摘要
水下滑翔机以其低功耗、低成本和低噪声等优势在海洋科研、环境监测、资源探测和军事侦察等领域具有广阔的应用前景,水下滑翔机主要用于海洋环境长时间、大范围的实时监测,因此要求其具有优良的水动力性能。文章利用Javafoil程序总结了水下滑翔机水平固定平板翼升阻比与翼型参数之间的特征关系,并基于该关系在综合考虑升阻比和俯仰力矩两方面因素后确定了水下滑翔机水平固定平板翼的参数。此外为改善水下滑翔机稳定性,分析和设计了柔性机翼,对水下滑翔机水平固定翼的设计具有一定指导和借鉴意义。
Underwater glider has broad application prospect in marine scientific research, environmental monitoring, resource exploration and military reconnaissance etc since it consumpts less energy,costs less and has less noise. Underwater glider is mainly used in real - time monitoring the marine environment, so it is required a good hydrodynamic performance. In this paper, the Javafoil programme is used to analyse the relationship between lift to drag ratio and aerofoil parameters of horizontal fixed wing of underwater glider. Based an that, taking lift to drag ratio and pitching moment into consideration, parameters of wing are decided. In addition, to improve the stability of the underwater glider, the flexible wing is analyzed and designed, providing guidance and reference for the design of the horizontal fixed wing of the underwater glider.
