Improving the sustainability of modern air traffic has been one of the urgent topics in the effort of reducing aviation's contribution to global climate change until today. One building block of this task is the prediction and simulation of aircraft operation and its optimization with respect to the effect on the environment. So far, modeling and s...
Published in print by Universitätsverlag der TU Berlin, ISBN 978-3-7983-3036-8 (ISSN 2512-5141). / Aircraft operating as so-called High Altitude Platform Systems (HAPS) have been considered as a complementary technology to satellites since several years. These aircraft can be used for similar communication and monitoring tasks while operating at a ...
Starting from a Finite-Volume Method solving the Navier-Stokes equations for compressible fluid flow and a Finite-Element Method based on quasi one-dimensional Timoshenko beam elements for structural dynamics, a numerical method for coupled aeroelastic problems of flight vehicles is developed. Using the method, extended aerodynamic stability deriva...
A method for the nonlinear analysis of dynamic systems and its application to aircraft is presented. In extension of existing averaging methods this procedure follows the linearizing eigenvalue analysis, but defines the eigenvalue and eigenvector as functions of the deflection from the examined equilibrium. This approach allows the determination of...
