Application Of Boundary Element Method To Predicting The Aerodynamics Coefficient Of Aircraft With Arbitrary Shape Cross Sections

摘要：

　　This paper introduces an application of boundary element method for predicting the aerodynamics coefficient of aircraft with arbitrary shape cross sections.Aerodynamics coefficient of noncircular body is evaluated based on this method.Comparing with the method adopted by McDonnell Douglas Astronautics Company,a more accurate prediction is achieved based on the Boundary Element method.Combining this method with Component Build-Up method,the aerodynamics coefficient of aircraft is calculated,which can satisfy the aerodynamics design of concept stage.A surrogate model is developed based on design of experiment and radial basis function,which can improve the efficient of this method significantly.
