水陆两栖飞机模型水池波浪试验研究

Study of Scaled Model Tank Tests in Waves of an Amphibian

在拖曳水池中开展了水陆两栖飞机模型规则波匀速试验和匀加速试验。试验结果表明,在匀速试验中,随着波长的增大,试验模型的纵倾角和升沉响应曲线具有1个共振峰值,而垂向加速度响应具有2个共振峰值;在匀加速试验中,速度变化对纵倾角和升沉响应幅值影响较小,垂向加速度响应在低速时较小,而在高速时急剧增大。

The tank regular wave test of an amphibian model was conducted, the test velocity was set as constant and accelerated equally. The test results turned out to be that, the trim angle and heaving response bear one resonance value and the vertical acceleration response bears two resonance value when the model slide with constant velocity. When the model accelerates equally, the velocity change has a little influence on trim and heaving amplitude value, while the vertical acceleration response gently at low speed and violently at high speed.
