LIFT‚ DRAG AND MOMENT OF A NACA 0015 AIRFOIL by Steven D. Miller DEPARTMENT OF AEROSPACE ENGINEERING THE OHIO STATE UNIVERSITY 28 MAYi 2008 ABSTRACT A NACA 0015 symmetrical airfoil with a 15% thickness to chord ratio was analyzed to determine the lift‚ drag and moment coefficients. A 2D airfoil was placed in a low speed wind tunnel with pressure taps along its surface and a pitot probe downstream to measure the flow characteristics. The wind tunnel was operated at a nominal 17 m/s during

The Airfoil & Theories of Lift Airfoil Definition: Have you noticed the curved shape of a bird ’s wing? An airplane ’s wing is curved also. A wing is designed for flight. It has a special shape called an airfoil. The airfoil shape provides a lifting force when air flows around it. Airfoil shapes can be found on wings‚ fans and propellers. Importance: An airplane’s airfoil plays a very important role in lifting the aircraft. The airfoil is designed to increase the velocity of the

Brandon Foster MAE466 2/8/12 HW#2 1) I think about 1000 radial stations are required for a converged calculation. 2) The first plot is of a rotor with linear twist showing the lift coefficient variation with rbar in hover. The second plot is the lift coefficient max along the radius which looks to be about 1.2. The maximum thrust of the rotor in hover in terms of thrust coefficient is 0.0183.

Caughey Sibley School of Mechanical & Aerospace Engineering Cornell University Ithaca‚ New York 14853-7501 These notes provide the background needed to implement a simple vortex-lattice numerical method to determine the properties of thin airfoils. This material is covered in Lecture‚ but is not in the textbook [5]. A summary of results from the analytical theory also is provided‚ as well as a comparison of the thin-airfoil results with those of a complete

------------------------------------------------- Parasitic Drag/Skin Friction ------------------------------------------------- ------------------------------------------------- Parasitic drag is drag caused by moving a solid object through a fluid medium (in the case of aerodynamics‚ more specifically‚ a gaseous medium). Parasitic drag is made up of many components‚ the most prominent being form drag.Skin friction and interference drag are also major components of parasitic drag. -------------------------------------------------

A dragline excavator is a piece of heavy equipment used in civil engineering and surface mining. Draglines fall into two broad categories: those that are based on standard‚ lifting cranes and the heavy units which have to be built on-site. Most crawler cranes with an added winch drum on the front can act as a dragline. These units (like other cranes) are designed to be dismantled and transported over the road on flatbed trailers. Draglines used in civil engineering are almost always of this smaller
