在海洋调查研究中,“双旋桨矢量测量海流计”技术先进。其主要优点是:传感器具有良好的余弦响应特性;传感器直接感应流的两个正交分量;测量结果便于计算机进行各种数据处理。 一、传感器的实验室试验 1.旋桨的“风洞”试验 传感器重要的特殊的性能是对流迎角的余弦响应。最初的试验是在自行建造的简易“风
In the marine investigation and research, “dual-propeller vector measurement flow meter” advanced technology. The main advantages are: the sensor has a good cosine response characteristics; the sensor directly senses the two orthogonal components of the flow; the measurement results facilitate the computer to perform various data processing. First, the sensor laboratory test 1 propeller “wind tunnel” test sensor The important special performance is the convection angle of attack of the cosine response. The first test was a simple “wind” built on its own
