What do NACA airfoil numbers mean?

The NACA four-digit wing sections define the profile by: First digit describing maximum camber as percentage of the chord. Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. Last two digits describing maximum thickness of the airfoil as percent of the chord.

What is NACA 4 digit series airfoil?

National Advisory Committee for Aeronautics airfoils. During the late 1920s and into the 1930s, the NACA developed a series of thoroughly tested airfoils and devised a numerical designation for each airfoil — a four digit number that represented the airfoil section’s critical geometric properties.

What is the thickness in NACA 2412 airfoil mean?

The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). 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.

Which NACA airfoil is best?

There is no single airfoil that will always create more lift than another airfoil. The amount of lift that an airfoil creates has to do with the angle of attack, speed, and other flight conditions. Different airfoils work well in different conditions. A very common NACA airfoil is the NACA 4412.

How do you read NACA 5 Series?

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 NACA 0012 mean?

NACA 0012 mean that there is no camber i.e. zero camber is present, and it has the maximum thickness of the airfoil at 12\% of the chord from the leading edge.

How do you read a 5 digit airfoil NACA?

What is NACA 6 Series?

The NACA 6-series and 6A-series airfoils are defined by means of conformal transformations. These relate the flow over an airfoil to that of a near-circle and that to a circle. These functions are multiplied by a scale factor to produce airfoils of various thickness to chord ratios.

What NACA means?

The Neighborhood Assistance Corporation of America (“NACA”) is a non-profit, community advocacy and homeownership organization.

What is the NACA 0012 airfoil used for?

NACA 0012 airfoil is chosen to model and simulate processes of computational fluid dynamics. Analyzes to obtain velocity and pressure distribution on the wing surface were performed using ANSYS Fluent software. Also, the drag and lift coefficients were calculated according to variable relative velocities.
