A vertical take-off and landing (VTOL) is a type of unmanned aerial vehicle (UAV) that allows for flight in harsh weather surveillance access to remote areas. VTOL can be performed without runway. As such, VOTL UAVs are used areas where there limited space urban locations. The structural endurance further reduced the case fixed-wing UAVs. Long-endurance vehicles allow continuous flight, but the...

UAV aircraft with a fixed wing configuration multi-rotor are capable of vertical take-off and landing (VTOL). In designing the structure aircraft, weight factor strength factors that need to be considered. The use sandwich composite materials on wings is expected able meet requirements namely having light weight, high rigidity strength. this study, comparative analysis balsa wood VTOL VX-2 was ...

A vertical take-off and landing plane (VTOL plane) is a fixed-wing unmanned aerial vehicle (FWUAV) configuration with the ability to take off land vertically. It combines benefits of multirotor configurations, which gives it high cruising range independence from runway. This requires arms as mountings for VTOL’s motors. study discusses design VTOL Plane various arm computational fluid dynamics ...

The design of low-cost and efficient configurations of UAV (Unmanned Aerial Vehicle) becomes increasingly more important for improving the performances, flight characteristics, and increase of a payload. Ability of vertical take-off and landing is a challenging but important task for the UAV to achieve a high level of autonomy. The fundamental requirement for vertical take-off or landing is the...

With UAVs becoming increasingly popular in the industry, vertical take-off and landing (VTOL) convertiplanes are emerging as a compromise between advantages of planes multicopters. Due to their large wing surface area, VTOL subject strong wind dependence on critical phases such take-off, landing, hovering. Developing new improved unmanned aerial vehicle (UAV) is often expensive associated with ...

Inventive approaches are constantly being revealed in the field of vertical take-off and landing (VTOL) unmanned aerial vehicle (UAV) configuration concepts designs. To date, a body-associated UAVs for augmented lift remains unclear among other approached The current paper investigates mechanism high-lift ducted fan mounted central body VTOL UAV We report an unresolved design disc-shaped with s...

Aiming at the vertical take-off and landing mode of tilt-propulsion UAV with uncertainties such as external environment disturbance internal parameter perturbation, this paper studies trajectory tracking control, proposes an double loop sliding control scheme based on nonlinear extended state observer (NLESO). Firstly, according to characteristics UAV, dynamic model propulsion system, aerodynam...
