Abstract
The present invention relates to a air data sensing probe that has a cylindrical barrel joined to a contoured strut section. The strut has leading and trailing edges formed along curved paths, and supports the cylindrical barrel at a position spaced from a mounting surface and facing upstream of relative air movement. The strut has a rounded leading edge, and is generally ogival-shaped in cross-section. There is a blended, relatively quickly-changing transition section to blend the trailing end of the cylindrical barrel into the ogival-shaped strut section so that the probe has reduced weight of the strut and drag, and through reduction of the cross-sectional area and rounding the strut leading edge, has enhanced anti-icing performance.
