Process Implementation for the System Evaluation of new Low-Noise STOL Transportation Concepts

Bertsch, Lothar and Schneider, Oliver and Hemmer, Harry and Hepperle, Martin and Macke, Oliver (2009) Process Implementation for the System Evaluation of new Low-Noise STOL Transportation Concepts. CEAS / KATnet II Conference on Key Aerodynamic Technologies, 12.-14. Mai 2009, Bremen, Germany.



The German Aerospace Center (DLR) has initiated the project Quiet Short Take-Off and Landing (QSTOL) to set up a multidisciplinary analysis process for new low-noise STOL transportation concepts. The process chain consists of expert tools from various DLR institutes and their partners which are harmonized in input and output data. Involved disciplines are aircraft design, engine cycle modeling, flight mechanics, air traffic integration, and noise prediction. The influence of aircraft design modifications on flight performance/operational procedures, ground noise impact, and air traffic intergration can be evaluated. Obviously, these diciplines are highly correlated and need to be integrated into one multidisciplinary process. The implementation of this new process along with first applications are addressed in this paper. A conventional medium-range transport aircraft is modified for QSTOL operation. Structural modifications of the airframe and a geared turbofan engine concept are investigated. The effects of these measures on ground noise impact, field performance, and air traffic integration are discussed.
