KLA-100 공력 하중 구조 FEM 하중 전환

The first step of the structural analyses is the (structural) load analysis which is the work of the transformation of external forces such as aerodynamic forces to structural loads. When the 3-D FEM is not fully developed, the external loads are transformed to the structural internal loads such as shear forces and bending moments. But, when the 3-D FEM is used, the work to transform the aerodynamic loads to external FEM load applied to the structures becomes very important. The methodology and the results of the load analysis applied the KLA-100, the light airplane for sports, are presented in this paper, This method is applied to the wing, horizontal tail, vertical tail, control surfaces and the fuselage of KLA-100.
