Abstract
The structural dimensioning of an airplane will be significantly influenced by gust, maneuver and ground loads. Adaptive load alleviations methods (keyword: 1g-wing) promise the potential reducing the maximum loads and therefore the structural weight. For the appropriate analysis of such load alleviation technologies a multidisciplinary approach is necessary. In order to achieve this objective a process chain for gust encounter simulation is applied using high fidelity methods for the disciplines aerodynamics, structural dynamics and flight mechanics, which are coupled in the time domain. Within multidisciplinary simulations of a generic transport aircraft configuration with and without aileron deflections the influence of vertical gusts on the resultant forces, moments, load distributions on the wing and on the horizontal tail plane are presented.
