Multi-fidelity design optimization of a long-range blended wing body aircraft with new airframe technologies
Multi-fidelity design optimization of a long-range blended wing body aircraft with new airframe technologies
Within the German Cluster of Excellence SE²A (Sustainable and Energy Efficient Aviation), three reference aircraft have been initially designed to study promising technologies for future sustainable air transport systems. In this paper, the design optimization of one of these reference aircraft, a long-range blended wing body aircraft, is presented. The design optimization is executed using the multi-fidelity aircraft design code SUAVE with a connection to the CFD code SU2. The conceptual design of the BWB aircraft is performed within the SUAVE framework, where the influence of the new technologies, such as hybrid laminar flow, active load alleviation, boundary layer ingestion, and new materials and structures on the aircraft performance and fuel consumption is investigated. In the second step, the initially designed BWB aircraft is improved by an aerodynamic shape optimization using the SU2 CFD code. In the third step, the performance of the optimized aircraft is evaluated again using the SUAVE code.

Abstract
Within the German Cluster of Excellence SE²A (Sustainable and Energy Efficient Aviation), three reference aircraft have been initially designed to study promising technologies for future sustainable air transport systems. In this paper, the design optimization of one of these reference aircraft, a long-range blended wing body aircraft, is presented. The design optimization is executed using the multi-fidelity aircraft design code SUAVE with a connection to the CFD code SU2. The conceptual design of the BWB aircraft is performed within the SUAVE framework, where the influence of the new technologies, such as hybrid laminar flow, active load alleviation, boundary layer ingestion, and new materials and structures on the aircraft performance and fuel consumption is investigated. In the second step, the initially designed BWB aircraft is improved by an aerodynamic shape optimization using the SU2 CFD code. In the third step, the performance of the optimized aircraft is evaluated again using the SUAVE code.
