“…The number of rotors has a significant impact on a UAV's performance. Increased rotary wings, for instance, enhance thrust, combat safety, and maneuverability [21]. The most advanced type of commercial UAVs available today, octa-rotors are primarily utilized for heavy load applications [22].…”

“…The energy consumption is relatively significant despite their great maneuverability, which results in restrictions on flying range, speed, and carrying capacity. When fixed wing structures are added to a rotary-wing UAV, the lift produced by the surfaces of the fixed wings can significantly increase the UAV's operational performance [21]. The lifting wing rotor-wing UAV is designed at a fixed installation Angle between the rotor blade plane and the lifting wing, which not only retains the original clean and reliable structure of the rotary-wing UAV, but also improves the forward flight efficiency.…”

Due to their advantages in hovering, takeoff and landing adaptability, maneuverability, and other factors, rotary-wing unmanned aerial vehicles (UAVs) are widely applied across many different fields. The UAVs' design and configuration can be quite flexible to fit diverse operation conditions. The major goal of innovations in rotary-wing UAVs is to lower operating risk and expense by optimizing payload and structure layout. This study examines three aspects of rotary-wing UAV design and evolution: the number and arrangement of rotors, hybrid-wing-based UAVs, and configuration and loading structures. The most current advancements of UAV applications in crucial industries, including agriculture, fire rescue, inspection and monitoring, and aerial logistics, are then thoroughly examined. Finally, the authors discussed the prospective uses for rotary-wing UAV design in the future.

“…The UAV is considered a cooperative rigid object with a simple autopilot that maintains a constant trajectory to the landing area. UAVs are also evolving with the development of new structural designs [26], new materials [27], new payloads [28,29], and optimized radar cross-sections [30]. The ship is also considered cooperative and performs maneuvering to adjust the relative speed of the UAV and, consequently, the relative wind.…”

The vast increase in the available computational capability has allowed the application of Particle-Filter (PF)-based approaches for monocular 3D-model-based tracking. These filters depend on the computation of a likelihood function that is usually unavailable and can be approximated using a similarity metric. We can use temporal filtering techniques between filter iterations to achieve better results when dealing with this suboptimal approximation, which is particularly important when dealing with the Unmanned Aerial Vehicle (UAV) model symmetry. The similarity metric evaluation time is another critical concern since we usually want a real-time implementation. We explored, tested, and compared with the same dataset two different types of PFs, (i) an Unscented Bingham Filter (UBiF) and (ii) an Unscented Bingham–Gauss Filter (UBiGaF), using pose optimization in both implementations. Using optimization steps between iterations increases the convergence capability of the filter and decreases the obtained error. A new tree-based similarity metric approach is also explored based on the Distance Transform (DT), allowing a faster evaluation of the possibilities without losing accuracy. The results showed that the obtained pose estimation error is compatible with the automatic landing requirements.

“…Nowadays, the advancement of science and technology has greatly promoted the wide use of UAVs. From the structural point of view, UAVs mainly include four types: fixed wing, rotating flapping wing, hybrid wing, and gas envelope [1], and it plays a huge role in high-altitude pesticide spraying, agricultural, forestry spectral monitoring, vertical take-off landing military monitoring, transportation of rescue materials, obstacle sensing, and satellite cooperative communication [2][3][4][5][6][7].…”

With the extensive application of UAVs in various fields, it becomes more important to design a routing protocol that ensures stable transmit between UAV groups. This is because UAV groups are densely packed, move fast, and communication links are fragile. Aiming at the intensive and highly maneuverable UAV group, the AODV-NLS-ETX—a routing protocol based on the link stability of neighbor nodes—is proposed on the basis of the ETX metric based AODV protocol. The protocol is simulated and compared with other protocols. The simulation results show that AODV-NLS-ETX is superior to other protocols in packet delivery rate and throughput under high shift speed, dense nodes, and high routing overhead. It can effectively reduce the high delay brought by the ETX mechanism. The delay is the most stable and is not easy to cause network congestion. It can be better applied to dense and highly mobile unmanned aerial vehicles.
