摘要

波浪驱动飞行器是一种以捕获波浪能为动力的水面飞行器,在部分海域执行任务时需要面对恶劣的海况。然而,波浪驱动飞行器通常体积较小,在大海况下的航海性能和速度一般较差。波浪驱动车辆通常配备刚性连接的水翼来捕捉波浪能,从而为波浪驱动车辆提供动力,并增强其航海性能。针对波浪驱动车辆在高海况下的长期生存和运行要求,本文研究了高海况下水翼对波浪驱动车辆自推进性能的影响。在波浪推进器上安装刚性连接水翼后,改变水翼的结构参数,基于 CFD 方法对波浪推进器在 0-90° 遇浪角下的运动学和动力学响应进行了数值模拟。分析了水下翼深、水翼间距和水翼跨度长度对波浪驱动飞行器自推进性能的影响。在此基础上,对刚性连接水翼的结构参数进行了优化,从而提高了波浪驱动飞行器在高海况下的适航性和快速性。

Analysis and optimization of self-propelled performance of wave-driven vehicle hydrofoil under high sea-level condition

The wave-driven vehicle is a surface vehicle powered by capturing wave energy, which is required to face harsh sea conditions when performing tasks in parts of the ocean. However, wave-driven vehicles are usually small in size, and their seakeeping and speed are generally poor in high sea conditions. Wave driven vehicles are usually equipped with rigid connected hydrofoils to capture wave energy, which can provide power for wave driven vehicles and enhance seakeeping. Aiming at the long-term survival and operation requirements of wave-driven vehicle under high sea conditions, this paper studies the effect of high sea conditions launching wing on the self- propelled performance of wave-driven vehicle. After installing rigid connected hydrofoils on wave-driven vehicles, the structural parameters of the hydrofoils are changed, and the kinematic and dynamic responses of wave-driven vehicles at 0–90 ° wave encounter Angle are numerically simulated based on CFD method. The effects of underwater wing depth, hydrofoil spacing and hydrofoil span length on the self- propelled performance of wave-driven vehicles are analyzed. Based on this, the structural parameters of rigidly connected hydrofoils are optimized, which improves the seakeeping and rapidity of wave-driven vehicles in high sea conditions.
