WIG선의 이수 상태 추정 모델

Abstract

WIGs need most of their engine power during take-off state. Usually sizes and weights of WIGs' engines are selected according to the estimated maximum power during take-off. Therefore, it is very important for a WIG designer to estimate required power and state change during take-off. In this paper, a mathematical model for the estimation of WIGs' take-off state at the early design stage is suggested. The model was built based on a steady planing state model of a planing boat. Through numerical calculations on various take-off states, it was found that the suggested model could give reasonable estimation of required power and state change during take-off.
