Research On The Overall Design Of Solar UAV

Solared unmanned aerial vehicle(UAV)is key researched by scientific research institutions and universities in the world,because it is energy saving and environmental,much longer,low altitude flying and noiseless.It will be the key research direction in the future that a solared UAV capable of flying at a high altitude with the progress of science and technology,the increase of energy conversion rate and the increase of energy density and the appearance of various advanced composite materials.In the development process of the whole solar UAV,here must be a large aspect ratio wing to provide good gliding performance and the laying of large area solar cell.The large aspect ratio pneumatic layout is being used in many solar aircraft,but this layout will bring about a corresponding lack of stability and control.It will solve the problem of the high aspect ratio,through the special duck wing and fusion of wings and fuselage.In this paper,a new aerodynamic layout design is carried out on the basis of the design target,the layout of the fusion of the front duck wing and the wing body is put forward,complete the overall design,The simulation analysis is carried out by using CFD software,complete the overall layout of the aircraft,calculation and analysis of various flight performance and a three-dimensional model of the design.Finally,a special control scheme for the flight attitude stabilization control system is designed for the solar UAV...
