Abstract:
1. A sensor system for measuring a flow speed of a fluid stream relative to an object immersed in the fluid stream, the system comprising: a first obstructive body having a first forward facing surface and two lateral edges defining a first body span; a second obstructive body having a second forward facing surface and two lateral edges defining a second body span, the second obstructive body being positioned in tandem relative to the first obstructive body so that the first and second forward facing surfaces face the same direction and so that when the first forward facing surface is presented to an incoming fluid stream, the first obstructive body is between the incoming fluid flow and the second obstructive body; and a sensor array disposed on the second forward facing surface, the sensor array comprising at least one sensor element configured to measure changes in a fluid flow parameter over the sensor element, wherein the first and second obstructive bodies are attachable to the object so that the first forward face is presented to an incoming fluid stream when the object is immersed in the fluid stream.
