“…The cylindrical shape of a stationary fluid zone is employed to mimic a significant portion of the surrounding air to create a realistic simulation. This setup is in line with several previous research(Stokkermans et al, 2020;Kim, D. et al, 2021; Li, Y. et al, 2023). It is possible to select a domain that is sufficiently extensive to avoid affecting the results.…”

Drones have a major drawback which prevents them from being used extensively - the excessive noise they produce. This article presents an optimization process of aerodynamic noise reduction for a novel design called the Toroidal Propeller, which consists of two blades looping joined in a manner where the end of one blade arches back into the other, has been designed by the Aerospace Propulsion Systems (APSs) research team at School of Mechanical Engineering, Hanoi University of Science and Technology. In addition, four toroidal propellers with different curved shapes (pitch) and Number of Blades (NOB) are considered. The goal of this research is to evaluate the effects of modifying the geometry design of the Toroidal Propeller on the intensity of blade tip vortex and aerodynamic flow characteristics passing through the blade. The ultimate goal is to decrease blade tip vortex and turbulence produced by the blade, which can help estimate the sound pressure level and minimize it without causing significant performance losses. Based on the outcome results, the models of the four geometry studies are compared in terms of Acoustic Power Level (APL), Surface Acoustic Power Level (SAPL), Thrust, Torque, and Power. In general, the propeller model with NOB of 3 provides the most optimal efficiency in terms of both Thrust and APL. At the output cross-section, the APL dropped from nearly 139 dB to 121 dB, while thrust increased from almost 6.2N to 8.7N compared to the first version of the Toroidal Propeller model.

The growing popularity of multicopters has heightened interest in improving and optimizing UAVs. This has become a major source of inspiration for scholars. Extensive aerodynamics research would result in improved multicopters and boost their appeal to major sectors. Various aspects of the performance of various propeller designs and configurations have been studied by researchers. Various performance metrics have also been investigated and discussed in this paper. Aerodynamic testing of propellers and multicopter designs are discussed in this paper. Numerical simulations are also used widely in the study of drone and multicopter aerodynamics. This method enables high resolution observation on wake propagation and flow visualizations. Nonetheless, as new multicopter concepts are introduced, new aerodynamic challenges emerge in this field. Therefore, more studies need to be done on uncommon but rather important configurations so that these can have a beneficiary effect on the multicopter industry.

“…Even though Sinnige et al (2021) conducted a comparative experimental study on the tip-mounted tractor and pusher configurations, flow field and surface flow details were not studied. Stokkermans et al (2019), Kim et al (2021) and Minervino et al (2022) used cost-effective actuator disk methods to study the flows involving propeller. The present study compares the wing with tip-mounted propellers in tractor and pusher configurations.…”

Purpose Recent interest in electric aircraft has opened avenues for exploring innovative concepts and designs. Because of its potential to increase wing aerodynamic efficiency, the idea of wing tip-mounted propellers is becoming more popular in the context of electric aircraft. This paper aims to address the question of which configuration, tractor or pusher at wing tip is more beneficial. Design/methodology/approach The interactions between the wing and tip-mounted propellers in tractor and pusher configurations have been studied computationally. In this study, the propeller is modeled as a disk, and the blade element method (BEM) coupled with the computational fluid dynamics (CFD)–Reynolds-averaged Navier–Stokes (RANS) solver is used to calculate propeller blade loading recursively. A direct comparison between the wing with tip-mounted propellers in tractor and pusher configurations is made by varying the direction of rotation and thrust. Findings Wing with tip-mounted propellers having inboard-up rotation is found to offer less drag in tractor and pusher configurations than those without propeller cases. Wing tip-mounted propeller in tractor configuration with inboard-up rotation offers higher wing aerodynamic efficiency than the other configurations. In tractor and pusher configurations with inboard-up rotating propellers, wing tip vortex attenuation is seen, whereas with outboard-up rotating propellers, the wing tip vortex amplification is observed. Originality/value SU2, an open-source CFD tool, is used in this study and BEM is coupled to perform RANS–BEM simulations. Both qualitative and quantitative comparisons were made between the tractor and pusher configurations, which may find its value when a question arises about the aerodynamically best propeller configuration at wing tips.
