“…The maximum deformation value is 0.9mm, this value is much less than that of Das et. al [16] where the maximum deformation amplitude is 27.29 mm. The safety factor is 14.77, well above 3 which is the goal.…”

The vibration parameters of a bi-copter-type unmanned aerial vehicle is optimized by considering operational vibration with payloads. The double electric ducted fan loads, which transmit excitations to the fuselage, are predicted and compared using optimization methods. While the minimum vibration amplitude for stress will be achieved at 7.69 Hz, it will be 9.80 Hz. for minimum deformation without sacrificing safety factor requirement. It ensures sensitive vertical acceleration. It is not seen significant differences on results from screening and genetic algorithm methods. Correlations between frequencies and structural responses are determined. It is observed that the stress and deformation amplitudes of the structure decreases at increasing frequencies up to the next natural frequency. While the highest amplitude is seen at the first frequency, it decreases in increasing modes. The airframe structural model's operational frequency must be 7.69 or 9.80 Hz to achieve sensitive vertical acceleration. Subsequently, it is aimed to develop an autonomous task by the implemented system controlled by various algorithm as a future work.

“…The best material was determined as aluminum alloy (6061 T6). Das et al [16] investigated the effect of aluminum alloy material (6061 T6) on the deformation and natural frequency on the landing gear. As a result, the maximum frequency was found to be 974 Hz causing a deflection of 403.59 mm with aluminum alloy (6061 T6).…”

Aircraft are subjected to an impact load during landing. This situation becomes more important for unmanned aerial vehicles that are remotely controlled and must serve in extreme conditions. Because the landing gear should absorb this impact load as much as possible and prevent damage to the unmanned aerial vehicle body and its components. In this study, a landing gear design has been developed for unmanned aerial vehicles that can absorb more impact load during landing. Numerical analyzes were performed to determine the fatigue life and the maximum impact load that the developed design can withstand. In addition, a conventional landing gear was modeled and the results were compared. The properties of 7075-T6 Aluminum alloy were used as the landing gear material. As a result of the finite element analyzes made with Ansys software, it has been understood that the newly designed landing gear can absorb more energy than the conventional landing gear. It has also been determined that it can be used at values up to 3700N impact load.

This paper presents the development, characterization, and testing of PP/PE-g-MA composites with 10 and 15 wt% surface-modified aramid fibers, and aluminum-based pigment, as covers for a small drone body for collision protection. The successful fiber surface modification with SiO2 by the sol–gel method using TEOS was confirmed by FTIR, SEM, and EDS analyses. The composites were characterized by FTIR and SEM analyses and surface energy and water contact angle measurements and tested in terms of tensile, flexural, impact, and thermal properties. The materials exhibited hydrophobic character and compact and uniform morphostructures, with increased surface energy with fiber content owed to improved adhesion between modified fibers and the matrix. Compared to the control sample, composites with modified fibers showed an increase by 20% in tensile strength, and 36–52% in the modulus, and an increase by 26–33% in flexural strength and 30–47% in the modulus, with higher values at room temperature. Impact resistance of modified fiber composites showed an increase by 20–40% compared to the control sample, due to improved interaction between SiO2-modified fibers and maleic anhydride, which inhibits crack formation, allowing higher energies’ absorption. The composites were vacuum-thermoformed on 3D-printed molds as a two-part cover for the body of a drone, successfully withstanding the flight test.
