion is given at aircraft level. Findings The use of hybrid propulsion may lead to a reduction of the total aircraft mass and an increase in safety level. However, this result comes together with a reduced performance in climb phase. Practical implications This study can be used as a reference for similar studies and it provides a detailed description of propulsion operating modes, power management, electric system and machine architecture. Originality/value This study presents a novel application of hybrid propulsion focusing on a three tons class MALE UAV for ISR missions. It provides new operating modes of the propulsion system and a detailed electric architecture of its powertrain branch and machine. Some considerations on noise emissions and infra-red traceability of this propulsion, at aircraft level.

Increasing numbers of motorcycles are causing urban source of unregulated pollutants which are hazardous to environment and human health. Hybrid electric motorcycle (HEM) could be a solution to the problem as the electric system operates at high efficiency, allow diversification of energy resources, zero local emission and work silently. A HEM with parallel drive-train configuration has better fuel economy but post complex drive-train. In this paper, a parallel drive-train is proposed where two numbers of one way clutch are used to isolate the power source components when operating at different speed. The parallel drive-train allows the control unit to utilize and manage the power sources efficiently by operating at various modes based on the driving requirement. Meantime, maximum torque is available in blended mode when the internal combustion engine and electric motor operate simultaneously. The proposed drive-train posts the advantages of being simple, low cost and ease for control design for a HEM.
