Abstract

Gas turbine engine (10) nozzle and associated airfoil (123) designs are disclosed. An airfoil (123) of an engine nozzle segment (140, 800) includes: a convex panel (920, 1120); a concave panel (1020); an outer band (930, 1030, 1130); and an inner band (940, 1040, 1140). The convex panel (920, 1120) includes a plurality of metering holes (910, 1010, 1110), the airfoil (123) characterized by the following equation, in which a convex panel (920, 1120) metering hole area (1230) (CVXA (860, 980)), inner band (940, 1040, 1140) radius (IBR), and loading area (840, 1090) (LA) are related as follows: EQ1=CVXAm20.000005m2+0.000005IBRmπmLAm20.00001m2, wherein 0.0000001 meters squared (m²) ≤ CVXA ≤ 0.000004 m², 0.213 m ≤ IBR ≤ 0.221 m, 0.0000147 m² ≤ LA ≤ 0.0000153 m², and 4.835 ≤ Equation 1 ≤ 281.150.
