Time Line of the Aviation Propeller The aircraft propeller looks like a simple mechanism to the uneducated individual. To the educated, an aircraft propeller represents the highest sophistication in aerodynamics, mechanical engineering and structural design. The creation of the propeller can be traced back to Leonardo da Vinci. Da Vinci\'s \"helical screw\" helicopter is believed to be the ancestor of the air propeller and the helicopter rotor. The first idea of a propulsive airscrew, …showed first 75 words of 1139 total…

Advanced applications of the propeller are currently being experimented by Hamilton Standard. The aviation propeller has constantly evolved with increasing technology. The propeller may be close to achieving its maximum potential with the development of the modern turbo-fan engine. However, today\'s propellers will be in service for many years to come. This article has been a brief overview of this amazing device.
