How do you read a 5 digit airfoil NACA?

NACA Five-Digit Series: The first digit, when multiplied by 3/2, yields the design lift coefficient (cl) in tenths. The next two digits, when divided by 2, give the position of the maximum camber (p) in tenths of chord. The final two digits again indicate the maximum thickness (t) in percentage of chord.

What does the 4 digit numbers mean in NACA airfoil?

The NACA four-digit airfoils are represented by NACAxxxx. The last two digits represents the airfoil maximum thickness. The first digit represents the the maximum mean camber. The second digit represents the location of the maximum camber.

What do airfoil numbers mean?

NACA airfoils map a four digit code to an airfoil shape. For example, a ‘2412’ airfoil is parsed to mean: The leading ‘2’ indicates maximum camber is 2% of chord length. The ‘4’ indicates maximum camber is at 40% of the chord length.

What does NACA stand for?

The Neighborhood Assistance Corporation of America (“NACA”) is a non-profit, community advocacy and homeownership organization. NACA’s primary goal is to build strong, healthy neighborhoods in urban and rural areas nationwide through affordable homeownership.

What is airfoil thickness?

The thickness of an airfoil varies along the chord. It may be measured in either of two ways: Thickness measured perpendicular to the camber line.

What is airfoil theory?

Abstract. Thin airfoil theory is a straightforward hypothesis of airfoils that relates angle of attack to lift for an incompressible and inviscid flow past an airfoil.

What is NACA classify NACA airfoils?

The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word “NACA”.

What is the camber of a NACA airfoil?

For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the leading edge with a maximum thickness of 12% of the chord. The NACA 0015 airfoil is symmetrical, the 00 indicating that it has no camber. The 15 indicates that the airfoil has a 15% thickness to chord length ratio: it is 15% as thick as it is long.

What is cambered airfoil with example?

For example, a NACA 2412 airfoil uses a 2% camber (first digit) 40% (second digit) along the chord of a 0012 symmetrical airfoil having a thickness 12% (digits 3 and 4) of the chord. For this cambered airfoil, because the thickness needs to be applied perpendicular to the camber line, the coordinates

What is a NACA 4 digit airfoil?

NACA 4 digit airfoil specification This NACA airfoil series is controlled by 4 digits e.g. NACA 2412, which designate the camber, position of the maximum camber and thickness. If an airfoil number is

What is the maximum camber of a 2412 airfoil?

For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the leading edge with a maximum thickness of 12% of the chord. Four-digit series airfoils by default have maximum thickness at 30% of the chord (0.3 chords) from the leading edge.
