Supporting MDO through dynamic workflow (re)generation

The use of advancements in computing technology has enabled designers to perform more thorough and more detailed design studies. Multidisciplinary Design Optimization (MDO) architectures provide users with guidelines on how to structure their MDO problem, including the linking of disciplines and how to perform the optimization. However, complex...

Wing aerostructural optimization using the Individual Discipline Feasible architecture

At present, on the aviation market a need exists for lighter and more efficient aircraft than the ones dominating the airspace today. Beside the reduction in operating costs and air pollutants of these new generation aircraft, this reduction in fuel use can result in several advantages with respect to the performance of the aircraft like...

Development of an optimization framework for landing gear design

An opportunity was identified to improve the traditional landing gear design process. Especially in the conceptual design phase, lots of man-hours are consumed by making the same calculations over and over again, for different concepts. Often, an existing gear is therefore used as initial starting point, to simplify the design process. This...

Wing Shape Multidisciplinary Design Optimization

Multidisciplinary design optimizations have shown great benefits for aerospace applications in the past. Especially in the last decades with the advent of high speed computing. Still computational time limits the desire for models with high level of fidelity cannot be always fulfilled. As a conse- quence, fidelity is often sacrificed in order to...

Multidisciplinary Design Optimization in the Conceptual Design Phase: Creating a Conceptual Design of the Blended Wing-Body with the BLISS Optimization Strategy

Traditionally, the aircraft design process is divided into three phases: conceptual, preliminary and detailed design. In each subsequent phase, the fidelity of the analysis tools increases and more and more details of the design geometry are frozen. In each phase a number of design variants is generated, fully analyzing them with the tools...
