When the Wright Brothers invented the airplane, they also had to invent the airplane propeller
. This statement by Orville Wright describes the challenge of producing an aircraft propeller that would provide enough thrust to sustain flight:
If the oscillation is circular, this is similar to the motion of an airplane propeller
. Its rotational axis -- corresponding to the spin -- points into the direction of propagation.
a typical residential wind turbine looks like an airplane propeller
sitting atop a 50 to 120-foot tower.
The rotation axis is off to the side of the wing and parallel to its width, so that it rotates like half of an airplane propeller

Unless the blades of this airplane propeller
can defy gravity and float, the iphone's camera totally distorted reality with this picture.
Imagine if your car had an airplane propeller
in front, instead of a connection from the engine to the wheels.
The range of fans, which look like a sleek airplane propeller
, can be found in Litecraft's dedicated ceiling fan department.
The submerged turbine looks like a cross between an airplane propeller
and a win&hill, with three 10-meter blades that turn with the tides to produce up to 300 kilowatts (kW) of electricity, enough to light and heat about 35 Norwegian homes.
An actual airplane propeller
from a Piper J3-cub, which was given to him as an office-warming gift by a close friend in Japan, hangs just off to the right of his desk.
Dominion's rise from a small one-man operation in 1977 to Alaska's only full-service airplane propeller
shop in 1993 has not been meteoric, but it has been steady.
An example is RTM molds made for short runs of airplane propeller
blades at the Hamilton Standard Group of United Technologies, Windsor Locks, Conn.
