Preliminary Aircraft Design within a Multidisciplinary and Multifidelity Design Environment

Abstract

In this paper, the preliminary aircraft design tool
\nopenAD is presented. Over the past years the DLR
\nhas developed a multidisciplinary and multifidelity
\ndesign environment for aircraft design to evaluate
\nand assess various concepts and technologies at
\naircraft level. Thereby, a valid and
\nconsistent design can be derived by a minimum set
\nof top-level aircraft requirements. This design
\nenvironment is highly modular where the domain
\nspecific tools are provided and hosted across the
\ndifferent DLR institutes. As part of the design
\nprocess, openAD was developed as the key
\nenabler for overall aircraft design and assessment.
