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. The 15 indicates that the airfoil has a 15% thickness to chord length ratio: it is 15% as thick as it is long.
The lift coefficient C L is defined by [2] [3] = =, where is the lift force, is the relevant surface area and is the fluid dynamic pressure, in turn linked to the fluid density, and to the flow speed.
Lift and drag are the two components of the total aerodynamic force acting on an aerofoil or aircraft.. In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air.
Schemes have been devised to define airfoils – an example is the NACA system. Various airfoil generation systems are also used. An example of a general purpose airfoil that finds wide application, and pre–dates the NACA system, is the Clark-Y. Today, airfoils can be designed for specific functions by the use of computer programs.
The Cessna A-37 Dragonfly, or Super Tweet, is a light attack aircraft designed and produced by the American aircraft manufacturer Cessna.. It was developed during the Vietnam War in response to military interest in new counter-insurgency (COIN) aircraft to replace aging types such as the Douglas A-1 Skyraider.
The airfoil employed is a NACA 2412, the same as used on the later Cessna 150, 172 and 182. [3] [8] The 190/195 fuselage is large in comparison to other Cessna models because the 42" diameter radial engine had to be accommodated in the nose.
Lola Blankets are expensive — there's no denying that. But they're also ridiculously warm. If you live in an extra-cold region and have the disposable budget, this blanket is a must-own.
