This paper studies weight minimization of a composite flying-wing aircraft using bioinspired
arbitrarily shaped spars and ribs, known as SpaRibs, for the internal structural layout design …

The present thesis is the result of my work at the Institute of System Dynamics and Control at
the German Aerospace Center (DLR) in Oberpfaffenhofen, Germany. My thanks go to Prof …

In this work, a new approach for the generation of a generalized state-space
aeroservoelastic model based on tangential interpolation is presented. The resulting system …

This thesis develops and demonstrates an aircraft pre-design process for loads analysis,
load alleviation, structural optimization and fatigue analysis. It is shown that the …

Active control techniques are a key factor in today's aircraft developments to reduce
structural loads and thereby enable highly efficient aircraft designs. Likewise, increasing the …

Considering active gust load alleviation (GLA) during aircraft design offers great potential for
structural weight savings. The effectiveness of a GLA control system strongly depends on the …

Through the combination of passive and active load alleviation techniques, this paper
presents the design, optimization, manufacturing, and update of a flexible composite wind …

Increasing the number and functionality of control surfaces provides great potential to
improve aircraft performance. This, however, complicates the design of the control allocation …

For many aircraft design analyses, mathematical models need to be evaluated numerous
times, either to reflect changes during the design process or to evaluate certain criteria in the …

Accurate prediction of the aerodynamic forces induced by free-stream disturbance has been
a challenge for flight safety. In this paper, a novel data-based approach to model the online …
