ANGLE OF ATTACK SENSOR VANE GEOMETRY

An angle of attack sensor includes a housing and a faceplate. A vane assembly extends through a central opening of the faceplate and includes a vane. The vane comprises a root, a tip, a leading edge, a trailing edge, a first lateral face, and a second lateral face. 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.
