Abstract

Aircrafts are complex machines in which the overall performances are determined by the cooperation of several subsystems. For the design of modern aircraft, interaction between aerodynamics, structural dynamics, flight dynamics and active controls, is nowadays becoming more and more important, mainly due to the increasing dimensions, the weight savings, and the high flexibility of structures. Thus, subsystems frequencies are very close to each other, and coupled multidisciplinary co-simulations are needed to predict the air-craft performances, even in the preliminary design phase. In this work, a high-fidelity free software co-simulation environment is proposed to simulate coupled aerodynamics and structural dynamics problems. Such a platform is used to verify the performances of an active control system for flutter suppression designed by means of low-fidelity efficient tools.
