| Abstract: | The present paper makes investigation based on ref.1] for analytical predicting the aerodynamic characteristics of arbitrary strake-wing planforms with sharp-edge in subsonic flow. General expressions have been derived for predicting aerodynamic characteristics of strake-wing with curved leading-edge and spanwise lift distribution of strake-wing with pointed tip. Potential flow lift constant in the expression is obtained by the vortex-lattice method.Results of analytical prediction for several examples of strake-wing are compared with experimental data which shows that it is accurate and fast in calculation. This method is applicable to aircraft design and characteristics analysis. |
