What does NACA 2415 mean?
NACA 2415 airfoil has a maximum thickness of 15% with a camber of 2% located 40% back from. the airfoil leading edge (or 0.4c). Utilizing these m, p, and t values, we can compute the coordinates. for an entire airfoil using the following relationships: 1.
What is the thickness in NACA 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.
Is NACA 2415 symmetrical?
The 2415-3 airfoil has the lowest lift for all angles of attack and its behavior is close to a symmetric airfoil (almost zero lift at zero angle of attack). The curve is linear until 14 degrees of AOA where an abrupt decrease begins which corresponds to the stall point. Fig.
What is the thickness in NACA 747a315 airfoil?
Max thickness 15% at 40.2% chord.
What is the best airfoil design?
The most efficient airfoil for producing the greatest lift is one that has a concave or “scooped out” lower surface. As a fixed design, this type of airfoil sacrifices too much speed while producing lift and is not suitable for high-speed flight.
What is reflexed camber airfoil?
An airfoil where the camber line curves back up near the trailing edge is called a reflexed camber airfoil. Such an airfoil is useful in certain situations, such as with tailless aircraft, because the moment about the aerodynamic center of the airfoil can be 0.
What is the NACA 0012 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.
What type of airfoil is a NACA 0012 airfoil?
NACA0012 airfoil is a symmetrical low lift airfoil with maximum thickness being 12% of the chord located at 30% of the chord length. The airfoil shape is shown in figure.
Which aircraft uses NACA 23012?
They include NACA 23012 used in STOL aircraft Helio 295 Super Courier (U-10), US35b used in Piper Cub and the airfoil of Fieseler Fi 156 Storch-perhaps, the most successful STOL aircraft. In fact, Syamsuar, Djatmiko, Erwandi, Mujahid and Subchan (2016) used NACA 23012 in their investigations of a WIG craft.
