Abstract


With the development of the economy and national defense construction , high-altitude , long-endurance UAV is becoming more and more important . China 's special national conditions of high-altitude, long- endurance unmanned aerial vehicle made ??various technical requirements , which requires serialization design of the UAV . Aerodynamic characteristics of the high - altitude , long-endurance unmanned aerial vehicle series , remotely coupled canard aerodynamic configuration . The focus of this research is the canard high-altitude long- endurance UAV series of conceptual design aerodynamic optimization problem . In the high-altitude, long- endurance unmanned aerial vehicle the EXCEL overall parameter calculation and optimization program based on conceptual design , through joint optimization software iSIGHT and CAD software CATIA , improved optimization capabilities of the original program , three-dimensional sketches automatically draw function , which developed out the visualization concept design and optimization of the system for UAV design phase . Series of high-altitude long-endurance UAV concept design examples to prove the superiority of the conceptual design and optimization system visualization unmanned aerial vehicle based on EXCEL . Aerodynamic optimization problem , we draw on multidisciplinary optimization technology in multi-level optimization method , suitable for high - altitude , long-endurance unmanned aerial vehicle series two aerodynamic optimization framework . In order to reduce the amount of computation , the aerodynamic optimization using the agency model . High-altitude long -endurance UAV series of aerodynamic optimization examples show that both the aerodynamic performance of the aircraft aerodynamic optimization method based on the agent model two , greatly reducing the total induced drag coefficient of the UAV series . In order to further analyze the aerodynamic performance of the optimization program , the end of this article more accurate aerodynamic numerical the calculation software MGAERO conduct high-altitude long-endurance UAV series of pneumatic analysis . To display the results visually using OMIN3D software post-processing .
