1. An angle of attack sensor comprising:
a housing having an open end and a closed end;
a faceplate positioned on the open end of the housing, the faceplate comprising:
a periphery at an outer edge of the faceplate;
a central opening; and
an exterior surface extending from the periphery to the central opening;
a vane assembly extending through the central opening of the faceplate, the vane assembly comprising:
a vane hub positioned in the central opening of the faceplate; and
a vane connected to the vane hub, the vane comprising:
a root connected to the vane hub;
a tip opposite the root;
a leading edge extending from the root to the tip;
a trailing edge extending from the root to the tip opposite the leading edge;
a first lateral face extending from the leading edge to the trailing edge; and
a second lateral face opposite the first lateral face and extending from the leading edge to the trailing edge;
wherein the first lateral face and the second lateral face are symmetric about a chord of the vane and each have a forward section with an outer surface profile that is nonlinear and geometrically convex from the leading edge to a transition point at a tangent to the widest point of the geometrically convex outer surface profile and each have an aft section with an outer surface profile that extends out to form a diverging wedge shape from the transition point to the trailing edge.
