What is Foil sim?

FoilSim is an educational computer program. It is not a design program. FoilSim was built to help students learn how wings work. It produces the correct trends (for example, doubling velocity will quadruple the lift and drag) but it does not give the exact value of lift or drag.

What is airfoil design?

An airfoil (or aerofoil in British English) is any structure designed to manipulate the flow of a fluid to produce a reaction, which in an aircraft’s case, is aerodynamic lift. The wings of fixed-wing aircraft feature airfoil-shaped cross-sections.

What parameters affect CL and CD?

The shape of the wings effect the cl and cd. The wing must be able to slice threw the air but have enough drag to stay in flight. The shape of the wing completely dictates that.

What is X C for airfoil?

x/c varies from 0 at the leading edge to 1.0 at the trailing edge. Cp is plotted “upside-down” with negative values (suction), higher on the plot. (This is done so that the upper surface of a conventional lifting airfoil corresponds to the upper curve.)

How does an airfoil work?

airfoil, also spelled Aerofoil, shaped surface, such as an airplane wing, tail, or propeller blade, that produces lift and drag when moved through the air. An airfoil produces a lifting force that acts at right angles to the airstream and a dragging force that acts in the same direction as the airstream.

What is drag bucket?

In some airfoils, called laminar flow airfoils or low-drag airfoils, the minimum drag coefficient extends over a range of lift coefficients (Figure below). This feature is called ‘Drag bucket’.

What is Rho in lift?

In many textbooks on aerodynamics, the density is given by the Greek symbol “rho” (Greek for “r”). The combination of terms “density times the square of the velocity divided by two” is called the dynamic pressure and appears in Bernoulli’s pressure equation.

What is the purpose of the foilsim program?

What is the difference between foilsim II and foil Sim III?

This is the first release version for FoilSim III and includes a drag calculation which was not available in FoilSim II. Earlier versions of FoilSim III were developmental versions and not released to the public. With the release of FoilSim III, upgrades and revisions will cease for FoilSim II.

How do I download the latest version of foilsim?

FoilSim is available for downloading onto your computer. Here is the procedure to follow: Click Here to download a copy of Version 1.5a, FoilSim III Applet (lift plus drag). Click Here to download a copy of the older Version 1.5, FoilSim II Applet (lift only).

Is foilsim II available for students?

Again, the student does not have to select types of output, or interpret graphs. FoilSim II is still available for students who are learning about the lift of airfoils and wings. This version calculates the lift of an airfoil based on user inputs of flow conditions and wing geometry.
