Abstract

The design process for the control surfaces and actuators of the long distance AUV DOLPHIN (UK "Autosub" project) is described. The main design criteria are low drag, reliability, robustness and energy-efficiency. The aerodynamic characteristics of four NACA foil sections and various stabiliser/moveable fin geometries are compared, in order to reach the final design, which incorporates a NACA 66-009 wing section with a partial span trailing edge flap. The actuator is located in a wing-tip pod, which also houses the sensors for oceanographic data logging. Preliminary analysis of wind tunnel tests on a full-scale model of the control surfaces confirms that the lift force required to achieve the specified manoeuvrability for DOLPHIN is easily generated. Measured drag data is lower than expected and this requires further analysis.
低阻力层流水下航行器的控制面和驱动器设计
介绍了长距离水下航行器DOLPHIN(英国“Autosub”项目)控制面和执行器的设计过程。主要设计标准是低阻力、可靠性、稳健性和节能。为了达到最终设计,比较了四种NACA翼型和各种尾翼/可动翼的气动特性,最终设计采用了带有部分跨尾缘襟翼的NACA 66-009翼型。执行器位于翼尖吊舱中,吊舱还装有用于海洋数据记录的传感器。在控制面全尺寸模型上进行的风洞试验初步分析证实,实现海豚指定机动性所需的升力很容易产生。实测阻力数据低于预期,这需要进一步分析。
