“…The use of the Blade Element Theory (BEM) formula in calculating thrust in this study still uses many assumptions that make this formula simpler than the actual BEM formula, where the BEM formula actually Endurance estimation in hovering flight based on battery power requested on quadcopter UAV contains slightly more parameters than the BEM formula used in this study one of those parameters is flow angle φ [11]. Since the calculations of endurance in this study use the steps and parameters available in this literature [6]. The results of the endurance calculation from this study can be said to be quite satisfying, however, this study would be better if we did an experimental flight on a drone to compare the calculation results with the actual results.…”

In this era, Unmanned Air Vehicle (UAV) application is growing. However, there are still weaknesses in using UAVs to carry out certain missions. One of the major problems is the energy and power required to use the UAV which impacts the endurance of a UAV can hover. This study focuses on calculating the endurance and finding which configuration will produce the optimal endurance. It starts by calculating the thrust of a propeller using blade element theory which ends in calculating endurance. Using four different types of propellers, an integral formulation was devised for a constant–power battery discharge process to predict the hovering time. The result shows that APC 1238 combined with battery 6S will produce the longest endurance. The methodology is applicable for a custom quadcopter UAV.

“…For instance, as detailed in subsequent sections, the current study necessitated a comprehensive design process for the multirotor's flight control subsystem and airframe. Other studies, such as 6 , 26 , 27 , focus solely on one or two specific subsystems or components and the associated discipline. The propulsion subsystem, which typically includes propellers, brushless DC electric (BLDC) motors, electronic speed control (ESC), and batteries, is often the primary focus.…”

In this study, a novel multirotor configuration has been developed, which utilizes a coaxial counter-rotating propeller with a large diameter at the center and four propellers with smaller diameters on four arms in an X configuration. The research pursues two main objectives. The first objective is to establish a development method for multirotors based on the well-known V-method approach in system development. The proposed method enables the design team to analyse and evaluate the multirotor at each stage of the design process, from the system to the component level, and improve the design with greater speed and accuracy. Additionally, the proposed approach can be integrated with various optimization methods, if necessary, to achieve an optimal design. The second objective is to provide the proof-of-concept of the novel multirotor configuration. This objective is pursued across different evaluation sections, from evaluating individual components to fully evaluating the multirotor, to assess the performance of this novel configuration and identify its advantages and disadvantages. The results of various evaluations demonstrate the proposed development process's practicality and proves that the novel configuration is operational and competitive with conventional multirotors in various applications.

“…Although multiple installations of batteries are possible to extend the flight endurance, the weight of multirotor drones certainly increases as well as the payload decreases. de Angelis et al (2021) estimated the hover performance of a battery-powered multirotor drone from blade shape parameters and battery discharge process. To improve the flight endurance, we developed the possible efficient propeller design for a hover and presented the effectiveness of the propeller design in previous studies (Oda, 2017;Murakami et al, 2018Murakami et al, , 2019.…”

The effects of cross flow and fluctuating cross flow on the aerodynamic performance of multirotor drone propellers were investigated by using wind tunnel testing and numerical simulations. Three hovering propellers were examined and were designed based on Adkins and Liebeck theory with modifications. Thrust coefficient 𝐶 and power coefficient 𝐶 of each propeller were experimentally measured and Figure of Merit 𝐹𝑀 was evaluated. From the cross flow experiments and numerical simulations, 𝐶 , 𝐶 and 𝐹𝑀 calculated were in reasonable agreement with the experimental results at high cross flow velocity. The results implicated that a stall might occur at near the root of the propeller as well as demonstrated that the starting point of the propeller design played a role in aerodynamic performance under the cross flow conditions. Moreover, from the fluctuating cross flow experiments, 𝐶 , 𝐶 and 𝐹𝑀 fluctuated in time and the propellers are more susceptible to cross flow and fluctuating cross flow at lower rotational speed in terms of the amount of change of aerodynamic forces.
