Moving an EP-3E Orion's number four engine as part of pre-flight checks
A
propeller
makes an
aircraft
,
ship
, or
submarine
in
water
or
air
go by making a big wind or a strong stream. It does this by turning two or more
wings
very quick. The blades of a propeller act as rotating
wings
, and produce force through application of both
Bernoulli's principle
and
Newton's third law
, generating a difference in pressure between the forward and rear surfaces of the
airfoil
-shaped blades.
