Aircraft Wing Flutter: An Applied Approach 2010-36-0513
In the last decades, the evolution of aircraft design has been
influenced so much by aeroelasticity, and in particular, flutter.
Flutter is a characteristic aircraft phenomenon of external excited
vibrations, working on the resonance gap, which involves the
structural airplane elements and if it was not reported can be the
source of critical failures of wings or control surfaces.
The present paper will give a general vision about flutter
phenomenon in airplanes wings, specifically on planes of the aero
design, which ones usually disregards this kind of study. However,
this study includes an approach to explain the materials and
methods used to find the results.
Using data from aero design planes its possible presents how a
mechanical engineer can use considerations of flutter to the
project and analysis. With support of accelerometers the modal
frequency of wing can be finding and it supplies data and graphs to
justify values to maximum speed recommend and frequencies band that
should be avoid.
