Nonlinear Folding Wing Tips for Gust Loads Alleviation [PDF]

Journal of Aircraft, 2015
A recent consideration in aircraft design is the use of folding wing tips with the aim of enabling higher aspect ratio aircraft with less induced drag, but also meeting airport gate limitations. This study builds on previous work investigating the effect of exploiting folding wing tips in-flight as a device to reduce dynamic gust loads, but now with ...
