| Abstract: | In present paper the longitudinal and lateral aerodynamic characteristics of wing with low aspect ratio are calculated under considering the effect of vortex and vortex breackdown.On the basis of Purvis's lifting surface theory and suction simulation method developed by Polhamus,with reference to Lan's method the aerodynamic characteristics at high angle of attack are corrected.In the paper several wings with different plane shape are calculated.Calculation results are pretty close to the experiment results.The comparison shows that the present method can be used to calculation of aerodynamic characteristics of wings with low aspect ratio. |
