In 1913, they had created a vortex-sheet theory of aircraft propellers.

At the time, Hamilton was the largest manufacturer of aircraft propellers in the world.

He also diversified from software into innovative aircraft propeller design.

This work had significant application in developing blade forms for aircraft propellers.

Several people identify it as part of the specifications for a new aircraft propeller worth a great deal to a "foreign power".

Aircraft propellers mounted on high platforms are used by other growers.

The background vibration from the four aircraft propellers was no longer audible.

He contributed significantly to the development of aircraft propellers.

An aircraft propeller operates as the source of thrust that moves the plane forward.

Model aircraft propellers are usually specified as diameter x pitch, given in inches.

Five forces act on the blades of an aircraft propeller in motion, they are:

This speed is considered the typical maximum rpm for a single engine aircraft propeller.

It was attached, roughly at light aircraft propeller height, to the framework of the old control tower itself.

Helicopter rotors operate in a much more challenging environment than a normal aircraft propeller.

The company started producing aircraft propellers in 1983 under the Ultra-Prop brand.

Ice can also accumulate on helicopter rotor blades and aircraft propellers.

During the war, Yamaha designed wooden aircraft propellers.

This then was the direct ancestor of the helicopter rotor and the aircraft propeller."

Honda also aided the war effort by assisting other companies in automating the production of military aircraft propellers.

His main research interests included modelling vibrations, acoustics and aerodynamics of aircraft propellers.

A few feet from my head, an aircraft propeller protruded from a girder and slowly stirred the heavy air.

Hoffman Propeller is a German manufacturer of aircraft propellers.

During the first world war, de Monge engineered, designed and produced aircraft propellers, selling some 40.000 to the French government.

The highest aspect ratio man-made wings are aircraft propellers in their most extreme form as helicopter rotors.

This allows the use of small displacement internal combustion automotive engines to turn aircraft propellers within an efficient speed range.
