Abstract
A turbine engine airfoil element has an airfoil having: a pressure side and a suction side; and a plurality of spanwise passageway legs. The passageway legs include: a leading edge impingement cavity; and a plurality of main body feed passageway legs along a camber line. A wall separates the leading edge impingement cavity from a leading one of the main body feed passageway legs, the wall having a suction side section and a pressure side section joining at a junction, the junction forming a vertex of an angle of transverse cross-section of the wall; and a plurality of impingement feed holes through the wall. The plurality of impingement feed holes are larger thickness-wise than span-wise.
