UNICADO: multidisciplinary analysis in conceptual aircraft design

Abstract In this paper, different iterative methods, so-called architectures, within the multidisciplinary analysis in conceptual aircraft design of UNICADO software are elaborated, applied and analyzed. Possible execution sequences sequential method (Gauss-Seidel architecture) derived via a graph-based algorithm combination with expert knowledge. Sensitivities disciplines analyzed permitted residual for stable convergence characteristic is derived. Prerequisites application parallel method, Jacobi architecture conducted. Runtime characteristics Gauss-Seidel evaluated. A damping to enhance characteristics. The architectures used two aircraft, CSR CSMR, an iteration accuracy 2.5e–3. For these use cases studied, converges more stably faster than is, therefore, favorable. implemented oscillates does not converge. Only achieved. If time loop increases, e.g., when using higher fidelity methods design, choice must be re-evaluated.
