An inlet guide vane provides improved, smooth airflow and avoids separation of flow even at high incidence angles. The inlet guide vane includes a strut having opposite side surfaces that are continuously curved to provide a controlled velocity distribution at the trailing edge of the strut. The inlet guide vane further includes a flap having a leading edge aligned behind the trailing edge of the strut. Generally, the strut and the flap are designed together so that low momentum air in the gap between the strut and the flap will be energized and entraine...
What is claimed is: 1. An inlet guide vane comprising: a fixed airfoil having a leading edge and a trailing edge; and a variable incidence airfoil having a leading edge spaced aft of the trailing edge of the fixed airfoil by a gap, the variable incidence airfoil being pivotable about an axis near the leading edge of the variable incidence airfoil, wherein the leading edge of the variable incidence airfoil remains masked behind the trailing edge of the fixed airfoil throughout a full variable range of incidence of the variable incidence airfoil and where...
