Airfoil

An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils designed for use at different speeds differ in their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be … more »

Its like there's someone up to bat but there's no pitcher
It's like the light is on inside but no one's home
Too late to change can't rearrange the way you're thinking
It's clear to see that you're not rising but you're sinking

You are long gone
I know you're wrong
You don't belong here
You're running on an empty tank of gasoline
You're running on an empty tank of gasoline

You lied and said that it was me but you're to blame
But all the evidence is filed under your name
Too late for you nothing to do but watch the time pass
You waited too long to refuel yourself with gas

You are long gone
I know you're wrong
You don't belong here
You're running on an empty tank of gasoline
You're running on an empty tank of gasoline

It's time to cut the wire
The forest fire has burned the rubber tire
Get a cold drink and relax

It's time to cut the wire
The forest fire has burned the rubber tire
I'm tired of all these facts

Its like there's someone up to bat but there's no pitcher
It's like the light is on inside but no one's home
Too late to change can't rearrange the way you're thinking
It's clear to see that you're not rising but you're sinking

You are long gone
I know you're wrong
You don't belong here
You're running on an empty tank of gasoline
You're running on an empty tank of gasoline
You're running on an empty tank of gasoline
You're running on an empty tank of gasoline
