Predicting Take-Off Noise, Sonic Boom, and Landing Noise of Supersonic Transport Aircraft Concepts

Abstract

In 2023, the German Aerospace Center (DLR) has launched the STORMIE (Supersonic Transport Open Research Models and Impact on Environment) project. Focus of the project is the prediction and minimization of environmental and human impacts of civil supersonic transport. Data generated in the project will be used to inform national and European authorities in order to discuss certification standards for supersonic aircraft within the International Civil Aviation Organization’s Committee on Aviation Environmental Protection (CAEP). In order to assess the environmental impacts, representative civil supersonic business-jet and airliner concepts will be designed. This paper will present an overview of past and ongoing activities conducted at DLR to assess and minimize landing and take-off noise as well as the sonic boom of supersonic aircraft. Numerical methods at different levels of fidelity are applied and will be complemented by listening experiments in a later project stage. First noise-related activities within the STORMIE project are summarized.
