Statics and Rotational Dynamics of Composite Beams
A helicopter, with its capability of vertical take-off and landing, is a crucial means of
aerial transportation. In fire-fighting rescue operations and missions for helping survivors of an earthquake or an avalanche, helicopters have played vital roles. The
expansion of the domain of the application of helicopters, however, faces a few
serious constraints; among them is the relatively poor ride quality due to severe
vibration and noise. Vibration can reduce the fatigue life of structural components and
hence increase the operating costs. Furthermore, environmental consequences of
noise and vibration have limited the range of application and the velocity of helicopters. That is why reducing noise and vibration is a major goal in the design of
helicopters.
