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
