Minimizing the climate impact of the next generation aircraft using novel climate functions for aircraft design

The aircraft’s environmental performance on fleet level is so far completely decoupled from the design process. The climate impact from aviation arising from non-CO2 effects are largely independent from CO2 emissions, but rather depend on the atmospheric state. Previously complex climate-chemistry models were used to evaluate the non-CO2...

Morphing wing design using integrated and distributed trailing edge morphing

The presented study investigates the design and development of an autonomous morphing wing concept developed in the scope of the SmartX project, which aims to demonstrate in-flight performance optimisation with active morphing. To progress this goal, a novel distributed morphing concept with six translation induced camber morphing trailing...

An optimisation strategy for the (in- and out-of-plane) resistance of steel beams in demountable composite floor systems

Demountable and reusable composite floor systems enable the decoupling between the use of construction materials and economic activity, and hereby contribute to the sustainability of the built environment. Efficient material use through optimised cross-section design reduces construction material demand. Demountable steel-concrete composite...

Interactive distributed optimisation for multidisciplinary design

This paper presents the development of a multidisciplinary optimisation system for the Architecture Engineering and Construction (AEC) industry. The system consists of two major components, namely a multidisciplinary optimisation framework and a distributed cloud-based analysis framework. The former utilises an interactive optimisation search...

Conceptual Design Automation: Abstraction complexity reduction by feasilisation and knowledge engineering

In order to keep innovating, engineers are working more and more with engineering software, providing them a way to cut away their routine and repetitive activities. Computer aided design and simulation software are for instance considered standard tools in most engineering companies. Today, to solve complex engineering design problems,...

Efficient Unstructured Hybrid Meshing and its Quality Improvement for Design Optimisation of Turbomachinery

Automatic robust unstructured hybrid meshing is indispensable for the success in design optimisation. In addition, it is important to maintain the mesh quality for deformation of geometry throughout the optimisation process for the reliability of optimal design. Mesh adaptation is useful to capture the flow feature which can highly affect flow...

The use of automatic differentiation for adjoint CFD codes

Optimisation of aerospace designs uses the linear gradients of the minimised objective functionals with respect to the specified design variables. These gradients can be computed using a linearised version (or the adjoint equivalent) of the CFD code that outputs the original objective functionals. The task of generating linear or adjoint code...
