Abstract

The development of lighter and more efficient transport aircraft has led to an increasedfocus on gust load alleviation. A recent consideration in aircraft design is using hinged wingtip devices to increase the aspect ratio, improving aircraft performance. Furthermore, numerical experimental tests ha...
