摘要

摘要: 根据水上飞机起飞滑行阶段特殊的多介质环境,参考滑行艇水面滑行阶段的阻力特性分析方法,提出一种考虑气动布局影响的估算船身式水上飞机中高速静水滑行阻力的半理论半经验公式;用此公式计算得到某船身式水上飞机中高速滑行阶段的水动阻力及俯仰角随体积弗劳德数变化曲线,并分析水动阻力及俯仰角变化的原因;根据得到的水动阻力及俯仰角,计算某船身式水上飞机起飞滑跑距离,计算结果与试验结果一致,间接验证了所提出阻力计算公式的有效性,同时也为计算船身式水上飞机起飞滑跑距离提供一种思路.

Abstract: Considering the unique multimedia condition during take-off process of a flying boat and referring to the method of studying the resistance performance of a planning boat in the sliding process, a formula, to evaluate the resistance of a flying boat at medium and high speed in calm water, was proposed. The formula combines theoretical analysis and empirical correction and also includes the effect of aerodynamic distribution. With this formula, graphs illustrating hydrodynamic resistance and pitch angle varying with the volume Froude number were obtained and the reasons for the varying were analyzed. Take-off running distance was calculated with the hydrodynamic resistance and pitch angle that calculated from the formula. As the calculated take-off running distance is in consistent with experimental results, the validation of the formula was verified indirectly. And a method to calculate the take-off running distance of a flying boat was also proposed at the same time.
