摘要
The present invention relates to a helicopter sizing analysis module for optimizing a shape by repeatedly designing a harmful drag of a modified armed helicopter to be minimized while determining a size of a body through trend analysis of a currently used helicopter and satisfying requirements of a requester; An aerodynamic characteristic prediction module for predicting the basic body drag of the modified armed helicopter in a predetermined manner and comparing the drag characteristics of the armed / unarmed shape according to the change in angle of attack; There is provided an aerodynamic characteristic and performance prediction device for a light armored helicopter according to an external weapon including a performance analysis module for analyzing a change in a major performance index according to a change in weight and a drag strength area of the retrofitted armed helicopter. The present invention analyzes and predicts changes in aerodynamic characteristics and major performance indices according to the shape of the external arming and main foreign objects of the small arming helicopter as described above, It is possible to precisely predict the range of modification and to select the base helicopter to be modified so as to meet the performance required by the buyer, thereby maximizing the efficiency of the modification of the armed helicopter.
