The Delft University of Technology is developing an MDO tool for the conceptual design of transport aircraft. However, the current program is not able to investigate the influence of the undercarriage design on the weight, drag and geometry of transport aircraft. This research proposes a new design method for the undercarriage, for which a new...

In the aerospace industry, demanding time constraints make it practically impossible to fully explore the design space of aircraft movable surfaces. The hinges, located at the interface of the movable surface, require a time-consuming analysis. This thesis presents a methodology enabling the near instantaneous selection of an optimal hinge. An...

Multidisciplinary Design Analysis and Optimization (MDAO) promises major advances in aircraft design. However, judging from todays aircraft, MDAO is clearly not fully embraced by the industry yet. This is due to technical difficulties (coupling incompatible tools) and non-technical barriers (intellectual property).

Recent research, such...

Multidisciplinary Design Optimization (MDO) frameworks, capable of performing overall aircraft design studies become too complex to be comprehended by a single team of experts. Therefore, there is an increasing need to develop distributed analysis frameworks in which both tools and experts are integrated in a single network. This poses great...

Blended wing body aircraft represent a paradigm shift in jet transport aircraft design. Stepping away from the conventional tube-and-wing philosophy, they promise benefits over existing or future conventional aircraft. The most significant challenge with the concept is the increased coupling between aircraft design disciplines that has...

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...

Current wing design processes are strongly governed by cruise design requirements. This approach to wing design leaves little room for high-lift device design optimization where trade-offs may be required between cruise wing and high-lift wing design. Moreover, the optimization of high-lift devices typically focuses on optimizing flap/slat...

Aircraft concepts with high aspect ratio wings have been investigated more extensively in the recent past, as such configurations would reduce the induced drag significantly. At the same time, the high aspect ratio challenges the wing’s aero-structural stability (flutter). Therefore there is a need to perform aero-structural analysis already...

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...

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...

Due to the ever growing demand for more efficient aircraft novel aircraft concepts have to be explored. By improving design tools the potential of unconventional configurations can be further studied. This requires improvement of conceptual design tools such that more knowledge can be gathered on alternative solutions as early in the design...

The design of the landing gear is one of the prime aspects of aircraft design. Literature describes the design process thoroughly, however the integration of these design methods within an automated design framework has had little focus in literature. Landing gear design includes different engineering disciplines including structures, weights,...

In the last 60 years many new technologies have entered the aerospace industry, but the overall aircraft design remained virtually unchanged. If we compare an aircraft built in the 1960's with the latest generation, they look strikingly similar. Only small evolutionary changes entered the commercial aircraft market. A lot of these changes are...

Research in aircraft design is focusing on novel aircraft configurations in search for a step change in terms of overall transport efficiency. Aircraft design relies heavily on empirical methods, so-called Class 2 methods, to evaluate the performance of a design. Since these methods are based on statistical data their validity is limited when...

One of the main challenges in Multi-disciplinary Design Optimisation (MDO) is the interoperability of heterogeneous simulation tools. Some researches have reported that, due to these interoperability issues, only around 20% of the product development time is spent on analyses and creative design tasks. Clearly, there is a lot to gain, when it...

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...

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...
