This force is called the "lift" generated by the wing.
As it speeds through the air, each blade generates lift.
To fly, air must flow over the wing and generate lift.
The thinner the air, the faster the plane has to go to generate enough lift to stay up.
There are several ways to explain how an airfoil generates lift.
But the car proved slippery on the faster tracks because its body generated lift.
Like a hot air balloon, blimps use a gas to generate lift.
Because the craft is heavier than air, it must generate lift to overcome its weight.
Some aircraft with wings also employ bodies that generate lift.
In addition, the fan generated lift only from a small area of its surface, lowering overall thrust available.
