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 inner band (940, 1040, 1140) having an inner band (940, 1040, 1140) flow area (IBFA) and including a plurality of metering holes (910, 1010, 1110), the airfoil (123) characterized by the following equation, in which the IBFA, inner band (940, 1040, 1140) radius (IBR), and loading area (840, 1090) (LA) are related as follows: EQ 1 = IBR m πm * LA m 2 0.00001 m 2 * IBFA m 2 0.000001 m 2 2 <img class="EMIRef" id="07eadbc3-2700-4c32-9450-2d87ecd618c5-ia01" /> , wherein 0.0000002 meters squared (m<2>) ≤ IBFA ≤ 0.0000019 m<2>, 0.213 m ≤ IBR ≤ 0.221 m, 0.0000147 m<2> ≤ LA ≤ 0.0000153 m<2>, and 0.006 ≤ Equation 1 ≤ 0.393.
