Abstract

Short review of DLR and TU Braunschweig application of a simulation process for aircraft design synthesis with integrated noise prediction capabilities. An existing process is upgraded in order to process external data from high-fidelity computation and measurements. Dedicated engine simulation data for a GTF engine and experimental findings for selected high-lift systems are incorporated into the study. Aircraft performance, e.g., direct operating costs, can now directly be compared to the predicted ground noise levels for different aircraft/engine combinations under consideration. The geared turbofan engine has been simulated on board of conventional tube-and-wing aircraft as well as on board of dedicated low-noise vehicles. It is demonstrated, that the combination of noise shielding and the geared turbofan concept is most effective. The most promising low-noise vehicle of the study is equipped with GTF engines that are shielded by the fuselage and the main wing. Consequently, the influence of the airframe noise sources is increased for this vehicle and any modification in order to reduce the airframe noise becomes especially effective. Application of low-noise airframe technologies to this vehicle reduce the overall aircraft noise as received on the ground.
