Abstract

The simulation results of a small racing boat racing in steady wind and encountering waves are investigated by Nakato & Ha. The simulation of the race running is realized by referring the measured data of boats and the motions are described by a set of equations of motion in six degree of freedom as generals used in the aerodynamics. In this report, Nakato & Ha's motion equations are modified by equipping the flaps to generate the lift. The flaps of the racing boat could restrain considerably the boat from capsizing caused by superposed external disturbances, wind and encountering waves.

Nakato & Ha[2]는 정상풍(steady wind) 및 파랑충격의 외력을 받는 소형경주정의 운동 및 전복에 관한 시뮬레이션 연구 결과를 발표하였다. 경주정의 시뮬레이션은 실험 데이터를 이용하고 외력을 고려한 항공역학에서 일반적으로 사용되는 6자유도 운동방정식을 풀어서 수행하였다. 본 논문에서는 선미플랩을 부착하여 양력을 발생토록하여 Nakato & Ha의 운동 방정식을 수정하였다. 플랩에 의한 경주정의 제어는 바람과 파도의 중첩된 외부교란에 의한 전복현상을 상당히 억제시킬 수 있음을 알았다.
