- OK, so basically the best way to think of it is that each wing is an airplane wing, and this airfoil allows the boomerang to generate lift.
- airfoil lift
- turbine airfoil
- laminar airfoils
We are essentially burning the airfoil as we fly it, and we are flying it or trying to.

Examples
-
Due to the considerable flow separation illustrated here, the lift of the airfoil is dramatically reduced; the airfoil is stalled.
Academic text (2005) -
The turbine's air-cooled airfoils allow for higher firing temperatures but keep metal temperatures lower than in first-generation engines.
Academic text (2009) -
So it's the angle with which this airfoil has to the air.
-
And that lift force depends on the design of the exact shape of the wings or the airfoil, certainly depends on their size.
-
The testing data gave manufacturers a selection of standard airfoils, many of which found wide use during World War II.
Academic text (2003) -
By the late 1930s, NACA began work on creating airfoils with maximum lift.
Academic text (2003) -
The three-dimensional design of LPT airfoils also holds tremendous promise for achieving improved performance.
Academic text (2009) -
The three-dimensional contouring of turbine airfoils has become commonplace since about 1990.
Academic text (2009) -
The EHD series will use tall, high-performance 17- to 21-meter rotors incorporating advanced airfoils designed specifically for the series.
Academic text (1994) -
The shape of the airfoil helps generate lift as the aircraft moves through the sky.

Etymology
Airfoil combines air ('air') and foil, a word that once meant 'leaf' or a 'thin plate'. So an airfoil is a thin, curved surface like a leaf or sheet that meets the air to create lift and help control a plane or rotor blade.
