NACA 1408 airfoil — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/naca-1408-airfoil/ (sheet CC BY 4.0; files Xem Studio Design License, https://xemstudio.com/license/) Basis: Computed from the NACA equations (Report 460 / Report 610, restated in NASA TM-4741) Catalog version: 2026-10-20 Overall (mm): length 100.0, width 20.0, height 8.0 - NACA 1408: 1 % camber at 40 % chord, 8 % thick. - NACA 4-digit: first digit = maximum camber in % of chord, second = its position in tenths of chord, last two = maximum thickness in % of chord (NACA Report 460). - Ordinates are in % of chord from the leading edge, computed from the published equations with the closed-trailing-edge thickness coefficient (−0.1036, as in NASA TM-4741). The original reports use an open trailing edge (−0.1015); the difference is under 0.03 % of chord near the trailing edge. - The file is a 100 mm chord section, 20 mm deep: scale it uniformly to your chord, or import the STEP and sweep or loft it into a wing. Thickness scales with chord; the shape is the same at any size. x (% chord) upper x upper y lower x lower y 0 0.000 0.000 0.000 0.000 1.25 1.189 1.323 1.311 -1.200 2.5 2.418 1.862 2.582 -1.620 5 4.896 2.602 5.104 -2.133 7.5 7.386 3.137 7.614 -2.458 10 9.883 3.557 10.117 -2.682 15 14.889 4.171 15.111 -2.952 20 19.904 4.574 20.096 -3.074 25 24.926 4.819 25.074 -3.100 30 29.950 4.938 30.050 -3.063 40 40.000 4.867 40.000 -2.867 50 50.020 4.496 49.980 -2.552 60 60.034 3.920 59.966 -2.142 70 70.040 3.172 69.960 -1.672 80 80.038 2.269 79.962 -1.158 90 90.025 1.215 89.975 -0.604 95 95.014 0.629 94.986 -0.309 100 100.000 -0.000 100.000 0.000 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - NACA (NASA Technical Reports Server): Report 460: The characteristics of 78 related airfoil sections from tests in the variable-density wind tunnel (Jacobs, Ward, Pinkerton, 1933) — web — Publisher's page; dimensions are facts — https://ntrs.nasa.gov/citations/19930091108 - NASA: TM-4741: Computer program to obtain ordinates for NACA airfoils (Ladson, Brooks, Hill, Sproles, 1996) — web — Publisher's page; dimensions are facts — https://www.pdas.com/refs/tm4741.pdf Free files (Xem Studio Design License, Xem Studio; STEP + STL, 1 parts): https://xemstudio.com/files/hardware/naca-1408-airfoil/index.json API: https://xemstudio.com/api/geometry?object=naca-1408-airfoil
