What airfoil do commercial planes use?

What airfoil do commercial planes use?

Modern commercial aircraft are monoplane; the wings are fixed, full cantilever type. Elimination of wires and struts reduces air drag, thus the speed of the modern aircraft is almost double compared to earlier aircraft with the same engine.

Which aircraft uses the NACA 2412?

Problem 3 (25 points) The NACA 2412 Airfoil has been our model airfoil for high wing, single engine Cessna aircraft. It is a relatively thin and efficient wing cross-section. Consider the NACA 2412 airfoil at an angle of attack of 6°, and a Re = 8.9 x 106.

Which aircraft uses NACA 0012?

II. As you know NACA0012 is symmetrical airfoil and used in few of aircrafts and it is used in tip of the wing/ flaps of the wing . Modified NACA0012 is also used in some aircrafts. Some of the helicopters are having this airfoils.

What aircraft uses NACA 4412?

The NACA 4412 has been used in sports plane. The example includes AAI-AA2 mamba aircraft, aeronca series aircraft like aeronca 65-tac defender, aeronca 11ac chief etc while the S1223 is an airfoil used in heavy lift cargo planes [2].

What airfoil does the Cessna 172 use?

The wing has the same NACA 2412 airfoil that Cessna’s been using since production of its 170, and the plane continues to use the same flat-plate ailerons that 172s and 152s have always been known for, making it a steady handler, if not exactly an exciting one.

What is an airplane airfoil?

An airplane’s wing has a special shape called an airfoil. The airfoil is shaped so that the air traveling over the top of the wing travels farther and faster than the air traveling below the wing. Thus, the faster moving air above the wing exerts less pressure than the slower moving air below the wing.

What type of airfoil is NACA 2412?

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.

Is NACA 2412 Good?

In the same way that an airplane wing gets more lift as it increases its angle of attack, the NACA 2412 airfoil receives drastically more pressure loss as the angle of attack increases, producing a strong lifting force.

What NACA 2412?

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.
