摘要:Abstract- Unmanned Aircraft System (UAS) has become a useful robotics system for variety of applications. Vertical take-off and landing (VTOL) multi-rotor Unmanned Aerial Vehicles (UAVs) take the advantage of convenient to fly without environment constraints. However, multi-rotor UAVs are limited with maximum takeoff weight (MTOW) and flight endurance under moderate meteorological conditions. While in some special applications, water landing is taken into account, the wing-in-ground-effect (WIG) UAV with high lift-drag ratio, high payload and long endurance can be elected for priority consideration. This paper presents a WIG UAV design, analysis and fabrication. The WIG UAV has characteristics of high aspect ratio for lower speed and higher payload. UAV structure and aerodynamics analysis are studied to fulfill flight operation requirements under poor meteorological environment. Considering system performance, when WIG aircraft flies in ground effect, its longitudinal stability is weaker than in the air. Airfoils should be modified for a suitable design to smooth its sensitive longitudinal motion. For prompt system validation in the design phase, SolidWorks together with fluid field analysis is simulated using ANSYS/Fluent and XFLR to examine its aerodynamic effect around the wings. The simulation on this aircraft verifies the performance of ground effect. Several critical criteria in WIG design are settled in lift-drag ratio, coefficient of moment and longitudinal stability. WIG UAV is fabricated in remote control for flight tests. The prototype WIG UAV carries a series of flight tests to compare with the numerical simulation results. The proposed system design and test verifies that the high aspect ratio wing makes positive contribution to WIG aircraft in the ground effect zone. Some applications are recommended in water patrol and rescue.
