Effects of Compressibility on the Maximum Lift Characteristics and Spanwise Load Distribution of a Foot-Span Fighter-Type Wing of NACA Series Airfoil. For example, the NACA profile describes an airfoil with design lift coefficient of ( × 2), the point of maximum camber located at 15% chord (5 × 3). The NACA is symmetrical airfoil with no camber and 12% thickness to chord length ratio. Acoustic measurements were conducted in an anechoic wind tunnel.

The simplest asymmetric foils are the NACA 4-digit series foils, which use the same formula as that used to generate the 00xx symmetric foils, but with the line of mean camber bent. The formula used to calculate the mean camber line is [4].

The NACA five-digit series describes more complex airfoil shapes. For example, the NACA profile describes an airfoil with design lift coefficient of 0. The camber line is defined as [10]. Camber lines such as makes the negative trailing edge camber of the series profile to be positively cambered. This results in a theoretical pitching moment of 0.

Four- and five-digit series airfoils can be modified with a two-digit code preceded by a hyphen in the following sequence:. In addition, for a more precise description of the airfoil all numbers can be presented as decimals. A new approach to airfoil design pioneered in the s, in which the airfoil shape was mathematically derived from the desired lift characteristics.

Prior to this, airfoil shapes were first created and then had their characteristics measured in a wind tunnel. The 1-series airfoils are described by five digits in the following sequence:. An improvement over 1-series airfoils with emphasis on maximizing laminar flow. The airfoil is described using six digits in the following sequence:. Further advancement in maximizing laminar flow achieved by separately identifying the low-pressure zones on upper and lower surfaces of the airfoil.

The airfoil is described by seven digits in the following sequence:. Supercritical airfoils designed to independently maximize laminar flow above and below the wing. The numbering is identical to the 7-series airfoils except that the sequence begins with an "8" to identify the series. From Wikipedia, the free encyclopedia. Wing shape. Retrieved 27 July Jacobs, K.

Dj volume Click University. From Wikipedia, the free encyclopedia. Supercritical airfoils designed to independently maximize laminar flow above and below the wing. Retrieved 27 July During the late s and into the s, 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.

Naca 230 12 The numbering is identical to the 7-series airfoils except that the sequence begins with an "8" to identify the series. The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Here, the aerodynamic center is behind the quarter-chord point, and becomes progressively farther behind as the airfoil thickness is increased. Download as PDF Printable strip pokemon.

If you have airfoil designations for any of these aircraft, please e-mail me at: dave lednicer. A note: this list has grown to the point where it is quite large. For this reason, it takes a while to load. I apologize for the inconvenience but assure you that the wait is worth it!

On designations: many of the airfoils listed here have "mod" at the end of their designation. Typically, this means that either the camber line has been modified, the leading edge contour has been modified or that the trailing edge thickness has been changed. Some common airfoil name prefixes and their designers are:. Peter Lissaman of AeroVironment Inc. MAC - Airfoils designed at Mitsubishi.

During the s, the designer was Tsutomu Fujino. TH - Dr. Jane's All The World's Aircraft has been a good source of this information, but in many cases particularly military aircraft it doesn't list this information. To answer this perennial question, the following list has been created. Besides conventionally configured aircraft, canard configured aircraft, tandem wing aircraft, three-surface aircraft, helicopters, tilt rotors and autogyros are addressed.
