1.2톤급 소형 위그선의 구조 개념설계

Abstract

This paper presents some results of structural design research for the 1.2 ton-class WIG craft, which is an experimental one(1/2 scale) for the verification of hydrodynamic and aerodynamic performances of the 20passenger-class WIG craft. The structural concept is approached by skin-stressed design method that skin carries major stresses. In this stage, global and local loads are defined for the WIG craft, and the process of structural sizing is performed. The general airframe design process is adopted for the structural design, Critical flight loads and the wave impact loads shall be considered for the final verification of this structural design process in near future. Definition of load conditions and fundamental analysis by FEM are used for whole skin sizing of the WIG craft. Further FEM analysis is under processing and its results will be considered in the critical deisgn stage later.
