“…A conventional 100 W solar panel was used during the ground tests, but the C60 model of the Sunpower brand, which is frequently used in mini-UAVs, is planned to be used in detailed design and assembly stages. One of the C60 models weighs 7 g and generates about 3.5 W with 22.5% efficiency (Sri et al , 2016). It also consists of a very thin structure that can flex up to an angle of 30°.…”

Purpose The endurance of small unmanned air vehicles (UAVs) is directly associated with the energy density of the propulsion system used. As the batteries commonly used in small UAVs have a relatively low energy density, they are not sufficient for long-term endurance tasks. The purpose of this paper is to offer a solution to increase the endurance of a concept small UAV with combination of different power sources. The design, construction and ground tests of fuel cell-powered hybrid propulsion systems are presented in this paper. Design/methodology/approach The power requirements of a concept UAV were calculated according to aerodynamic calculations and then, hybrid propulsion system sources are determined. The hybrid system consists of a 100 W scale proton-exchange membrane (PEM) type fuel cell stack, lithium-polymer battery, solar cells and power management system (PMS). Subsequently, this hybrid power system was integrated with the new design of PMS and then series of ground tests were carried out. Findings This experimental study proved that it is theoretically possible to obtain an endurance of around 3 h for concept UAV with the proposed hybrid system. Practical implications The research study shows that fuel cell-based hybrid propulsion system with the proposed PMS can be widely used to obtain extended endurance in small UAVs. Originality/value A hybrid propulsion system with a novel PMS unit is proposed for small UAVs and the ground tests were implemented.

“…The fixed mass includes the masses of the payload and avionics. These masses are known and do not vary with the aircraft's dimensions: m f ixed = m av + m pld (8) where m f ixed is fixed mass, m pld is payload mass and m av is avionics mass.…”

This paper presents a novel framework for the design of a low altitude long endurance solar-powered UAV for multiple-day flight. The genetic algorithm is used to optimize wing airfoil using CST parameterization, along with wing, horizontal and vertical tail geometry. The mass estimation model presented in this paper is based on structural layout, design and available materials used in the fabrication of similar UAVs. This model also caters for additional weight due to the change in wing airfoil. The configuration is optimized for a user-defined static margin, thereby incorporating static stability in the optimization. Longitudinal and lateral control systems are developed for the optimized configuration using the inner–outer loop strategy with an LQR and PID controller, respectively. A six degree-of-freedom nonlinear simulation is performed for the validation of the proposed control scheme. The results of nonlinear simulations are in good agreement with static analysis, validating the complete design process.

“… Explore solar energy: Installing solar panels in UAVs could greatly increase flight times. There have been some initiatives to mount solar panels in fixed-wing UAVs (Anderson and Gaston, 2013; Sri et al, 2016), and there are some companies, such as Alta Devices (Sunnyvale, California, USA), that are investing in this technology.Although considerable progress has been made for large UAVs, the application of this technology to small UAVs is still too incipient to be used in practical applications. …”

The use of unmanned aerial systems (UASs) in agriculture has been growing steadily in the last decade, but their use to monitor and count cattle has been very limited. This article analyses the reasons for this apparent lack of progress, considering both the technical challenges and the difficulties in defining target users who would benefit from a UAS-based system for monitoring cattle. Such an analysis is combined with the findings reported in several investigations dedicated to counting and monitoring wildlife to draw a comprehensive picture on the current situation, to suggest possible solutions to technical issues and to delineate applications that could be useful to both cattle farmers and governments. The text concludes by showing that there are unexplored viable uses for UAS in livestock monitoring, especially in countries like Brazil, where extensive stockbreeding prevails.
