“…The drone's structural design might prioritize rigidity and stiffness, which could lead to higher stress levels during testing. While higher stress levels may indicate the ability to withstand applied loads, it could also suggest that the drone is less flexible and more susceptible to structural damage [15][16]. Therefore, Design 1 has been selected for topology optimization and subsequent fabrication due to its favorable performance characteristics, including lower velocity in the flow simulation, higher stress levels, and lower displacement in the stress analysis.…”

“…However, it is essential to acknowledge that in direction 3, Design 3 outperformed the other designs, attaining a remarkable velocity of 30.794 m/s, whereas Design 1 lagged behind with a velocity of 24.43 m/s. This divergence highlights the significance of considering the directionspecific performance of drone frames, as various flight scenarios may require distinct design optimizations [16]. The variations in velocity among the designs can be attributed to their differing aerodynamic features, including the shape of the body and wings.…”

“…Drone 1 exhibited higher velocity in the flow simulation but also showcased higher stress levels and the lowest displacement in the stress analysis. This correlation suggests that the aerodynamic advantages of Drone 1 may be associated with its structural rigidity [14][15][16]. It's important to recognize that a drone's structural design often involves a trade-off between rigidity and flexibility.…”

This study focuses on the analysis and optimization of a drone frame design to enhance its performance characteristics. The design underwent drop testing, stress analysis, displacement analysis, and flow simulation to evaluate its structural integrity, deformation resistance, and aerodynamic performance. Furthermore, topology optimization techniques were employed to achieve a 30% weight reduction while maintaining the structural integrity of the drone frame. The results of the drop test analysis revealed that Design 2 exhibited lower stress levels compared to Design 1, indicating improved load distribution and structural integrity. However, Design 1 demonstrated lower displacement values, suggesting better resistance to deformation. The flow analysis indicated that Design 1 achieved lower flow velocities, indicating superior propulsion and aerodynamic performance. Through topology optimization, the mass of the drone frame was successfully reduced by 30% without compromising structural integrity. The optimized design exhibited improved stress management, reduced displacement, and slightly higher flow velocities compared to the initial design. These improvements contribute to enhanced agility, maneuverability, and energy efficiency of the drone. The findings of this study highlight the importance of considering stress distribution, displacement, and aerodynamic performance in drone design and optimization. The results provide valuable insights for the development of efficient and reliable drones.

“…The components examined in the specific context investigated in this paper underwent meshing using the FEA method for static analysis. Meshing is an important step in FEA because it involves the discretization of complex geometries into smaller elements, which affects the accuracy and efficiency of subsequent numerical simulations [52]. The static analysis starts by applying a force to the relevant regions of the mechanically meshed system equivalent to the anticipated real-world conditions.…”

Our study introduces a new approach, leveraging robotics technology and remote sensing for multifaceted applications in forest and wildfire management. Presented in this paper is PULSAR, an innovative UAV with reconfigurable capabilities, able of operating as a quadcopter, a co-axial quadcopter, and a standalone octocopter. Tailored to diverse operational requirements, PULSAR accommodates multiple payloads, showcasing its adaptability and versatility. This paper meticulously details material selection and design methods, encompassing both initial and detailed design, while the electronics design section seamlessly integrates essential avionic components. The 3D drone layout design, accomplished using SOLIDWORKS, enhances understanding by showcasing all three different configurations of PULSAR’s structure. Serving a dual purpose, this study highlights UAV applications in forest and wildfire management, particularly in detailed forest mapping, edge computing, and cartographic product generation, as well as detection and tracking of elements, illustrating how a UAV can be a valuable tool. Following the analysis of applications, this paper presents the selection and integration of payloads onto the UAV. Simultaneously, each of the three distinct UAV configurations is matched with a specific forest application, ensuring optimal performance and efficiency. Lastly, computational validation of the UAV’s main components’ structural integrity is achieved through finite element analysis (FEA), affirming the absence of issues regarding stress and displacement. In conclusion, this research underscores the efficacy of PULSAR, marking a significant leap forward in applying robotics technology for wildfire science.

“…Because higher drag will reduce flight efficiency, from an aerodynamic point of view, drag will affect fuel consumption in flight operations which requires propulsion to work harder so that fuel requirements increase [6]- [8], this will also lead to emission pollution problems [9] and noise caused by aerodynamic noise [10]. The part of the aircraft that is used to process the force generated by the aerodynamic shape is the wing of the aircraft, so it is very  ISSN: 2088-8694 important to pay attention to aerodynamic efficiency in this section [11]. This statement shows that the shape of wings can improve the efficiency and aerodynamic of the aircraft.…”

This journal discusses the implementation and testing of the electrical morphing wing system on light aircraft prototypes, namely technology on the wing to increase the value of aerodynamic efficiency on the wing surface with experimental methods based on knowledge obtained from various literature sources. Using a configuration of eight servo actuators arranged in parallel for the aileron and flap functions as well as setting and control with a six-channel Flysky-FSi6 remote to control the movement of the master and slave aileron actuators as well as the flap function on the morphing wing. The design includes the layout of the actuator, setting commands on the remote and wiring system electrical components. Other aspects such as rib design, mechanism and material selection affect the overall distribution of motion produced by the servo actuator. Through the design of the electrical system morphing wing design on the prototype aircraft, it is proven to be able to support the needs of the morphing wing motion mechanism with the concept of an arrangement of eight actuators in parallel on the rib morphing wing. It is hoped that the concept of the morphing wing can be implemented and further developed so that it can be used on full-scale aircraft.
