How do Aircrafts Fly?
To fly
in the air, aircrafts need power, which is provided by the engines. They
need a
lift to rise from the ground
and stay
in the air. This lift is
provided by
the wings. The aircraft
wings have
a special shape called an
aerofoil. The
top surface of
the wing is curved,
while the bottom is flat.
As the
plane cuts through the
air, the
air that flows over the wing
has to
travel greater distances than
the air
flowing underneath the wing, so it has to travel faster over the top.
This reduces
the pressure above the wing and creates lift At take-off, the engine provides
the power to generate lift. The forward thrust of the engines
balances the
resistance or drag set up by the air.
