Abstract

Gas turbine engine (10) nozzle and associated airfoil (123) designs are disclosed. An example airfoil (123) includes: a convex panel (920, 1120); a concave panel (1020); an outer band (930, 1030, 1130); and an inner band (940, 1040, 1140), the concave panel (1020) having an area of maximum curvature (MC) including a plurality of metering holes (910, 1010, 1110), the airfoil (123) characterized by the following equation, in which a MC metering hole area (1230) (MCA (870, 1180)), inner band (940, 1040, 1140) radius (IBR), and loading area (840, 1090) (LA) are related as follows: EQ 1 = IBR m 1 m LA m 2 0.00001 m 2 ∗ MCA 870 1180 m 2 0.000005 m 2 2 , <img class="EMIRef" id="34a8ea57-9ab3-45ca-be72-92fda08b5d6b-ia01" /> wherein 1.720x10<-6> meters squared (m<2>) ≤ MCA ≤ 3.000x10<-6> m<2>, 0.213 m ≤ IBR ≤ 0.221 m, 0.0000147 m<2> ≤ LA ≤ 0.0000153 m<2>, and 0.351 ≤ Equation 1 ≤ 1.644.
