对一种无人水面航行器进行了自由运行机动试验，以研究为航行器提供动力的水射流入口横流的影响。进行了绕圈、直线和转弯动作。开发了一个数据采集系统，以同时测量由水射流产生的推力和船舶的位置、速度和航向。从速度和航向测量中估计了水射流入口的纵向和横向流动。研究发现，横流的存在与水射流处推力的下降有关。
Free running manoeuvring trials of an unmanned surface vehicle were performed to investigate the effects of cross flow at the inlet of the waterjets powering the vehicle. Circle, straight-line and turning manoeuvres were performed. A data acquisition system was developed to simultaneously measure the thrust developed by the waterjet and the vessel’s position, speed, and heading. The longitudinal and cross flow at the inlet of the waterjet was estimated from the speed and heading measurements. It was found that the presence of cross flow correlates with a drop in the thrust developed at the waterjet.
