Conceptual Multidisciplinary Aircraft Design using Aero-Structural Adjoint-based Method

The biggest problem that airlines and aircraft manufactures have to face up, is how to keep fuel consumption down, without breaking the performance rise. Fuel-burn reduction can be achieved through engine efficiency, aerodynamic performance, lightweight materials, etc. But these solutions cannot b... Read more >>>

MDO and Robust Optimisation of High Pressure Turbine Components

The requirement for ever more efficient gas turbine engines is leading to increased gas path temperatures, creating increasingly hostile environmental conditions for the adjacent turbomachinery and support structures. Cooling air systems are designed to protect vulnerable components from the hot g... Read more >>>

Novel 3D Shapes for MDO of Fans and Compressors

Modern aeroengines are developed to reduce the specific fuel consumption to achieve the aim of reducing the global CO2 emission. One approach is to increase the bypass ratio. Therefore, turbofans are getting larger to propel more flow through the bypass while reducing the exit velocity. The latter... Read more >>>

Robust Multidisciplinary Optimisation of Composite Fan Blades

Using fan blades made of composite materials introduces significant weight saving potentials for the fan blades themselves, but also for the surrounding fan casing. One of the central tasks of the fan casing is to prevent that parts of the blade are penetrating the fuselage or the wing in the case... Read more >>>

MDO Methodology for Incorporation of Crashworthiness Requirements in Aircraft Design

Introduction In the aerospace sector as well as other sectors, such as automotive, there are several requirements that a structure needs to meet. As the need to bring mass (and cost) to a minimum increases, the need to push the limits on the requirements increases as well. Design optimisation ... Read more >>>

Multi-disciplinary Analysis and Optimization of Composite Forward Swept Wings

Despite successful prototypes (Northrop X-29 and Sukhoi Su-47), forward swept wings are not used in recent aircraft development. Forward sweep however features many advantages: it increases aileron effectiveness, it reduces bending moments aft central wing box and it possibly improves the laminar ... Read more >>>

Parameterisation options for aero elastic tailoring

With ambitious environmental goals set by the Horizon 2020 and Flightpath 2050 programs from the European Commission, that target a 75% reduction in CO2 emissions per passenger kilometre by 2050, air framers must come up with more efficient aircraft design. In order to achieve this, new materials ... Read more >>>
