DLR´s capabilities in aircraft design are spread over many institutes which are located at various sites in Germany. With the Mephisto project DLR aims at combining this distributed expertise. The paper at hand reports on one aspect of this effort, the reduction of the infrared (IR) signature of a wing only configuration´s propulsion system. This was achieved through the collaboration of three DLR institutes, namely the Institute of Propulsion Technology (Cologne), Institute of Aerodynamics and Flow Technology (Göttingen), and the Remote Sensing Technology Institute (Oberpfaffenhofen). The work on engine design performed at the Institute of Propulsion Technology is described in a separate paper. Thus, the focus here is on the achievements in infrared modeling and the aerodynamic design, especially of the exhaust system. The paper presents the capabilities of MIRA (Model for Infrared Signature Analysis). This tool had certain capabilities added and then was applied in Mephisto to predict the IR signature of different variants of the configuration´s exhaust duct. The result of this design effort is a large reduction of the IR emission caused by the exhaust gases. However, the simulations show that low observability is not yet achieved.
