| Abstract: | This paper, by applying velocity potential theory and small disturbance slender body theory, has established the theory base for predicting the aerodynamic normal force of bodies with arbitrary shape cross section and formed the method of engineering approximation. This method, by calculating the coefficient of cross section shape and modifying the aerodynamic normal force of bodies with circular shape cross section, can conveniently predict the aerodynamic characteristic of arbitrary shape cross section bodies. Results obtained by this method are compared with experimental data and the accuracy of this method is founded to be very good within the constraints of slender body theory. |
