摘要
Abstract
This study investigates the reduction of slamming load during the water entry of a seaplane under fully constrained fixed configurations.Four ventilation gaps are designed on the underside of the aircraft,and multiple load reduction strategies are tested by activating single or combined gaps.An experimental platform and data processing methodology are developed to systematically analyze the load mitigation effects of different ventilation strategies in a static water environment.The results demonstrate that under a ventilation flow rate of 116.34 L/min,individually activating the second or third ventilation gap reduces peak slamming load by 15.1%and 11.9%,respectively,compared to non-ventilated conditions,confirming the effectiveness of localized ventilation.Conversely,activating the first gap,the step-positioned gap,or multi-gap combinations increases load,highlighting the critical influence of gap positioning on air-cushion formation.关键词
