Airfoil Panels


The Airfoil View Panel provides a schematic drawing of the airfoil problem. This schematic displays the airfoil shape and the streamlines of flow around the airfoil. Flow moves from left to right. The airfoil is colored white. The green streamlines flow over the top of the foil and the yellow pass below. The white lines indicate the stagnation streamlines which end on the airfoil surface.


The Airfoil Input Panel controls the shape and attitude of the airfoil displayed in Airfoil View Panel. You can vary all the parameters which affect the lift of an airfoil using the input boxes and sliders.


You can vary the display by using the sliders on the Airfoil View Panel. Use In and Out sliders to zoom the size. The position can be changed with the Left/Right and Up/Down sliders.

As the angle, thickness, or camber are varied, the geometry in the Airfoil View Panel is changed and the value of lift is computed and displayed in the output box and gauge at the bottom. As the airspeed is increased, the lift will change. Varying the altitude changes the local density and the lift generated by the wing. The units for the various parameters are given to the right of the sliders.

The Lift of an airfoil can have a very wide range of values. To obtain the value of the lift, take the number given in the output box at the left and multiply by the number to the right of the gauge. The multiplier is always shown in powers of 10.

For a given altitude, the current Density, Pressure, and Temperature are shown at the bottom of the Airfoil View Panel.
