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.
What is the NACA 0012 airfoil used for?
NACA0012 airfoil was used for all configurations due to availability of experimental lift and drag data. Lift, drag and pressure coefficient were calculated with SST turbulence model at the Reynolds numbers of 6 × 10⁶ and were compared with experimental data to validate the simulation accuracy of numerical approaches.
Is NACA 0012 a thin airfoil?
This study aims at the recognition of the gap between the thin airfoil theory and the numerical experiment. The symmetrical airfoils of interest are NACA 0003, NACA 0006, NACA 0012, NACA 0024 and NACA 0030, while the cambered airfoils are NACA 1112, NACA 1212, NACA 1812, NACA 2412, NACA 4812, and NACA 23012.
Why NACA 0012 airfoil is said to be symmetric airfoil?
Explanation: The NACA 0012 airfoil indicates the symmetric airfoil, because an airfoil with no camber, that is with the camber line and chord line co-incident in an airfoil is called a symmetric airfoil. For the NACA 0012 airfoil is with a maximum thickness of 12%.
Is NACA 0012 symmetrical?
NACA 0012 airfoil is a symmetric airfoil so the thickness distribution is sufficient for the upper and lower surface definitions.
What do NACA 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.
How do you read NACA airfoil?
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 a chord in aerodynamics?
The distance between the leading and trailing edge of the wing, measured parallel to the normal airflow over the wing, is known as the chord. Most commercial transport airplanes have wings that are both tapered and swept with the result that the width of the wing changes along its entire length.
How airfoil increases its speed?
The airflow over the wing increases its speed causing a reduction in pressure; this generates a force (lift) perpendicular to the chord of the aerofoil. The amount of lift and drag generated by an aerofoil depends on its shape (camber), surface area, angle of attack, air density and speed through the air.
