Popis: | Given the need to reduce fuel burn and emissions from aircraft drastically, aircraft designers are moving away from conventional tube-and-wing aircraft configurations towards unconventional configurations in search of benefits in terms of fuel burn and emissions. However, conceptual design and optimization of these configurations is still a challenging problem owing to the inability of correlation-based methods to accurately predict the aerodynamics and structural weight of the aircraft. In this paper we present a multi-fidelity design framework that uses finite element-based structural sizing and weight estimation, vortex lattice and CFD-based aerodynamics and automated parametric geometric modeling. These physics based methods are combined with a conceptual design framework to allow realistic design and optimization of unconventional aircraft configurations. We then use this physics-based design framework to perform design and optimization studies on a strut-braced-wing aircraft configuration. |
