This article gives an overview of reduced-order modeling work performed in the DLR project
Digital-X. Parametric aerodynamic reduced-order models (ROMs) are used to predict …

This paper introduces the concept of the design and engineering engine, which is a modular
computational design system to support distributed multidisciplinary design and optimization …

For certification of an aircraft, it has to be demonstrated that its structure can withstand the
loads acting on it without damage. In order to design the structure accordingly, a so called …

For economical and ecological reasons aircraft are required to become more efficient by
reducing fuel consumption and CO 2 emissions. One way to achieve these objectives is to …

The paper presents the control design approaches for the European research project
FLEXOP. The ultimate goal is to develop and apply active flutter suppression and load …

This thesis is concerned with the derivation of nonlinear equations of motion for flexible
aircraft in flight. These equations are intended for the accurate simulation of the flight …

The integration of loads analysis models using so called aerodynamic influence coeffcients
(AICs) is described. These AICs relate a change of normal velocity at panel control points to …

In the field of structural loads analysis, the focus is on accurate modelling of the lift forces, as
they are the main driver of the structural sizing loads. Hence, in many aeroelastic …

In order to investigate the capabilities of a reusable launch system, JAXA, CNES and DLR
have jointly initiated the project CALLISTO (" Cooperative Action Leading to Launcher …

Increasing efficiency is at the core of next generation aircraft development. Aerodynamics
can be improved by high aspect ratio wings, but as these wings are more susceptible to …
