Abstract: A flow speed sensor arrangement is provided for measuring a flow speed of a fluid stream relative to an object. The arrangement comprises a first obstructive body having a first forward facing surface and two lateral edges and a second obstructive body having a second forward facing surface. The second obstructive body is 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. A sensor array is disposed on the second forward facing surface. 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.

Abstract: A method is provided for calculating flow performance characteristics of a body immersed in a fluid under a set of fluid flow conditions. The method comprises providing a geometrical description of a surface of the body and determining the set of fluid flow conditions. The set of fluid flow conditions includes a combination selected from the combination set consisting of angle of attack and leading edge stagnation point location, angle of attack and flow separation point location, and leading edge stagnation point location and flow separation point location. The method further comprises calculating a velocity flow field for the body using a critical point potential flow methodology and calculating flow performance characteristics.

Abstract: A method is provided for determining an aerodynamic coefficient for a body immersed in a fluid under a set of fluid flow conditions. The method comprises obtaining surface flow parameter data for a plurality of locations on the body. These locations include body surface points straddling an area of the body surface where a leading edge stagnation point (LESP) is expected to be located. The method further comprises determining the LESP location and an angle of attack of the body with respect to freestream conditions of the fluid using the flow parameter data. The method also comprises determining the aerodynamic coefficient from the LESP location and the angle of attack using an aerodynamic model.
