The Environmental Design Space (EDS) is a modeling and simulation environment devised for the design and evaluation of subsonic aircraft. One of the main features that sets it apart from other similar frameworks is its capability to perform aircraft performance and sizing, exhaust emissions, and noise prediction. These three elements are seamlessly executed due to the integration of multiple industry-standard tools. Since its conception in 2008, EDS has been used to support multiple research entities and projects for the evaluation of current and future aircraft concepts and technologies. Its results and assumptions have been calibrated and revised through the years in conjunction with panels of experts in the field. Therefore, it has undergone continuous development that has increased its capability, allowing it to model not only traditional tube-and-wing aircraft, but also unconventional configurations. At the writing of this paper, its capabilities extend beyond standard single and dual spool engines to include geared fans, ultra high bypass turbofans, open rotors, and partially turboelectric propulsion architectures. This paper presents an overview of how EDS has been used to support major research efforts. Then, an approach to develop and calibrate engine and aircraft models to match existing open-source data is presented. Finally, a summary of available advanced engine and aircraft architectures is shown. The results demonstrate EDS capability to create models that closely match existing systems performance, and its flexibility to keep supporting future aircraft design and technology development studies.
