Abstract

Gas turbine engine (10) nozzle and associated airfoil (123) designs are disclosed. An example airfoil (123) includes: a concave panel (1020); a convex panel (920, 1120); a baffle; an outer band (930, 1030, 1130); and an inner band (940, 1040, 1140), the concave panel (1020) including a plurality of metering holes (910, 1010, 1110), the airfoil (123) characterized by the following equation, in which a concave panel (1020) metering hole area (1230) (CCVA (830, 1080)), baffle area (BA), inner band (940, 1040, 1140) radius (IBR), and loading area (840, 1090) (LA) are related as follows: EQ 1 = CCVA m 2 − 0.0000152 m 2 0.0000152 m 2 − 3 + BA m 2 0.001 m 2 LA m 2 0.00001 m 2 * IBR m 20 m , <img class="EMIRef" id="1219ed77-300e-4dab-b90a-d7bf0a7ea93a-ia01" /> wherein 0.00005 meters squared (m<2>) ≤ BA ≤ 0.0002 m<2>, 0.000005 m<2> ≤ CCVA ≤ 0.000015 m<2>, 0.213 m ≤ IBR ≤ 0.221 m, 0.0000147 m<2> ≤ LA ≤ 0.0000153 m<2>, and 4850.690 ≤ Equation 1 ≤ -0.03.
